From 2017: Exceptionalism is not exceptional in relation to sexual and reproduction mechanisms — Contrasts of human and animal sexuality
Exceptionalism is not exceptional in relation to sexual and reproduction mechanisms: Contrasts of human and animal sexuality. Roy J. Levin. Clin. Anat. 30:940–945, 2017. https://doi.org/10.1002/ca.22960
Abstract: Speculation that the release of oxytocin by orgasm in the human female during coitus facilitates fertility by enhancing uterine sperm transport has been criticized as having no unequivocal empirical human evidence. However, a counter claim that this supports human “exceptionalism” as some form of uterine sperm transport occurs in other species. This is a misconception as it ignores that human uterine peristalsis, powered by contractions of the smooth muscle of the archimyometrium, facilitates sperm transport even without any systemic oxytocin involvement. Moreover, examination of various unique reproductive mechanisms in numerous animals also indicates that the claim is misjudged and rests on a biased interpretation of what “exceptionalism” means in this biological context. Ten chosen aspects of our sexuality are presented as being exceptional to humans.

From 2013: Sexual Wiring of Women's Breasts — Neuroscientists establish breasts as sexual organs

Neuroscientists establish breasts as sexual organs
Excerpts (full text with links in the link above):
If men have sex on the brain, they are not alone. Recent research found that women’s sensory cortex has three distinct areas corresponding to stimulation of the clitoris, vagina, and cervix (1). To their surprise, researchers found that self stimulation of the nipples lights up the same areas. This sheds further light on the sexual importance of breasts.
In an earlier post, I discussed some evolutionary reasons that men are fascinated by women’s breasts and pointed out that stimulation of the breast plays a key role in women’s sexual arousal and satisfaction.
The Background
The permanently enlarged human breast is a peculiarity of our species (2). It may have some signal value in communicating fertility and plays a role in physical attractiveness.
Breasts are less eroticized in subsistence societies where women go topless than in our own where they are exploited in advertising, and in pornography. Even in subsistence societies, breasts are not entirely lacking in sexual significance and are generally stimulated in foreplay according to ethnographic accounts (3).
Moreover, the breasts play a key role in female sexual arousal and we are beginning to understand why in terms of hormones and neuroscience. In their classic report on the female sexual response, Masters and Johnson (4) pointed out that breast volume increases during sexual arousal in addition to changes in the areola and erection of the nipples.
The breast and bonding
The function of the breast in sexual behavior is sometimes attributed to face-to-face copulation that is unusual amongst mammals. If the breast is already used for mother- infant bonding, the argument goes, then it is a small step for it to be used in facilitating bonding between lovers. After all, it is in easy reach!
Stimulation of the nipple during breast feeding increases the amount of the hormone oxytocin that circulates. Oxytocin is often referred to as the “cuddling hormone” because it is released by male and female mammals during close social encounters of various kinds (5).
In addition to its general social effects, whereby a mother feels closeness for the baby she is feeding (and vice versa), there are other more specialized functions of oxytocin. One is that milk flows, a reflex known as the “milk let-down response” familiar to mothers and dairy farmers alike.
Another is sexual arousal, and orgasm. Some women experiencing intense pleasure - even orgasm - from breast feeding. This phenomenon was long written off as a mere oddity but neuroscientists are beginning to understand why it happens.
Sexual wiring of women’s brains
The great complexity of the female sexual response may be attributable to the fact that there is not one, but three sensory maps in the parietal cortex that light up in functional MRI images when the genitals are (self) stimulated. One represents the clitoris, another the vagina and the third represents the cervix.
All three of these maps also receive input when the nipple is stimulated. From a functional perspective, this means that the breast doubles as a truly sexual organ. It is not just an exciting visual stimulus for (most) men but also a key source of sexual pleasure for most women.
As to the wiring of men’s nipples the jury is out. Some men’s nipples are also responsive to sexual stimulation but the brain response has yet to be mapped.

