A new plan for African cities: The Ethiopia Urban Expansion Initiative

A new plan for African cities: The Ethiopia Urban Expansion Initiative. Patrick Lamson-Hall et al. Urban Studies, https://doi.org/10.1177/0042098018757601

Abstract: Recent research indicates that a simplified approach to urban planning in Sub-Saharan African cities can address the challenges of rapid urban growth. Current plans focus too heavily on the existing area of the city and offer unrealistic agendas for future urban growth, such as densification, containment and high-rise development; plans that are often too complicated and too costly to be deployed in a developing-world context. In response, New York University and the Government of Ethiopia have created a programme to deploy a simple methodology called Making Room for Urban Expansion in 18 Ethiopian cities that are experiencing rapid growth. The programme is called the Ethiopia Urban Expansion Initiative. The Initiative set aside a number of standard planning objectives and instead focused only on expanding city boundaries to include adequate land for expansion, designing and protecting a network of arterial roads spaced approximately 1 km apart, and identifying and protecting environmentally sensitive open spaces. These efforts focused on areas that had not yet been occupied by development. This article reports on the preliminary results from the four Ethiopian cities participating in the Initiative that began in 2013. The results from the first four participating cities show that simple plans can lead to the creation of new arterial roads, increasing access to peripheral land and potentially bringing the available land supply in line with projected growth. These activities can be done at the local level and implemented with limited support from consultants and from the regional and national government, and it requires minimal public investment.

Political correspondence between married couples and parent- offspring agreement have both increased substantially in the polarized era; the principal reason for increased spousal correspondence is mate selection based on politics


The Home as a Political Fortress; Family Agreement in an Era of Polarization. Shanto Iyengar, Tobias Konitzer, Kent Tedin. https://zapdoc.tips/the-home-as-a-political-fortress-family-agreement-in-an-era.html

Abstract: The manifestations of party polarization in America are well known: legislative gridlock, harsh elite rhetoric, and at the level of the electorate, increasing hostility across the partisan divide. We investigate the ramifications of polarization for processes of family socialization. Using the classic 1965 Youth-Parent Political Socialization Panel data as a baseline, we employ original national surveys of spouses and offspring conducted in 2015 supplemented by the 2014 and 2016 TargetSmart national voter files to demonstrate that political correspondence between married couples and parent- offspring agreement have both increased substantially in the polarized era. We further demonstrate that the principal reason for increased spousal correspondence is mate selection based on politics. Spousal agreement, in turn, creates an ”echo chamber” that facilitates intergenerational continuity. Overall, our results suggest a vicious cycle by which socialization exacerbates party polarization.

Analytic atheism: A cross-culturally weak and fickle phenomenon?

Analytic atheism: A cross-culturally weak and fickle phenomenon? Will M. Gervais et al. Judgment and Decision Making, Vol. 13, No. 3, May 2018, pp. 268-274. http://journal.sjdm.org/18/18228/jdm18228.html

Abstract: Religious belief is a topic of longstanding interest to psychological science, but the psychology of religious disbelief is a relative newcomer. One prominently discussed model is analytic atheism, wherein cognitive reflection, as measured with the Cognitive Reflection Test, overrides religious intuitions and instruction. Consistent with this model, performance-based measures of cognitive reflection predict religious disbelief in WEIRD (Western, Educated, Industrialized, Rich, & Democratic) samples. However, the generality of analytic atheism remains unknown. Drawing on a large global sample (N = 3461) from 13 religiously, demographically, and culturally diverse societies, we find that analytic atheism as usually assessed is in fact quite fickle cross-culturally, appearing robustly only in aggregate analyses and in three individual countries. The results provide additional evidence for culture’s effects on core beliefs.

The non-effects of repeated exposure to the Cognitive Reflection Test: We do not improve scores

The non-effects of repeated exposure to the Cognitive Reflection Test. Andrew Meyer, Elizabeth Zhou, Shane Frederick. Judgment and Decision Making, Vol. 13, No. 3, May 2018, pp. 246-259. http://journal.sjdm.org/18/18228a/jdm18228a.html

Abstract: We estimate the effects of repeated exposure to the Cognitive Reflection Test (CRT) by examining 14,053 MTurk subjects who took the test up to 25 times. In contrast with inferences drawn from self-reported prior exposure to the CRT, we find that prior exposure usually fails to improve scores. On average, respondents get only 0.024 additional items correct per exposure, and this small increase is driven entirely by the minority of subjects who continue to spend time reflecting on the items. Moreover, later scores retain the predictive validity of earlier scores, even when they differ, because initial success and later improvement appear to measure the same thing.

Reports of Recovered Memories of Abuse in Therapy in a Large Age-Representative U.S. National Sample: Therapy Type and Decade Comparisons

Reports of Recovered Memories of Abuse in Therapy in a Large Age-Representative U.S. National Sample: Therapy Type and Decade Comparisons. Lawrence Patihis, Mark H. Pendergrast. Clinical Psychological Science, https://doi.org/10.1177/2167702618773315

Abstract: The potential hazards of endeavoring to recover ostensibly repressed memories of abuse in therapy have previously been documented. Yet no large survey of the general public about memory recovery in therapy has been conducted. In an age-representative sample of 2,326 adults in the United States, we found that 9% (8% weighted to be representative) of the total sample reported seeing therapists who discussed the possibility of repressed abuse, and 5% (4% weighted) reported recovering memories of abuse in therapy for which they had no previous memory. Participants who reported therapists discussing the possibility of repressed memories of abuse were 20 times more likely to report recovered abuse memories than those who did not. Recovered memories of abuse were associated with most therapy types, and most associated with those who reported starting therapy in the 1990s. We discuss possible problems with such purported memory recovery and make recommendations for clinical training.

Event-related, contextual, demographic, and dispositional predictors of the desire to punish perpetrators of immoral deeds in daily life, as well as connections among the desire to punish, moral emotions, and momentary well-being

Moral Punishment in Everyday Life. Wilhelm Hofmann et al. Personality and Social Psychology Bulletin,  https://doi.org/10.1177/0146167218775075

Abstract: The present research investigated event-related, contextual, demographic, and dispositional predictors of the desire to punish perpetrators of immoral deeds in daily life, as well as connections among the desire to punish, moral emotions, and momentary well-being. The desire to punish was reliably predicted by linear gradients of social closeness to both the perpetrator (negative relationship) and the victim (positive relationship). Older rather than younger adults, conservatives rather than people with other political orientations, and individuals high rather than low in moral identity desired to punish perpetrators more harshly. The desire to punish was related to state anger, disgust, and embarrassment, and these were linked to lower momentary well-being. However, the negative effect of these emotions on well-being was partially compensated by a positive indirect pathway via heightened feelings of moral self-worth. Implications of the present field data for moral punishment research and the connection between morality and well-being are discussed.

A Meta-Analytic Comparison of Partisan Bias in Liberals & Conservatives: Liberals and conservatives showed no difference in mean levels of bias across studies. Moderator analyses reveal this pattern to be consistent across a number of different methodological variations & political topics

At Least Bias Is Bipartisan: A Meta-Analytic Comparison of Partisan Bias in Liberals and Conservatives. Peter H. Ditto et al. Perspectives on Psychological Science, https://doi.org/10.1177/1745691617746796

Abstract: Both liberals and conservatives accuse their political opponents of partisan bias, but is there empirical evidence that one side of the political aisle is indeed more biased than the other? To address this question, we meta-analyzed the results of 51 experimental studies, involving over 18,000 participants, that examined one form of partisan bias—the tendency to evaluate otherwise identical information more favorably when it supports one’s political beliefs or allegiances than when it challenges those beliefs or allegiances. Two hypotheses based on previous literature were tested: an asymmetry hypothesis (predicting greater partisan bias in conservatives than in liberals) and a symmetry hypothesis (predicting equal levels of partisan bias in liberals and conservatives). Mean overall partisan bias was robust (r = .245), and there was strong support for the symmetry hypothesis: Liberals (r = .235) and conservatives (r = .255) showed no difference in mean levels of bias across studies. Moderator analyses reveal this pattern to be consistent across a number of different methodological variations and political topics. Implications of the current findings for the ongoing ideological symmetry debate and the role of partisan bias in scientific discourse and political conflict are discussed.

Do Attitudes Toward Societal Structure Predict Beliefs About Free Will and Achievement? Evidence from the Indian Caste Syste

Srinivasan, Mahesh, Yarrow Dunham, Catherine Hicks, and David Barner 2018. “Do Attitudes Toward Societal Structure Predict Beliefs About Free Will and Achievement? Evidence from the Indian Caste System”. PsyArXiv. May 31. doi:10.17605/OSF.IO/43VDN

Abstract: Intuitive theories about the malleability of intellectual ability affect our motivation and achievement in life. But how are such theories shaped by the culture in which an individual is raised? We addressed this question by exploring how Indian children’s and adults’ attitudes toward the Hindu caste system – and its deterministic worldview – are related to differences in their intuitive theories. Strikingly, we found that, beginning at least in middle school and continuing into adulthood, individuals who placed more importance on caste were more likely to adopt deterministic intuitive theories. We also found a developmental change in the scope of this relationship, such that in children, caste attitudes were linked only to abstract beliefs about personal freedom, but that by adulthood, caste attitudes were also linked to beliefs about the potential achievement of members of different castes, personal intellectual ability, and personality attributes. These results are the first to directly relate the societal structure in which a person is raised to the specific intuitive theories they adopt.


Wealth, Slave Ownership, and Fighting for the Confederacy: Modest increases of wealth among the poorest individuals affects their propensity to fight

Wealth, Slave Ownership, and Fighting for the Confederacy: An Empirical Study of the American Civil War. Andrew B. Hall, Connor Hu, Shiro Kuriwaki. February 10, 2018.

Abstract: How did personal wealth affect the likelihood southerners fought for the Confederate Army inthe American Civil War? We offer competing accounts for how we should expect individual wealth, in the form of land, and atrociously, in slaves, to a ect white men's decisions to join the Confederate Army. We assemble a dataset on roughly 3.9 million white citizens in Confederate states, and we show that slaveowners were more likely to  ght in the Confederate Army than non-slaveowners. To see if these links are causal, we exploit a randomized land lottery in 19th-century Georgia. Households of lottery winners owned more slaves in 1850 and were more likely to have sons who fought in the Confederate Army than were households who did not win the lottery. Our results suggest that for wealthy southerners, the stakes associated with the conflict's threat to end the institution of slavery overrode the incentives to free-ride and to avoid paying the costs of war.

