Pluck or Luck: Does Trait Variation or Chance Drive Variation in Lifetime Reproductive Success? Robin E. Snyder, and Stephen P. Ellner. The American Naturalist, https://www.journals.uchicago.edu/doi/abs/10.1086/696125
Abstract: While there has been extensive interest in how intraspecific trait variation affects ecological processes, outcomes are highly variable even when individuals are identical: some are lucky, while others are not. Trait variation is therefore important only if it adds substantially to the variability produced by luck. We ask when trait variation has a substantial effect on variability in lifetime reproductive success (LRS), using two approaches: (1) we partition the variation in LRS into contributions from luck and trait variation and (2) we ask what can be inferred about an individual’s traits and with what certainty, given their observed LRS. In theoretical stage- and size-structured models and two empirical case studies, we find that luck usually dominates the variance of LRS. Even when individuals differ substantially in ways that affect expected LRS, unless the effects of luck are substantially reduced (e.g., low variability in reproductive life span or annual fecundity), most variance in lifetime outcomes is due to luck, implying that departures from “null” models omitting trait variation will be hard to detect. Luck also obscures the relationship between realized LRS and individual traits. While trait variation may influence the fate of populations, luck often governs the lives of individuals.

No Evidence for Unethical Amnesia for Imagined Actions: A Failed Replication and Extension
Stanley, Matthew, Brenda W Yang, and Felipe De Brigard 2018. “No Evidence for Unethical Amnesia for Imagined Actions: A Failed Replication and Extension”. PsyArXiv. March 1. psyarxiv.com/kn8ce
Abstract: In a recent paper, Kouchaki and Gino (2016) suggest that memory for unethical actions is impaired, regardless of whether such actions are real or imagined. However, as we argue in the current paper, their claim that people develop “unethical amnesia” confuses two distinct and dissociable memory deficits: one affecting the phenomenology of remembering and another affecting memory accuracy. To further investigate whether unethical amnesia affects memory accuracy, we conducted three studies exploring unethical amnesia for imagined ethical violations. The first study (N = 228) attempts to directly replicate the only study from Kouchaki and Gino (2016) that includes a measure of memory accuracy. The second study (N = 232) attempts again to replicate these accuracy effects from Kouchaki and Gino (2016), while including several additional variables meant to potentially help in finding the effect. The third study (N = 228) is an attempted conceptual replication using the same paradigm as Kouchaki and Gino (2016), but with a new vignette describing a different moral violation. We did not find an unethical amnesia effect involving memory accuracy in any of our three studies. These results cast doubt upon the claim that memory accuracy is impaired for imagined unethical actions. Suggestions for further ways to study memory for moral and immoral actions are discussed.

Self-Presentation Concerns of Appearing Overly Moral
Good, but Not a Goody Two-Shoes: Self-Presentation Concerns of Appearing Overly Moral. Colleen M. Cowgill. Thesis presented to the College of Arts and Sciences of Ohio University, August 2017. http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1492991431186931
People are generally motivated to appear moral to others in order to gain trust and be liked. However, there may be conditions under which people may be motivated to appear less moral to others in order to be liked. Given previous research that people often tend to derogate and dislike "do-gooders" and "moral rebels," we hypothesized that people will be motivated to downplay their level of morality in interpersonal interactions after privately receiving feedback that they are far more moral than their peers. Furthermore, we predicted these effects would occur in the realm of morality, but not the realm of intelligence. Hypotheses were partially supported by the results of four studies. Although studies provided evidence that people prefer to be seen as intellectually superior to their peers rather than morally superior on affective measures, other studies provided no behavioral evidence that fear of being seen as a "goody-two-shoes" leads people to downplay their moral behavior.
Keywords: morality; self-presentation; overly moral; optimal distinctiveness

A recent study showed that participants derogated "moral rebels" who refused to participate in a racist task that the participants themselves agreed to take part in (Monin, Sawyer, Marquez, 2008). This effect was driven by the imagined or implicit reproach of the "moral rebels" against the complicit participants. In another study, participants who were asked to freely associate words with a target group (vegetarians) selected more words with negative connotations if they expected that target group to identify themselves as morally superior to the participants, who were meat-eaters (Minson &Monin, 2012).
Other research has shown that this phenomenon of derogating potentially morally superior others even appears in young children. Although children rated their peers as more likable if they were generous they liked generous children significantly less if those children were more generous than themselves - presumably because those children represented a threatening upward social comparison (Tasim, Dominquez, & Winn, 2015). These do-gooder derogation effects highlight an important potential drawback to being identified as "holier than thou." People tend not to like those they perceive as morally superior to themselves, or those they imagine as deeming themselves morally superior. Additionally, people in danger of being perceived as “holier than thou” may even face social penalties in the form of antisocial punishment.