The mating preferences of female fruitflies are strongly influenced by the existing preferences they observe in other females, generating traditions that are repeatedly passed on to others and spread in the population
Culture and conformity shape fruitfly mating. Andrew Whiten et al. Science Vol. 362, Issue 6418, pp. 998-999. DOI: 10.1126/science.aav5674
Summary: Culture pervades every aspect of human lives, its achievements providing a compelling explanation for our species' domination of the planet (1). Defined as the matrix of traditions built by previous generations and inherited by social learning, culture was long thought to be uniquely human. In recent decades, however, mounting evidence for culture defined in this way has accumulated for numerous vertebrate species and an expanding diversity of behaviors (2). Examples include migratory knowledge in bighorn sheep (3); foraging techniques in humpback whales (4), great tits (5), and bumble bees (6); and tool use in apes (2). These discoveries suggest that although human culture has developed unprecedented complexities, it evolved from more elementary forms shared with other species. On page 1025 of this issue, Danchin et al. (7) offer evidence that a species that may surprise many should be added to this growing animal “culture club”: the humble fruitfly. They show that the mating preferences of female fruitflies are strongly influenced by the existing preferences they observe in other females, generating traditions that are repeatedly passed on to others and spread in the population. Animal culture may be a much more widespread phenomenon than hitherto acknowledged.

Vertical pupils are perceived as more threatening; snake phobia, & not spider phobia, was found to be related to perceiving vertical pupils as threatening
The evil eye effect: vertical pupils are perceived as more threatening. Sinan Alper, Elif Oyku Us & Dicle Rojda Tasman. Cognition and Emotion, https://doi.org/10.1080/02699931.2018.1550741
ABSTRACT: Popular culture has many examples of evil characters having vertically pupilled eyes. Humans have a long evolutionary history of rivalry with snakes and their visual systems were evolved to rapidly detect snakes and snake-related cues. Considering such evolutionary background, we hypothesised that humans would perceive vertical pupils, which are characteristics of ambush predators including some of the snakes, as threatening. In seven studies (aggregate N = 1458) conducted on samples from American and Turkish samples, we found that vertical pupils are perceived as more threatening on both explicit (Study 1) and implicit level (Studies 2–7) and they are associated with physical, rather than social, threat (Study 4). Findings provided partial support regarding our hypothesis about the relevance of snake detection processes: Snake phobia, and not spider phobia, was found to be related to perceiving vertical pupils as threatening (Study 5), however an experimental manipulation of saliency of snakes rendered no significant effect (Study 6) and a comparison of fears of snakes, alligators, and cats did not support our prediction (Study 7). We discuss the potential implications and limitations of these novel findings.

In matters of the heart, as in many other matters generally, we adhere to existing states (“status quo bias”) & value them more (“endowment effect”)
I Have, Therefore I Love: Status Quo Preference in Mate Choice. Gul Gunaydin et al. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167217746339
Abstract: Decades of research indicate that individuals adhere to existing states (“status quo bias”) and value them more (“endowment effect”). The present work is the first to investigate status quo preference within the context of trade-offs in mate choice. Across seven studies (total N = 1,567), participants indicated whether they would prefer remaining with a current partner possessing a particular set of traits (e.g., high trustworthiness, low attractiveness) or switching to an alternative partner possessing opposite traits. Preference for a given trait was highest when the individual representing the status quo (one’s romantic partner or an interaction partner) possessed that trait. Concerns about hurting the partner, ambiguity avoidance, and biased construal of the partner and the alternative predicted status quo preference and disapproval of the current partner by network members eliminated this effect. These findings indicate that when it comes to matters of the heart, we tend to love what we currently have.

Psychopathy and homicide are importantly linked and that psychopathic personality functioning is a significant risk factor for various forms of lethal violence
Psychopathic killers: A meta-analytic review of the psychopathy-homicide nexus. Bryanna Fox, Matt DeLisi. Aggression and Violent Behavior, https://doi.org/10.1016/j.avb.2018.11.005
Abstract: Despite cultural notions that psychopathy and homicide are strongly linked, there has not been a quantitative meta-analytic review of the association between psychopathy and homicide offending. The current study meta-analyzed data from 29 unique samples from 22 studies that included 2603 homicide offenders, and found that the mean psychopathy score on the PCL-R for a homicide offender was 21.2 (95% CI = 18.9–23.6). This score is indicative of moderate psychopathy. The overall effect size r = 0.68 was large, and effect sizes intensified in studies of more severe manifestations of homicide including sexual homicide (r = 0.71), sadistic homicide (r = 0.78), serial homicide (r = 0.74), and multi-offender homicide (r = 0.80). Current study findings make clear that psychopathy and homicide are importantly linked and that psychopathic personality functioning is a significant risk factor for various forms of lethal violence.

