Partisanship & stereotyping: Learning what car one drives (hybrid/pickup truck), where one buys coffee / eats fast food (Chipotle/Chick-fil-A), or where one works (college/bank) affect our willingness to interact

ABSTRACT: People use social cues to decide whether they want to interact with others. As everyday life has become more politicized, we now attach political meaning to seemingly apolitical activities, from the food we eat, to the movies and TV shows we watch, to the car we drive. Do these stereotypes affect social behavior? Using two survey experiments, including one with a nationally representative sample, I show that people use apolitical cues to draw inferences about others’ political leanings. More importantly, these inferences impact decisions about which individuals they want to interact with, which lead to reduced cross-party contact as well as cross-cutting political discussion. The findings have important implications for how partisan stereotypes of everyday attributes might indirectly exacerbate political polarization.

We find those who disagree with our art evaluations as more influenced by biases (conformity, financial incentives); reminding us of art preferences as “matters of opinion” reduced this thinking, but did not eliminate it

Seeing the subjective as objective: People perceive the taste of those they disagree with as biased and wrong. Nathan N. Cheek  Shane F. Blackman  Emily Pronin. Journal of Behavioral Decision Making, September 11 2020. https://doi.org/10.1002/bdm.2201

Abstract: People think that they see things as they are in “objective reality,” and they impute bias and other negative qualities to those who disagree. Evidence for these tendencies initially emerged in the domain of politics, where people tend to assume that there are objectively correct beliefs and positions. The present research shows that people are confident in the correctness of their views, and they negatively judge those who disagree, even in the seemingly “subjective” domain of art. Across seven experiments, participants evaluated paintings and encountered others who agreed or disagreed with their evaluations. Participants saw others' evaluations as less objective when they clashed with their own, and as more influenced by biasing factors like conformity or financial incentives. These aesthetic preferences felt as objective as political preferences. Reminding people of their belief that artistic preferences are “matters of opinion” reduced this thinking, but did not eliminate it. These findings suggest that people's convictions of their own objectivity are so powerful as to extend to domains that are typically regarded as “subjective.”

These studies confirm pets can be perpetrators of rejection and such rejection hurts similarly to if a human perpetrated it

https://doi.org/10.1521/jscp.2020.39.6.498

Abstract
Introduction: People can be rejected by friends, strangers, hated outgroups, or computer simulations. The present research examines whether people can be rejected by pets.

Methods: Two studies examined whether people can feel rejected by pets and how this affects their mood, fundamental needs, and aggression. Participants in Study 1 were directly rejected by a pet using an adapted version of the video message paradigm, and then reported on their mood, fundamental needs, and aggression. Study 2 directly compared differences in needs when writing about a rejection experience by a pet, a rejection experience by a person, and a control experience.

Results: Study 1 confirmed that people can feel rejected by their pets by demonstrating that those who were rejected felt more negatively and less positively and had decreased need satisfaction, however they did not experience any changes in their aggression. Finally, in Study 2, people who were rejected by a pet or by a person experienced decreased need satisfaction as compared to a control experience.

Discussion: Ultimately, these studies confirm pets can be perpetrators of rejection and such rejection hurts similarly to if a human perpetrated it. This may add to the growing body of research suggesting that pets do not provide uniformly positive effects on people.

This research documents a perfection premium in evaluative judgments wherein individuals disproportionately reward perfection on an attribute compared to near-perfect values on the same attribute

The Perfection Premium. Mathew S. Isaac, Katie Spangenberg. Social Psychological and Personality Science, September 10, 2020. https://doi.org/10.1177/1948550620944313

Abstract: This research documents a perfection premium in evaluative judgments wherein individuals disproportionately reward perfection on an attribute compared to near-perfect values on the same attribute. For example, individuals consider a student who earns a perfect score of 36 on the American College Test to be more intelligent than a student who earns a near-perfect 35, and this difference in perceived intelligence is significantly greater than the difference between students whose scores are 35 versus 34. The authors also show that the perfection premium occurs because people spontaneously place perfect items into a separate mental category than other items. As a result of this categorization process, the perceived evaluative distance between perfect and near-perfect items is exaggerated. Four experiments provide evidence in favor of the perfection premium and support for the proposed underlying mechanism in both social cognition and decision-making contexts.

Learning have long been implicated in influencing eating behavior; memory of recent eating modulates future food consumption; overweight and obesity is associated with impaired memory performance

Seitz, Benjamin M., A. J. Tomiyama, and Aaron Blaisdell. 2020. “Eating Behavior as a New Frontier in Memory Research.” PsyArXiv. September 11. doi:10.31234/osf.io/ry4nv

Abstract: The study of memory is commonly associated with neuroscience, aging, education, and eyewitness testimony. Here we discuss how eating behavior is also heavily intertwined—and yet considerably understudied in its relation to memory processes. Both are influenced by similar neuroendocrine signals (e.g., leptin and ghrelin) and are dependent on hippocampal functions. While learning processes have long been implicated in influencing eating behavior, recent research has shed light on how memory of recent eating modulates future food consumption. In humans, overweight and obesity is associated with impaired memory performance, and studies in rodents (and to a lesser extent humans) show that dietary-induced obesity causes rapid decrements to memory. Lesions to the hippocampus not only disrupt memory, but also induce obesity, highlighting a cyclic relationship between obesity and memory impairment. Enhancing memory of eating has been shown to reduce future eating and yet, very little is known about what influences memory of eating or how memory of eating differs from memory for other behaviors. We discuss recent advancements in these areas and highlight fruitful research pursuits afforded by combining the study of memory with the study of eating behavior.

When there is no alternative, boredom increases sadistic behavior across the board, even among individuals low in dispositional sadism

Pfattheicher, Stefan, Ljiljana B. Lazarevic, Erin C. Westgate, and Simon Schindler. 2020. “On the Relation of Boredom and Sadistic Aggression.” PsyArXiv. September 9. doi:10.31234/osf.io/r67xg

Abstract: What gives rise to sadism? While sadistic behavior (i.e., harming others for pleasure) is well-documented, past empirical research is nearly silent regarding the psychological factors behind it. We help close this gap by suggesting that boredom plays a crucial role in the emergence of sadistic tendencies. Across nine diverse studies, we provide correlational and experimental evidence for a link between boredom and sadism. We demonstrate that sadistic tendencies are more pronounced among people who report chronic proneness to boredom in everyday life (Studies 1A-1F, N = 1780). We then document that this relationship generalizes across a variety of important societal contexts, including online trolling; sadism in the military; sadistic behavior among parents; and sadistic fantasies (Studies 2-5, N = 1740). Finally, we manipulate boredom experimentally and show that inducing boredom increases sadistic behavior (i.e., killing worms; destroying other participants’ pay; Studies 6-9, N = 4097). However, alternatives matter: When several behavioral alternatives are available, boredom only motivates sadistic behavior among individuals with high dispositional sadism (Study 7). Conversely, when there is no alternative, boredom increases sadistic behavior across the board, even among individuals low in dispositional sadism (Studies 8 & 9). We further show that excitement and novelty seeking mediate the effects of boredom, and that boredom not only promotes sadistic (proactive) aggression, but reactive aggression as well (Study 9). Overall, the present work contributes to a better understanding of sadism and highlights the destructive potential of boredom. We discuss implications for basic research on sadism and boredom, as well as applied implications for society at large.