Arabian babblers (a bird) concealed 100% of copulations; did not prefer to copulate under shelters; concealed mating solicitations from adult conspecifics; and subordinates did not attack dominants who courted the female

Why conceal? Evidence for concealed sex by dominant Arabian babblers (Turdoides squamiceps). Yitzchak Ben Mocha, Roger Mundry, Simone Pika. Evolution and Human Behavior, https://doi.org/10.1016/j.evolhumbehav.2018.05.009

Abstract: Striking uniformity exists in humans' preference to conceal sexual activity from conspecifics' view. Yet, little is known about the selective pressures acting upon its evolution. To investigate this question, we studied the cooperatively breeding Arabian babbler (Turdoides squamiceps), which has been suggested being the only other species where dominant individuals conceal sex regularly. We examined whether birds indeed conceal sex and tested different hypotheses, postulating that sex concealment functions to avoid predators, signal dominance status, or to avoid social interference. The results showed that birds concealed 100% of copulations; did not prefer to copulate under shelters; concealed mating solicitations from adult conspecifics; and that subordinates did not attack dominants who courted the female. We argue that none of the hypotheses tested explains our findings satisfactorily and postulate that dominants conceal sex to maintain cooperation with those helpers they prevent from mating. Empirical desiderata for testing this ‘Cooperation-Maintenance’ hypothesis are discussed.

Sexual assault interventions may be doing more harm than good with high-risk males

Sexual assault interventions may be doing more harm than good with high-risk males. Neil Malamuth, Mark Huppin, Daniel Linz. Aggression and Violent Behavior, https://doi.org/10.1016/j.avb.2018.05.010

Highlights
•    With high-risk men, currently used sexual assault interventions are problematic.
•    These interventions appear to be having opposite than intended effects.
•    Such boomerang effects are likely due to these men's hostile reactance.
•    Reactance may underlie both their sexual violence and responses to interventions.
•    Failure to acknowledge this danger may be due to a lack of suitable strategy.

Abstract: Based on legal requirements and other considerations, there have been many well-meaning interventions intended to reduce sexual assault on university campuses throughout the US. There is no legal requirement, however, to evaluate the effectiveness of these programs, and few evaluations have been conducted. Those that have suggest that at best only a small number of these interventions have been effective and those involve bystander interventions. More importantly, there has been very little research examining the effects of such interventions on men at high risk for sexual aggression, who presumably are a key target of such interventions. Research on similar campaigns in other domains should have alerted investigators to the possibility of boomerang reactance effects wherein interventions can actually have the opposite of the intended effects for high-risk college males. The few studies that directly have examined this possibility indeed are supportive of the substantial likelihood of such negative effects. Commonly used interventions may fail with high-risk men because they are likely to generate “hostility reactance” — one of the key causes of both sexual violence itself and the unintended adverse effects of the interventions. We raise the question of why universities have failed to address this possible effect of interventions and why previous reviews have not highlighted this possible danger.

Subjective life expectancy and actual mortality: People is quite accurate, but those with more education shrink their expectation

Subjective life expectancy and actual mortality: results of a 10-year panel study among older workers. Hanna van Solinge, Kène Henkens. European Journal of Ageing, June 2018, Volume 15, Issue 2, pp 155–164. https://link.springer.com/article/10.1007/s10433-017-0442-3

Abstract: This research examined the judgemental process underlying subjective life expectancy (SLE) and the predictive value of SLE on actual mortality in older adults in the Netherlands. We integrated theoretical insights from life satisfaction research with existing models of SLE. Our model differentiates between bottom-up (objective data of any type) and top-down factors (psychological variables). The study used data from the first wave of the Netherlands Interdisciplinary Demographic Institute Work and Retirement Panel. This is a prospective cohort study among Dutch older workers. The analytical sample included 2278 individuals, assessed at age 50–64 in 2001, with vital statistics tracked through 2011. We used a linear regression model to estimate the impact of bottom-up and top-down factors on SLE. Cox proportional hazard regression was used to determine the impact of SLE on the timing of mortality, crude and adjusted for actuarial correlates of general life expectancy, family history, health and trait-like dispositions. Results reveal that psychological variables play a role in the formation of SLE. Further, the results indicate that SLE predicts actual mortality, crude and adjusted for socio-demographic, biomedical and psychological confounders. Education has an additional effect on mortality. Those with higher educational attainment were less likely to die within the follow-up period. This SES gradient in mortality was not captured in SLE. The findings indicate that SLE is an independent predictor of mortality in a pre-retirement cohort in the Netherlands. SLE does not fully capture educational differences in mortality. Particularly, higher-educated individuals underestimate their life expectancy.

Trends in flood losses in Europe over the past 150 years: There is large underreporting of smaller floods beyond most recent years

Trends in flood losses in Europe over the past 150 years. Dominik Paprotny, Antonia Sebastian, Oswaldo Morales-Nápoles & Sebastiaan N. Jonkman. Nature Communications, volume 9, Article number: 1985 (2018). DOI:10.1038/s41467-018-04253-1, https://www.nature.com/articles/s41467-018-04253-1

Abstract: Adverse consequences of floods change in time and are influenced by both natural and socio-economic trends and interactions. In Europe, previous studies of historical flood losses corrected for demographic and economic growth (‘normalized’) have been limited in temporal and spatial extent, leading to an incomplete representation of trends in losses over time. Here we utilize a gridded reconstruction of flood exposure in 37 European countries and a new database of damaging floods since 1870. Our results indicate that, after correcting for changes in flood exposure, there has been an increase in annually inundated area and number of persons affected since 1870, contrasted by a substantial decrease in flood fatalities. For more recent decades we also found a considerable decline in financial losses per year. We estimate, however, that there is large underreporting of smaller floods beyond most recent years, and show that underreporting has a substantial impact on observed trends.

Are Men’s Religious Ties Hormonally Regulated? It seems that too much androgen load reduces those ties. Author think it is causal, not just correlation.

Are Men’s Religious Ties Hormonally Regulated? Aniruddha Das. Adaptive Human Behavior and Physiology, https://link.springer.com/article/10.1007/s40750-018-0094-3

Abstract

Objectives: Studies based on the “challenge hypothesis” have linked men’s androgens—testosterone and DHEA—to short term mating and antisocial behaviors. Causal direction at a given stage of the life cycle remains ambiguous. Religion is a major social institution through which actions violating social norms are controlled. Thus, ties to this institution may be lower among men with higher androgen levels. The present study queried these linkages.

Procedures: Data were from the 2005–2006 and 2010–2011 waves of the National Social Life, Health and Aging Project (NSHAP), a national probability sample of older U.S. adults. Analysis was through autoregressive cross-lagged panel models (minimum N = 1071).

Results: Higher baseline levels of both testosterone and DHEA prospectively predicted religious ties, whether measured through attendance at services or network connections to clergy. Moreover, contrary to arguments of sociocultural modulation of androgens, the pattern of associations was most consistent with hormonal causation of religious connections. Results were robust to a range of time invariant and time varying confounders, including demographics, hormone supplements, and physical health.

Conclusions: Findings add to the growing evidence that religiosity may have physiological and not simply psychosocial roots. Implications for hormonal confounding of previously published religion-deviance linkages, and for neuroendocrine underpinnings of population-level social and cultural patterns, are discussed.


Mate copying has been documented in female Drosophila melanogaster; we report on experimental evidence for mate copying in males of this species in which females can actively reject males and prevent copulation

Mate copying in Drosophila melanogaster males. Sabine Nöbel, Mélanie Allain, Guillaume Isabel, Etienne Danchin. Animal Behaviour, Volume 141, July 2018, Pages 9–15. https://doi.org/10.1016/j.anbehav.2018.04.019

Highlights
•    Reported evidence of male mate copying is rare, but common in females of many taxa.
•    We provide first evidence for male mate copying in D.melanogaster.
•    Measuring courtship behaviour is a good indicator to evaluate male mate choice.

Abstract: To assess potential mates' quality individuals can observe sexually interacting conspecifics. Such social information use is called mate copying and occurs when observer individuals witnessing sexual interactions of conspecifics later show a mating preference for mates that were seen mating. Most studies have focused on female mate copying, as females are usually the choosy sex. However, much less is known about the existence of male mate copying, probably because of the usual strong asymmetry in sex roles. Mate copying has been documented in female Drosophila melanogaster, and here we report on experimental evidence for mate copying in males of this species in which females can actively reject males and prevent copulation. As mate choice implies high costs for males we assumed that they perform mate copying as well. We created two artificial female phenotypes by randomly dusting females with green or pink powders, and virgin naïve observer males were given the opportunity to see a demonstrator male choosing between a pink and a green demonstrator female. Immediately afterwards, observer males were given the choice between two new females, one of each colour. To circumvent the difficulty of determining actual male mate preference, we used two complementary indices of male mate choice, both of which provided evidence for male mate copying. Informed observer males showed a bias towards females of the colour they saw being chosen during demonstrations, while uninformed males chose randomly between pink and green females. This suggests that male fruit flies can also perform mate copying. Although significant, our results in males were less clear-cut than in females in previous studies. However, like females, D. melanogaster males can mate copy based on a single observation. The importance and generality of such mate copying abilities in nature, and their potential impact on the evolution of Drosophila and probably other invertebrates, need further exploration.

Laughter Is (Powerful) Medicine: the Effects of Humor Exposure on the Well-being of Victims of Aggression

Laughter Is (Powerful) Medicine: the Effects of Humor Exposure on the Well-being of Victims of Aggression. David Cheng, Rajiv Amarnani, Tiffany Le, Simon Restubog. Journal of Business and Psychology, https://link.springer.com/article/10.1007/s10869-018-9548-7

Abstract: Aggression at work is an expensive and widespread problem. While a large body of research has studied its antecedents and consequences, few studies have examined what victims can do to help mitigate the damage once it has occurred. Many practitioners and scholars have suggested that workers seek out humor to help them deal with the impact of stressors such as aggression, but little is known about whether humor can actually help victims deal with the psychological damage caused by aggression in the workplace. This paper presents a programmatic series of four experimental studies that examine whether and how exposure to humorous stimuli improves well-being among victims of interpersonal aggression by integrating the superiority theory of humor with Lazarus and Folkman’s transactional model of stress and coping. Study 1 (N = 84 students) showed that exposure to humor had a positive effect on well-being in a sample based in the Philippines. Consistent with theoretical prescriptions from the superiority theory of humor, this effect was mediated by increased momentary sense of power. Study 2 (N = 205 students) found the same positive effects of humor exposure on well-being in a sample based in Australia even when manipulating perpetrator power. These findings were replicated in studies 3 (N = 175 MTurk workers) and 4 (N = 235 MTurk workers) among a diverse sample of workers based in the USA.

