It’s a Boy! Evidence for Sex Ratio Adjustment in Humans. Kristen J. Navara. Chapter in Choosing Sexes pp 13-31. https://link.springer.com/chapter/10.1007/978-3-319-71271-0_2
Abstract: Since the beginning of human existence, there has been a keen interest in the factors that influence whether a boy or girl is produced and the development of practices or methods to control it. While the overall natal ratio of boys to girls produced by humans hovers at a stable 1.06 boys for every girl, there is now evidence that these sex ratios vary substantially among populations, in response to severe life events, in conjunction with the position and timing of intercourse, and even with ambient temperature. In this chapter, I compile the evidence implicating many of these factors as modulators of offspring sex ratios in humans and discuss how these influences may interact to determine whether a boy or a girl is produced.

The extraverted and individuals high on agreeablemenss are less likely to have negative affective evaluations of the opposing party
It’s Personal: The Big Five Personality Traits and Negative Partisan Affect in Polarized U.S. Politics. Steven W. Webster. American Behavioral Scientist, http://journals.sagepub.com/doi/abs/10.1177/0002764218756925?journalCode=absb
Abstract: One of the most important developments within the American electorate in recent years has been the rise of affective polarization. Whether this is due to notions of group-based conflict or ideological disagreement, Americans increasingly dislike the opposing political party and its supporters. I contribute to this growing literature on affective polarization by showing how differences in individuals’ Big Five personality traits are predictive of both whether an individual dislikes the opposing party and the degree to which they express this hostility. Modeling negative affect toward the opposing party as a two-stage process, I find that Extraverted individuals are less likely to have negative affective evaluations of the opposing party. Additionally, conditional on disliking the opposing party, my results indicate that higher levels of Agreeableness lowers the degree to which individuals dislike the out-party. Moreover, these relationships are substantively stronger than common sociodemographic predictors such as age, race, and educational attainment.

The Relationship Between Sexualized Appearance and Perceptions of Women’s Competence and Electability
The Relationship Between Sexualized Appearance and Perceptions of Women’s Competence and Electability. Julia K. Smith et al. Sex Roles, https://link.springer.com/article/10.1007/s11199-018-0898-4
Abstract: Women do not have a uniform or standardized “suit” to wear in the workplace so they must make daily decisions about what to wear. Some propose that women should dress in a sexualized way to gain power and influence, but sexy attire is related to lower perceptions of competence for women in leadership positions. We explored the effect of revealing or conservative attire on perceptions of women’s leadership competence. We also used eye-tracker technology to determine whether looking at sexualized body parts (i.e., breasts, hemline) was related to lower perceptions of leadership competence and electability. A female candidate for a student senate presidency at a U.S. university wearing revealing clothing was perceived by 191 college students as less honest and trustworthy, electable, and competent than one wearing conservative clothing. Sexualized body parts were looked at longer when the candidate was wearing revealing clothing compared to conservative clothing. Furthermore, mediation analyses indicated that the revealing clothing led participants to gaze at sexualized body parts, which, in turn, led to perceiving the candidate as less honest/trustworthy, which lowered their evaluations of her competence and electability. These findings suggest that viewing a woman in a sexy outfit can lead others to stare more at her body and make negative evaluations of her personal attributes. This finding has implications for the choices women make in workplace and leadership contexts.

Does it matter when we want to Be alone? Exploring developmental timing effects in the implications of unsociability. Robert J. Coplan, Laura L. Ooi, Danielle Baldwin. New Ideas in Psychology, https://doi.org/10.1016/j.newideapsych.2018.01.001
Highlights
• Unsociability refers to a non-fearful preference for solitude.
• We discuss various approaches to conceptualizing and measuring this construct.
• A theoretical model of developmental timing effects for unsociability is proposed.
• Links between unsociability and well-being may vary across development.
Abstract: Unsociability is a characteristic that refers to individual differences in the non-fearful preference for solitude. There is continued debate pertaining to the potential costs and benefits of solitude for our well-being. In this essay, we consider various approaches to the conceptualization and measurement of unsociability, and explore its implications for socio-emotional functioning. Further, we propose a somewhat speculative theoretical model of developmental timing effects for unsociability, which postulates non-linear variations in the implications of a heightened preference for solitude from early childhood to emerging adulthood. After considering the existing empirical support for this model, we outline remaining topics of concerns and suggest the most pressing directions for future research.
Keywords: Unsociability; Solitude; Social withdrawal; Preference for solitude; Developmental timing
---My question is: why then there is such apprehension in parents with child's unsociabilty? I trust the parents more than the researchers, something is not being captured in these samples we are studying.
Disclosure: I am quite unsocial.

Young infants expect an unfamiliar adult to comfort a crying baby: Evidence from a standard violation-of-expectation task and a novel infant-triggered-video task
Young infants expect an unfamiliar adult to comfort a crying baby: Evidence from a standard violation-of-expectation task and a novel infant-triggered-video task. Kyong-sunJin et al. Cognitive Psychology, Volume 102, May 2018, Pages 1-20. https://doi.org/10.1016/j.cogpsych.2017.12.004
Highlights
• We examined whether young infants would expect an adult to comfort a crying baby.
• 12- and 4-mo-olds showed this expectation in a standard violation-of-expectation task.
• 8-mo-olds showed this expectation in a new forced-choice infant-triggered-video task.
• Expectations about comforting actions are already present early in life.
• Our findings constrain theoretical accounts of early prosociality and morality.
Abstract: Do infants expect individuals to act prosocially toward others in need, at least in some contexts? Very few such expectations have been uncovered to date. In three experiments, we examined whether infants would expect an adult alone in a scene with a crying baby to attempt to comfort the baby. In the first two experiments, 12- and 4-month-olds were tested using the standard violation-of-expectation method. Infants saw videotaped events in which a woman was performing a household chore when a baby nearby began to cry; the woman either comforted (comfort event) or ignored (ignore event) the baby. Infants looked significantly longer at the ignore than at the comfort event, and this effect was eliminated if the baby laughed instead of cried. In the third experiment, 8-month-olds were tested using a novel forced-choice violation-of-expectation method, the infant-triggered-video method. Infants faced two computer monitors and were first shown that touching the monitors triggered events: One monitor presented the comfort event and the other monitor presented the ignore event. Infants then chose which event they wanted to watch again by touching the corresponding monitor. Infants significantly chose the ignore over the comfort event, and this effect was eliminated if the baby laughed. Thus, across ages and methods, infants provided converging evidence that they expected the adult to comfort the crying baby. These results indicate that expectations about individuals’ actions toward others in need are already present in the first year of life, and, as such, they constrain theoretical accounts of early prosociality and morality.