Development of sex differences in the human brain: Systematic sex difference in brain structure ocurred already during childhood, and subsequent increase of this difference during adolescence was large

Development of sex differences in the human brain. Florian Kurth , Christian Gaser & Eileen Luders. Cognitive Neuroscience, Sep 8 2020. https://doi.org/10.1080/17588928.2020.1800617

ABSTRACT: Sex differences in brain anatomy have been described from early childhood through late adulthood, but without any clear consensus among studies. Here, we applied a machine learning approach to estimate ‘Brain Sex’ using a continuous (rather than binary) classifier in 162 boys and 185 girls aged between 5 and 18 years. Changes in the estimated sex differences over time at different age groups were subsequently calculated using a sliding window approach. We hypothesized that males and females would differ in brain structure already during childhood, but that these differences will become even more pronounced with increasing age, particularly during adolescence. Overall, the classifier achieved a good performance, with an accuracy of 80.4% and an AUC of 0.897 across all age groups. Assessing changes in the estimated sex with age revealed a growing difference between the sexes with increasing age. That is, the very large effect size of d = 1.2 which was already evident during childhood increased even further from age 11 onward, and eventually reached an effect size of d = 1.6 at age 17. Altogether these findings suggest a systematic sex difference in brain structure already during childhood, and a subsequent increase of this difference during adolescence.

High Replicability of Newly-discovered Social-behavioral Findings Is Achievable; past failures to replicate may be attributable to departures from optimal procedures

Protzko, John, Jon Krosnick, Leif D. Nelson, Brian A. Nosek, Jordan Axt, Matthew Berent, Nick Buttrick, et al. 2020. “High Replicability of Newly-discovered Social-behavioral Findings Is Achievable.” PsyArXiv. September 10. doi:10.31234/osf.io/n2a9x

Abstract: Failures to replicate evidence of new discoveries have forced scientists to ask whether this unreliability is due to suboptimal implementation of optimal methods or whether presumptively optimal methods are not, in fact, optimal. This paper reports an investigation by four coordinated laboratories of the prospective replicability of 16 novel experimental findings using current optimal practices: high statistical power, preregistration, and complete methodological transparency. In contrast to past systematic replication efforts that reported replication rates averaging 50%, replication attempts here produced the expected effects with significance testing (p<.05) in 86% of attempts, slightly exceeding maximum expected replicability based on observed effect size and sample size. When one lab attempted to replicate an effect discovered by another lab, the effect size in the replications was 97% that of the original study. This high replication rate justifies confidence in rigor enhancing methods and suggests that past failures to replicate may be attributable to departures from optimal procedures.

Abstract
There has been extensive discussion about gender gaps in representation and career advancement in the sciences. However, psychological science itself has yet to be the focus of discussion or systematic review, despite our field’s investment in questions of equity, status, well-being, gender bias, and gender disparities. In the present article, we consider 10 topics relevant for women’s career advancement in psychological science. We focus on issues that have been the subject of empirical study, discuss relevant evidence within and outside of psychological science, and draw on established psychological theory and social-science research to begin to chart a path forward. We hope that better understanding of these issues within the field will shed light on areas of existing gender gaps in the discipline and areas where positive change has happened, and spark conversation within our field about how to create lasting change to mitigate remaining gender differences in psychological science.

Conservatives tended to show a greater interest in preserving their youthfulness, & had more resistant attitudes toward aging; & exhibited higher preferences for anti-aging benefits, compared to liberals & moderates

The Relationship between Political Ideology and the Pursuit of Staying Forever Young. Ga-Eun (Grace) Oh. Journal of Population Ageing (2020). Sep 5 2020. https://link.springer.com/article/10.1007/s12062-020-09302-6

Abstract: In an era defined by an aging population, the desire to look younger is so great, that the anti-aging industry is expected to grow by hundreds of billions of dollars within only a few years’ time. This research aims to investigate how the increasing interest to look younger is related to political ideology. We propose that accepting the ideal beauty of youthful bodies and pursuing physical youthfulness would be more prevalent among conservatives. We build this upon previous research showing that political conservatism is related to the acceptance of norms and values, as well as having strict boundaries for social perceptions and sensitivity to threat and losses. We conducted a pilot study which revealed that the queries related to anti-aging were more popular in states where political conservatism was higher in the US. Moreover, a survey among American participants revealed that conservatives tended to show a greater interest in preserving their youthfulness, and that they had more resistant attitudes toward aging. Moreover, they exhibited higher preferences for anti-aging benefits, compared to liberals and moderates. These findings contribute to extant literature on political psychology, body ideal, and ageism by demonstrating the relationship between political ideology and the pursuit of youthfulness, which is a neglected but critical dimension of the beauty ideal.

145 countries: subjective well-being is minimum, or nadir, in midlife around age 50

Is happiness U-shaped everywhere? Age and subjective well-being in 145 countries. David G. Blanchflower. Journal of Population Economics (2020). Sep 9 2020. https://link.springer.com/article/10.1007/s00148-020-00797-z

Abstract: A large empirical literature has debated the existence of a U-shaped happiness-age curve. This paper re-examines the relationship between various measures of well-being and age in 145 countries, including 109 developing countries, controlling for education and marital and labor force status, among others, on samples of individuals under the age of 70. The U-shape of the curve is forcefully confirmed, with an age minimum, or nadir, in midlife around age 50 in separate analyses for developing and advanced countries as well as for the continent of Africa. The happiness curve seems to be everywhere. While panel data are largely unavailable for this issue, and the findings using such data largely confirm the cross-section results, the paper discusses insights on why cohort effects do not drive the findings. I find the age of the minima has risen over time in Europe and the USA.

Conclusions

No ifs, no buts, well-being is U-shaped in age. The average age at which the U-shaped minimized across the 477 country-level estimates reported here is 48.3. It is in rich and poor countries.

I found evidence of the nadir in happiness in one hundred and forty-five countries, including one hundred and nine developing and thirty-six developed. I found it in Europe, Asia, North and South America, Australasia, and Africa. I identified it in all but six of the fifty-one European countries.Footnote26 I have a well-being U-shape for every one of the thirty-five member countries of the OECD.Footnote27 I have it for 138/193 member countries of the United Nations.

I found the well-being U-shape in English-speaking countries and non-English-speaking countries. A U-shape is revealed in countries ranked highly in the CIA World Factbook for countries with both high and low life expectancy at birth.Footnote28 I found it in twelve countries ranked in the top twenty for life expectancy of 82 or more.Footnote29 I also found a U-shape in ten countries in the bottom twenty for life expectancy of 223 countries in the world according to the CIA.Footnote30 The curve’s trajectory holds true in countries where the median wage is high and where it is not and where people tend to live longer and where they don’t.

I found additional evidence from an array of attitudinal questions that were worded slightly differently. Evidence of a U-shape was found across European countries in questions relating to an individual’s finances as well as to the state of the economy and democracy and how public services work. In Africa, I used a question that development scholars had used relating to living standards and found a U-shape for thirty African countries. This suggests the U-curve in age may have much broader applicability than just in well-being data. Given the robustness of these findings, it remains a puzzle why so many psychologists continue to suggest that well-being is unrelated to age.