Dark Personality Voters Find Dark Politicians More Relatable and Fit for Office

Dark Personality Voters Find Dark Politicians More Relatable and Fit for Office. William Hart, Kyle Richardson, , Gregory K. Tortoriello. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2018.05.007

Highlights
•    Dark personalities evaluate dark characteristics in politicians less negatively.
•    Dark personalities perceive nice (vs. dark) politicians as less relatable.
•    Dark personalities show a reduced preference for nice (vs. dark) politicians.
•    Findings supported and extended political congruency theory.

Abstract: We tested the scope of the congruency model of political preference by examining how people high in various dark personalities evaluate political candidates with dark characteristics. In Study 1, participants high in dark personalities reported enhanced self-possession of dark characteristics and, in general, more tolerance of those characteristics in politicians. In Study 2, although participants viewed a wholesome (vs. dark) politician as more similar to the self and likeable, this effect diminished as participants indicated greater possession of dark personalities. Exploratory analyses involving other perceiver traits (self-esteem, political conservatism/liberalism) yielded additional insights about tolerance for dark politicians. Findings contribute to understanding how people high in dark personalities evaluate others and offer a novel perspective on similarity-liking effects in candidate evaluation.

Average Associations Between Sexual Desire, Testosterone, and Stress in Women and Men Over Time: Testosterone negatively predicted partnered desire in women, not effect in men

Average Associations Between Sexual Desire, Testosterone, and Stress in Women and Men Over Time. Jessica C. Raisanen et al. Archives of Sexual Behavior, https://link.springer.com/article/10.1007/s10508-018-1231-6

Abstract: Sexual desire and testosterone are widely assumed to be directly and positively linked to each other despite the lack of supporting empirical evidence. The literature that does exist is mixed, which may result from a conflation of solitary and dyadic desire, and the exclusion of contextual variables, like stress, known to be relevant. Here, we use the Steroid/Peptide Theory of Social Bonds as a framework for examining how testosterone, solitary and partnered desire, and stress are linked over time. To do so, we collected saliva samples (for testosterone and cortisol) and measured desire as well as other variables via questionnaires over nine monthly sessions in 78 women and 79 men. Linear mixed models showed that testosterone negatively predicted partnered desire in women but not men. Stress moderated associations between testosterone and solitary desire in both women and men, but differently: At lower levels of stress, higher average testosterone corresponded to higher average solitary desire for men, but lower solitary desire on average for women. Similarly, for partnered desire, higher perceived stress predicted lower desire for women, but higher desire for men. We conclude by discussing the ways that these results both counter presumptions about testosterone and desire but fit with the existing literature and theory, and highlight the empirical importance of stress and gender norms.

Many forms of implicit bias training are aimed at changing individuals’ implicit biases (treated as trait-like attributes of the person); but implicit bias may not be a stable attribute of individuals, but may better characterize social environments than people

Policy Insights From Advances in Implicit Bias Research. B. Keith Payne, Heidi A. Vuletich. Policy Insights from the Behavioral and Brain Sciences, https://doi.org/10.1177/2372732217746190

Abstract: Implicit bias, which refers to mental associations that can lead to unintentional discrimination, has become a focus as many organizations and institutions try to reduce disparities and increase inclusiveness. Many forms of implicit bias training are aimed at changing individuals’ implicit biases. This approach treats implicit bias as a trait-like attribute of the person. Recent theoretical advances in understanding implicit bias, however, suggest that implicit bias may not be a stable attribute of individuals. Instead, implicit bias may better characterize social environments than people. Understanding implicit bias as a cultural phenomenon, rather than a fixed set of beliefs, has important policy implications. Most notably, the best approaches for reducing the harm of implicit bias should aim at changing social contexts rather than changing people’s minds. Here, we highlight some considerations of this new understanding of implicit bias for policy makers aiming to reduce disparities and increase inclusion.

In the spiritual condition, as compared with the neutral-relaxing condition, we see reduced activity in the left inferior parietal lobule (IPL), a result that suggests the IPL may contribute importantly to perceptual processing and self-other representations during spiritual experiences

Neural Correlates of Personalized Spiritual Experiences. Lisa Miller, Iris M Balodis, Clayton H McClintock, Jiansong Xu, Cheryl M Lacadie, Rajita Sinha, Marc N Potenza. Cerebral Cortex, bhy102, https://doi.org/10.1093/cercor/bhy102


Abstract: Across cultures and throughout history, human beings have reported a variety of spiritual experiences and the concomitant perceived sense of union that transcends one’s ordinary sense of self. Nevertheless, little is known about the underlying neural mechanisms of spiritual experiences, particularly when examined across different traditions and practices. By adapting an individualized guided-imagery task, we investigated neural correlates of personally meaningful spiritual experiences as compared with stressful and neutral-relaxing experiences. We observed in the spiritual condition, as compared with the neutral-relaxing condition, reduced activity in the left inferior parietal lobule (IPL), a result that suggests the IPL may contribute importantly to perceptual processing and self-other representations during spiritual experiences. Compared with stress cues, responses to spiritual cues showed reduced activity in the medial thalamus and caudate, regions associated with sensory and emotional processing. Overall, the study introduces a novel method for investigating brain correlates of personally meaningful spiritual experiences and suggests neural mechanisms associated with broadly defined and personally experienced spirituality.

For the spiritual script, participants were given the following
instructions:


“We would like you to describe a situation in which you felt a strong connection with a higher power or a spiritual presence. Spiritual states are those that through a felt-sense connect you to something bigger than oneself, a oneness, or strong force which may be experienced as an energy, force, higher power, G-d, deity or transcendent figure or consciousness. Such states may be experienced in places of worship, at home, in your daily life, or outdoors in nature. Choose a personal lived situation that you directly experienced, whether others were present or not. Also, include in your description the bodily sensations you have experienced in these situations.


Some common experiences of transcendent connection include a two-way relationship with a higher power, a felt-sense of oneness in nature by the ocean or atop a mountain, being in a zone of intense physical activity (such as sports or yoga), sudden awareness, bodily felt connectivity or buoyancy, meditation or prayer. These may be extremely vivid or intense experiences, or these relatively accentuated experiences may filter into an ongoing felt transcendent connection or daily way of being connected to something more.


Sometimes it is difficult to think of a positive transcendent or spiritual experience “on the spot”. It may help to close your eyes and try to imagine yourself in the situation. While you are imagining the situation, try to generate the same sensations and feelings you would experience if you were actually in the situation. Describe the situation as though you are helping me see it as if I was there with you. (Please include such details as who was there; what you were doing; where you were; how things looked; what bodily sensations you experienced.)”

The present study showed reduced activity in the left IPL following spiritual cues, which is consistent with several previous investigations suggesting an inverse relationship between spiritual awareness and parietal activity. The posterior parietal cortex has been implicated in religiosity and spirituality across a wide variety of measures including importance of religion and spirituality (Miller et al. 2014), trait self-transcendence (Urgesi et al. 2010), implicit religiousness and spirituality (Crescentini et al. 2014, 2015), mindfulness meditation training (Lazar et al. 2000; Farb et al. 2007), and contemplative prayer (Newberg et al. 2003, 2015). Furthermore, activity in this region has been linked to spatiotemporal perceptual processes and, in particular, the representation of the human body in time and space (Assmus et al. 2003; Lou et al. 2004; Bolger et al. 2014). Since spiritual practices and experiences typically involve a perceived alteration in time and space (Newberg and Waldman 2009; Yaden et al. 2017), often an expanded sense of self in relation to the environment including subjective reports from the current study (see Supplementary Material), these findings lend support to our hypotheses and the relatively blunted activity of the IPL observed in the present study. The hemispheric lateralization of posterior parietal activation differs, however, across various studies of spirituality, which invites a more nuanced interpretation. Research has implicated the right IPL in the cognitive representation of one’s own body in space, while the left IPL has been linked to the visuo-spatial representation of others (Felician et al. 2003; Lou et al. 2004; Muhlau et al. 2005). Functionally connected to the ventral premotor cortex, the IPL contains both motor and mirror neurons which allow an observer to perceive individuals’ motor behaviors and intentions, and the left IPL in particular has been implicated in reading others’ intentions (Fogassi et al. 2005; D’Argembeau et al. 2008; Bonini et al. 2010). Moreover, research has linked the IPL to the attribution of agency, whereby left IPL activity may signal an attribution of agency outside of oneself (Farrer and Frith 2002). Taken together, the present finding suggests that spiritual experiences may involve a perceived encounter with a spacious “presence” or entity external to oneself. This interpretation is consistent with a strong feeling of connection or surrender to a deity or other revered figure, as often reported in religious and spiritual literature (James 1902; Wilber 2006).

The IPL has also been implicated in episodic memory retrieval as well as processing human faces (Leube et al. 2003; Mayes et al. 2004; Wagner et al. 2005), possibly suggesting that spiritual experiences interact with memory retrieval processes in a unique way. This possibility, however, is tempered by the fact that all three conditions involved re-experiencing highly salient memories, including those that may involve recollection of people (and thus their faces). As such, the experimental design argues against these possibilities. Nonetheless, future investigations involving larger samples may permit investigation of scripts with and without specific features (e.g., recollection of people or spiritual beings) to investigate such possibilities directly. Additionally, it is worth noting that the responses during the spiritual cue condition are congruent with the notion that systemsbased changes may occur on neural levels in response to changes in perception (Freiwald et al. 2016; Mazzarella et al. 2013).

But with mobile phones, texting, and social media, cocaine users around the world reported that their most recent cocaine order was delivered in less time, on average, than their most recent pizza order

A primer on fentanyl(s). Mark Kleiman, May 24, 2018. www.samefacts.com/2018/05/drug-policy/a-primer-on-fentanyls/

The synthetic opioids – usually referred to both in the press and by law enforcement as “fentanyl” – have now outstripped not only the prescription opioids such as oxycodone but also heroin in terms of overdose deaths, and (as you can see below) the trend line is almost vertical.

[...]