Demographically diverse crowds are typically not much wiser than homogeneous crowds
Demographically diverse crowds are typically not much wiser than homogeneous crowds. Stephanie de Oliveira and Richard E. Nisbett. PNAS 2018 February, 115 (9) 2066-2071. https://doi.org/10.1073/pnas.1717632115
Significance: Leveraging social diversity to maximize group performance is an important challenge in the organizational sphere. Reported studies examine the effects of demographic diversity on the accuracy of “crowd” judgment—statistically aggregated individual judgments. Results suggest that demographic diversity does not boost crowds’ cognitive diversity to the extent necessary to make diverse crowds much wiser than homogeneous ones. A strong implication is that a decision to seek diverse opinion on matters of fact should be based on a cost/benefit analysis: Will a search for diversity likely pay off in increased accuracy? Payoffs can be maximized by using stronger correlates of cognitive diversity than demographic variables.
Abstract: Averaging independent numerical judgments can be more accurate than the average individual judgment. This “wisdom of crowds” effect has been shown with large, diverse samples, but the layperson wishing to take advantage of this may only have access to the opinions of a small, more demographically homogeneous “convenience sample.” How wise are homogeneous crowds relative to diverse crowds? In simulations and survey studies, we demonstrate three necessary conditions under which small socially diverse crowds can outperform socially homogeneous crowds: Social identity must predict judgment, the effect of social identity on judgment must be at least moderate in size, and the average estimates of the social groups in question must “bracket” the truth being judged. Seven survey studies suggest that these conditions are rarely met in real judgment tasks. Comparisons between the performances of diverse and homogeneous crowds further confirm that social diversity can make crowds wiser but typically by a very small margin.

Individuals cheat significantly more when they interact with a machine rather than a person, regardless of whether the machine is equipped with human features. When interacting with a human, individuals are particularly reluctant to report unlikely favorable outcomes
Honesty in the Digital Age. Alain Cohn, Tobias Gesche and Michel Maréchal (2018), University of Zurich, Working paper series / Department of Economics No. 280, http://www.econ.uzh.ch/static/workingpapers.php?id=959
Abstract: Modern communication technologies enable efficient exchange of information, but often sacrifice direct human interaction inherent in more traditional forms of communication. This raises the question of whether the lack of personal interaction induces individuals to exploit informational asymmetries. We conducted two experiments with 866 subjects to examine how human versus machine interaction influences cheating for financial gain. We find that individuals cheat significantly more when they interact with a machine rather than a person, regardless of whether the machine is equipped with human features. When interacting with a human, individuals are particularly reluctant to report unlikely favorable outcomes, which is consistent with social image concerns. The second experiment shows that dishonest individuals prefer to interact with a machine when facing an opportunity to cheat. Our results suggest that human interaction is key to mitigating dishonest behavior and that self-selection into communication channels can be used to screen for dishonest people.

What is mood? A computational perspective
What is mood? A computational perspective. James E Clark, Stuart Watson and Karl J Friston. Psychological Medicine, https://doi.org/10.1017/S0033291718000430
Abstract: The neurobiological understanding of mood, and by extension mood disorders, remains elusive despite decades of research implicating several neuromodulator systems. This review considers a new approach based on existing theories of functional brain organisation. The free energy principle (a.k.a. active inference), and its instantiation in the Bayesian brain, offers a complete and simple formulation of mood. It has been proposed that emotions reflect the precision of – or certainty about – the predicted sensorimotor/interoceptive consequences of action. By extending this reasoning, in a hierarchical setting, we suggest mood states act as (hyper) priors over uncertainty (i.e. emotions). Here, we consider the same computational pathology in the proprioceptive and interoceptive (behavioural and autonomic) domain in order to furnish an explanation for mood disorders. This formulation reconciles several strands of research at multiple levels of enquiry.