People are struggling. In the USA, deaths of despair are most likely to occur in the middle-aged years, and the patterns are robustly associated with unhappiness and stress. Across countries, chronic depression and suicide rates peak in midlife. Those in middle age in the years since 2008 were most vulnerable to a once-in-a-generation financial shock especially if they were poor and with low levels of education. In the USA, the employment rate in 2020 was below that in 2008. In the UK, real wages were below pre-recession levels at the onset of the COVID-19 crash in March 2020. The financial crisis did not suddenly create frailty in downtrodden communities but simply exposed underlying problems with deep roots in the long decades before. It seems it is normal to have a midlife dip in well-being, but for many, especially those with the least skills, with little social support and few if any savings, that was too much to bear when a giant downturn came along in 2008.

The finding of a zenith in well-being in midlife likely adds important support to the notion that being in one’s forties and fifties exacerbates vulnerability to disadvantages and shocks.Footnote31 That is people with disabilities, less education, broken families, lost jobs, and so on are likely also to get hit hardest by the effects of aging. Some might face downward spirals as age and life circumstances interact. Many will not be getting the social/emotional support they need, because midlife is the worst time to present vulnerability. They will be dealing with shame and isolation, in addition to the first-order effects of whatever they are coping with in normal times at a midlife low is tough. It is made much harder when combined with a deep downturn especially when the speed of recovery and the length of lockdown is uncertain.

Interdisciplinary research is clearly needed into how to stem the worst manifestations of the midlife nadir in well-being, such as depression, lack of sleep, suicide, and higher tendency to drug and alcohol abuse. The fact that the happiness zenith occurs in developed and developing countries and it has even been found in great apes (Weiss et al. 2012) suggests there may be something deeply engrained perhaps in the genes.

The pandemic is global. Vulnerable individuals and communities around the world will be devastated by the shock, because of both job and income loss but also from bereavement. The prime aged with low levels of happiness already are especially at risk.

The happiness curve is found in 145 countries. No myth.

Caffeine Increases the Reinforcing Efficacy of Alcohol, an Effect that is Independent of Dopamine D2 Receptor Function

Caffeine Increases the Reinforcing Efficacy of Alcohol, an Effect that is Independent of Dopamine D2 Receptor Function. Sarah E Holstein, Gillian A. Barkell, Megan R. Young. bioRxiv, Sep 8 2020. https://doi.org/10.1101/2020.09.04.283465

Abstract: The rising popularity of alcohol mixed with energy drinks (AmEDs) has become a significant public health concern, with AmED users reporting higher levels of alcohol intake than non-AmED users. One mechanism proposed to explain heightened levels of alcohol intake in AmED users is that the high levels of caffeine found in energy drinks may increase the reinforcing properties of alcohol, an effect which may be dependent on interactions between adenosine signaling pathways and the dopamine D2 receptor. Therefore, the purpose of the current study was to confirm whether caffeine increases the reinforcing efficacy of alcohol using both fixed ratio (FR) and progressive ratio (PR) designs, and to investigate a potential role of the dopamine D2 receptor in caffeine's reinforcement-enhancing effects. Male Long Evans rats were trained to self-administer a sweetened alcohol or sucrose solution on an FR2 schedule of reinforcement. Pretreatment with caffeine (5-10 mg/kg) significantly increased operant responding for the sweetened alcohol reinforcer, but not sucrose. PR tests of motivation for alcohol or sucrose likewise confirmed a caffeine-dependent increase in motivation for a sweetened alcohol solution, but not sucrose. However, the D2 receptor antagonist eticlopride did not block the reinforcement-enhancing effects of caffeine using either an FR or PR schedule of reinforcement. Taken together, these results support the hypothesis that caffeine increases the reinforcing efficacy of alcohol, which may explain caffeine-induced increases in alcohol intake. However, the reinforcement-enhancing effects of caffeine appear to be independent of D2 receptor function.

In sum, personality is a powerful predictor of life outcomes with few moderated associations, above economic and social indicators

Beck, Emorie D., and Joshua J. Jackson. 2020. “A Mega-analysis of Personality Prediction: Robustness and Boundary Conditions.” PsyArXiv. September 9. doi:10.31234/osf.io/vsm9y

Abstract: Decades of studies identify personality traits as an important predictor of life outcomes. However, previous investigations of personality-outcome associations have not taken a principled approach to covariate use or other sampling strategies to ensure the robustness of personality-outcome associations. The result is that it is unclear (1) whether personality predicts important outcomes after accounting for a range of background variables, (2) for whom and when personality predictions hold, and 3) which background variables are most important to account for. The present study examines the robustness and boundary conditions of personality prediction using the Big Five to predict 14 health, social, education/work, and societal outcomes across eight different person- and study-level moderators using individual participant data from 171,395 individuals across 10 longitudinal panel studies in a mega-analytic framework. Robustness and boundary conditions were systematically tested using two approaches: propensity score matching and specification curve analysis. Three findings emerged: First, personality traits remain a robust predictor of life outcomes. Second, the effects generalize, as there are few moderators of personality-outcome associations. Third, robustness was differential across covariate choice in nearly half of the tested models, with the inclusion or exclusion of some of these flipping the direction of association. In sum, personality is a powerful predictor of life outcomes with few moderated associations. However, researchers need to be careful in their choices of covariates. We discuss how these findings can inform personality prediction, as well as recommendations for covariate inclusion.

No Fans, No Home Advantage. Sport Psychological Effects of Missing Supporters on Football Teams in European Top Leagues

Leitner, Michael C., and Fabio Richlan. 2020. “No Fans - No Home Advantage. Sport Psychological Effects of Missing Supporters on Football Teams in European Top Leagues.” PsyArXiv. September 9. doi:10.31234/osf.io/jqus9

Abstract
Introduction. Due to the COVID-19 pandemic, European top football (soccer) leagues played the final rounds of season 2019/20 without or strongly limited attendance of supporters (i.e., “ghost games”). From a sport psychological perspective this situation poses a unique opportunity to investigate the crowd’s influence on sports professionals’ behavior and performance.
Methods. A total of 1286 matches - played in the top leagues of Spain, England, Germany, Italy, Russia, Turkey, Austria and the Czech Republic - were analyzed for result, points, goals, fouls, bookings and reason for booking and contrasted between respective games of season 2018/19 (regular attendance) and season 19/20 (“ghost games”).
Results. There are three main findings. First, the marked home advantage identified in the regular 2018/19 season vanishes almost completely in the “ghost games” of the 2019/20 season. Second, home teams lose significantly more matches, whereas away teams win significantly more matches in “ghost games” compared to regular games. Third, home teams are booked significantly more often with yellow cards for committing fouls in “ghost games” relative to regular games.
Conclusion. We conclude that missing supporters in professional elite football leagues dissolve the “home advantage” effect. The missing support of a “home crowd” has also a direct effect on the experience, behavior and performance of home teams. Therefore home teams tend to compensate with increased aggressive behavior, resulting directly in more fierce tackles and ultimately in significantly more yellow cards awarded for foul play.

Face cells are not passive detectors of a particular constellation of low-level visual characteristics [but] can infer the presence of a face from the association with other objects

What does a “face cell” want?’ J. Taubert, S.G. Wardle, L.G.Ungerleider. Progress in Neurobiology, September 9 2020, 101880. https://doi.org/10.1016/j.pneurobio.2020.101880

Highlights
• We review the evidence that face cells respond more to faces than objects.
• We show evidence that face patches respond to objects with illusory facial features.
• This approach connects the response of face cells to visual perception.