Exposure to predators does not lead to the evolution of larger brains in experimental populations of threespine stickleback
Samuk, K., Xue, J. and Rennision, D. J. (), Exposure to predators does not lead to the evolution of larger brains in experimental populations of threespine stickleback. Evolution. Accepted Author Manuscript. doi:10.1111/evo.13444
Abstract: Natural selection is often invoked to explain differences in brain size among vertebrates. However, the particular agents of selection that shape brain size variation remain obscure. Recent studies suggest that predators may select for larger brains because increased cognitive and sensory abilities allow prey to better elude predators. Yet, there is little direct evidence that exposure to predators causes the evolution of larger brains in prey species. We experimentally tested this prediction by exposing families of 1000–2000 F2 hybrid benthic-limnetic threespine stickleback to predators under naturalistic conditions, along with matched controls. After two generations of selection, we found that fish from the predator addition treatment had significantly smaller brains (specifically smaller telencephalons and optic lobes) than fish from the control treatment. After an additional generation of selection, we reared experimental fish in a common environment and found that this difference in brain size was maintained in the offspring of fish from the predator addition treatment. Our results provide direct experimental evidence that (a) predators can indeed drive the evolution of brain size – but not in the fashion commonly expected and (b) that the tools of experimental evolution can be used to the study the evolution of the vertebrate brain.

Causal effect of beliefs about skill on risky choices: Low (high) skill subjects are more (less) willing to take risks on gambles where the probabilities depend on relative skill
How do beliefs about skill affect risky decisions? Adrian Bruhin, Luís Santos-Pinto, David Staubli. Journal of Economic Behavior & Organization, https://doi.org/10.1016/j.jebo.2018.01.016
Highlights
• In this paper, we use a laboratory experiment to study the causal effect of beliefs about skill on risky choices.
• The paper offers an innovative experimental test that is free of strategic confounds and based on revealed preference.
• Low (high) skill subjects are more (less) willing to take risks on gambles where the probabilities depend on relative skill.
• This suggests that the wrong people may engage in risky activities V such as entering competitive markets or career paths V while the right people may be crowded out.
• Revealed beliefs are only moderately correlated with stated beliefs and so relying only on stated beliefs may be misleading.
Abstract: Beliefs about relative skill matter for risky decisions such as market entry, career choices, and financial investments. Yet in most laboratory experiments risk is exogenously given and beliefs about relative skill play no role. We use a laboratory experiment without strategy confounds to isolate the impact of beliefs about relative skill on risky choices. We find that low (high) skill individuals are more (less) willing to take risks on gambles where the probabilities depend on relative skill than on gambles with exogenously given probabilities. This happens because low (high) skill individuals overestimate (underestimate) their relative skill. Consequently, the wrong people may engage in risky activities where performance is based on relative skill while the right people may be crowded out.
Keywords: Individual risk taking behavior; Self-confidence; Laboratory experiment

Is Viewing Sexually Explicit Material Cheating on Your Partner? A Comparison Between the United States and Spain. Charles Negy et al. Archives of Sexual Behavior, https://link.springer.com/article/10.1007/s10508-017-1125-z
Abstract: This cross-sectional study examined whether university students from the U.S. (n = 392) and Spain (n = 200) considered the viewing of sexually explicit material (SEM) to be tantamount to committing infidelity. Participants’ ages ranged from 18 to 36 (U.S. sample) and 18 to 35 (Spain sample), respectively. At both universities, the study was made available to students via a computer program that allows recruitment and completion of the questionnaires online. It was found that the majority of U.S. and Spanish participants (73 and 77%, respectively) indicated that they did not consider viewing SEM as an act of infidelity. Also, overall, U.S. participants, those who were not currently in a relationship, and those who do not view SEM, were significantly more likely to believe that viewing SEM constituted infidelity compared to Spanish participants, those currently in a relationship, and those who view SEM. Finally, it was found that among U.S. and Spanish participants, intolerance of infidelity in general, negative attitudes toward SEM, and the proclivity for jealousy significantly correlated with believing that viewing SEM was tantamount to infidelity. For U.S. participants only, religiosity and (low) self-esteem also correlated with the belief that viewing SEM was infidelity. Implications of the findings are discussed.

Election turnout rates for women have even slightly exceeded turnout rates for men in recent elections due to the higher sense of civic duty of female citizens, which is due to higher level of conscientiousness than men
Why no gender gap in electoral participation? A civic duty explanation. Miguel Carreras. Electoral Studies, https://doi.org/10.1016/j.electstud.2018.01.007
Abstract: Previous research in comparative political behavior has generated an interesting paradox. Female citizens are less likely to engage in a variety of political activities (e.g. contacting politicians and working for parties), and are less cognitively engaged with the political process (i.e. they have lower levels of political interest and political efficacy). However, for reasons that remain unclear, several cross-national surveys reveal that there is no gender gap in electoral participation. In a number of countries, such as the United States, turnout rates for women have even slightly exceeded turnout rates for men in recent elections. I argue that the main reason for this pattern is the higher sense of civic duty of female citizens. This theory is grounded in research in social psychology that demonstrates that women have a higher level of conscientiousness than men. I use data from the 2014 ISSP Citizenship module to test my theoretical expectations, and find strong support for the argument that civic duty mediates the relationship between sex and electoral participation.

Physical beauty, social mobility, and optimistic dispositions
Things are looking up: Physical beauty, social mobility, and optimistic dispositions. R. Urbatsch. Social Science Research, https://doi.org/10.1016/j.ssresearch.2018.01.006
Abstract: Physical attractiveness tends to inspire friendlier reactions and more positive evaluations from others, so that the beautiful are likelier to succeed across many kinds of endeavors. Does this history of success lead to a more optimistic, hopeful attitude? Evidence from the 2016 General Social Survey and the 1972 National Election Study suggests that it often does: those whom interviewers rate as better-looking tend to report higher expectations that life will turn out well for them, and show signs of greater upward social mobility. Since optimism is itself an important contributor to success in many social endeavors, these findings suggest an understudied mechanism by which beauty leads to better life outcomes, as well as a means by which social interactions may shape personal dispositions.

Due to the innate need for preservation of a positive self-image, it is likely that teaching people about biases they hold, may cause a boomerang effect in cases where being associated with a specific bias implies negative social connotations
The boomerang effect of psychological interventions. Aharon Levy & Yossi Maaravi. Social Influence, Volume 13, 2018 - Issue 1, Pages 39-51. https://doi.org/10.1080/15534510.2017.1421571
Abstract: Research has found that teaching people about psychological biases can help counteract biased behavior. On the other hand, due to the innate need for preservation of a positive self-image, it is likely that teaching people about biases they hold, may cause a boomerang effect in cases where being associated with a specific bias implies negative social connotations. In the three studies below we examine situations in which psychological bias implies negatively associated behavior, and show that teaching people about bias in those contexts can be counterproductive.

Consensual Nonmonogamy: Psychological Well-Being and Relationship Quality Correlates
Consensual Nonmonogamy: Psychological Well-Being and Relationship Quality Correlates. Alicia N. Rubel & Anthony F. Bogaert. The Journal of Sex Research, Volume 52, 2015 - Issue 9, Pages 961-982. https://doi.org/10.1080/00224499.2014.942722
Abstract: Consensually nonmonogamous relationships are those in which all partners explicitly agree that each partner may have romantic or sexual relationships with others (Conley, Ziegler, Moors, Matsick, & Valentine, 2013 Conley, T. D., Ziegler, A., Moors, A. C., Matsick, J. L., & Valentine, B. (2013). In this article, research examining the associations between consensual nonmonogamy, psychological well-being, and relationship quality is reviewed. Specifically, three types of consensual nonmonogamy are examined: swinging, open relationships (including sexually open marriage and gay open relationships), and polyamory. Swinging refers to when a couple practices extradyadic sex with members of another couple; open relationships are relationships in which partners agree that they can have extradyadic sex; and polyamory is the practice of, belief in, or willingness to engage in consensual nonmonogamy, typically in long-term and/or loving relationships. General trends in the research reviewed suggest that consensual nonmonogamists have similar psychological well-being and relationship quality as monogamists. Methodological challenges in research on consensual nonmonogamy and directions for future research are discussed.