But with mobile phones, texting, and social media, transactions can now be arranged electronically and completed by home delivery, reducing the buyer’s risk and travel time to near zero and even his waiting time to minimal levels. In the recent Global Survey on Drugs, cocaine users around the world reported that their most recent cocaine order was delivered in less time, on average, than their most recent pizza order.

We predicted that skeptics would have less favorable attitudes toward celebrities in general and feel less strongly attached to their own favorite celebrity, as compared to the believers; the first prediction was confirmed but not the second

Do Religious Skeptics Differ from Religious Believers in their Interest in Celebrities? Lynn E. McCutcheon and Harvey Richman. Implicit Religion, doi:10.1558/imre.29534. Keywords: religious, skeptics, celebrities, believers, stereotypes

Given the prejudice directed toward religious skeptics, it is imperative that we learn as much as we can about this minority group. We administered the Celebrity Attitude Scale (CAS), and some brief additional measures of attitudes about celebrities to a sample of 91 religious believers and 92 skeptics recruited throughout the US from Mechanical Turk. We predicted that skeptics would have less favorable attitudes toward celebrities in general and feel less strongly attached to their own favorite celebrity, as compared to the believers. The first prediction was confirmed but not the second. We also compared believers with skeptics on choices of an “entertainer” vs. “non-entertainer” favorite celebrity, and found no significant difference. The results are discussed in light of current research on religious skeptics and celebrity worshipers.

Republicans and Democrats are equally likely to follow sports closely. However, sports fandom is positively associated with individualistic attributions for economic success and support for the US military

Sports Fandom and Political Attitudes. Emily A Thorson Michael Serazio. Public Opinion Quarterly, nfy018, https://doi.org/10.1093/poq/nfy018

Abstract: A majority of Americans identify as sports fans, and sports broadcasts attract substantially larger audiences than news on both broadcast and cable television. But despite the outsize role of sports in American life, we know little about how—or whether—sports fandom is related to political attitudes. This paper draws on a representative survey to examine (1) the association between sports fandom and political opinions; and (2) opposition to the “politicization” of sports. Republicans and Democrats are equally likely to follow sports closely. However, sports fandom is positively associated with individualistic attributions for economic success and support for the US military. In addition, conservatives are more likely to resist the intrusion of partisan politics into sports.

The Cost of Being Sexy: The long quest to understand male sexual traits, testosterone, and immunocompetence

The long quest to understand male sexual traits, testosterone, and immunocompetence

Cape ground squirrels have captured Jane Waterman's fascination for the last 30 years. “They’re so cool,” effuses Waterman. Studying them in South Africa, where these beguiling, furry mammals breed year round, she has revealed a treasure trove of surprises. Extremely social, females live in family groups with their young. Males disperse from their family group at about 3 years old, joining bachelor groups. In these all-male groups, males sleep together, groom one another, and move together through the veld. Males have no dominance hierarchy and defend no territories, and it is rare to see any sort of aggressive behavior, explains Waterman. But on the day when a female enters estrus, which lasts about 3 hours, an average of 11 males show up to try to breed. Winners in this mating game are typically older, in better body condition, and “well endowed” with big testes and more sperm, she says. Big testes, theory holds, are usually supported with an abundance of testosterone. But Waterman has not found their testosterone levels higher than those in a lot of other less-endowed species.

This intrigued her. It seemed to Waterman that to support big testes, males had to be able to keep testosterone going year round. In these squirrels, she also found more ectoparasites on males than on females—not only when males are wide-ranging adults but also when they are homebody juveniles. Her hunch was that an influx of testosterone drives a reduced male ability to fend off ectoparasites, espousing an idea known as the immunocompetence handicap hypothesis (ICHH). It is a hypothesis that she, with a graduate student, has recently tested experimentally.

Waterman's test of the ICHH follows on the heels of hundreds of studies since the idea was first articulated in The American Naturalist by Ivar Folstad and Andrew Karter in 1992. The ICHH proposes that elaborate male ornaments or signs of vigor are mediated at least in part by testosterone but that testosterone is costly in terms of compromising immune function. The ICHH is an influential hypothesis tracing its lineage back to Darwin's first musings about the tail of the peacock, the antlers of deer, and other exaggerated male traits that could attract the attention of females but might be costly for survival. For scientists who had long thought about sexual selection from a theoretical standpoint, here was a potential mechanism to explain it. The duality of testosterone—sexy but costly—suggested authors Folstad and Karter, provides a cue to choosy females as to which males cope with this burden best.

There is a clear pattern of mobile phones being carried in people’s hands, without the person using it (that is, not looking at it); In addition, when individuals join members of the opposite sex there is a clear tendency to stop holding mobile phones whilst walking

The phone walkers: a study of human dependence on inactive mobile devices. Laura P. Schaposnik and James Unwin. Behaviour, DOI: 10.1163/1568539X-00003496

Abstract: The development of mobile phones has largely increased human interactions. Whilst the use of these devices for communication has received significant attention, there has been little analysis of more passive interactions. Through census data on casual social groups, this work suggests a clear pattern of mobile phones being carried in people’s hands, without the person using it (that is, not looking at it). Moreover, this study suggests that when individuals join members of the opposite sex there is a clear tendency to stop holding mobile phones whilst walking. Although it is not clear why people hold their phones whilst walking in such large proportions (38% of solitary women, and 31% of solitary men), we highlight several possible explanation for holding the device, including the need to advertise status and affluence, to maintain immediate connection with friends and family, and to mitigate feelings related to anxiety and security.

Ingestion of glucose leads to decreased activity & connectivity in brain areas & networks linked to energy seeking and satiation; in contrast, drinking plain water leads to increased connectivity probably associated with continued food seeking & unfulfilled reward

Brain activity and connectivity changes in response to glucose ingestion. A. M. van Opstal et al. Nutritional Neuroscience, https://doi.org/10.1080/1028415X.2018.1477538

Abstract

Objectives: The regulatory role of the brain in directing eating behavior becomes increasingly recognized. Although many areas in the brain have been found to respond to food cues, very little data is available after actual caloric intake. The aim of this study was to determine normal whole brain functional responses to ingestion of glucose after an overnight fast.

Methods: Twenty-five normal weight, adult males underwent functional MRI on two separate visits. In a single-blind randomized study setup, participants received either glucose solution (50 g/300 ml of water) or plain water. We studied changes in Blood Oxygen Level Dependent (BOLD) signal, voxel-based connectivity by Eigenvector Centrality Mapping, and functional network connectivity.

Results: Ingestion of glucose led to increased centrality in the thalamus and to decreases in BOLD signal in various brain areas. Decreases in connectivity in the sensory-motor and dorsal visual stream networks were found. Ingestion of water resulted in increased centrality across the brain, and increases in connectivity in the medial and lateral visual cortex network. Increased BOLD intensity was found in the intracalcarine and cingulate cortex.

Discussion: Our data show that ingestion of glucose leads to decreased activity and connectivity in brain areas and networks linked to energy seeking and satiation. In contrast, drinking plain water leads to increased connectivity probably associated with continued food seeking and unfulfilled reward.

Girls score higher than boys in mathematics and science achievement across non-OECD nations. An association was found between gender differences in science achievement and national levels of gender equality (support for the gender segregation hypothesis)

Investigating Gender Differences in Mathematics and Science: Results from the 2011 Trends in Mathematics and Science Survey. David Reilly, David L. Neumann, Glenda Andrews. Research in Science Education, https://link.springer.com/article/10.1007/s11165-017-9630-6

Abstract: The underrepresentation of women in science, technology, engineering, and mathematics (STEM)-related fields remains a concern for educators and the scientific community. Gender differences in mathematics and science achievement play a role, in conjunction with attitudes and self-efficacy beliefs. We report results from the 2011 Trends in Mathematics and Science Study (TIMSS), a large international assessment of eighth grade students’ achievement, attitudes, and beliefs among 45 participating nations (N = 261,738). Small- to medium-sized gender differences were found for most individual nations (from d = −.60 to +.31 in mathematics achievement, and d = −.60 to +.26 for science achievement), although the direction varied and there were no global gender differences overall. Such a pattern cross-culturally is incompatible with the notion of immutable gender differences. Additionally, there were different patterns between OECD and non-OECD nations, with girls scoring higher than boys in mathematics and science achievement across non-OECD nations. An association was found between gender differences in science achievement and national levels of gender equality, providing support for the gender segregation hypothesis. Furthermore, the performance of boys was more variable than that of girls in most nations, consistent with the greater male variability hypothesis. Boys reported more favorable attitudes towards mathematics and science, and girls reported lower self-efficacy beliefs. While the gender gap in STEM achievement may be closing, there are still large sections of the world where differences remain.

Those experiencing distrust (vs. trust) endorsed more lenient moral standards for themselves than for others: Individuals who distrust and fear to be exploited show self-serving, and hence untrustworthy, moral cognition themselves

Two-Faced Morality: Distrust Promotes Divergent Moral Standards for the Self Versus Others. Alexa Weiss, Pascal Burgmer, Thomas Mussweiler. Personality and Social Psychology Bulletin,  https://doi.org/10.1177/0146167218775693

Abstract: People do not trust hypocrites, because they preach water, but drink wine. The current research shows that, ironically, when we distrust, we become moral hypocrites ourselves. We argue that experiencing distrust alerts us to the possibility that others may intent to exploit us, and that such looming exploitation differentially affects moral standards for the self versus others. Four studies (N = 1,225) examined this possibility and its underlying motivational dynamic. Study 1 established a relationship between dispositional distrust and flexible, self-serving moral cognition. In Studies 2 and 3, participants experiencing distrust (vs. trust) endorsed more lenient moral standards for themselves than for others. Study 4 explored the role of the motivation to avoid exploitation in these effects. Specifically, participants’ dispositional victim sensitivity moderated the effect of distrust on hypocrisy. Together, these findings suggest that individuals who distrust and fear to be exploited show self-serving, and hence untrustworthy, moral cognition themselves.

State mindfulness impaired motivation to complete cognitive and performance tasks, had no overall effect (good or bad) for performance; weakened future focus and arousal serially mediated demotivating effect, but also enabled people to detach from stressors, which improved task focus

Mindfulness Meditation Impairs Task Motivation but Not Performance. Andrew C. Hafenbrack, Kathleen D. Vohs. Organizational Behavior and Human Decision Processes, Volume 147, July 2018, Pages 1–15. https://doi.org/10.1016/j.obhdp.2018.05.001

Highlights
•    State mindfulness impaired motivation to complete cognitive and performance tasks.
•    State mindfulness had no overall effect (good or bad) for performance on same tasks.
•    Weakened future focus and arousal serially mediated demotivating effect.
•    Mindfulness enabled people to detach from stressors, which improved task focus.
•    Detachment and task focus help explain why mindfulness does not alter performance.