Abstract: In the 1970s Charlie Gross was among the first to identify neurons that respond selectively to faces, in the macaque inferior temporal (IT) cortex. This seminal finding has been followed by numerous studies quantifying the visual features that trigger a response from face cells in order to answer the question; what do face cells want? However, the connection between face-selective activity in IT cortex and visual perception remains only partially understood. Here we present fMRI results in the macaque showing that some face patches respond to illusory facial features in objects. We argue that to fully understand the functional role of face cells, we need to develop approaches that test the extent to which their response explains what we see.

Patterns in Color-Emotion Associations Seem Universal, But Are Further Shaped by Linguistic and Geographic Proximity

Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity. Domicele Jonauskaite et al. Psychological Science, September 8, 2020. https://doi.org/10.1177/0956797620948810

Abstract: Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond those observed universally. Similarity was greater when nations were linguistically or geographically close. This study highlights robust universal color-emotion associations, further modulated by linguistic and geographic factors. These results pose further theoretical and empirical questions about the affective properties of color and may inform practice in applied domains, such as well-being and design.

Scientific objectivity _ Explaining Symmetry Across Sex in Intimate Partner Violence advancing core feminist principles: Evolution, Gender Roles, and the Will to Harm

Explaining Symmetry Across Sex in Intimate Partner Violence: Evolution, Gender Roles, and the Will to Harm. Hamel, John. Partner Abuse, Aug 24 2020. DOI: 10.1891/PA-2020-0014

Abstract: Intimate partner violence (IPV) is regarded by key stakeholders involved in shaping arrest and intervention policies as a gendered problem. The prevailing assumptions guiding these policies, centered on patriarchal social structures and men’s motivation to dominate their female partners, have collectively been called the gender paradigm. When states started to enact laws against domestic violence in the late 1970s, it was due to the efforts of battered women and their allies, including second wave feminists fighting for the political, social, and economic advancement of women. The focus was on life-threatening forms of abuse in which women represented, and continue to represent, the much larger share of victims. Since then, IPV has been found to be a more complex problem than originally framed, perpetrated by women as well as men, driven by an assortment of motives, and associated with distal and proximate risk factors that have little to do with gender. Nonetheless, the gender paradigm persists, with public policy lagging behind the empirical evidence. The author suggests some reasons why this is so, among them the much higher rates of violent crimes committed by men, media influence and cognitive biases, political factors, and perpetuation of the very sex-role stereotypes that feminists have sought to extinguish in every other social domain. He then critically reviews two theories used in support of the paradigm, sexual selection theory and social role theory, and explores how empirically driven policies would more effectively lower IPV rates in our communities, while advancing core feminist principles.

Against popular belief, the most attractive faces are not average face: Attractive features are at the outskirts of the natural distribution of face variations, suggesting a selection pressure away from the average

Zhan, Jiayu, Meng Liu, Oliver G. B. Garrod, Christoph Daube, Robin A. A. Ince, Rachael Jack, and Philippe schyns. 2020. “Beauty Is the Eye of the Cultural Beholder.” PsyArXiv. September 8. doi:10.31234/osf.io/34vsj

Abstract: Is face beauty universally perceived from a common basis of objectively definable face features, or is it irreducibly subjective and in the idiosyncratic eye of the cultural, or even individual beholder? We addressed this longstanding debate by objectively modelling the face beauty preferences of 80 individual male participants across Western European (WE) and East Asian (EA) cultures. With state-of-the-art 3D face capture technology, we derived a generative model that synthesized on each trial a random WE or EA female face whose shape and complexion is constrained by natural face variations. Each participant rated the attractiveness of the face on a Likert scale. We then reverse correlated these subjective ratings with the synthesized shape and complexion face parameters to reconstruct individual face models of attractiveness for same and other ethnicity faces. By analyzing the resulting 80 individual models and reconstructing the representation space of face beauty, we addressed several key questions. Against popular belief, we show that the most attractive faces are not average face. Instead, attractive features are at the outskirts of the natural distribution of face variations, suggesting a selection pressure away from the average. Such features also form their own subspace that is separate from cues of sexual dimorphism (i.e. masculine vs. feminine). Finally, we reveal the global preferences of face features across cultures, and specific cultural and individual participant idiosyncrasies. Our results therefore represent face attractiveness in its diversity to inform and impact fundamental theories of human social perception and signalling and the design of globalized digital avatars.

Whereas most researchers have thus far focused on exploratory investigations of this phenomenon, we experimentally manipulated contextual factors that could affect intrasexual competition (e.g., rival type, presence of a potential mate) and assessed competitive behavior via clothing choice. Across two studies, female MTurk users (NStudy1 = 131; NStudy2 = 262) read a vignette describing an upcoming party then chose an outfit they would wear to that party from a set of clothing items that had been pre-rated on sexiness and revealingness by a separate sample (N = 100). Within the vignette, we inserted participant-provided initials to manipulate the presence of a crush and the familiarity and attractiveness of their female party companion. Unexpectedly, we found a significant difference between outfit ratings for separates compared with dresses, so we incorporated this into our model. In study 1, among women who chose dresses, those who imagined attending the party with a more attractive acquaintance and their crush present chose more attractive outfits than women in the less attractive acquaintance condition. However, no such pattern was found for women who chose separates or women in the close friend condition. In study 2, a pre-registered direct replication showed that women in the acquaintance condition chose more attractive outfits than women in the close friend condition, but only in the crush present condition. Women’s intrasexual competition mechanisms appear cost-sensitive and only prompt competitive tactics when rivals are particularly threatening.

Are some first dates easier to read than others? Although it may be more difficult to form accurate impressions on first dates, targets higher in well-being may make the task easier

Are some first dates easier to read than others? The role of target well-being in distinctively accurate first impressions. Lauren Gazzard Kerra, James Borenstein-Laurie, Lauren J. Human. Journal of Research in Personality, September 8 2020, 104017. https://doi.org/10.1016/j.jrp.2020.104017

Highlights
• People can form accurate first impressions of personality on speed dates.
• Accuracy on speed dates tends to be lower than in platonic first impressions.
• Dates vary substantially in how accurately they are perceived.
• Dates higher in well-being are generally easier to read.

Abstract: Some people are open books, with their distinctive personalities being accurately perceived after a brief interaction, whereas others are harder to read. Such open books have in turn been found to have greater well-being, at least within lower-stakes, platonic getting-acquainted interactions. Do individual differences in expressive accuracy emerge in higher-stakes settings, such as first dates, and are people higher in well-being still easier to read? Using a speed-dating paradigm (N = 372; Ndyads = 4723), accuracy on average was significant but relatively low. Nevertheless, strong individual differences in expressive accuracy emerged and were associated with well-being. In sum, although it may be more difficult to form accurate impressions on first dates, targets higher in well-being may make the task easier.