Internet pornography use is motivated by hedonic and self-focused sexual motivations, and is likely to lead to increases in hedonic sexual motivation both in solitary and in social sexual encounters
Grubbs, Joshua, Abby Braden, Shane W Kraus, Joshua Wilt, and Paul Wright 2017. “Pornography and Pleasure-seeking: Toward a Hedonic Reinforcement Model”. PsyArXiv. December 5. psyarxiv.com/jevb7
Abstract: Internet pornography use is a common recreational activity in developed nations, with substantial majorities of people from numerous countries reporting exposure to or consistent use this media. Despite this ubiquity, the majority of research on internet pornography use has been relegated to topical or specialty journals, with little attention psychological science at a broader level. This work seeks to consolidate this body of research into a novel theoretical framework that conceptualizes internet pornography use in terms that are relevant to the psychological sciences more broadly. This framework has been termed the Hedonic Reinforcement Model of pornography consumption. In support of this model, a review of research is conducted, demonstrating that internet pornography use may be seen as being influenced by and an influencer of human sexual motivation. In the first step of the present model, the present work contends that IPU is motivated by hedonic and self-focused sexual motivations, most often being a solitary, pleasure-seeking pursuit. Second, this model contends that IPU uniquely rewards hedonic motivations, due to its accessibility, novelty, and customizable nature. Finally, the present model contends that IPU is likely to lead to increases in hedonic sexual motivation both in solitary and in social sexual encounters.

Dictator game: Aversion to taking is strong, and dictators are willing to sacrifice 31% of endowment to avoid taking
Taking Aversion. Oleg Korenoka, Edward L. Millnera, Laura Razzolinib. Journal of Economic Behavior & Organization, https://doi.org/10.1016/j.jebo.2018.01.021
Highlights
• New experiment to measure whether dictators prefer a giving game to a taking game with identical payoff possibilities.
• Most dictators prefer the giving game
• Aversion to taking is strong: dictators are willing to sacrifice 31% of endowment to avoid taking.
• Consistent with Levitt and List's model of social preferences: moral cost of taking exceeds the moral cost of not giving.
Abstract: We determine whether the moral cost of taking exceeds the moral cost of not giving. We design and conduct an experiment to determine whether a dictator prefers a giving game over a taking game when the payoff possibilities are identical and to measure the strength of the preference. We find that aversion to taking is prevalent and strong. Over 85% of the dictators in our experiment choose to play a giving game over a taking game when the payoff possibilities are identical and, on average, dictators are willing to sacrifice over 31% of their endowment to avoid taking.

We design and conduct an experiment to determine whether a dictator prefers a giving game over a taking game when the payoff possibilities are identical and to measure the strength of the preference. We find that aversion to taking is prevalent and strong. Over 85% of the dictators in our experiment choose to play a giving game over a taking game when the payoff possibilities are identical and, on average, dictators are willing to sacrifice over 31% of their endowment to avoid taking.

Women were especially sensitive to laughter’s affiliative value, reporting greater disinterest in affiliating with targets laughing deliberately
Spontaneous Laughter as an Auditory Analog to Affiliative Intent. Mitch Brown, Donald F. Sacco, Steven G. Young. Evolutionary Psychological Science, https://link.springer.com/article/10.1007/s40806-017-0135-3
Abstract: Spontaneous laughter may serve as an auditory cue to affiliative intent within social contexts, whereas volitional laughter may connote deceptive, or non-affiliative, social communication. It would thus be advantageous to distinguish between affiliative and deceptive laughter to identify and prefer conspecifics genuinely interested in affiliating, particularly those whose current affiliative needs are unmet. Furthermore, women’s greater capability to discriminate between emotional cues should implicate them as being especially favorable toward spontaneous laughter. Because social exclusion heightens interest in affiliation, social exclusion should heighten favorability toward those communicating spontaneous laughter, which should be especially augmented among women. The current research examined both trait and state factors that might be moderate responses to spontaneous and volitional laughter. We experimentally activated affiliative motives and tasked men and women with indicating their preferences for spontaneous and volitional laughs. Although activation of affiliative needs did not alter preferences for laughter, participants ultimately preferred spontaneous laughs over volitional. Women were especially sensitive to laughter’s affiliative value, reporting greater disinterest in affiliating with targets emitting volitional laughs, a finding consistent with research indicating women’s heightened sensitivity toward affiliative cues and sensitivity to potentially exploitive conspecifics due to sexual dimorphism.

The origins of infants’ fairness concerns and links to prosocial behavior
The origins of infants’ fairness concerns and links to prosocial behavior. Jessica A. Sommerville, Elizabeth A. Enright. Current Opinion in Psychology, https://doi.org/10.1016/j.copsyc.2018.01.005
Highlights
• Infants possess a rudimentary sense of distributive fairness.
• Infants expect resources to be distributed equally to recipients.
• Infants evaluate individuals based on their adherence to fairness norms.
• Sharing experience may drive the developmental acquisition of fairness norms.
• Later, variability in the nature of infants’ sharing predicts fairness concerns.
• Limitations exist in infants’ fairness concerns: they do not punish unfair agents.
Abstract: Concerns about fairness are central to mature moral judgments. We review research regarding the origins of a sensitivity to distributive fairness, and how it relates to early sharing. Infants’ sensitivity to fairness appears to be commensurate with that of school-age children: infants notice violations to fairness norms and evaluate individuals based on their fair or unfair behavior. However, it may differ in other ways: there is no evidence that infants punish unfair individuals. Sharing behavior plays a role in both the developmental emergence of, and subsequent individual differences in, infants’ fairness concerns. These results motivate novel questions, such whether infants can entertain other models of fairness, whether infants’ socio-moral concerns hang together, and the relationship early fairness sensitivities and later fair behavior.

How Fleeting Is Fame? Collective Memory for Popular Music
Spivack, Stephen, Nathaniel H Spilka, and Pascal Wallisch 2018. “How Fleeting Is Fame? Collective Memory for Popular Music”. PsyArXiv. February 1. psyarxiv.com/tdfyc
Abstract: In this paper, we investigated the collective memory for popular music. To assess how well number-one hits are recognized over time, we randomly selected top songs from the last 76 years and presented them to a large sample of mostly millennial participants. In response to hearing each selection, participants were prompted to indicate whether they recognized each song. We found three distinct phases in collective memory: a steep linear drop-off in recognition for the music from this millennium, a stable plateau from the 1960s to the 1990s, and a further but more gradual drop-off for music from the 1940s and 1950s. More than half of recognition variability between songs can be accounted for by exposure as measured by Spotify play counts. We conclude that in the musical realm, fame is fleeting - but perhaps not as fleeting as previously suggested.