An oxytocin receptor gene has been associated with emotional traits such as positive affect and related constructs such as optimism and self-esteem; this seems not replicable
The Oxytocin Receptor Gene (OXTR) Variant rs53576 is Not Related to Emotional Traits or States in Young Adults. Tamlin S. Conner et al. Front. Psychol. | doi: 10.3389/fpsyg.2018.02548
Abstract
BACKGROUND: To understand the genetic underpinnings of emotion, researchers have studied genetic variants in the oxytocin system, a hormone and neurotransmitter important to socio-emotional functioning. The oxytocin receptor gene (OXTR) variant rs53576 has been associated with emotional traits such as positive affect and related constructs such as optimism and self-esteem. Individuals carrying the A allele (AG and AA genotypes) of rs53576 have been found to score lower in these traits when compared to GG homozygotes, although not always. Given recent mixed evidence regarding this polymorphism, replication of these associations is critical.
METHODS: Using a cross-sectional design, the present study tested the association between rs53576 and a wide variety of emotional traits and states in a sample of 611 young adults ages 18 - 25 of various ethnicities (European, Asian, Māori/Pacific Islander, other). Participants completed standard trait measures of positive and negative affect, depressive symptoms, life engagement, psychological well-being, optimism, and self-esteem. They also completed state measures of positive and negative affect and life engagement for 13-days using Internet daily diaries.
RESULTS: Controlling for ethnicity and gender, variation at the OXTR variant rs53576 obtained from blood samples was not related to any of the emotional traits or states. This null finding occurred despite measuring emotions in ‘near to real time’ using daily diaries and having sufficient power to detect a medium effect size difference between homozygous genotype groups.
CONCLUSION: These findings suggest that variation at the rs53576 locus may not be as involved in emotional differences as initial studies suggested.

Mindfulness not related to behavioral & speech markers of emotional positivity (or less negativity), interpersonally better connected (quality or quantity), or prosocial orientation (more affectionate, less gossipy or complaining)
Dispositional mindfulness in daily life: A naturalistic observation study. Deanna M. Kaplan, L. Raison, Anne Milek, Allison M. Tackman, Thaddeus W. W. Pace, Matthias R. Mehl. PLOS, https://doi.org/10.1371/journal.pone.0206029
Abstract: Mindfulness has seen an extraordinary rise as a scientific construct, yet surprisingly little is known about how it manifests behaviorally in daily life. The present study identifies assumptions regarding how mindfulness relates to behavior and contrasts them against actual behavioral manifestations of trait mindfulness in daily life. Study 1 (N = 427) shows that mindfulness is assumed to relate to emotional positivity, quality social interactions, prosocial orientation and attention to sensory perceptions. In Study 2, 185 participants completed a gold-standard, self-reported mindfulness measure (the FFMQ) and underwent naturalistic observation sampling to assess their daily behaviors. Trait mindfulness was robustly related to a heightened perceptual focus in conversations. However, it was not related to behavioral and speech markers of emotional positivity, quality social interactions, or prosocial orientation. These findings suggest that the subjective and self-reported experience of being mindful in daily life is expressed primarily through sharpened perceptual attention, rather than through other behavioral or social differences. This highlights the need for ecological models of how dispositional mindfulness “works” in daily life, and raises questions about the measurement of mindfulness.

Those who minimize (vs. acknowledge) the extent to which their group is the target of discrimination report better well-being across myriad indicators: body mass index, social well-being, self-esteem, depression, & mental illness diagnosis
The Palliative Effects of System Justification on the Health and Happiness of Lesbian, Gay, Bisexual, and Transgender Individuals. Alexandra Suppes, Jaime L. Napier, Jojanneke van der Toorn. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167218785156
Abstract: Across three studies, we examine the correlates of subjective well-being and mental and physical health among members of a historically disadvantaged group, namely, lesbian, gay, bisexual, and transgender (LGBT) individuals. Results show those who minimize (vs. acknowledge) the extent to which their group is the target of discrimination report better well-being across myriad indicators (Studies 1-3). We also demonstrate that this effect is mediated by perceived system fairness (Study 1); holds above and beyond internalized homonegativity (Studies 1 and 3) and ingroup identification (Studies 2-3); and is true regardless of whether individuals reside in hostile or accepting environments (Study 2), and regardless of whether individuals had personally experienced discrimination (Study 3). For some indicators (namely, body mass index [BMI], social well-being, self-esteem, depression, and mental illness diagnosis), the relationship between minimization of discrimination and well-being was stronger among those who had frequent (vs. rare) discriminatory experiences.