Abstract: A state of mindfulness is characterized by focused, nonjudgmental awareness of the present moment. The current research experimentally investigated how state mindfulness influences task motivation and performance, using multiple meditation inductions, comparison conditions, tasks, and participant samples. Mindfulness inductions, relative to comparison conditions, reduced motivation to tackle mundane tasks (Experiments 1–4) and pleasant tasks (Experiment 2). Decreased future focus and decreased arousal serially mediated the demotivating effect of mindfulness (Experiments 3 and 4). In contrast to changes in motivation, inducing a state of mindfulness did not affect task performance, as seen in all experiments but one (Experiments 2–5). Meta-analyses of performance experiments, including unreported findings (i.e., the file drawer), supported these conclusions. Experiment 5’s serial mediation showed that mindfulness enabled people to detach from stressors, which improved task focus. When combined with mindfulness’s demotivating effects, these results help explain why mindfulness does not alter performance.

A brief lesson that includes the assumptions of self-interest and strategic considerations moves behavior toward traditional economic rationality in ultimatum game, dictator game, and prisoner's dilemma

The Rapid Evolution of Homo Economicus: Brief Exposure to Neoclassical Assumptions Increases Self-Interested Behavior. John Ifcher, Homa Zarghamee. Journal of Behavioral and Experimental Economics, https://doi.org/10.1016/j.socec.2018.04.012

Highlights
•    Laboratory experiment using within & across-subject design
•    Identify impact of econ lessons on behavior in games used to measure selfishness
•    Econ lessons include assumption of self-interest and strategic considerations
•    Behav moves toward self-interest in ultimatum & dictator games & prisoner's dilemma
•    No effect in public-goods games

Abstract: Economics students have been shown to exhibit more selfishness than other students. Because the literature identifies the impact of long-term exposure to economics instruction (e.g., taking a course), it cannot isolate the specific course content responsible; nor can selection, peer effects, or other confounds be properly controlled for. In a laboratory experiment, we use a within- and across-subject design to identify the impact of brief, randomly-assigned economics lessons on behavior in the ultimatum game (UG), dictator game (DG), prisoner's dilemma (PD), and public-goods game (PGG). We find that a brief lesson that includes the assumptions of self-interest and strategic considerations moves behavior toward traditional economic rationality in UG, PD, and DG. Despite entering the study with higher levels of selfishness than others, subjects with prior exposure to economics instruction have similar training effects. We show that the lesson reduces efficiency and increases inequity in the UG. The results demonstrate that even brief exposure to commonplace neoclassical economics assumptions measurably moves behavior toward self-interest.

Evidence of a Flynn Effect in Children's Human Figure Drawings (1902–1968)

Evidence of a Flynn Effect in Children's Human Figure Drawings (1902–1968). Jeremy E. C. Genovese. The Journal of Genetic Psychology, https://doi.org/10.1080/00221325.2018.1469113

ABSTRACT: The Flynn effect is the long-term trend for scores on tests of cognitive ability to increase across cohorts. Several samples of children's human figure drawings, published in 1902, 1926, 1963, and 1968, are examined for evidence of a Flynn effect. Results show that larger percentages of children draw more complete human figures over the course of the 20th century.

Stone-age strategies, space-age media & signaling in profile photos: Males emphasized social status, ambition & access to material resources, females physical appearance & youthfulness. Perception of masculinity was tied to display of resources & physical strength, femininity to physical appearance & flirtatious behavior

Stone-age strategies and space-age media: Sex differences in sexual signaling on Facebook. Igor Miklousic, Mia Karabegović, Lukrecija Puljić. Periodicum Biologorum,  Vol 119 No 4 (2017). DOI: https://doi.org/10.18054/pb.v119i4.5787

Abstract: Building on the proposition of the Sexual Strategies Theory that sex differences in mating strategies and intrasexual competition will be reflected in sexual signaling behavior towards possible mates, we sought to examine if such strategies would be observable on social networking sites.

For the purpose of the study, ten male and ten female public profile pictures were randomly selected from a large pool of users (N = 1386) who chose to participate in the study and subscribed to a Facebook page created in order to aggregate users with an interest in Evolutionary psychology. Selected profile photos were then included in an online evaluation protocol, filled out by 31 independent raters, resulting in a total of 620 ratings. The protocol addressed nine evolutionarily relevant partner choice characteristics; 1) physical strength or athleticism, (2) access to resources or material possessions, (3) ambition or industriousness, (4) social status, (5) intelligence, (6) features of physical appearance, (7) features accentuating youthfulness, (8) high activity level, and (9) flirtatious behavior.

Males more frequently emphasized cues of social status, ambition and access to material resources, whereas females tended to emphasize features of physical appearance and of youthfulness. Furthermore, the perception of masculinity was mostly tied to the display of resources and physical strength, as was femininity to physical appearance and flirtatious behavior.

The Sexual Strategies Theory predictions of mating display behaviors were confirmed in online settings, demonstrating the robustness of sex differences in mating-related behaviors.

Temptation & self-selection into an opportunistic environment on an individual’s likelihood of engaging in dishonest behavior: people who tempt themselves to cheat are more likely to cheat & in greater magnitude. Self-reported value of ethics predicts honest behavior only for subjects who consider their moral principles to be “very important” in their everyday lives

Temptation and Cheating Behavior: Experimental Evidence. Jennifer Pate. Journal of Economic Psychology, https://doi.org/10.1016/j.joep.2018.05.006

Highlights
•    This study features an experiment testing the impact of temptation and self-selection into an opportunistic environment on an individual’s likelihood of engaging in dishonest behavior.
•    The empirical evidence demonstrates that people who tempt themselves to cheat are more likely to cheat.
•    Further, people who self-select into the opportunistic setting cheat to a greater magnitude than individuals placed into the same opportunistic condition by random assignment.
•    There are no gender differences in self-selection into the opportunistic environment or in overall likelihood of cheating.
•    An individual’s self-reported value of ethics predicts honest behavior but only for subjects who consider their moral principles to be “very important” in their everyday lives.

Abstract: This article presents an experiment designed to test the impact of temptation and self-selection into an opportunistic environment on an individual’s likelihood of engaging in dishonest behavior. In doing so, this experiment is the first of its kind to isolate the relationship between temptation and cheating as its primary focus, to create a randomized control group for comparative purposes, and to be conducted without deceiving subjects. The evidence shows that people who tempt themselves to cheat are more likely to cheat. Further, people who self-select into the opportunistic setting cheat to a greater extent than individuals placed into the same opportunistic condition by random assignment. There are no gender differences in choice of environment or likelihood of cheating. An individual’s self-reported value of ethics predicts honest behavior but only for subjects who consider their moral principles to be “very important” in their everyday lives. The results have direct implications for any environment where individuals can self-select into an opportunistic setting.

For men, psychopathy was a negative predictor, and narcissism a positive predictor of lifetime offspring; for women, psychopathy emerged as a negative predictor of lifetime offspring

Lifetime offspring and the Dark Triad. Gregory L. Carter, Minna Lyons, Gayle Brewer. Personality and Individual Differences, Volume 132, 1 October 2018, Pages 79–83. https://doi.org/10.1016/j.paid.2018.05.017

Abstract: There is a paucity of literature investigating the extent to which human personality predicts lifetime (age-controlled) offspring. The present study contributes to this field in assessing whether the inter-related ‘dark’ personalities that have been linked to mating success (i.e., narcissism, Machiavellianism, and psychopathy: the ‘Dark Triad’) predict number of children. Analyses from an online sample (N = 314) revealed that for men, psychopathy was a negative predictor, and narcissism a positive predictor of lifetime offspring. For women, psychopathy emerged as a negative predictor of lifetime offspring. Results are discussed in respect of the importance of these traits to fitness-related outcomes, including reproduction, and the need to consider sex differences, as these traits may have a different function in men and women.

Low (high) skill subjects are more (less) willing to take risks on gambles where the probabilities depend on relative skill. This suggests that the wrong people may engage in risky activities, such as entering competitive markets or career paths, while the right people may be crowded out

How do beliefs about skill affect risky decisions? Adrian Bruhin, Luís Santos-Pinto, David Staubli. Journal of Economic Behavior & Organization, Volume 150, June 2018, Pages 350-371. https://doi.org/10.1016/j.jebo.2018.01.016

Highlights
•    In this paper, we use a laboratory experiment to study the causal effect of beliefs about skill on risky choices.
•    The paper offers an innovative experimental test that is free of strategic confounds and based on revealed preference.
•    Low (high) skill subjects are more (less) willing to take risks on gambles where the probabilities depend on relative skill.
•    This suggests that the wrong people may engage in risky activities V such as entering competitive markets or career paths V while the right people may be crowded out.
•    Revealed beliefs are only moderately correlated with stated beliefs and so relying only on stated beliefs may be misleading.

Abstract: Beliefs about relative skill matter for risky decisions such as market entry, career choices, and financial investments. Yet in most laboratory experiments risk is exogenously given and beliefs about relative skill play no role. We use a laboratory experiment without strategy confounds to isolate the impact of beliefs about relative skill on risky choices. We find that low (high) skill individuals are more (less) willing to take risks on gambles where the probabilities depend on relative skill than on gambles with exogenously given probabilities. This happens because low (high) skill individuals overestimate (underestimate) their relative skill. Consequently, the wrong people may engage in risky activities where performance is based on relative skill while the right people may be crowded out.

We look at more information, pay more for information, look at different information when choosing for others; those who choose for others focus more on choice-alternatives, and when choosing for themselves focus more on choice-attributes

Choosing for others and its relation to information search, Yi Liu et al. Organizational Behavior and Human Decision Processes, Volume 147, July 2018, Pages 65–75. https://doi.org/10.1016/j.obhdp.2018.05.005

Highlights
•    We show that people look at more information when choosing for others.
•    We show that people will pay more for information when choosing for others.
•    We show that people will look at different information when choosing for others.
•    People who choose for others focus more on choice-alternatives.
•    People who choose for themselves focus more on choice-attributes.