Languages with many speakers tend to be structurally simple while small communities sometimes develop languages with great structural complexity. The opposite pattern is observed for non-structural properties of language such as vocabulary size
Simpler grammar, larger vocabulary: How population size affects language. Florencia Reali, Nick Chater, Morten H. Christiansen. Proceedings of the Royal Society B, DOI: 10.1098/rspb.2017.2586
Abstract: Languages with many speakers tend to be structurally simple while small communities sometimes develop languages with great structural complexity. Paradoxically, the opposite pattern appears to be observed for non-structural properties of language such as vocabulary size. These apparently opposite patterns pose a challenge for theories of language change and evolution. We use computational simulations to show that this inverse pattern can depend on a single factor: ease of diffusion through the population. A population of interacting agents was arranged on a network, passing linguistic conventions to one another along network links. Agents can invent new conventions, or replicate conventions that they have previously generated themselves or learned from other agents. Linguistic conventions are either Easy or Hard to diffuse, depending on how many times an agent needs to encounter a convention to learn it. In large groups, only linguistic conventions that are easy to learn, such as words, tend to proliferate, whereas small groups where everyone talks to everyone else allow for more complex conventions, like grammatical regularities, to be maintained. Our simulations thus suggest that language, and possibly other aspects of culture, may become simpler at the structural level as our world becomes increasingly interconnected.

Warm and touching tears: tearful individuals are perceived as warmer because we assume they feel moved and touched
Warm and touching tears: tearful individuals are perceived as warmer because we assume they feel moved and touched. Janis H. Zickfeld & Thomas W. Schubert. Cognition and Emotion, https://doi.org/10.1080/02699931.2018.1430556
ABSTRACT: Recent work investigated the inter-individual functions of emotional tears in depth. In one study (Van de Ven, N., Meijs, M. H. J., & Vingerhoets, A. (2017). What emotional tears convey: Tearful individuals are seen as warmer, but also as less competent. British Journal of Social Psychology, 56(1), 146–160. Https://doi.org/10.1111/bjso.12162) tearful individuals were rated as warmer, and participants expressed more intentions to approach and help such individuals. Simultaneously, tearful individuals were rated as less competent, and participants expressed less intention to work with the depicted targets. While tearful individuals were perceived as sadder, perceived sadness mediated only the effect on competence, but not on warmth. We argue that tearful individuals might be perceived as warm because they are perceived as feeling moved and touched. We ran a pre-registered extended replication of Van de Ven et al. Results replicate the warmth and helping findings, but not the competence and work effects. The increase in warmth ratings was completely mediated by perceiving feeling moved and touched. Possible functions of feeling moved and touched with regard to emotional tears are discussed.

Do the Right Thing: Experimental evidence that preferences for moral behavior, rather than equity or efficiency per se, drive human prosociality
Do the Right Thing: Experimental evidence that preferences for moral behavior, rather than equity or efficiency per se, drive human prosociality. Valerio Capraro, David G. Rand. Judgment and Decision Making, Vol. 13, No. 1, January 2018, pp. 99-111. http://journal.sjdm.org/17/171107/jdm171107.html
Abstract: Decades of experimental research show that some people forgo personal gains to benefit others in unilateral anonymous interactions. To explain these results, behavioral economists typically assume that people have social preferences for minimizing inequality and/or maximizing efficiency (social welfare). Here we present data that cannot be explained by these standard social preference models. We use a “Trade-Off Game” (TOG), where players unilaterally choose between an equitable option and an efficient option. We show that simply changing the labelling of the options to describe the equitable versus efficient option as morally right completely reverses the correlation between behavior in the TOG and play in a separate Dictator Game (DG) or Prisoner’s Dilemma (PD): people who take the action framed as moral in the TOG, be it equitable or efficient, are much more prosocial in the DG and PD. Rather than preferences for equity and/or efficiency per se, our results suggest that prosociality in games such as the DG and PD are driven by a generalized morality preference that motivates people to do what they think is morally right.

Higher status people derogate ideological opponents less (i.e., evaluate them more charitably); greater rhetoric handling prowess (RHP: feeling more confident and less intimidated while arguing) mediates the effect

Social Cognition: Vol. 36, Special Issue: The Status of Status: Vistas from Social Cognition, pp. 43-77. https://doi.org/10.1521/soco.2018.36.1.43
Abstract: People tend to derogate their ideological opponents. But how does social status affect this tendency? We tested a prediction derived from hierometer theory that people with higher status would derogate ideological opponents less (i.e., evaluate them more charitably). We further predicted that greater rhetoric handling prowess (RHP: feeling more confident and less intimidated while arguing) would mediate the effect. Study 1 established a link between higher status and lesser opponent derogation correlationally. Study 2 did so experimentally. Using a scale to assess RHP developed and validated in Study 3, Study 4 established that RHP statistically mediated the correlational link between status and derogation. In Study 5, experimentally manipulating status affected RHP as predicted. However, in Study 6, experimentally manipulating RHP did not affect opponent derogation as predicted. Thus, our findings were substantially, but not entirely, consistent with our theoretically derived predictions. Implications for hierometer theory, and related theoretical approaches, are considered.

For the poor, thoughts about cost and money are triggered by mundane circumstances, they are difficult to suppress, they change mental associations, and they interfere with other experiences

Abstract: Recent research has studied how resource scarcity draws attention and creates cognitive load. As a result, scarcity improves some dimensions of cognitive function, while worsening others. Still, there remains a fundamental question: how does scarcity influence the content of cognition? In this article, we find that poor individuals (i.e., those facing monetary scarcity) see many everyday experiences through a different lens. Specifically, thoughts about cost and money are triggered by mundane circumstances, they are difficult to suppress, they change mental associations, and they interfere with other experiences. We suggest that the poor see an economic dimension to many everyday experiences that to others may not appear economic at all.

Androstadienone, a Chemosignal Found in Human Sweat, Increases Individualistic Behavior and Decreases Cooperative Responses in Men
Androstadienone, a Chemosignal Found in Human Sweat, Increases Individualistic Behavior and Decreases Cooperative Responses in Men. A Banner, I Frumin, S G Shamay-Tsoory. Chemical Senses, bjy002, https://doi.org/10.1093/chemse/bjy002
Abstract: A growing body of evidence suggests that humans can communicate socially relevant information, such as aggression, dominance and readiness for competition, through chemosensory signals. Androstadienone (androsta-4,16,-dien-3-one), a testosterone-derived compound found in men's axillary sweat, is a main candidate for a human pheromone that may convey such information. The current study aimed to investigate whether androstadienone serves as a chemosignaling threat cue to men, thus triggering avoidance behavior during competitive interaction with another man. In a double-blind, placebo-controlled, within-subject study design, 30 healthy, normosmic, heterosexual male participants completed the Social Orientation Paradigm (SOP), a monetary game played against a fictitious partner that allows three types of responses to be measured in the context of provocation: an aggressive response, an individualistic withdrawal response, and a cooperative response. Participants completed the SOP task twice, once under exposure to androstadienone and once under exposure to a control solution. The results indicate that androstadienone increased individualistic responses while it decreased cooperative responses. These findings support the role of androstadienone as a threatening signal of dominance that elicits behavioral avoidance and social withdrawal tendencies, possibly as a submissive response.