Border wall expansion, 2007-2010, harmed Mexican workers & high-skill U.S. workers, but benefited U.S. low-skill ones; reduced trade costs between US & Mexico by 25% should have reduced Mexico to US migration with welfare gains
Border Walls. Treb Allen, Cauê de Castro Dobbin, Melanie Morten. NBER Working Paper No. 25267, Nov 2018, https://www.nber.org/papers/w25267
What are the economic impacts of a border wall between the United States and Mexico? We use confidential data on bilateral flows of primarily unauthorized Mexican workers to the United States to estimate how a substantial expansion of the border wall between the United States and Mexico from 2007 to 2010 affected migration. We then combine these estimates with a general equilibrium spatial model featuring multiple labor types and a flexible underlying geography to quantify the economic impact of the wall expansion. At a construction cost of approximately $7 per person in the United States, we estimate that the border wall expansion harmed Mexican workers and high-skill U.S. workers, but benefited U.S. low-skill workers, who achieved gains equivalent to an increase in per capita income of $0.36. In contrast, a counterfactual policy which instead reduced trade costs between the United States and Mexico by 25% would have resulted in both greater declines in Mexico to United States migration and substantial welfare gains for all workers.

To quantify partisan audience bias, we developed a domain-level score by leveraging the sharing propensities of registered voters on a large Twitter panel; we found little evidence for the "filter bubble'' hypothesis
Auditing Partisan Audience Bias within Google Search. Ronald E. Robertson et al. Proceedings of the ACM on Human-Computer Interaction - CSCW archive. Volume 2 Issue CSCW, November 2018, Article No. 148, doi: 10.1145/3274417
Abstract: There is a growing consensus that online platforms have a systematic influence on the democratic process. However, research beyond social media is limited. In this paper, we report the results of a mixed-methods algorithm audit of partisan audience bias and personalization within Google Search. Following Donald Trump's inauguration, we recruited 187 participants to complete a survey and install a browser extension that enabled us to collect Search Engine Results Pages (SERPs) from their computers. To quantify partisan audience bias, we developed a domain-level score by leveraging the sharing propensities of registered voters on a large Twitter panel. We found little evidence for the "filter bubble'' hypothesis. Instead, we found that results positioned toward the bottom of Google SERPs were more left-leaning than results positioned toward the top, and that the direction and magnitude of overall lean varied by search query, component type (e.g. "answer boxes"), and other factors. Utilizing rank-weighted metrics that we adapted from prior work, we also found that Google's rankings shifted the average lean of SERPs to the right of their unweighted average.

Abstract: There is a growing consensus that online platforms have a systematic influence on the democratic process. However, research beyond social media is limited. In this paper, we report the results of a mixed-methods algorithm audit of partisan audience bias and personalization within Google Search. Following Donald Trump's inauguration, we recruited 187 participants to complete a survey and install a browser extension that enabled us to collect Search Engine Results Pages (SERPs) from their computers. To quantify partisan audience bias, we developed a domain-level score by leveraging the sharing propensities of registered voters on a large Twitter panel. We found little evidence for the "filter bubble'' hypothesis. Instead, we found that results positioned toward the bottom of Google SERPs were more left-leaning than results positioned toward the top, and that the direction and magnitude of overall lean varied by search query, component type (e.g. "answer boxes"), and other factors. Utilizing rank-weighted metrics that we adapted from prior work, we also found that Google's rankings shifted the average lean of SERPs to the right of their unweighted average.