Abstract: When people make choices, they both identify their options and research the unique details that comprise their options. Respectively, these two search behaviors are called alternative- and attribute-search. The literature treats these separate information search behaviors as a trade-off: Choosing to examine extant alternatives (alternative-search) means suffering the costs of not analyzing the details of alternatives (attribute-search), and vice versa. Here, we found that in choices people make for others, they search for more alternatives and more attributes than in choices people make for themselves. Moreover, we found that when people face a trade-off between searching for alternatives and attributes, people choosing for others will favor alternatives, whereas people choosing for themselves will favor attributes. Thus, we found that the pursuit of information is different when people choose for others (vs. themselves), suggesting a novel pivot to a range of areas in decision making where the alternative-attribute trade-off is ubiquitous.

Knowing about others’ political views interferes with the ability to learn about their competency in unrelated tasks, leading to suboptimal information-seeking decisions and errors in judgement

Marks, Joseph and Copland, Eloise and Loh, Eleanor and Sunstein, Cass R. and Sharot, Tali, Epistemic Spillovers: Learning Others’ Political Views Reduces the Ability to Assess and Use Their Expertise in Nonpolitical Domains (April 13, 2018). http://dx.doi.org/10.2139/ssrn.3162009

Abstract: On political questions, many people are especially likely to consult and learn from those whose political views are similar to their own, thus creating a risk of echo chambers or information cocoons. Here, we test whether the tendency to prefer knowledge from the politically like-minded generalizes to domains that have nothing to do with politics, even when evidence indicates that person is less skilled in that domain than someone with dissimilar political views. Participants had multiple opportunities to learn about others’ (1) political opinions and (2) ability to categorize geometric shapes. They then decided to whom to turn for advice when solving an incentivized shape categorization task. We find that participants falsely concluded that politically like-minded others were better at categorizing shapes and thus chose to hear from them. Participants were also more influenced by politically like-minded others, even when they had good reason not to be. The results demonstrate that knowing about others’ political views interferes with the ability to learn about their competency in unrelated tasks, leading to suboptimal information-seeking decisions and errors in judgement. Our findings have implications for political polarization and social learning in the midst of political divisions.

Experiential or Material Purchases? Social Class Determines Purchase Happiness. Individuals of higher social class, whose abundant resources make it possible to focus on self-development and self-expression, were made happier by experiential over material purchase

Experiential or Material Purchases? Social Class Determines Purchase Happiness. Jacob C. Lee, Deborah L. Hall, Wendy Wood. Psychological Science, https://doi.org/10.1177/0956797617736386

Abstract: Which should people buy to make themselves happy: experiences or material goods? The answer depends in part on the level of resources already available in their lives. Across multiple studies using a range of methodologies, we found that individuals of higher social class, whose abundant resources make it possible to focus on self-development and self-expression, were made happier by experiential over material purchases. No such experiential advantage emerged for individuals of lower social class, whose lesser resources engender concern with resource management and wise use of limited finances. Instead, lower-class individuals were made happier from material purchases or were equally happy from experiential and material purchases.

Before the 2016 election, Republicans showed greater in-group favoritism than Democrats, who treated others equally, regardless of their political affiliation; after, Republicans no longer showed in-group favoritism, while Democrats showed out-group derogation

When the tables are turned: The effects of the 2016 U.S. Presidential election on in-group favoritism and out-group hostility. Burak Oc, Celia Moore, Michael R. Bashshur. PLOS, May 24, 2018, https://doi.org/10.1371/journal.pone.0197848

Abstract: The outcome of the 2016 U.S. Presidential election was a big surprise to many, as the majority of polls had predicted the opposite outcome. In this two-stage cross-sectional study, we focus on how Democrats and Republicans reacted to this electoral surprise and how these reactions might have influenced the way they allocated resources to each other in small groups. We find that, before the election, Republicans showed greater in-group favoritism than Democrats, who treated others equally, regardless of their political affiliation. We then show that Democrats experienced the election outcome as an ego shock and, in the week following the election, reported significantly higher levels of negative emotions and lower levels of self-esteem than Republicans. These reactions then predicted how individuals’ decided to allocate resources to others: after the election, Republicans no longer showed in-group favoritism, while Democrats showed out-group derogation. We find these decisions when the tables were turned can be partially explained by differences in participants’ state self-esteem.

Mercy Sex: How Much Is “Normal” Depends Upon The Country Where You Live

Mercy Sex: How Much Is “Normal” Depends Upon Where You Live. R. Pollycove, J. Simon. The Journal of Sexual Medicine, Volume 15, Issue 6, Supplement 2, June 2018, Pages S113. https://doi.org/10.1016/j.jsxm.2018.03.052

Objective: Women engage in sexual relations despite the absence of personal sexual interest. Such sexual activity has been termed: duty sex, obligatory sex, mercy sex, etc. Medical treatments (testosterone [Intrinsa®; Libigel®], flibanserin [Addyi®], bremelanotide [RekyndaTM], lasofoxifene [Fablyn®)]) for hypoactive sexual desire disorder (HSDD; DSM-IV-TR) have investigated thousands of women. Women enrolled in HSDD trials continue to have sexual relations with their partners despite their absence of desire. We have previously reported that the “normal” frequency of sexual activity (without interest), aka “mercy sex” in these trials (a worldwide convenience sample) is 2.57 times/28 days. (n 4483). Here we examine the differences in “mercy sex” frequency among 13 European countries  to assess the impact, if any, of geographical and cultural diversity.

Materials and Methods: We analyzed baseline sexual activity data from the Orchid Trial (511.77; NCT00491829), a 24 week, randomized, doubleblind, placebo controlled, trial of flibanserin in premenopausal European women with HSDD conducted between June 2007 and March 2009 at 86 clinical trial sites in 13 European countries. All subjects used contraception. The baseline frequency of sexual activity without interest, aka “mercy sex” in these trial participants was compared by country with the norms established above.

Results: The mean number of sexual events per 28 days in the Orchid trial was: AUS 2.66, BEL 2.57, CZE 4.19, DEU 1.72, ESP 3.80, FIN 2.42, FRA 2.31, GBR 1.76, HUN 1.78, ITA 1.12, NLD 2.42; NOR 2.28, SWE 2.32.

Conclusion: Monogamous, heterosexual couples engage in sexual activity 2.57 times/28 days (n 4483) even when the female partner has HSDD. Such “mercy sex” is remarkably consistent in frequency. In certain Orchid trial countries, the frequency of “mercy sex” was inconsistent with these “norms.” These outlier results, both greater than the “norm” CZE 4.19, and ESP 3.80 events/28d; and less than the “norm” DEU 1.72, GBR 1.76, HUN 1.78, ITA 1.12, suggest significant cultural and/or social differences between countries, and provide a rich opportunity for hypothesis development and testing as to why such differences exist?

Power motivates heightened sexual attraction to the opposite sex among heterosexual men and women

Power motivates heightened sexual attraction to the opposite sex among heterosexual men and women. Lijun Zheng, Jing Zhang, Yong Zheng. Asian Journal of Social Psychology, https://doi.org/10.1111/ajsp.12324

Abstract: Previous studies have demonstrated that power induces sexual overperception by activating mating motivation. This study examined the impact of power on sexual attraction to the opposite sex among heterosexual men and women. We manipulated power by instructing participants to recall an incident in their lives where they possessed power over someone else (high power) or someone else possessed power over them (low power). We controlled for individual variations in sex drive, sexual sensation seeking, and sociosexual orientation. We asked participants to record their sexual attraction to images of the opposite sex in swimsuits. Our results showed that high‐power individuals, both men and women, recorded significantly greater sexual attraction to the images than did low‐power individuals, demonstrating that power heightens sexual attraction to the opposite sex among heterosexual men and women. The findings highlight power's activation of the mating motivation and have implications for the effect of power on sexualized behaviors.

How banking regulation has grown out of all proportions: Basel regulatory framework have now more than two million words

How banking regulation has grown out of all proportions. Marie-José Kolly and Jürg Müller. The End of Banking, May 22 2018. https://www.endofbanking.org/2018/05/22/how-banking-regulation-has-grown-out-of-all-proportions

Over the last forty years, banking regulation has grown extensively. The framework developed by the Basel Committee on Banking Supervision alone consists of two million words. What is actually stated in all these documents?

A bank fails, and politicians save it with taxpayers’ money. This story repeats itself all around the world, most recently in Russia and Italy. To prevent such costly bailouts, banking regulation has been devised and implemented for a long time. The documents of the Basel Committee on Banking Supervision play a key role for national rules.

The Neue Zürcher Zeitung (NZZ) analyzed these regulatory documents in detail. Its data team included all 163 regulatory documents with final status as of 31st of July 2017 in their analysis (see «Methods» part at the end of this article). Major elements of this regulatory framework are Basel I (the first Basel capital accord, 1988), Basel II (2005), and Basel III (2010).

The most obvious development is the sheer growth of text over the years. Figure 1 shows, for the past 40 years, how much new text the Committee has published per year.

[...]

In the aftermath of the financial crisis, the Committee has published 2795 pages. This is more than half of the entire regulatory framework consisting of 5440 pages and 2 million words – the Basel framework has reached an epic dimension.

[...]

The Basel documents are not only thousands of pages long, they are also a hard read. An average sentence in the Basel documents consists of 25.7 words, often embedded into complex grammatical structures. In comparison, an average sentence of the British National Corpus, which is a collection of texts covering a broad range of modern British English, only consists of 21 words.

Already the second sentence of the very first document published by the Basel Committee on Banking supervision spans over 72 words.

The other hidden hand: Soviet and Cuban intelligence in Allende’s Chile. Dec 2017

The other hidden hand: Soviet and Cuban intelligence in Allende’s Chile. Kristian Gustafson & Christopher Andrew. Intelligence and National Security, Volume 33, 2018 - Issue 3, Pages 407-421, Dec 2017. https://doi.org/10.1080/02684527.2017.1407549

Abstract: The role of Soviet and Cuban covert activities in Allende’s Chile has not been given sufficient consideration. This paper outlines the significant actions that the KGB and the Cuban DGI undertook there, showing that both organizations played important roles in both operating directly against the CIA and by supporting local actors. The results of their efforts, however, may have been negative to Allende’s coalition by focusing on factional or ideological interests. A broad array of sources is brought together to shed light on this historical gap. The result is a new paradigm in which we can consider this dramatic period.