Older brothers increase the odds of same-sex preference in pedohebephiles & teleiophiles; also replicated the recent finding that older sisters have a similar but weaker statistical association with the odds of homosexuality

Meta-Analyses of Fraternal and Sororal Birth Order Effects in Homosexual Pedophiles, Hebephiles, and Teleiophiles. Ray Blanchard, Klaus M. Beier, Francisco R. Gómez Jiménez, Dorit Grundmann, Jurian Krupp, Scott W. Semenyna & Paul L. Vasey. Archives of Sexual Behavior (2020). Sep 7 2020. https://link.springer.com/article/10.1007/s10508-020-01819-3

Abstract: This study investigated the relations between numbers of older brothers, numbers of older sisters, and the odds of homosexuality in later-born males, including males who are most attracted sexually to prepubescent or early pubescent children (pedohebephiles) and males who are most attracted sexually to adults (teleiophiles). The authors meta-analyzed data from 24 samples of homosexual and heterosexual men, originally reported in 18 studies, and totaling 18,213 subjects. The results confirmed that older brothers increase the odds of same-sex preference in pedohebephiles as they do in teleiophiles. They also replicated the recent finding that older sisters have a similar but weaker statistical association with the odds of homosexuality. These findings have two theoretical implications. First, the findings for older brothers and older sisters indicate some commonality in the factors that influence sexual preference in teleiophiles and those that influence sexual preference in pedohebephiles. Second, the finding for older sisters confirms a prediction stemming from the hypothesis that male fetuses stimulate maternal antibodies that increase the odds of homosexuality in later-born males. Such immunization could result from miscarried as well as full-term fetuses, and number of older sisters should correlate with number of male fetuses miscarried before gestation of the subject.

Abstract: Although much is currently known about hypersexuality (in the form of excessive sexual behavior) among sexual offenders, the degree to which hypersexual behavior is linked to paraphilic and especially pedophilic interests in non-forensic populations has not been established. The purpose of the present study was to elucidate the associations between total sexual outlets (TSO) and other sex drive indicators, antisocial behavior, pedophilic interests, and sexual offending behavior in a large population-based community sample of males. The sample included 8,718 German men who participated in an online study. Hypersexual behavior as measured by self-reported TSO, self-reported sex drive, criminal history, and pedophilic interests were assessed. In moderated hierarchical logistic regression analyses self-reported contact sexual offending against children was linked to sexual fantasizing about children and antisociality. There was no association between aggregated sex drive, and sexual abusive behaviour in the multivariate analyses. In contrast, self-reported child pornography consumption was associated with sex drive, sexual fantasies involving children, and antisociality. Nevertheless, in convicted sexual offenders antisociality, sexual preoccupation (like hypersexuality), and pedophilic interest are important predictors of sexual reoffending against prepubescent children. Therefore, in clinical practice an assessment of criminal history and pedophilic interests in hypersexual individuals and vice versa hypersexuality in antisocial or pedophilic men should be considered.

Abstract: Contrary to public perception, child sex offending (CSO) and paedophilia are not the same. Only half of all cases of CSO are motivated by paedophilic preference, and a paedophilic preference does not necessarily lead to CSO. However, studies that investigated clinical factors accompanying and contributing to paedophilia so far mainly relied on paedophiles with a history of CSO. The aim of this study was to distinguish between factors associated with sexual preference (paedophile versus non-paedophile) and offender status (with versus without CSO). Accordingly, a 2 (sexual preference) × 2 (offender status) factorial design was used for a comprehensive clinical assessment of paedophiles with and without a history of CSO (n = 83, n = 79 respectively), child sex offenders without paedophilia (n = 32) and healthy controls (n = 148). Results indicated that psychiatric comorbidities, sexual dysfunctions and adverse childhood experiences were more common among paedophiles and child sex offenders than controls. Offenders and non-offenders differed in age, intelligence, educational level and experience of childhood sexual abuse, whereas paedophiles and non-paedophiles mainly differed in sexual characteristics (e.g., additional paraphilias, onset and current level of sexual activity). Regression analyses were more powerful in segregating offender status than sexual preference (mean classification accuracy: 76% versus 68%). In differentiating between offence- and preference-related factors this study improves clinical understanding of both phenomena and may be used to develop scientifically grounded CSO prevention and treatment programmes. It also highlights that some deviations are not traceable to just one of these two factors, thus raising the issue of the mechanism underlying both phenomena.

In this research, the minds of men with overt erection (but not of men with flaccid penises) were perceived similarly to the minds of animals

An Experiencer, An Animal or An Object? Erection Salience Decreases Men’s Perceived Agency. Paulina Górska, Magdalena Budziszewska, Marta Marchlewska, Anna Stefaniak, Katarzyna Malinowska & Olga Kuzawińska. Archives of Sexual Behavior (2020). Sep 7 2020. https://link.springer.com/article/10.1007/s10508-020-01800-0

Abstract: Three experiments investigated the influence of penile erection on ascriptions of mental capabilities to men. Drawing on sexual objectification literature and the distinction between agency and experience in mind perception, three competing predictions were formulated. The mind redistribution hypothesis assumed that penile erection would lower agency and heighten experience attributions, the animalistic dehumanization hypothesis predicted the decrease in agency, but not experience, and the literal objectification hypothesis implied the simultaneous decrease in both agency and experience. In Experiment 1 (N = 219; 128 females), erection salience lowered agency, but not experience capabilities ascribed to male targets. Experiment 2 (N = 201, 113 females) replicated the negative effect of erection salience on perceived agency (but not experience) and revealed that erection salience lowered intentions to hire a male target. This effect was explained with the loss of perceived agency. Experiment 3 (N = 203, 98 females) verified the causal relationship between penile erection, agency and hiring intentions. Taken together, these results supported the animalistic dehumanization hypothesis.

Discussion

This research provides evidence that erection salience can influence how the mind of a male target is perceived. Across different domains (art and social media) and diverse cultural contexts (British and Polish), high erection salience decreased targets’ perceived agency, but did not affect their perceived experience. High erection salience had practical consequences: It translated to lower intentions to hire a target. Among female (but not male) participants, this effect was explained by the loss of perceived agency.

To the best of our knowledge, the present research is the first to examine the relation between erection salience and mind perception. While previous studies (e.g., Mautz, Wong, Peters, & Jennions, 2013) revealed that penis size determined a target’s attractiveness, they utilized solely flaccid penis stimuli and did not investigate other dimensions of social perception.

Our findings contribute to the sexual objectification and mind perception studies. Past results allowed for the formulation of three competing predictions for the influence of penile erection on agency and experience attributions. In the present research, the minds of men with overt erection (but not of men with flaccid penises) were perceived similarly to the minds of animals: as high in experience and low in agency capacities (Gray et al., 2007). As such, the effects of erection salience resemble the animalistic type of dehumanization, which denies uniquely human traits (e.g., self-control, civility, refinement, moral sensibility, logic and maturity), but not traits reflective of human nature (e.g., emotional responsiveness; see Haslam, 2006).

At the same time, the current results did not support the other two phenomena discussed in the literature. First, penile erection did not lead to literal objectification, which would involve a simultaneous decrease in agency and experience (Heflick & Goldenberg, 2014). Being a signal of sexual desire (an experience-related aspect of mind), erection seems to prevent perceiving men as emotionless objects. This result is congruent with the claim that literal objectification may be specific to female targets (e.g., Fredrickson & Roberts, 1997; Heflick & Goldenberg, 2014). Second, high erection salience did not lead to mind redistribution (Gray et al., 2011b). The decrease in target’s agency was not accompanied by an increase in experience. The lack of effects on experience may originate from the specific meaning attached to penile erection. As a symbol of power (Friedman, 2001), an erect penis may preclude seeing its owner as a harm-sensitive experiencer (Gray et al., 2011). In summary, the present research suggests that the belief expressed in the literature and conventional wisdom requires some qualifications: In the eye of the beholder, sexual arousal strips men of their agentic, but not their experiential mind.