Young adult mental health and functional outcomes among individuals with remitted, persistent and late-onset ADHD
Agnew-Blais, J., Polanczyk, G., Danese, A., Wertz, J., Moffitt, T., & Arseneault, L. (2018). Young adult mental health and functional outcomes among individuals with remitted, persistent and late-onset ADHD. The British Journal of Psychiatry, 213(3), 526-534. doi:10.1192/bjp.2018.97
Abstract
Background: Attention-deficit hyperactivity disorder (ADHD) is associated with mental health problems and functional impairment across many domains. However, how the longitudinal course of ADHD affects later functioning remains unclear.
Aims: We aimed to disentangle how ADHD developmental patterns are associated with young adult functioning.
Method: The Environmental Risk (E-Risk) Longitudinal Twin Study is a population-based cohort of 2232 twins born in England and Wales in 1994–1995. We assessed ADHD in childhood at ages 5, 7, 10 and 12 years and in young adulthood at age 18 years. We examined three developmental patterns of ADHD from childhood to young adulthood – remitted, persistent and late-onset ADHD – and compared these groups with one another and with non-ADHD controls on functioning at age 18 years. We additionally tested whether group differences were attributable to childhood IQ, childhood conduct disorder or familial factors shared between twins.
Results: Compared with individuals without ADHD, those with remitted ADHD showed poorer physical health and socioeconomic outcomes in young adulthood. Individuals with persistent or late-onset ADHD showed poorer functioning across all domains, including mental health, substance misuse, psychosocial, physical health and socioeconomic outcomes. Overall, these associations were not explained by childhood IQ, childhood conduct disorder or shared familial factors.
Conclusions: Long-term associations of childhood ADHD with adverse physical health and socioeconomic outcomes underscore the need for early intervention. Young adult ADHD showed stronger associations with poorer mental health, substance misuse and psychosocial outcomes, emphasising the importance of identifying and treating adults with ADHD.

Attitudes towards robots became more negative between 2012 and 2017; robots assisting at work showed the strongest negative trend; countries with a larger share of older citizens evaluated robots more favorably
Are robots becoming unpopular? Changes in attitudes towards autonomous robotic systems in Europe. Timo Gnambs, Markus Appel. Computers in Human Behavior, https://doi.org/10.1016/j.chb.2018.11.045
Highlights
• Attitudes towards robots became more negative between 2012 and 2017.
• Attitudes towards robots assisting at work showed the strongest negative trend.
• Women with lower education evaluated robots more negatively.
• Countries with a larger share of older citizens evaluated robots more favorably.
Abstract: Many societies are on the brink of a robotic era. In the near future, various autonomous computer systems are expected to be part of many people's daily lives. Because attitudes influence the adoption of new technologies, we studied the attitudes towards robots in the European Union between 2012 and 2017. Using representative samples from 27 countries (three waves, total N = 80,396), these analyses showed that, within five years, public opinions regarding robots exhibited a marked negative trend. Respondents became more cautious towards the use of robots. This tendency was particularly strong for robots at the workplace, which are, despite the drop, still more positively evaluated than robots performing surgeries or autonomous cars. Attitudes were more positive among men and people in white-collar jobs. Moreover, countries with a larger share of older citizens evaluated robotic assistance more favorably. In general, these results highlight increasing reservations towards autonomous robotic systems in Europe.

The impact of pseudo-psychological demonstrations make people believe that one can read a person’s mind by evaluating micro expressions, psychological profiles & muscle activities, & can prime a person’s behaviour through subtle suggestions
Fake science: The impact of pseudo-psychological demonstrations on people’s beliefs in psychological principles. Yuxuan Lan, Christine Mohr, Xiaomeng Hu, Gustav Kuhn. PLOS, https://doi.org/10.1371/journal.pone.0207629
Abstract: Magicians use deception to create effects that allow us to experience the impossible. More recently, magicians have started to contextualize these tricks in psychological demonstrations. We investigated whether witnessing a magic demonstration alters people’s beliefs in these pseudo-psychological principles. In the classroom, a magician claimed to use psychological skills to read a volunteer’s thoughts. After this demonstration, participants reported higher beliefs that an individual can 1) read a person’s mind by evaluating micro expressions, psychological profiles and muscle activities, and 2) effectively prime a person’s behaviour through subtle suggestions. Whether he was presented as a magician or psychologist did not influence people’s beliefs about how the demonstration was achieved, nor did it influence their beliefs in pseudo-psychological principles. Our results demonstrate that pseudo-psychological demonstrations can have a significant impact on perpetuating false beliefs in scientific principles and raise important questions about the wider impact of scientific misinformation.