The echo chamber is overstated: the moderating effect of political interest and diverse media
The echo chamber is overstated: the moderating effect of political interest and diverse media. Elizabeth Dubois & Grant Blank. Information, Communication & Society, https://doi.org/10.1080/1369118X.2018.1428656
ABSTRACT: In a high-choice media environment, there are fears that individuals will select media and content that reinforce their existing beliefs and lead to segregation based on interest and/or partisanship. This could lead to partisan echo chambers among those who are politically interested and could contribute to a growing gap in knowledge between those who are politically interested and those who are not. However, the high-choice environment also allows individuals, including those who are politically interested, to consume a wide variety of media, which could lead them to more diverse content and perspectives. This study examines the relationship between political interest as well as media diversity and being caught in an echo chamber (measured by five different variables). Using a nationally representative survey of adult internet users in the United Kingdom (N = 2000), we find that those who are interested in politics and those with diverse media diets tend to avoid echo chambers. This work challenges the impact of echo chambers and tempers fears of partisan segregation since only a small segment of the population are likely to find themselves in an echo chamber. We argue that single media studies and studies which use narrow definitions and measurements of being in an echo chamber are flawed because they do not test the theory in the realistic context of a multiple media environment.

There is a small positive relation between service quality and percentage of a bill tipped; service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size
Banks, G. C., Woznyj, H. M., Kepes, S., Batchelor, J. H. and McDaniel, M. A. (), A meta-analytic review of tipping compensation practices: An agency theory perspective. Personnel Psychology. Accepted Author Manuscript. doi:10.1111/peps.12261
Tipping represents a form of compensation valued at over $50 billion a year in the U.S. alone. Tipping can be used as an incentive mechanism to reduce a principal-agent problem. An agency problem occurs when the interests of a principal and agent are misaligned and it is challenging for the principal to monitor or control the activities of the agent. However, past research has been limited in the investigation of the extent to which tipping is effective at addressing this problem. Following an examination of 74 independent studies with 12,271 individuals, meta-analytic results indicate that there is a small, positive relation between service quality and percentage of a bill tipped (rho =.15 without outliers). Yet, in support of the idea behind tipping, relative weights analyses illustrate that service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size. Evidence also suggests that racial minority servers tend to be tipped less than White servers (Cohen's d = .17), and females tend to be tipped more than males (Cohen's d = .15). Still, given the magnitude of the effect, one might question if tipping is an effective compensation practice to reduce the principal-agent problem. We discuss theoretical and practical implications for future research.

Only Bad for Believers? Religion, Pornography Use, and Sexual Satisfaction Among American Men
Only Bad for Believers? Religion, Pornography Use, and Sexual Satisfaction Among American Men. Perry, Samuel L., Whitehead, Andrew L. The Journal of Sex Research, https://doi.org/10.1080/00224499.2017.1423017
Abstract: Research has often demonstrated a negative association between pornography use and various intrapersonal and relationship outcomes, particularly for men. Several recent studies, however, have suggested that the negative association between pornography use and these indicators is stronger among more religious Americans, suggesting that moral incongruence (engaging in an activity that violates one’s sacred values) and the attendant shame or cognitive dissonance, rather than pornography use per se, may be the primary factor at work. The current study tested and extended this theory by examining how religion potentially moderates the link between pornography use and sexual satisfaction in a national random sample of American adults (N = 1,501). Analyses demonstrated that while pornography use was negatively associated with sexual satisfaction for American men (not women), among men who rarely attended religious services or held a low opinion of the Bible this negative association essentially disappeared. Conversely, the negative association between frequency of pornography consumption and sexual satisfaction was more pronounced for men with stronger ties to conventional religion. These findings suggest that the connection between pornography use and sexual satisfaction, especially for men, depends largely on what viewing pornography means to consumers and their moral community and less so on the practice itself.

Offspring sex ratio: Coital rates and other potential causal mechanisms
Offspring sex ratio: Coital rates and other potential causal mechanisms. William H.James, VictorGrech. Early Human Development, Volume 116, January 2018, Pages 24-27. https://doi.org/10.1016/j.earlhumdev.2017.10.006
Highlights
• Sex ratios at birth (SRB) are elevated by increased coital rates.
• Maternal stress induces male foetal losses.
• Periconceptual parental hormone concentrations may influence SRB.
• Understanding SRB influences may help understand causes of diseases with unusual SRB.
• E.g.: testicular cancer, hepatitis B, Toxoplasma gondii and, perhaps, prostatic cancer
Abstract: In recent years, scientists have begun to pay serious attention to the hypothesis that human parental coital rates around the time of conception causally influences the sexes of subsequent births. In this paper, the grounds of the argument are outlined. The point is important because, if the hypothesis were credible, it can potentially explain one of the best established (and otherwise unexplained) epidemiological features of sex ratio at birth – its rises during and just after World Wars 1 and 2 insofar as increased coital rates increase the ratio. Moreover, the greater the understanding of the variations of sex ratio at birth, the greater will be the understanding of the causes of those selected diseases associated with unusual sex ratios at birth (testicular cancer, hepatitis B, Toxoplasma gondii, and, perhaps, prostatic cancer).

Dharmapala, Dhammika and McAdams, Richard H. and Rappaport, John, The Effect of Collective Bargaining Rights on Law Enforcement: Evidence from Florida (December 31, 2017). University of Chicago Coase-Sandor Institute for Law & Economics Research Paper No. 831; U of Chicago, Public Law Working Paper No. 655. Available at SSRN: https://ssrn.com/abstract=3095217
Abstract: Growing controversy surrounds the impact of labor unions on law enforcement behavior. Critics allege that unions impede organizational reform and insulate officers from discipline for misconduct. The only evidence of these effects, however, is anecdotal. We exploit a quasi-experiment in Florida to estimate the effects of collective bargaining rights on law enforcement misconduct and other outcomes of public concern. In 2003, the Florida Supreme Court’s Williams decision extended to county deputy sheriffs collective bargaining rights that municipal police officers had possessed for decades. We construct a comprehensive panel dataset of Florida law enforcement agencies starting in 1997, and employ a difference-in-difference approach that compares sheriffs’ offices and police departments before and after Williams. Our primary result is that collective bargaining rights lead to about a 27% increase in complaints of officer misconduct for the typical sheriff’s office. This result is robust to the inclusion of a variety of controls. The time pattern of the estimated effect, along with an analysis using agency-specific trends, suggests that it is not attributable to preexisting trends. The estimated effect of Williams is not robustly significant for other potential outcomes of interest, however, including the racial and gender composition of agencies and training and educational requirements.

The effects of social priming, the voodoo theory of social psychology, manifested themselves only when the experiments weren't double blinded, exposing a self-fulfilling prophecy
The Role of Experimenter Belief in Social Priming. Thandiwe S. E. Gilder, Erin A. Heerey. Psychological Science, https://doi.org/10.1177/0956797617737128
Abstract: Research suggests that stimuli that prime social concepts can fundamentally alter people’s behavior. However, most researchers who conduct priming studies fail to explicitly report double-blind procedures. Because experimenter expectations may influence participant behavior, we asked whether a short pre-experiment interaction between participants and experimenters would contribute to priming effects when experimenters were not blind to participant condition. An initial double-blind experiment failed to demonstrate the expected effects of a social prime on executive cognition. To determine whether double-blind procedures caused this result, we independently manipulated participants’ exposure to a prime and experimenters’ belief about which prime participants received. Across four experiments, we found that experimenter belief, rather than prime condition, altered participant behavior. Experimenter belief also altered participants’ perceptions of their experimenter, suggesting that differences in experimenter behavior across conditions caused the effect. Findings reinforce double-blind designs as experimental best practice and suggest that people’s prior beliefs have important consequences for shaping behavior with an interaction partner.