What do undergraduates learn about human intelligence? An analysis of introductory psychology textbooks
Warne, R. T., Astle, M. C., & Hill, J. C. (2018). What do undergraduates learn about human intelligence? An analysis of introductory psychology textbooks. Archives of Scientific Psychology, 6(1), 32-50. http://dx.doi.org/10.1037/arc0000038
Abstract: Human intelligence is an important concept in psychology because it provides insights into many areas, including neurology, sociology, and health. Additionally, IQ scores can predict life outcomes in health, education, work, and socioeconomic status. Yet, most students of psychology do not have an opportunity to take a class on intelligence. To learn what psychology students typically learn about intelligence, we analyzed 29 textbooks for introductory psychology courses. We found that over 3/4 of textbooks contained inaccurate statements. The five most commonly taught topics were IQ (93.1% of books), Gardner’s multiple intelligences (93.1%), Spearman’s g (93.1%), Sternberg’s triarchic theory (89.7%), and how intelligence is measured (82.8%). We learned that most introductory psychology students are exposed to some inaccurate information about intelligence and may have the mistaken impression that nonmainstream theories (e.g., Sternberg’s or Gardner’s theories) are as empirically supported mainstream theories (such as Spearman’s g).

Impact of Quran in Treatment of the Psychological Disorder and Spiritual Illness: 92.6% support the contention that the Quran has a significant healing influence
Impact of Quran in Treatment of the Psychological Disorder and Spiritual Illness. Ali Ali Gobaili Saged et al. Journal of Religion and Health, https://link.springer.com/article/10.1007/s10943-018-0572-8
Abstract: This paper studies the effect of Quranic therapy on psychological diseases and spiritual diseases. The experiments have been conducted on a random sample with 121 patients from both genders. The procedures that have been followed were different sessions with the patients, who were given some verses from the Holy Quran to listen within a specific period of time. After that, each patient was given a remedy program. This study aimed to measure the effectiveness and responsiveness of patients to receive treatment through Quran. This study highlighted the employment of a quantitative research, which achieved its objective through validity and reliability. The results of the effectiveness factor came after ability and willingness and gave a result of 92.6% for those who support the contention that the Quran has a significant healing influence. Also, some of the patients who regularly attended Quranic therapy sessions have been successfully cured, 81.8% of the sample believe that Quranic therapy sessions support their health needs. This study has empirically proved that the sound of the Holy Quran is an effective treatment for those who suffer from spiritual and psychological issues. Folk medicine and other traditional methods of treatment are important field of study that require further investigation. The study also illustrates that it’s highly important for patient to have confidence in his doctor or healer. Furthermore, our results show that the ability and willingness positively and significantly are related to the effectiveness and responsiveness, also effectiveness positively and significantly related to the responsiveness. Therefore, the patients satisfied to receive treatment through Quran and they have the ability and willingness to do so as they believe that Quran is an essential part of their life.

Individual variations in ratings of physical attractiveness were broadly unrelated to rater BMI and suggest that mutual attraction is an unlikely explanation for assortative mating for obesity
Wang, G., Ekeleme-Egedigwe, C. A., El Hamdouchi, A., Sauciuvenaite, J., Bissland, R., Djafarian, K., Ojiambo, R., Ramuth, H., Holasek, S., Lackner, S., Diouf, A., Hambly, C., Vaanholt, L.

(2018), Beauty and the Body of the Beholder: Raters’ BMI Has Only Limited Association with Ratings of Attractiveness of the Opposite Sex. Obesity, 26: 522–530. doi:10.1002/oby.22092
Abstract
Objective: Assortative mating for adiposity increases the genetic burden on offspring, but its causes remain unclear. One hypothesis is that people who have high adiposity find other people with obesity more physically attractive than lean people.
Methods: The attractiveness of sets of images of males and females who varied in adiposity were rated by opposite sex subjects (559 males and 340 females) across 12 countries.
Results: There was tremendous individual variability in attractiveness ratings. For female attractiveness, most males favored the leanest subjects, but others favored intermediate fatness, some were indifferent to body composition, and others rated the subjects with obesity as most attractive. For male images rated by females, the patterns were more complex. Most females favored subjects with low levels of adiposity (but not the lowest level), whereas others were indifferent to body fatness or rated the images depicting individuals with obesity as the most attractive. These patterns were unrelated to rater BMI. Among Caucasian males who rated the images of the thinnest females as being more attractive, the magnitude of the effect depended on rater BMI, indicating limited “mutual attraction.”
Conclusions: Individual variations in ratings of physical attractiveness were broadly unrelated to rater BMI and suggest that mutual attraction is an unlikely explanation for assortative mating for obesity.