Doubling the permissible length of a Tweet led to more polite, less informal, more analytical, and overall healthier discussions online
Jaidka, Kokil and Zhou, Alvin and Lelkes, Yphtach, Brevity is the soul of Twitter: The constraint affordance and political discussion (November 20, 2018). https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3287552. Final version Journal of Communication, Volume 69, Issue 4, August 2019, Pages 345–372, https://doi.org/10.1093/joc/jqz023
Abstract: Many hoped that social networks would allow for the open exchange of information and a revival of the public sphere. Unfortunately, conversations on social media are often toxic and not conducive to healthy political discussion. Twitter, the most widely used social network for political discussions, doubled the limit of characters in a Tweet in November 2017, which provided a natural experiment to study the causal effect of technological affordances on political discussions with a discontinuous time series design. Using supervised and unsupervised natural language processing methods, we analyze 358,242 Tweet replies to U.S. politicians from January 2017 to March 2018. We show that the doubling the permissible length of a Tweet led to more polite, less informal, more analytical, and overall healthier discussions online. However, the declining trend in the political relevance of these tweets raises concerns about the implications of the changing norms for the quality of political deliberation.

Study with rats sheds light on why women are roughly twice as likely as men to develop depression, anxiety and other stress-related problems, including difficulty with attention
Early Life Stress Drives Sex-Selective Impairment in Reversal Learning by Affecting Parvalbumin Interneurons in Orbitofrontal Cortex of Mice. Haley L. Goodwill et al. Cell Reports, Volume 25, ISSUE 9, P2299-2307.e4, Nov 27 2018.
https://doi.org/10.1016/j.celrep.2018.11.010
Highlights
• Early life stress leads to select deficits in reversal learning in female mice
• Impaired rule-reversal learning is associated with decreased PV and GAD67 in OFC
• Optogenetic silencing of OFC PV+ cells recapitulates ELS effects on reversal learning
• Optogenetic silencing of mPFC PV+ cells impairs rule shifting, but not reversal learning
Summary: Poverty, displacement, and parental stress represent potent sources of early life stress (ELS). Stress disproportionately affects females, who are at increased risk for stress-related pathologies associated with cognitive impairment. Mechanisms underlying stress-associated cognitive impairment and enhanced risk of females remain unknown. Here, ELS is associated with impaired rule-reversal (RR) learning in females, but not males. Impaired performance was associated with decreased expression and density of interneurons expressing parvalbumin (PV+) in orbitofrontal cortex (OFC), but not other interneuron subtypes. Optogenetic silencing of PV+ interneuron activity in OFC of control mice phenocopied RR learning deficits observed in ELS females. Localization of reversal learning deficits to PV+ interneurons in OFC was confirmed by optogenetic studies in which neurons in medial prefrontal cortex (mPFC) were silenced and associated with select deficits in rule-shift learning. Sex-, cell-, and region-specific effects show altered PV+ interneuron development can be a driver of sex differences in cognitive dysfunction.

When asking for assistance, is it beneficial to incentivize a helper by offering a motivated gift (gift with the hope of getting support in return)? Sometimes undermine the assistance that people hope to receive. A third of Americans had given such gift at least once
aknin, Lara, Dylan Wiwad, and Yuthika Girme. 2018. “Not All Gifts Are Good: The Potential Practical Costs of Motivated Gifts.” PsyArXiv. November 27. doi:10.31234/osf.io/stkx8
Abstract: People rely on support from others to accomplish mundane and momentous tasks. When asking for assistance, is it beneficial to incentivize a helper by offering a motivated gift (i.e. a gift with the hope of getting support in return)? Six studies (N>2,500) examine the frequency and potential costs of motivated gifts. In Study 1, a third of Americans indicated that they had given a motivated gift at least once, while nearly two-thirds believed they had received one. In Studies 2a-d, most participants who imagined receiving a motivated gift before a favor request reported lower willingness to help and anticipated satisfaction from helping than participants who imagined simply being asked for a favor. Finally, Study 3 replicates these findings with actual help provided among friends in a laboratory setting. Findings suggest that motivated gifts are relatively common but may sometimes undermine the assistance that people hope to receive.

Dystopian novels/movies enhance the willingness to justify radical—especially violent—forms of political action; no evidence for the conventional wisdom that they reduce political trust & efficacy
It’s the End of the World and They Know It: How Dystopian Fiction Shapes Political Attitudes. Calvert W. Jones and Celia Paris. Perspectives on Politics, Volume 16, Issue 4, December 2018 , pp. 969-989. https://doi.org/10.1017/S1537592718002153
Abstract: Given that the fictional narratives found in novels, movies, and television shows enjoy wide public consumption, memorably convey information, minimize counter-arguing, and often emphasize politically-relevant themes, we argue that greater scholarly attention must be paid to theorizing and measuring how fiction affects political attitudes. We argue for a genre-based approach for studying fiction effects, and apply it to the popular dystopian genre. Results across three experiments are striking: we find consistent evidence that dystopian narratives enhance the willingness to justify radical—especially violent—forms of political action. Yet we find no evidence for the conventional wisdom that they reduce political trust and efficacy, illustrating that fiction’s effects may not be what they seem and underscoring the need for political scientists to take fiction seriously.