Participants reported feeling younger than they actually were and wanting to be younger than their chronological age
Subjective Age and Its Correlates Among Middle-Aged and Older Adults. Shiri Shinan-Altman, Perla Werner. The International Journal of Aging and Human Development, https://doi.org/10.1177/0091415017752941
Abstract: The present study evaluates discrepancies in subjective age as reported by middle-age persons (aged 44–64 years) in comparison to older adults (aged 65 years and older), using a multidimensional definition of the concept. A convenience sample of 126 middle-aged and 126 older adults completed subjective age measures (felt age, desired age, and perceived old age), attitudes toward older adults, knowledge about aging, and sociodemographic questionnaires. Overall, participants reported feeling younger than they actually were and wanting to be younger than their chronological age. Perceived mean for old age was about 69 years. Discrepancies in felt age and desired age were significantly larger for the older group compared to the middle-aged group. Regarding perceived old age, compared to the younger group, older adults reported that old age begins at an older age. Findings suggest that middle-aged and older adults’ perceptions regarding themselves and regarding old age in general are independent and need, therefore, separate research and practical attention.

Men’s and Women’s Youngest and Oldest Considered and Actual Sex Partners
Antfolk, Jan, 2018. “Men’s and Women’s Youngest and Oldest Considered and Actual Sex Partners”. PsyArXiv. January 29. doi:10.1177/1474704917690401
Abstract: Whereas women prefer slightly older sexual partners, men—regardless of their age—have a preference for women in their twenties. Earlier research has suggested that this difference between the sexes’ age preferences is resolved according to women’s preferences. Earlier research has not, however, sufficiently considered that the age-range of considered partners might change over the life span. Here, we investigated the age limits (youngest and oldest) of considered and actual sex partners in a population-based sample of 2,655 adults (aged 18-50 years). Over the investigated age span, women reported a narrower age-range than men and women tended to prefer slightly older men. We also show that men’s age-range widens as they get older: While they continue to consider sex with young women, men also consider sex with women their own age or older. Contrary to earlier suggestions, men’s sexual activity thus reflects also their own age-range, although their potential interest in younger women is not likely converted into sexual activity. Compared to homosexual men, bisexual and heterosexual men were more unlikely to convert young preferences into actual behavior, supporting female-choice theory.

Participants liked targets less, were less romantically interested in targets, and rated targets as less attractive after discovering political dissimilarity with them
Mallinas, Stephanie, Jarret Crawford, and Shana Cole 2018. “Political Opposites Do Not Attract: The Effects of Ideological Dissimilarity on Impression Formation”. PsyArXiv. January 29. psyarxiv.com/p3j8v
Abstract: Past research shows that people like others who are similar to themselves, and that political partisans tend to dislike those with opposing viewpoints. Two studies examined how initial person impressions changed after discovering that the target held similar or dissimilar political beliefs. Using potential mates as targets, we found that participants liked targets less, were less romantically interested in targets, and rated targets as less attractive after discovering political dissimilarity with them. Further, they became more uncomfortable with targets after discovering ideological dissimilarity. Theoretical implications and suggestions for future research are discussed.

In women, pleasure prioritization & sexual agency are associated with lower odds of performing undesired sexual acts to please a partner—and sexual agency is associated with lower odds of succumbing to verbal pressure for intercourse
“Bad Girls” Say No and “Good Girls” Say Yes: Sexual Subjectivity and Participation in Undesired Sex During Heterosexual College Hookups. Heather Hensman Kettrey. Sexuality & Culture, https://link.springer.com/article/10.1007/s12119-018-9498-2
Abstract: Young people’s sexuality is often discursively constructed within the confines of a masculine/feminine binary that minimizes young women’s sexual subjectivity (i.e., desire, pleasure, and agency) while taking young men’s subjectivity for granted. Accordingly, young women who acknowledge themselves as sexual subjects are constructed as “bad girls” who incite males’ purportedly uncontrollable desire and, thus, invite undesired sexual attention. However, there is reason to hypothesize that young women who view themselves as sexual subjects may be less likely than other women to engage in undesired sexual activity (i.e., sex that their partners desire, but they do not desire for themselves). In this study, I used data from the Online College Social Life Survey (N = 7255) to explore relationships between two measures of sexual subjectivity (i.e., pleasure prioritization and sexual agency) and college women’s participation in undesired sexual activity during hookups (i.e., performance of undesired sexual acts to please a partner and succumbing to verbal pressure for intercourse). Logistic regression analyses suggest that pleasure prioritization and sexual agency are associated with lower odds of performing undesired sexual acts to please a partner—and sexual agency is associated with lower odds of succumbing to verbal pressure for intercourse. These findings point to the importance of sexuality education that includes discussions of women’s sexual subjectivity.

Consciousness of the Future as a Matrix of Maybe: Pragmatic Prospection and the Simulation of Alternative Possibilities
Baumeister, Roy, Heather M Maranges, and Hallgeir Sjåstad 2018. “Consciousness of the Future as a Matrix of Maybe: Pragmatic Prospection and the Simulation of Alternative Possibilities.”. PsyArXiv. January 29. psyarxiv.com/a3r7h
Abstract: Thinking about the future highlights the constructive nature of consciousness, as opposed to merely representing what is there — because the future is not yet available to be seen. We elaborate this point to emphasize how consciousness deals in alternative possibilities, and indeed preconscious interpretation confers meaning by recognizing these alternatives. Crucially, the goal of prospection is less to predict what is sure to happen than to prepare for action in situations defined by sets of incompatible alternative options, each of which might or might not come true. We review multiple lines of evidence indicating that people conceptualize the future as just such a matrix of maybe. Thus, people think of the future as highly changeable. Most prospective thinking involves planning, which is designed to bring about one outcome rather than alternatives. Optimism may often reflect an initial, automatic response that is soon followed by conscious appreciation of obstacles and other factors that can produce less desired, alternative outcomes. People moralize the future more than the past, presumably to promote the more desirable outcomes. Anticipated emotion helps people evaluate future possible outcomes. People specifically anticipate the matrix of maybe and sometimes seek to preserve multiplicity of options. We integrate these patterns of findings with a pragmatic theory of prospection: Thinking of the future as a multi-maybe matrix is useful for guiding action.
---
Recent laboratory work provides further evidence that it takes the power of conscious human thought to project the future as a matrix of maybe. Redshaw and Suddendorf (2016) provided dramatic evidence that human children far surpass adult nonhuman apes on this. Their apparatus was a tube shaped like an inverted Y. Thus, a ball or grape was dropped into the top and could come out either opening at the bottom. Either the participant caught it or it was gone. One could guess by holding one’s hand under either of the openings, thereby succeeding about half the time — or one could use both hands to cover both openings, thereby succeeding 100% of the time. Two-year-old human children failed to solve this, but three-year-olds and older children all soon achieved the perfect solution and caught the ball on every subsequent trial. In contrast, chimpanzees and orangutans never solved it. In fact, a couple of them stumbled by accident on the correct solution, happening to use both hands and catching the treat — but they failed to learn even from this success and on the next trial went back to one-hand guessing. Thus, success at this task required adjusting one’s behavior to the fact that two different outcomes are possible, and this was apparently beyond the mental powers of the smartest nonhuman primates, whereas human children could all figure it out. Human children could understand the future as multiple different maybes, but grownup apes apparently cannot think that way.