Current results have practical implications. Whereas past research (Rollero & Tartaglia, 2013) revealed that objectification decreases men’s perceived suitability for certain (i.e., high status or stereotypically feminine) professions, the exact process underlying this effect has not been investigated. The present research adds to this line of inquiry by showing that, at least among female perceivers, this effect may be mediated by lowered agency ascribed to objectified male targets. Furthermore, as suggested by the results of Experiments 2 and 3, strong cues such as high erection salience may lower intentions to hire a target in general, regardless of profession. The current research does not, however, allow us to rule out alternative reasons for lower hiring intentions (e.g., target’s non-normative behavior as exemplified by exercising despite a visible erection).

Although the present research consisted of three experimental studies conducted with the use of different methods (computer-assisted Web interview in Experiment 1 and Experiment 3; paper and pencil method in Experiment 2) and among participants of different nationalities (British in Experiment 1 and Polish in Experiments 2 and 3), it nonetheless has some limitations. First of all, some of the reported effects may seem quite small, which may likely be a consequence of underpowered samples. This is the case, for example, in the analysis of the effect of agency manipulation in Experiment 3. Besides recruiting more participants, it would be possible to increase the effect sizes by using more powerful experimental manipulations (e.g., manipulating erection salience with the use of video stimuli). Second, our research utilized solely self-report measures, which may raise doubts related to social desirability bias or ecological validity of our questionnaires. Thus, future research is also needed to understand the influence of erection salience on men’s perceived agency in more realistic settings, which would ideally use behavioral, rather than self-report indicators. Third, future research should examine whether the pattern of results would be similar among people coming from different cultural and demographic backgrounds. Finally, when it comes to demographic variables, Experiment 2 demonstrated that the effect of erection salience on hiring intentions was mediated via target’s perceived agency. However, this effect was only significant among female participants which may suggest that male participants preferred not to hire a target with a visible erection because of reasons other than his alleged intellectual inferiority (e.g., intrasexual competition; Puts, Bailey, & Reno, 2015). Future research should explore the perception of social norms violation by the target as well as potential moderators and mediators of the described relation between erection salience and hiring intentions (among both males and females).

Adverse consequences faced by the targets of objectification are dire. They include social acceptability of violence and harassment directed at them (Loughnan et al., 2013), a tendency to self-objectify among the targets, as well as internalization of body focus and unrealistic body standards, lowered self-esteem, and in extreme cases depression, eating disorders and other serious psychological difficulties (e.g., Loughnan, Baldissarri, Spaccatini, & Elder, 2017, Loughnan et al., 2010). These negative effects are particularly strong if targets belong to low-status groups (e.g., sexual minorities; see Heimerdinger-Edwards et al., 2011; Rohlinger, 2002, Wiseman, & Moradi, 2010). Therefore, it seems especially important to identify the outcomes and processes related to sexual objectification. The present research was intended to serve this broader goal.

Biasing effect of advocacy: Not controllable but automatic, even in highly stable beliefs, when people were financially incentivized to form true beliefs & among lawyers (trained to prevent advocacy from biasing their judgements)

The automatic influence of advocacy on lawyers and novices. David E. Melnikoff & Nina Strohminger. Nature Human Behaviour (2020). Sep 7 2020. https://www.nature.com/articles/s41562-020-00943-3

Abstract: It has long been known that advocating for a cause can alter the advocate’s beliefs. Yet a guiding assumption of many advocates is that the biasing effect of advocacy is controllable. Lawyers, for instance, are taught that they can retain unbiased beliefs while advocating for their clients and that they must do so to secure just outcomes. Across ten experiments (six preregistered; N = 3,104) we show that the biasing effect of advocacy is not controllable but automatic. Merely incentivizing people to advocate altered a range of beliefs about character, guilt and punishment. This bias appeared even in beliefs that are highly stable, when people were financially incentivized to form true beliefs and among professional lawyers, who are trained to prevent advocacy from biasing their judgements.

Discussion
It may be no coincidence that, when describing biased thinking, psychologists reach for the metaphor of the advocate32–34. Our findings run counter to Gorgias’s assertion that one can advocate for a cause while remaining impartial. Instead, they support the Socratic view that advocacy induces an automatic cognitive bias, one that inevitably distorts the beliefs of those who merely assume the role of advocate.

In addressing whether the biasing effect of advocacy is uncontrollable, our findings leave open the question of whether this effect is unintentional, efficient or unconscious. Though all of these processing features fall under the umbrella of automaticity, the presence or absence of one cannot be inferred from the presence or absence of another8,10,11. Accordingly, additional work is needed to determine whether the biasing effect of advocacy can occur in the absence of a goal to advocate (unintentionally), under cognitive load (efficiently) or without the advocate’s awareness (unconsciously). Controllability, however, stands out among the various processing features as the most important for advocacy. The question of whether advocates can resist bias sparked the debate between Gorgias and Socrates, and the belief that they can continues to inform legal systems around the world4–7. That this belief may well be wrong has major implications for the law and beyond.

Lawyers are trusted to give their clients guidance based on objective, unbiased assessments of the evidence. When they cannot remain impartial, their advice will be of lower quality. For instance, a defence attorney who underestimates the likelihood of a guilty verdict may be less likely to advise his or her client to accept a plea bargain. Besides lawyers, many scientists aim to marry advocacy and impartiality by using their own research to influence policy decisions. Entrepreneurs have a vested interest in simultaneously pursuing the interests of their shareholders while retaining a realistic view of their company’s prospects.

The possibility remains, of course, that a means to control the biasing effect of advocacy will yet be discovered. Only through further investigation can the probability of finding such a strategy be so reduced that the biasing effect of advocacy can be declared, with practical certainty, uncontrollable. Until then, decision makers are advised that this bias seems remarkably difficult to overcome, and a reliable strategy for doing so remains elusive. Optimizing advocacy may depend not on controlling biased thinking but on external systems and structures that keep such thinking from shaping decisions.

November 15–18, 2019. http://www.sjdm.org/programs/2019-program.pdf

Abstract: We examine why people argue despite limited success in persuading others. In 10 experiments (N=2,911), our participants overclaim past argument success (Experiment 1) and mispredict future success (Experiments 2-6). Mispredicting future success results in higher entry into arguments and a greater willingness to bet money on predicted success (Experiment 2). Such biased assessments are robust to constrained definitions of winning (Experiments 3A-3D) and increases when the definition is based on logic (Experiment 4). Biased assessments of argument success seem to stem more from overconfidence in the "correctness" of individual's views than in debate skills (Experiment 5 & 6).

Men's frequently invoked tendency to predominate in mixed-gender political discussions failed to materialize

Who dominates the conversation? The effect of gender, discussion medium, and controversy on political discussion. Mary Herring, Jennie Sweet-Cushman, Elizabeth Prough & Fred Vultee. Feminist Media Studies, Aug 31 2020. https://doi.org/10.1080/14680777.2020.1808036

ABSTRACT: Previous research finds that when citizens discuss political topics, men tend to predominate. In this study, we investigate how discussion of political issues changes in different settings, using a design in which male and female participants discussed two political topics—one controversial, the other not—in in a variety of settings. We examine two aspects of discussion: the extent of participation and the style of participation. We find that women participate more extensively than men in general, but that this difference is conditioned on the gender composition of and the size of the group, and whether a topic is controversial. The discussion medium (online or face-to-face) exerts no impact on the extent of participation. Alternatively, whether discussants are agreeable in their comments is most influenced by the topic of discussion and, for men, whether the discussion occurs online or face-to-face.