Men who more strongly endorsed hostile sexism underestimated the power they had compared with their partners’ reports; this perception predicted greater aggression toward female partners; this was not the result of generally being more dominant & aggressive
An Interdependence Account of Sexism and Power: Men's Hostile Sexism, Biased Perceptions of Low Power, and Relationship Aggression. Emily J. Cross, Nickola C. Overall, Rachel S.T. Low, & James K. McNulty. Journal of Personality and Social Psychology, Nov 26, 2018. http://dx.doi.org/10.1037/pspi0000167
Abstract: Protecting men’s power is fundamental to understanding the origin, expression, and targets of hostile sexism, yet no prior theoretical or empirical work has specified how hostile sexism is related to experiences of power. In the current studies, we propose that the interdependence inherent in heterosexual relationships will lead men who more strongly endorse hostile sexism to perceive they have lower power in their relationship, and that these perceptions will be biased. We also predicted that lower perceptions of power would in turn promote aggression toward intimate partners. Across 4 studies, men who more strongly endorsed hostile sexism perceived lower power in their relationships. Comparisons across partners supported that these lower perceptions of power were biased; men who more strongly endorsed hostile sexism underestimated the power they had compared with their partners’ reports of that power (Studies 1 and 2). These lower perceptions of power, in turn, predicted greater aggression toward female partners during couples’ daily interactions (Study 1), observed during couples’ video-recorded conflict discussions (Study 2), and reported over the last year (Studies 3 and 4). Moreover, the associations between hostile sexism, power, and aggression were specific to men perceiving lower relationship power rather than desiring greater power in their relationships (Studies 3 and 4), and they were not the result of generally being more dominant and aggressive (Studies 3 and 4), or more negative relationship evaluations from either partner (Studies 1– 4). The findings demonstrate the importance of an interdependence perspective in understanding the experiences, aggressive expressions, and broader consequences associated with hostile sexism.

Reading faces: Participants correctly identified the high-narcissism male & female, & the high-psychopathy male significantly more often than by chance, & the high-psychopathy female significantly less often
Are dark triad cues really visible in faces? Victor Kenji M. Shiramizu, Luca Kozm, Lisa M. DeBruine, Benedict C. Jones. Personality and Individual Differences, Volume 139, 1 March 2019, Pages 214-216. https://doi.org/10.1016/j.paid.2018.11.011
Abstract: The ‘dark triad’ refers to the personality traits narcissism, Machiavellianism and psychopathy. Previous research found that participants could distinguish dark triad faces when judging images with average facial characteristics of people who scored either high or low on these traits. These results suggest that faces contain valid cues to dark triad personality traits and that the dark triad is a set of physical-morphological characteristics, as well as a set of psycho-social characteristics. Because putative links between personality traits and facial appearance have often not replicated well across studies, we attempted to replicate these results with a new set of face images. Participants correctly identified the high-narcissism male and female prototypes and the high-psychopathy male prototype significantly more often than would be expected by chance. By contrast, our analyses showed no evidence that participants could discriminate between the high- and low-Machiavellianism prototypes for either sex. Surprisingly, participants correctly identified the high-psychopathy female prototype significantly less often than would be expected by chance alone. Together our results suggest that male and female faces contain valid cues of narcissism, but do not necessarily contain valid cues of psychopathy or Machiavellianism.

School achievement engenders high expectations about future prospects, yet markets are only contingently sensitive to that achievement; the misalignment schools-markets is perceived by academics as morally unacceptable
Magni-Berton, R., & Ríos, D. (2018). Why do academics oppose the market? A test of Nozick’s hypothesis. Current Sociology. https://doi.org/10.1177/0011392118812934
Abstract: In this article, the authors explore why academics tend to oppose the market. To this intent the article uses normative political theory as an explanatory mechanism, starting with a conjecture originally suggested by Robert Nozick. Academics are over-represented amongst the best students of their cohort. School achievement engenders high expectations about future economic prospects. Yet markets are only contingently sensitive to school achievement. This misalignment between schools and markets is perceived by academics – and arguably by intellectuals in general – as morally unacceptable. To test this explanation, the article uses an online questionnaire with close to 1500 French academic respondents. The data resulting from this investigation lend support to Nozick’s hypothesis.