Unconscious bias in Australian Public Service shortlisting processes: APS officers discriminated in favour of female and minority candidates
Going blind to see more clearly: unconscious bias in Australian Public Service shortlisting processes. Results of a randomised controlled trial. Michael J. Hiscox, Tara Oliver, Michael Ridgway, Lilia Arcos-Holzinger, Alastair Warren and Andrea Willis. Behavioural Economics Team of the Australian Government (BETA) in partnership with the Australian Public Service Commission, Jun 2017. https://www.pmc.gov.au/domestic-policy/behavioural-economics/going-blind-see-more-clearly-unconscious-bias-australian-public-service-aps-shortlisting-processes
Women are under-represented in management and executive level positions across the private and public sectors. In 2016, women comprised 59.0% of the Australian Public Service (APS), but accounted for 48.9% of its executive level officers and only 42.9% of its Senior Executive Service (SES) officers. These statistics may reflect gender discrimination in hiring and promotion processes as a result of unconscious cognitive biases that affect decision-making.
Addressing the gender imbalance across the APS is the key priority of the Australian Public Service Gender Equality Strategy 2016-19. Aimed at driving high performance and boosting productivity the strategy calls for the APS to reflect contemporary reality and states that the APS must embrace diversity and that it should benefit from people of all backgrounds.
Study: This study aimed to test the magnitude of gender and ethnic minority bias in APS shortlisting processes, and the impact of introducing a gender/ethnicity-blind approach to reviewing job applications for shortlisting purposes.
The study was a randomised controlled trial conducted in partnership with 15 APS agencies. Participants were drawn from senior and executive level officers in these agencies. To identify any effects participants were asked to complete a fictitious shortlisting exercise with 16 fictitious CVs. The aim was to see whether de-identifying a CV (by removing a candidate’s name and personal information) changed the way it was assessed.
Results: The results showed that overall, de-identifying applications at the shortlisting stage does not appear to assist in promoting diversity within the APS in hiring. Overall, APS officers discriminated in favour of female and minority candidates.

We tend to considerably overestimate the extent to which party supporters belong to party-stereotypical groups, like 32% of Democrats are LGBT (6% in reality) and 38% of Republicans earn over $250,000 per year (2%)
The Parties in our Heads: Misperceptions About Party Composition and Their Consequences. Douglas J. Ahler, Gaurav Sood. Aug 2017, http://gsood.com/research/papers/partisanComposition.pdf
Abstract: We document a large and consequential bias in how Americans perceive the major political parties: people tend to considerably overestimate the extent to which party supporters belong to party-stereotypical groups. For instance, people think that 32% of Democrats are LGBT (vs. 6% in reality) and 38% of Republicans earn over $250,000 per year (vs. 2% in reality). Experimental data suggest that these misperceptions are genuine and party-specific, not artifacts of expressive responding, innumeracy, or ignorance of base rates. These misperceptions are widely shared, though bias in out-party perceptions is larger. Using observational and experimental data, we document the consequences of this perceptual bias. Misperceptions about out-party composition are associated with partisan affect, beliefs about out-party extremity, and allegiance to one’s own party. When provided information about the out-party’s actual composition, partisans come to see its supporters as less extreme and feel less socially distant from them.

Cross-cultural studies indicate that women's sexual attractiveness generally peaks before motherhood & declines with age. Cues of female youth are thought to be attractive because humans maintain long-term pair bonds, making reproductive value (future reproductive potential) particularly important to males
Male Chimpanzees Prefer Mating with Old Females. Martin N. Muller, Melissa Emery Thompson, Richard W. Wrangham. Current Biology, Volume 16, Issue 22, p2234–2238, November 21 2006. http://dx.doi.org/10.1016/j.cub.2006.09.042
Summary: Cross-cultural studies indicate that women's sexual attractiveness generally peaks before motherhood and declines with age [1]. Cues of female youth are thought to be attractive because humans maintain long-term pair bonds, making reproductive value (i.e. future reproductive potential) particularly important to males [2, 3]. Menopause is believed to exaggerate this preference for youth by limiting women's future fertility [1, 4]. This theory predicts that in species lacking long-term pair bonds and menopause, males should not exhibit a preference for young mates. We tested this prediction by studying male preferences in our closest living relative, the chimpanzee (Pan troglodytes). We show that despite their promiscuous mating system, chimpanzee males, like humans, prefer some females over others. However, in contrast to humans, chimpanzee males prefer older, not younger, females. These data robustly discriminate patterns of male mate choice between humans and chimpanzees. Given that the human lineage evolved from a chimpanzee-like ancestor, they indicate that male preference for youth is a derived human feature, likely adapted from a tendency to form unusually long term mating bonds

Romantic attraction, likelihood of selecting, & subsequent interpersonal outcomes with a dating partner almost exclusively depend on perception of the dating partner’s mate value: the higher, the better. No evidence for the idea that people feel attracted to & select dating partners whom they perceive to have a mate value similar to their own
Wurst, Stefanie N., Sarah Humberg, and Mitja Back 2018. “Preprint of "the Impact of Mate Value in First and Subsequent Real-life Romantic Encounters"”. Open Science Framework. January 26. osf.io/adej3
Abstract: We provide a first systematic investigation of the most prominent hypotheses about the impact of mate value on interpersonal attraction in real-life early-stage romantic encounters. Using Response Surface Analysis, we simultaneously examined how (a) people’s perception of their own mate value, (b) their perception of a potential partner’s mate value, and (c) the interplay between the two mate values impact initial romantic attraction and selection as well as subsequent interpersonal outcomes after selection. Data came from the “Date me for Science” speed-dating study (n = 398), in which participants who mutually selected each other at the speed-dating event were followed up with 3 assessments in the 6 weeks after the event to assess subsequent outcomes. Participants’ romantic attraction, likelihood of selecting, and subsequent interpersonal outcomes with a dating partner almost exclusively depended on their perception of their dating partner’s mate value: the higher, the better. There was no evidence for the popular matching hypothesis, which states that people feel attracted to and select dating partners whom they perceive to have a mate value similar to their own. Implications of these findings for theory and research on the impact of mate value on romantic attraction and selection are discussed.