Jan 2018: Guidance on Uncertainty Analysis in Scientific Assessments. EFSA Scientific Committee

Guidance on Uncertainty Analysis in Scientific Assessments. EFSA Scientific Committee. Jan 24 2018, https://doi.org/10.2903/j.efsa.2018.5123

Abstract: Uncertainty analysis is the process of identifying limitations in scientific knowledge and evaluating their implications for scientific conclusions. It is therefore relevant in all EFSA's scientific assessments and also necessary, to ensure that the assessment conclusions provide reliable information for decision‐making. The form and extent of uncertainty analysis, and how the conclusions should be reported, vary widely depending on the nature and context of each assessment and the degree of uncertainty that is present. This document provides concise guidance on how to identify which options for uncertainty analysis are appropriate in each assessment, and how to apply them. It is accompanied by a separate, supporting opinion that explains the key concepts and principles behind this Guidance, and describes the methods in more detail.

Candidate attractiveness mitigates the negative electoral effects of involvement in scandal; of all type of scandals, we also find that attractiveness has the largest moderating role if the incumbent is embroiled in a sex scandal

The Good, the Bad and the Ugly: Do Attractive Politicians Get a ‘Break’ When They are Involved in Scandals? Daniel Stockemer, Rodrigo Praino. Political Behavior, https://link.springer.com/article/10.1007/s11109-018-9469-1

Abstract: In general, politicians involved in scandals of various natures are punished by voters. Good-looking politicians, on the contrary, are rewarded by voters. Almost fifty years of empirical research has shown that ill-informed voters will use the physical attractiveness of candidates, as well as readily-available information on scandal allegations involving candidates running for office, as a heuristic shortcut to determine their voting behaviour. This article represents the first attempt to link the existing literature on the electoral effects of scandals with the existing literature of the electoral impact of candidate attractiveness. Using data on U.S. House of Representatives elections between 1972 and 2012, we find that candidate attractiveness mitigates the negative electoral effects of involvement in scandal; this implies that attractive politicians do get a “break” when involved in scandals. Of all type of scandals, we also find that candidate attractiveness has the largest moderating role if the incumbent is embroiled in a sex scandal.

Psychopathy was linked to a city/urban preference; the Dark Triad preferred living conditions with opportunities for “exploitation”

Bright lights, big city: The Dark Triad traits and geographical preferences. Peter K. Jonason. Personality and Individual Differences, Volume 132, 1 October 2018, Pages 66–73. https://doi.org/10.1016/j.paid.2018.05.024

Highlights
•    Examined living preferences and conditions associated with the Dark Triad.
•    Psychopathy, in particular, was linked to a city/urban preference.
•    The Dark Triad preferred living conditions with opportunities for “exploitation”.
•    Sex differences in featural preferences were mediated by the Dark Triad traits.

Abstract: There are many niches people can occupy and some people may fit better in certain niches than others as a function of their personality. Two simple questions were considered presently. Are people characterized by the Dark Triad traits also characterized by a bias towards living in the city and if so as they are, what features of the city-living draw them towards such geographical preferences? Study 1 (N = 753, students) assessed the correlations between population density and size and the Dark Triad traits. Study 2 (N = 270, MTurk) asked participant's where they lived and compared rates of the Dark Triad traits. Study 3 (N = 273, MTurk) assessed where people wish they lived based on location (e.g., city, suburbia) and features of that environment and related that to the Dark Triad traits. Across three studies, there was a tentative-yet-methodologically robust bias of those who are high in the Dark Triad traits—especially psychopathy—towards city life. In Study 3, sex differences in the features people want in where they live and how the Dark Triad traits correlated with the featural preferences were examined and suggested effects consistent with life history theory. Results are discussed using life history and selection-evocation-manipulation paradigms.

Children of highly ambitious parents tend to enter competition even if their chances to win are low.; parents with higher income have less ambitions regarding their children’s success in the later professional life

Parents’ Ambitions and Children’s Competitiveness. Menusch Khadjavi, Andreas Nicklisch. Journal of Economic Psychology, https://doi.org/10.1016/j.joep.2018.05.004

Highlights
•    The ambition levels of parents concerning their children’s success in the later professional life correlate with children’s competitiveness.
•    Children of highly ambitious parents tend to enter competition even if their chances to win are low.
•    Parents with higher income have less ambitions regarding their children’s success in the later professional life.

Abstract: Individual competitiveness is a personality trait of high importance. While substantial differences between individuals have been documented, the sources of this heterogeneity are not well understood. To contribute to this issue we conduct an incentivized field study with pre-school children. We assess the children’s willingness to compete and relate the inclinations to ambitions and preferences of their parents. Parents’ ambitions concerning their children’s success in professional life predict their children’s competitiveness. In particular, children of highly ambitious parents tend to enter competition even if their chances to win are low. High ambitions are related to a relatively low socioeconomic background.

Higher IQ in adolescence was associated with a number of healthier behaviours in middle age, but also with skipping meals, snacking between meals, drinking alcohol and smoking cigarettes smoked

Intelligence in youth and health behaviours in middle age. Christina Wraw, Geoff Der, Catharine R. Gale, Ian J. Deary. Intelligence, Volume 69, July–August 2018, Pages 71–86. https://doi.org/10.1016/j.intell.2018.04.005

Highlights
•    Links between intelligence in youth and mid-life health behaviours were examined.
•    Higher IQ was associated with a range of healthier behaviours in mid-life.
•    There were non-linear associations between IQ and unhealthy behaviours.
•    There was essentially no attenuation after adjusting for childhood SES.
•    Statistical significance was largely maintained after adjusting for adult SES.

Abstract

Objective: We investigated the association between intelligence in youth and a range of health-related behaviours in middle age.

Method: Participants were the 5347 men and women who responded to the National Longitudinal Survey of Youth 1979 (NLSY-79) 2012 survey. IQ was recorded with the Armed Forces Qualification Test (AFQT) when participants were aged 15 to 23 years of age. Self-reports on exercise (moderate activity, vigorous activity, and strength training), dietary, smoking, drinking, and oral health behaviours were recorded when participants were in middle age (mean age = 51.7 years). A series of regression analyses tested for an association between IQ in youth and the different health related behaviours in middle age, while adjusting for childhood socio-economic status (SES) and adult SES.

Results: Higher IQ in youth was significantly associated with the following behaviours that are beneficial to health: being more likely to be able to do moderate cardiovascular activity (Odds Ratio, 95% CI) (1.72, 1.35 to 2.20, p < .001) and strength training (1.61, 1.37 to 1.90, p < .001); being less likely to have had a sugary drink in the previous week (0.75, 0.71 to 0.80, p < .001); a lower likelihood of drinking alcohol heavily (0.67, 0.61 to 0.74, p < .001); being less likely to smoke (0.60, 0.56 to 0.65, p < .001); being more likely to floss (1.47, 1.35 to 1.59, p < .001); and being more likely to say they “often” read the nutritional information (1.20, 1.09 to 1.31, p < .001) and ingredients (1.24, 1.12 to 1.36, p < .001) on food packaging compared to always reading them. Higher IQ was also linked with dietary behaviours that may or may not be linked with poorer health outcomes (i.e. being more likely to have skipped a meal (1.10, 1.03 to 1.17, p = .005) and snacked between meals (1.37, 1.26 to 1.50, p < .001) in the previous week). An inverted u-shaped association was also found between IQ and the number of meals skipped per week. Higher IQ was also linked with behaviours that are known to be linked with poorer health (i.e. a higher likelihood of drinking alcohol compared to being abstinent from drinking alcohol (1.58, 1.47 to 1.69, p < .001)). A u-shaped association was found between IQ and the amount of alcohol consumed per week and an inverted u-shaped association was found between IQ and the number of cigarettes smoked a day. Across all outcomes, adjusting for childhood SES tended to attenuate the estimated effect size only slightly. Adjusting for adult SES led to more marked attenuation but statistical significance was maintained in most cases.

Conclusion: In the present study, a higher IQ in adolescence was associated with a number of healthier behaviours in middle age. In contrast to these results, a few associations were also identified between higher intelligence and behaviours that may or may not be linked with poor health (i.e. skipping meals and snacking between meals) and with behaviours that are known to be linked with poor health (i.e. drinking alcohol and the number of cigarettes smoked). To explore mechanisms of association, future studies could test for a range of health behaviours as potential mediators between IQ and morbidity or mortality in later life.

Rejecting Unwanted Romantic Advances Is More Difficult Than Suitors Realize

Rejecting Unwanted Romantic Advances Is More Difficult Than Suitors Realize. Vanessa K. Bohns, Lauren A. DeVincent. Social Psychological and Personality Science, https://doi.org/10.1177/1948550618769880

Abstract: In two preregistered studies, we find that initiators of unrequited romantic advances fail to appreciate the difficult position their targets occupy, both in terms of how uncomfortable it is for targets to reject an advance and how targets’ behavior is affected, professionally and otherwise, because of this discomfort. We find the same pattern of results in a survey of science, technology, engineering, and mathematics (STEM) graduate students (N = 942) who recalled actual instances of unwanted or unrequited romantic pursuit (Study 1) and in an experiment in which participants (N = 385) were randomly assigned to the roles of “target” or “suitor” when reading a vignette involving an unwanted romantic advance made by a coworker (Study 2). Notably, women in our Study 1 sample of STEM graduate students were more than twice as likely to report having been in the position of target as men; thus, our findings have potential implications for the retention of women in STEM.

There Is No Advantageous Inequity Aversion When One Is Not Responsible For The Unequal Allocation

Advantageous Inequity Aversion Does Not Always Exist: The Role of Determining Allocations Modulates Preferences for Advantageous Inequity. Ou Li, Fuming Xu4 and Lei Wang. Front. Psychol., May 23 2018, https://doi.org/10.3389/fpsyg.2018.00749

Abstract: Previous studies have shown that people would like to sacrifice benefits to themselves in order to avoid inequitable outcomes, not only when they receive less than others (disadvantageous inequity aversion) but also when they receive more (advantageous inequity aversion). This feature is captured by the theory of inequity aversion. The present study was inspired by what appears to be asymmetry in the research paradigm toward advantageous inequity aversion. Specifically, studies that supported the existence of advantageous inequity aversion always relied on the paradigm in which participants can determine allocations. Thus, it is interesting to know what would occur if participants could not determine allocations or simply passed judgment on predetermined allocations. To address this, a behavioral experiment (N = 118) and a skin conductance response (SCR) experiment (N = 29) were adopted to compare participants' preferences for advantageous inequity directly when allocations were determined and when allocations were predetermined in an allocating task. In the determined condition, participants could divide by themselves a sum of money between themselves and a matched person, whereas in the predetermined condition, they could simply indicate their satisfaction with an equivalent program-generated allocation. It was found that, compared with those in the determined condition, participants in the predetermined condition behaved as if they liked the advantageous inequity and equity to the same degree (Experiment One) and that the SCRs elicited by advantageous inequity had no differences from those elicited by equity, suggesting that participants did not feel negatively toward advantageous inequity in this situation (Experiment Two). The present study provided mutual corroboration (behavioral and electrophysiological data) to document that advantageous inequity aversion may differ as a function of the individual's role in determining allocations, and it would disappear if individual cannot determine allocations.