Sensation seeking & the factor intellect/imagination predict liking of horror & frequency of use; gender, educational level, & age are also correlated; people seek out horror media with threatening stimuli that they perceive to be plausible
Clasen, M., Kjeldgaard-Christiansen, J., & Johnson, J. A. (2018). Horror, personality, and threat simulation: A survey on the psychology of scary media. Evolutionary Behavioral Sciences, http://dx.doi.org/10.1037/ebs0000152
Abstract: Horror entertainment is a thriving and paradoxical industry. Who are the consumers of horror, and why do they seek out frightening media? We provide support for the threat simulation theory of horror, according to which horror media provides a form of benign masochism that offers negative emotional stimulation through simulation of threat scenarios. Through an online survey of genre use and preference as well as personality traits and paranormal beliefs (n = 1,070), we find that sensation seeking and the fifth of the Big Five factors, intellect/imagination, predict liking of horror and frequency of use. Gender, educational level, and age are also correlated with horror liking and frequency of use (males show higher liking and more frequent use, whereas liking and use frequency are negatively correlated with educational level and age). People with stronger beliefs in the paranormal tend to seek out horror media with supernatural content, whereas those with weaker beliefs in the paranormal gravitate toward horror media with natural content, suggesting that people seek out horror media with threatening stimuli that they perceive to be plausible. While frightening media may be initially aversive, people high in sensation seeking and intellect/imagination, in particular, like intellectual stimulation and challenge and expect not just negative but also positive emotions from horror consumption. They brave the initially aversive response to simulate threats and so enter a positive feedback loop by which they attain adaptive mastery through coping with virtual simulated danger.

Normalized hurricane damage in the continental United States 1900–2017: Consistent with observed trends in the hurricane landfalls, the updated normalized loss estimates also show no trend
Normalized hurricane damage in the continental United States 1900–2017. Jessica Weinkle, Chris Landsea, Douglas Collins, Rade Musulin, Ryan P. Crompton, Philip J. Klotzbach & Roger Pielke Jr. Nature Sustainability (2018), https://www.nature.com/articles/s41893-018-0165-2
Abstract: Direct economic losses result when a hurricane encounters an exposed, vulnerable society. A normalization estimates direct economic losses from a historical extreme event if that same event was to occur under contemporary societal conditions. Under the global indicator framework of United Nations Sustainable Development Goals, the reduction of direct economic losses as a proportion of total economic activity is identified as a key indicator of progress in the mitigation of disaster impacts. Understanding loss trends in the context of development can therefore aid in assessing sustainable development. This analysis provides a major update to the leading dataset on normalized US hurricane losses in the continental United States from 1900 to 2017. Over this period, 197 hurricanes resulted in 206 landfalls with about US$2 trillion in normalized (2018) damage, or just under US$17 billion annually. Consistent with observed trends in the frequency and intensity of hurricane landfalls along the continental United States since 1900, the updated normalized loss estimates also show no trend. A more detailed comparison of trends in hurricanes and normalized losses over various periods in the twentieth century to 2017 demonstrates a very high degree of consistency.
Abstract: Direct economic losses result when a hurricane encounters an exposed, vulnerable society. A normalization estimates direct economic losses from a historical extreme event if that same event was to occur under contemporary societal conditions. Under the global indicator framework of United Nations Sustainable Development Goals, the reduction of direct economic losses as a proportion of total economic activity is identified as a key indicator of progress in the mitigation of disaster impacts. Understanding loss trends in the context of development can therefore aid in assessing sustainable development. This analysis provides a major update to the leading dataset on normalized US hurricane losses in the continental United States from 1900 to 2017. Over this period, 197 hurricanes resulted in 206 landfalls with about US$2 trillion in normalized (2018) damage, or just under US$17 billion annually. Consistent with observed trends in the frequency and intensity of hurricane landfalls along the continental United States since 1900, the updated normalized loss estimates also show no trend. A more detailed comparison of trends in hurricanes and normalized losses over various periods in the twentieth century to 2017 demonstrates a very high degree of consistency.