Cross-national study, USA, Iran, Turkey, shows that the embodiment of an ideal sense of humor was predominantly a male figure
Is an Ideal Sense of Humor Gendered? A Cross-National Study. Sümeyr Tosun, Nafiseh Faghihi and Jyotsna Vaid. Front. Psychol., February 27 2018 | https://doi.org/10.3389/fpsyg.2018.00199
Abstract: To explore lay conceptions of characteristics of an ideal sense of humor as embodied in a known individual, our study examined elicited written narratives by male and female participants from three different countries of origin: United States, Iran, and Turkey. As reported in an earlier previous study with United States-based participants (Crawford and Gressley, 1991), our study also found that the embodiment of an ideal sense of humor was predominantly a male figure. This effect was more pronounced for male than for female participants but did not differ by country. Relative mention of specific humor characteristics differed by participant gender and by country of origin. Whereas all groups mentioned creativity most often as a component of an ideal sense of humor, this attribute was mentioned significantly more often by Americans than by the other two groups; hostility/sarcasm was also mentioned significantly more often by Americans than Turkish participants who mentioned it more often than Iranian participants. Caring was mentioned significantly more often by Americans and Iranians than by Turkish participants. These findings show a shared pattern of humor characteristics by gender but group differences in the relative prominence given to specific humor characteristics. Further work is needed to corroborate the group differences observed and to pinpoint their source.

How Pervasive Is Mind Wandering?
Seli, Paul, Roger E Beaty, James A Cheyne, Daniel Smilek, and Daniel L Schacter 2018. “How Pervasive Is Mind Wandering, Really?”. PsyArXiv. February 26. psyarxiv.com/9pruj
Abstract: Recent claims that people spend 40-50% of their waking lives mind wandering (MW) (Killingsworth & Gilbert, 2010; Kane et al. 2007) have become widely accepted and frequently cited. While acknowledging attention to be inconstant and wavering, and MW to be ubiquitous, we argue and present evidence that such simple quantitative estimates are misleading and potentially meaningless without serious qualification. MW estimates requiring dichotomous judgments of inner experience rely on questionable assumptions about how such judgments are made and the resulting data do not permit straightforward interpretations. We present evidence that estimates of daily-life MW vary dramatically depending on response options provided. Offering participants a range of options in estimating task engagement yielded variable MW estimates, from approximately 60% to 10%, depending on assumptions made about how observers make introspective judgments about their MW experiences and how they understand what it means to be on- or off-task.

‘You Do You’ Feminism: Lesbian, Bisexual, and Queer Women’s Perspectives on the Dildo
‘You Do You’ Feminism: Lesbian, Bisexual, and Queer Women’s Perspectives on the Dildo. Michaela Madraga, Elly-Jean Nielsen, Todd G. Morrison. Sexuality & Culture, https://link.springer.com/article/10.1007/s12119-018-9507-5
Abstract: Historically, feminists have engaged in a contentious debate about the dildo. Some assert that it is an oppressive tool of the patriarchy whereas others proclaim that it is a practical means of expressing lesbian, bisexual, and queer women’s sexuality. To gain some perspective into the current status of this debate, seven non-heterosexual women were interviewed about their attitudes toward dildos. Interviews were examined using inductive thematic analysis, and viewed through the lens of social constructionism. Rather than taking sides in the dildo debates, participants embraced a you do you ideology (i.e., there is no “right” or “wrong” answer when it comes to choosing whether to use or not use dildos). Three themes clustered around this overarching ideology: dildos are optional (à la carte dildo), meanings of dildos are contextually and phenomenologically determined (contextuality of the dildo), and dildos have theoretical implications (critically conscious queers). Participants’ eschewal of the binarized debate about the dildo may be entwined with changing understandings of feminist, gender, and queer theory.