No Evidence for a Relationship between Intelligence and Ejaculate Quality

No Evidence for a Relationship between Intelligence and Ejaculate Quality. Tara DeLecce, Bernhard Fink, Todd K. Shackelford, Mohaned G. Abed [in press, Evolutionary Psychology, September 2020]. http://www.toddkshackelford.com/downloads/Delecce-et-al-EP-sept.pdf

Abstract: Genetic quality may be expressed through many traits simultaneously, and this would suggest a phenotype-wide fitness factor. In humans, intelligence has been positively associated with several potential indicators of genetic quality, including ejaculate quality. We conducted a conceptual replication of one such study (Arden, Gottfredson, Miller, & Pierce, 2009) by investigating the relationship between intelligence (assessed by the Raven Advanced Progressive Matrices Test – Short Form) and ejaculate quality (indexed by sperm count, sperm concentration, and sperm motility) in a sample of 41 men (ages ranging 18 to 33 years; M = 23.33; SD = 3.60). By self-report, participants had not had a vasectomy, and had never sought infertility treatment. We controlled for several covariates known to affect ejaculate quality (e.g., abstinence duration before providing an ejaculate) and found no statistically significant relationship between intelligence and ejaculate quality; our findings, therefore, do not match those of Arden, Gottfredson, Miller, and Pierce (2009) or those of previous studies. We discuss limitations of this study and the general research area and highlight the need for future research in this area, especially the need for larger data sets to address questions around phenotypic quality and ejaculate quality.

Aphantasia (subjective impairment of face recognition and autobiographical memory): The current study provides tentative support for a link between aphantasia and autistic spectrum features

Abstract: Although Galton recognised in 1880 that some individuals lack visual imagery, this phenomenon was largely neglected over the following century. We recently coined the terms ‘aphantasia’ and ‘hyperphantasia’ to describe visual imagery vividness extremes, unlocking a sustained surge of public interest. Aphantasia is associated with subjective impairment of face recognition and autobiographical memory. Here we report the first systematic, wide-ranging neuropsychological and brain imaging study of people with aphantasia (n=24), hyperphantasia (n=25) and mid-range imagery vividness (n=20). Despite equivalent performance on standard memory tests, there were marked group differences on measures of autobiographical memory and imagination, participants with hyperphantasia outperforming controls who outperformed participants with aphantasia. Face recognition difficulties were reported more commonly in aphantasia. The Revised NEO Personality Inventory highlighted reduced extroversion in the aphantasia group and increased openness in the hyperphantasia group. Resting-state fMRI revealed stronger connectivity between prefrontal cortices and the visual network among hyperphantasic than aphantasic participants. In an active fMRI paradigm, there was greater anterior parietal activation among hyperphantasic and control than aphantasic participants when comparing visualisation of famous faces and places with perception. These behavioral and neural signatures of visual imagery vividness extremes validate and illuminate this significant but neglected dimension of individual difference.

The small effects of political advertising are small regardless of context, message, sender, or receiver: Evidence from 59 real-time randomized experiments

Abstract: Evidence across social science indicates that average effects of persuasive messages are small. One commonly offered explanation for these small effects is heterogeneity: Persuasion may only work well in specific circumstances. To evaluate heterogeneity, we repeated an experiment weekly in real time using 2016 U.S. presidential election campaign advertisements. We tested 49 political advertisements in 59 unique experiments on 34,000 people. We investigate heterogeneous effects by sender (candidates or groups), receiver (subject partisanship), content (attack or promotional), and context (battleground versus non-battleground, primary versus general election, and early versus late). We find small average effects on candidate favorability and vote. These small effects, however, do not mask substantial heterogeneity even where theory from political science suggests that we should find it. During the primary and general election, in battleground states, for Democrats, Republicans, and Independents, effects are similarly small. Heterogeneity with large offsetting effects is not the source of small average effects.

Liberals Report Lower Levels of Attitudinal Ambivalence Than Conservatives, despite conservatives been shown to be positively correlated with intolerance of ambiguity & negatively correlated with openness to new experiences

Liberals Report Lower Levels of Attitudinal Ambivalence Than Conservatives. Leonard Newman & Rikki Sargent. Social Psychological and Personality Science, July 22, 2020. https://journals.sagepub.com/doi/abs/10.1177/1948550620939798

Abstract: Political conservatism has been shown to be positively correlated with intolerance of ambiguity, need for closure, and dogmatism and negatively correlated with openness to new experiences and uncertainty tolerance. Those findings suggest that conservatism should also be negatively correlated with attitudinal ambivalence; by definition, ambivalent attitudes are more complex and more tinged with uncertainty than univalent attitudes. However, little published research addresses this issue. The results of five studies (total N = 1,049 participants) reveal instead that political liberalism is negatively associated with ambivalence. This finding held for both subjective and potential (i.e., formula-based) measures of ambivalence and for both politicized and nonpoliticized attitude objects. Conservatives may prefer uncomplicated and consistent ways of thinking and feeling, but that preference might not necessarily be reflected in the actual consistency of their mental representations. Possible accounts for these findings are discussed.

Journal of Experimental Psychology: General, August 13 2020. https://read.qxmd.com/read/32790460/the-confident-conservative-ideological-differences-in-judgment-and-decision-making-confidence

Abstract: In this research, we document the existence of broad ideological differences in judgment and decision-making confidence and examine their source. Across a series of 14 studies (total N = 4,575), we find that political conservatives exhibit greater judgment and decision-making confidence than do political liberals. These differences manifest across a wide range of judgment tasks, including both memory recall and “in the moment” judgments. Further, these effects are robust across different measures of confidence and both easy and hard tasks. We also find evidence suggesting that ideological differences in closure-directed cognition might in part explain these confidence differences. Specifically, conservatives exhibit a greater motivation to make rapid and efficient judgments and are more likely to “seize” on an initial response option when faced with a decision. Liberals, conversely, tend to consider a broader range of alternative response options before making a decision, which in turn undercuts their confidence relative to their more conservative counterparts. We discuss theoretical implications of these findings for the role of ideology in social judgment and decision-making.

Intolerance toward ideological outgroups: We show that conservatives are more ideologically intolerant than liberals and that the more intelligent are more ideologically intolerant than the less intelligent

Abstract: In this article we examine intolerance toward ideological outgroups, conceptualized as the negativity of the attitudes of liberals and conservatives toward their ideological outgroup. We show that conservatives are more ideologically intolerant than liberals and that the more intelligent are more ideologically intolerant than the less intelligent. We also show that the differences between liberals and conservatives and the differences between the more and less intelligent depend on ideological extremity: They are larger for extreme than for moderate ideologists. The implication of these results to questions regarding the relationship between intelligence and ideological intolerance and regarding the relationship between ideology and prejudice are discussed.