Meta-Analysis Suggests Choosy Females Get Sexy Sons More Than 'Good Genes'

Meta-Analysis Suggests Choosy Females Get Sexy Sons More Than 'Good Genes'. Zofia M. Prokop, Łukasz Michalczyk, Szymon M. Drobniak, Magdalena Herdegen, Jacek Radwan. Evolution, https://doi.org/10.1111/j.1558-5646.2012.01654.x

Abstract: Female preferences for specific male phenotypes have been documented across a wide range of animal taxa, including numerous species where males contribute only gametes to offspring production. Yet, selective pressures maintaining such preferences are among the major unknowns of evolutionary biology. Theoretical studies suggest that preferences can evolve if they confer genetic benefits in terms of increased attractiveness of sons (“Fisherian” models) or overall fitness of offspring (“good genes” models). These two types of models predict, respectively, that male attractiveness is heritable and genetically correlated with fitness. In this meta‐analysis, we draw general conclusions from over two decades worth of empirical studies testing these predictions (90 studies on 55 species in total). We found evidence for heritability of male attractiveness. However, attractiveness showed no association with traits directly associated with fitness (life‐history traits). Interestingly, it did show a positive correlation with physiological traits, which include immunocompetence and condition. In conclusion, our results support “Fisherian” models of preference evolution, while providing equivocal evidence for “good genes.” We pinpoint research directions that should stimulate progress in our understanding of the evolution of female choice.

Do Patients With Parkinson’s Disease Exhibit Reduced Cheating Behavior When There Are Opportunities for Dishonest Gain? It seems they do because of impairment in reward anticipation

Do Patients With Parkinson’s Disease Exhibit Reduced Cheating Behavior? A Neuropsychological Study. Nobuhito Abe et al. Front. Neurol., May 24 2018, https://doi.org/10.3389/fneur.2018.00378

Abstract: Parkinson’s disease (PD) is a common neurodegenerative disorder characterized by loss of dopamine neurons. Since a seminal report was published in the early twentieth century, a growing body of literature has suggested that patients with PD display characteristic personality traits, such as cautiousness and inflexibility. Notably, PD patients have also been described as “honest,” indicating that they have a remarkable tendency to avoid behaving dishonestly. In this study, we predicted that PD patients show reduced cheating behavior in opportunities for dishonest gain due to dysfunction of the dopaminergic reward system. Thirty-two PD patients without dementia and 20 healthy controls (HC) completed an incentivized prediction task where participants were rewarded based on their self-reported accuracy, affording them the opportunity to behave dishonestly. Compared with HC, PD patients showed significantly lower accuracy in the prediction task. Furthermore, the mean accuracy of PD patients was virtually equivalent to the chance level. These results indicate that PD patients exhibit reduced cheating behavior when confronted with opportunities for dishonest gain.

China's social credit system has blocked people from taking 11.14 million flights and 4.25 million high-speed train trips

China's social credit system has blocked people from taking 11 million flights and 4 million train trips. Tara Francis Chan. May 21, 2018.
http://www.businessinsider.com/china-social-credit-system-blocked-people-taking-flights-train-trips-2018-5

China's social credit system has blocked people from taking 11.14 million flights and 4.25 million high-speed train trips.

The numbers, from the end of April, were included in a report by China's state-run news outlet Global Times  [http://www.globaltimes.cn/content/1103262.shtml], but it is unclear what offenses those targeted in the travel ban have committed.

The social credit system is actually a collection of blacklists, of which there are more than a dozen at the national level. Each list is based on similar offenses — such as misbehavior on planes and trains, or failing to abide by a court judgment — and determines the punishments people face, from throttling internet speeds to blocking loans.

While it's not made clear which list has had so many plane and train trips blocked, a former official, Hou Yunchun, is quoted as saying the system needs to be improved so "discredited people become bankrupt."

 The blacklist Hou is referring to most likely involves debtors and was created by the Supreme People's Court in an attempt to make people comply with verdicts and repay their debts.

The court publishes the names and ID numbers of debtors on its website. They are banned from plane and high-speed train travel, and can't stay at four and five star hotels, send their children to expensive schools, book cheap hire cars, or make luxury purchases online.

Some provinces play a recorded message when someone tries to call a blacklisted debtor, informing the caller that the person they want to speak with has outstanding debts. And in May, a short cartoon with the photographs of debtors' faces began playing at movie theatres, on buses, and on public noticeboards with a voiceover that said: "Come, come, look at these [debtors]. It's a person who borrows money and doesn't pay it back."

The list of debtors launched in late 2013 with 31,259 names and within two weeks had been visited 180,000 times. By December 2017, 8.8 million debtors had been added to the list, preventing 8.7 million flights and 3.4 million high-speed train trips.

With nearly 2.5 million trips blocked in the past six months, either China has cracked down on existing debtors' plane travel or many more names have been added to the blacklist.

Are Black Robots Like Black People? Examining How Negative Stigmas about Race Are Applied to Colored Robot

Are Black Robots Like Black People? Examining How Negative Stigmas about Race Are Applied to Colored Robots. Jeannice Louine et al. Sociological Inquiry, https://doi.org/10.1111/soin.12230

Abstract: Recent scholarly research has begun to examine human perceptions toward robots. Researchers have also demonstrated that humans make decisions about individuals based on skin color. However, scant research examines the perceptions that individuals have toward robots of certain colors or whether these perceptions, both negative and positive, are predicted by demographic and contextual factors of either humans or robots. Using data from 504 adults responding to robots in separate scenarios across two surveys, we explore whether robot color has an impact on the human's perception of that robot. Respondents were presented with pictures of black, yellow, and neutral‐colored robots and were asked to indicate their perceptions of the robots along a number of dimensions or were asked to indicate how they would react to the robot were they to encounter the robots in their daily activities. Findings suggest that (1) black robots were viewed as significantly stronger than yellow robots; (2) yellow robots were viewed as significantly more affable than black and neutral robots; and (3) respondents were more likely to move away from black robots (and less likely to stop when encountering black robots) than robots of other colors. Possible explanations and implications for these findings are also discussed.

Mate preferences on actual mating decisions, on tactics of mate attraction/retention, patterns of deception, causes of sexual regret, attraction to cues to sexual exploitability, attraction to cues to fertility, attraction to cues to resources and protection, derogation of competitors, causes of breakups, & patterns of remarriage

Mate preferences and their behavioral manifestations. David M. Buss and David P. Schmitt. Brunel University, Dept of Life Sciences Research Papers, http://bura.brunel.ac.uk/handle/2438/16165

Abstract: Evolved mate preferences define a central causal process in Darwin’s theory of sexual selection. Their powerful influence has been documented in all well-studied sexually reproducing species, and is central to Sexual Strategies Theory (SST) as applied to humans. This chapter takes stock of what is scientifically known about human mate preferences and their many behavioral manifestations. We discuss sex differences and sex similarities in the design features of human sexual psychology as they vary according to short-term and long-term mating temporal contexts. We review context-specific shifts in mating strategy depending on individual, social, and ecological qualities such as mate value, life history strategy, sex ratio, gender economic inequality, and cultural norms. For mate preferences to have evolved, they must be manifested in actual mating behavior in some individuals some of the time, such as those with high mate value in contexts where freedom of mate choice is permitted. We review the empirical evidence for the impact of mate preferences on actual mating decisions, as well as on tactics of mate attraction, tactics of mate retention, patterns of deception, causes of sexual regret, attraction to cues to sexual exploitability, attraction to cues to fertility, attraction to cues to resources and protection, derogation of competitors, causes of breakups, and patterns of remarriage. We conclude by articulating unresolved issues and offer a future agenda for the science of human mating. This agenda includes resolving key debates, such as competing evolutionary hypotheses about the functions of women’s short-term mating; how humans invent novel cultural technologies to better implement ancient sexual strategies; and how cultural evolution may be dramatically influencing our evolved mating psychology.

Do women’s preferences translate into actual mating behavior? In one study of speed dating, women were more likely to actually select men who indicated that they had grown up in an affluent neighborhood (Hitch et al., 2010). Another study of 382 speed daters found that women were more likely than men to select dates who had higher levels of income and education (Asendorpf et al., 2011; see also Li & Meltzer, 2015). A study of mail-order brides from Colombia, the Philippines, and Russia found that women actively sought men with higher levels of status and ambition (Minervini & McAndrew, 2006). A study of 2,956 Israelis using a computer dating service found that women, far more than men, sought mates who owned their own cars, had good economic standing, and who placed a high level of importance on their careers (Bokek-Cohen et al., 2008). In the Kipisigis of Kenya, women and their parents preferentially select men who have large plots of land (Borgerhoff Mulder, 1990). And the men who women choose to marry, compared to same-aged men who do not marry, have consistently higher incomes (Buss, 2016).

Would women who acted on these long-term mate preferences, actually selecting men of high status and resources, have experienced greater reproductive success? There is evidence that women married to older, higher-status men have more and more surviving children (Nettle & Pollet, 2008). For instance, in a study of 1700s pre-industrial Finland, women married to wealthier men had more children and better child survival rates than women married to poorer men (Pettay et al., 2007). Fieder and Huber (2007) found marrying a man four years older was associated with maximum levels of fertility among women, which matches closely what women say is their ideal long-term mate (Buss, 1989; Kenrick & Keefe, 1992).

A cross-cultural study of the causes of divorce found that inadequate economic support, including inadequate food, housing, and clothing, was a sex-linked cause of marital dissolution (Betzig, 1989). In no society did a woman’s failure to provide economic resources constitute grounds for divorce. Women’s mate preferences for economic resources and social status in a long-term mate translate into actual mating behavior, from selective decisions in speed dating to real-life fertility outcomes to the causes of divorce. As with men’s preferences, women’s mate preferences matter in real-world mating markets.