Journalists continue to live in bubbles in their online interactions with each other; most journalists were more likely to interact with journalists who have the same gender, work in the same organization, on the same beat or in the same location
Journalistic Homophily on Social Media: Exploring journalists’ interactions with each other on Twitter. Folker Hanusch & Daniel Nölleke. Digital Journalism, https://doi.org/10.1080/21670811.2018.1436977
Abstract: Journalists have for considerable time been criticized for living in their own bubbles, a phenomenon industry commentators have referred to as groupthink, while in scholarship the tendency of individuals to connect with people who are like them is termed homophily. This age-old process has come under scrutiny in recent times due to the arrival of social network sites, which have been viewed as both working against but also leading to more homophily. In journalism scholarship, these processes are still little understood, however. Focusing on the social network site Twitter and drawing on a large-scale analysis of more than 600,000 tweets sent by 2908 Australian journalists during one year, this study shows that journalists continue to live in bubbles in their online interactions with each other. Most journalists were more likely to interact with journalists who have the same gender, work in the same organization, on the same beat or in the same location. However, the study also demonstrates some notable exceptions as well as the importance of differentiating between types of interaction.

Focusing on the social network site Twitter and drawing on a large-scale analysis of more than 600,000 tweets sent by 2908 Australian journalists during one year, this study shows that journalists continue to live in bubbles in their online interactions with each other. Most journalists were more likely to interact with journalists who have the same gender, work in the same organization, on the same beat or in the same location. However, the study also demonstrates some notable exceptions as well as the importance of differentiating between types of interaction.

There are no specific neurophysiological systems of positive or negative affect, and emotional valence is rather an integrative product of many brain systems during estimations of needs and the capacities required to satisfy these needs
Functionality versus dimensionality in psychological taxonomies, and a puzzle of emotional valence. Irina Trofimova. Proceedings of the Royal Society B, DOI: 10.1098/rstb.2017.0167
Abstract: This paper applies evolutionary and functional constructivism approaches to the discussion of psychological taxonomies, as implemented in the neurochemical model Functional Ensemble of Temperament (FET). FET asserts that neurochemical systems developed in evolution to regulate functional-dynamical aspects of construction of actions: orientation, selection (integration), energetic maintenance, and management of automatic behavioural elements. As an example, the paper reviews the neurochemical mechanisms of interlocking between emotional dispositions and performance capacities. Research shows that there are no specific neurophysiological systems of positive or negative affect, and that emotional valence is rather an integrative product of many brain systems during estimations of needs and the capacities required to satisfy these needs. The interlocking between emotional valence and functional aspects of performance appears to be only partial since all monoamine and opioid receptor systems play important roles in non-emotional aspects of behaviour, in addition to emotionality. This suggests that the Positive/Negative Affect framework for DSM/ICD classifications of mental disorders oversimplifies the structure of non-emotionality symptoms of these disorders. Contingent dynamical relationships between neurochemical systems cannot be represented by linear statistical models searching for independent dimensions (such as factor analysis); nevertheless, these relationships should be reflected in psychological and psychiatric taxonomies.

Media usage diminishes memory for experiences
Media usage diminishes memory for experiences. Diana I. Tamir et al. Journal of Experimental Social Psychology, Volume 76, May 2018, Pages 161–168, https://doi.org/10.1016/j.jesp.2018.01.006
Highlights
• Media use during an experience impairs memory for that experience.
• Media use impairs memory in controlled and naturalistic studies, solo and social experiences.
• Using media does not reliably reduce engagement or enjoyment of that experience.
Abstract: People increasingly use social media to record and share their experiences, but it is unclear whether or how social media use changes those experiences. Here we present both naturalistic and controlled studies in which participants engage in an experience while using media to record or share their experiences with others, or not engaging with media. We collected objective measures of participants' experiences (scores on a surprise memory test) as well as subjective measures of participants' experiences (self-reports about their engagement and enjoyment). Across three studies, participants without media consistently remembered their experience more precisely than participants who used media. There is no conclusive evidence that media use impacted subjective measures of experience. Together, these findings suggest that using media may prevent people from remembering the very events they are attempting to preserve.