Women report lower subjective well-being in areas with more female-biased sex ratios, but males’ well-being was unaffected; I suggest that results may be due to their decreased bargaining power in the dating market

Richardson, Thomas. 2020. “The Effect of the Adult Sex Ratio on Subjective Well-being: Evidence from Europe.” PsyArXiv. September 7. doi:10.31234/osf.io/sb8w6

Abstract: In recent years researchers studying subjective well-being have found that ecological factors may underpin societal differences in happiness. The adult sex ratio, the number of males relative to females in an environment, influences many behaviours in both humans and non-human animals. However, the possible influence of the sex ratio on subjective well-being has received little attention. I investigated the relationship between the adult sex ratio and subjective well-being in over 29000 respondents 133 regions of Europe. I find that women report lower subjective well-being in areas with more female-biased sex ratios, but males’ well-being was unaffected. I did not find that the sex ratio influences sex specific probability of marriage or marriage rates overall. I find that increased population density is associated with lower well-being. Drawing from sociological and evolutionary theories, I suggest that results may be due to their decreased bargaining power in the dating market.

Getting Fewer “Likes” Than Others on Social Media Elicits Emotional Distress Among Victimized Adolescents

Getting Fewer “Likes” Than Others on Social Media Elicits Emotional Distress Among Victimized Adolescents. Hae Yeon Lee  Jeremy P. Jamieson  Harry T. Reis  Christopher G. Beevers  Robert A. Josephs  Michael C. Mullarkey  Joseph M. O’Brien  David S. Yeager. Child Development, September 6 2020. https://doi.org/10.1111/cdev.13422

Abstract: Three studies examined the effects of receiving fewer signs of positive feedback than others on social media. In Study 1, adolescents (N = 613, Mage = 14.3 years) who were randomly assigned to receive few (vs. many) likes during a standardized social media interaction felt more strongly rejected, and reported more negative affect and more negative thoughts about themselves. In Study 2 (N = 145), negative responses to receiving fewer likes were associated with greater depressive symptoms reported day‐to‐day and at the end of the school year. Study 3 (N = 579) replicated Study 1’s main effect of receiving fewer likes and showed that adolescents who already experienced peer victimization at school were the most vulnerable. The findings raise the possibility that technology which makes it easier for adolescents to compare their social status online—even when there is no chance to share explicitly negative comments—could be a risk factor that accelerates the onset of internalizing symptoms among vulnerable youth.

Culturally learned first impressions occur rapidly and automatically & emerge early in development; automaticity, rapid access, & early emergence are not evidence that first impressions have an innate origin

Culturally learned first impressions occur rapidly and automatically and emerge early in development. Adam Eggleston Jonathan C. Flavell  Steven P. Tipper  Richard Cook  Harriet Over. Developmental Science, Jul 20 2020. https://onlinelibrary.wiley.com/doi/abs/10.1111/desc.13021

Abstract: Previous research indicates that first impressions from faces are the products of automatic and rapid processing and emerge early in development. These features have been taken as evidence that first impressions have a phylogenetic origin. We examine whether first impressions acquired through learning can also possess these features. First, we confirm that adults rate a person as more intelligent when they are wearing glasses (Study 1). Next, we show this inference persists when participants are instructed to ignore the glasses (Study 2) and when viewing time is restricted to 100 milliseconds (Study 3). Finally, we show that six‐year‐old, but not 4‐year‐old, children perceive individuals wearing glasses to be more intelligent, indicating that the effect is seen relatively early in development (Study 4). These data indicate that automaticity, rapid access, and early emergence are not evidence that first impressions have an innate origin. Rather, these features are equally compatible with a learning model.

COVID-19: Higher media volume was associated with higher perceived knowledge, but not with higher actual knowledge; perceived threat was linked to perceived knowledge, but not to actual knowledge

Granderath, Julia S., Christina Sondermann, Andreas Martin, and Martin Merkt. 2020. “The Effect of Information Behavior in Media on Perceived and Actual Knowledge About the COVID-19 Pandemic.” PsyArXiv. September 7. doi:10.31234/osf.io/3y874

Abstract: The COVID-19 pandemic poses a global health threat that has dominated media coverage. However, not much is known about how individuals use media to acquire knowledge about COVID-19 under conditions of perceived threat. To address this, this study investigated how perceived threat affects media use (i.e., media volume and media breadth), and how media use in turn affects perceived and actual knowledge about COVID-19. In a German online survey, N = 952 participants provided information on their perceived threat and their media use to inform themselves about COVID-19. They further indicated how well they are informed about COVID-19 (perceived knowledge) and completed a COVID-19 knowledge test (actual knowledge). The results indicated that individuals who felt more threatened by COVID-19 used media more often to inform themselves (i.e., media volume), but focused on less different media channels (i.e., media breadth). Higher media volume was associated with higher perceived knowledge, but not with higher actual knowledge about COVID-19. Further, exploratory analyses revealed that perceived threat was linked to perceived knowledge, but not to actual knowledge. The association of perceived threat and perceived knowledge was mediated by increased media volume. Finally, a smaller media breadth was linked to higher perceived and actual knowledge.

Disgust Toward Interracial Couples may only emerge under certain conditions; current research offers limited support for the hypothesis that disgust response is exclusively linked to interracial unions

Disgust Toward Interracial Couples: Mixed Feelings About Black–White Race Mixing. Shoko Watanabe & Sean Laurent. Social Psychological and Personality Science, Jul 22 2020. https://journals.sagepub.com/doi/abs/10.1177/1948550620939411

Abstract: Three studies further explored Skinner and Hudac's (2017) hypothesis that interracial couples elicit disgust. Using verbal and face emotion measures (Study 1), some participants reported more disgust toward interracial couples than same-race White and Black couples. In Study 2, only people higher in disgust sensitivity tended to “guess” that rapidly presented images of interracial (vs. White) couples were disgusting. Study 3 used a novel image classification paradigm that presented couples side-by-side with neutral or disgusting images. Participants took longer to decide whether target images were disgusting only when interracial (vs. White) couples appeared next to neutral images. Greater sexual disgust heightened this difference. Mixed evidence suggesting an association of disgust with Black couples also emerged in Studies 2 and 3. Thus, the disgust–interracial romance association may only emerge under certain conditions, and the current research offers limited support for the hypothesis that disgust response is exclusively linked to interracial unions.

The deficit model states that incorrect opinions are a result of a lack of information; the cultural cognition model states that opinions are formed to maximize congruence with the group that one affiliates with

How others drive our sense of understanding of policies. NATHANIEL RABB, JOHN J. HAN & STEVEN A. SLOMAN. Behavioural Public Policy, September 2020. https://doi.org/10.1017/bpp.2020.40

Abstract: Five experiments are reported to compare models of attitude formation about hot-button policy issues like climate change. In broad strokes, the deficit model states that incorrect opinions are a result of a lack of information, while the cultural cognition model states that opinions are formed to maximize congruence with the group that one affiliates with. The community of knowledge hypothesis takes an integrative position. It states that opinions are based on perceived knowledge, but that perceptions are partly determined by the knowledge that sits in the heads of others in the community. We use the fact that people's sense of understanding is affected by knowledge of others’ understanding to arbitrate among these views in the domain of public policy. In all experiments (N = 1767), we find that the contagious sense of understanding is nonpartisan and robust to experimental manipulations intended to eliminate it. While ideology clearly affects people's attitudes, sense of understanding does as well, but level of actual knowledge does not. And the extent to which people overestimate their own knowledge partly determines the extremity of their position. The pattern of results is most consistent with the community of knowledge hypothesis. Implications for climate policy are considered.