Investigating the influence of symptoms of depression on the passive use of Facebook, as well as on selective self-presentation, and on negative perceptions of life
Passive Facebook-Nutzung, selektive Selbstdarstellung und negative Wahrnehmungen des eigenen Lebens: Mehrgruppen Cross-Lagged Panelanalysen zu differentiellen Effekten im Kontext psychologischen Wohlbefindens. Sebastian Scherr, Marlene Schmitt. In: M&K Medien & Kommunikationswissenschaft, Seite 58 - 74, Jahrgang 66 (2018), Heft 1, DOI 10.5771/1615-634X-2018-1-58
Abstract: We discuss findings from an online panel survey (n = 514) investigating the influence of symptoms of depression on the passive use of Facebook, as well as on selective self-presentation, and on negative perceptions of life over the course of one year. Drawing on multigroup cross-lagged panel analyses, the results of the study show that a depressive symptomatology is associated with negative perceptions of life that result from the viewing of other users’ photos. Contrary to many previous findings, selective self-presentation gained importance and increased passive forms of Facebook use as well as negative perceptions of life in the group of users with a severe depressive symptomatology. We discuss these findings in light of their implications for social media use in the course of a depression.

Contrary to many previous findings, selective self-presentation gained importance and increased passive forms of Facebook use as well as negative perceptions of life in the group of users with a severe depressive symptomatology. We discuss these findings in light of their implications for social media use in the course of a depression.
We explored crowdsourced ratings as a strategy to curb unrealistic optimism in advisors. Instead of calibrating expectations, these ratings propagated and exaggerated the unrealistic optimism
Leong, Y. C., & Zaki, J. (2018). Unrealistic optimism in advice taking: A computational account. Journal of Experimental Psychology: General, 147(2), 170-189. http://dx.doi.org/10.1037/xge0000382
Abstract: Expert advisors often make surprisingly inaccurate predictions about the future, yet people heed their suggestions nonetheless. Here we provide a novel, computational account of this unrealistic optimism in advice taking. Across 3 studies, participants observed as advisors predicted the performance of a stock. Advisors varied in their accuracy, performing reliably above, at, or below chance. Despite repeated feedback, participants exhibited inflated perceptions of advisors’ accuracy, and reliably “bet” on advisors’ predictions more than their performance warranted. Participants’ decisions tightly tracked a computational model that makes 2 assumptions: (a) people hold optimistic initial expectations about advisors, and (b) people preferentially incorporate information that adheres to their expectations when learning about advisors. Consistent with model predictions, explicitly manipulating participants’ initial expectations altered their optimism bias and subsequent advice-taking. With well-calibrated initial expectations, participants no longer exhibited an optimism bias. We then explored crowdsourced ratings as a strategy to curb unrealistic optimism in advisors. Star ratings for each advisor were collected from an initial group of participants, which were then shown to a second group of participants. Instead of calibrating expectations, these ratings propagated and exaggerated the unrealistic optimism. Our results provide a computational account of the cognitive processes underlying inflated perceptions of expertise, and explore the boundary conditions under which they occur. We discuss the adaptive value of this optimism bias, and how our account can be extended to explain unrealistic optimism in other domains.

Moral Self-judgment Is Stronger for Future Than Past Actions
Sjastad, Hallgeir, and Roy Baumeister. 2018. “Moral Self-judgment Is Stronger for Future Than Past Actions”. PsyArXiv. January 26. psyarxiv.com/8dawm
Abstract: When, if ever, would a person want to be held responsible for his or her choices? Across four studies (N = 915), people assigned more moral responsibility to themselves for their future than their past actions. This included thinking that they should receive more blame and punishment for future misdeeds than for past ones, and more credit and reward for future good deeds than for past ones. The tendency to moralize the future more than the past was mediated by anticipating (one’s own) emotional reactions and concern about one’s reputation, which was stronger in the future as well. The findings fit the pragmatic view that people moralize the future more than the past partly to guide their choices and actions, such as by increasing their motivation to restrain selfish impulses and build long-term cooperative relationships with others. We conclude that the psychology of moral responsibility has a strong future component.

Sexual Orientation and Leadership Suitability: How Being a Gay Man Affects Perceptions of Fit in Gender-Stereotyped Positions
Sexual Orientation and Leadership Suitability: How Being a Gay Man Affects Perceptions of Fit in Gender-Stereotyped Positions. Renzo J. Barrantes, A. Eaton. Sex Roles, https://link.springer.com/article/10.1007/s11199-018-0894-8
Abstract: The current set of studies examines perceptions of gay men’s fitness for leadership positions in the workplace. In two between-subjects experiments we examined the effect of a male employee’s sexuality on perceptions of his suitability for stereotypically feminine, masculine, and gender-neutral managerial positions, as well as potential mediators (perceptions of target agency and communion) and moderators (target out status) of these effects. In Study 1, 341 U.S. college student participants rated a gay male target as more communal and more suitable for feminine managerial positions than an otherwise identical heterosexual target, irrespective of his “out” status. Moreover, ratings of communion mediated the relationship between targets’ sexuality and suitability for feminine leadership. No differences between gay and heterosexual targets in targets’ agency or targets’ suitability for masculine or gender-neutral managerial positions were detected. Study 2 used a sample of 439 U.S. adults and an ambiguous target’s résumé to replicate and expand Study 1. This study provided participants with conflicting information on targets’ agency and communion, and it assessed the same dependent variables of targets’ agency, communion, and leadership suitability for various positions. Study 2 again found that ratings of communion significantly mediated the relationship between male targets’ sexuality and perceived suitability for feminine managerial roles. These findings extend previous research on perceptions of gay men in the workplace and have practical implications for being “out” at work.

Drivers of Rising Housing Construction Costs: city permitting processes, design and building code requirements, workforce regulations and ordinances, procurement requirements, and environmental regulations
Perspectives: Practitioners Weigh in on Drivers of Rising Housing Construction Costs in San Francisco. Carolina Reid and Hayley Raetz | Terner Center for Housing Innovation Blog, January 2018. https://ternercenter.berkeley.edu/blog/archives/2018/01 > http://ternercenter.berkeley.edu/uploads/San_Francisco_Construction_Cost_Brief_-_Terner_Center_January_2018.pdf
To provide just one example from a review of LIHTC cost certifications, in 2000, it cost approximately $265,000 per unit to build a 100-unit affordable housing building for families in the city, accounting for inflation. In 2016, a similar sized family building cost closer to $425,000 per unit, not taking into account other development costs (such as fees or the costs of capital) or changes in land values over this time period. As a result of these cost increases, developers need more subsidy for every unit, at a time when public resources for affordable housing have been dwindling.
[...]
[...] Macroeconomic conditions (including the cost of capital), labor market cycles and lack of skilled subcontractors, and trade policies (that influence the price of materials) all influence the cost of building.
But construction costs in San Francisco are also driven by local decisions and processes that are within the control of city agencies. Interviews and focus groups identified four local drivers of rising construction costs: city permitting processes, design and building code requirements, workforce regulations and ordinances, procurement (small and local business) requirements, and environmental regulations.

Despite participants’ unfamiliarity with the societies represented, the random sampling of each music excerpt, the very short duration, & the enormous diversity of this music, the ratings demonstrated accurate and cross-culturally reliable inferences about song functions on the basis of song forms alone
Form and Function in Human Song. Samuel A. Mehr et al. Current Biology, http://dx.doi.org/10.1016/j.cub.2017.12.042
Highlights
•People in 60 countries listened to songs from 86 mostly small-scale societies
•They successfully inferred song functions on the basis of song form alone
•Listener ratings were guided by both contextual and musical features of the songs
•Human song therefore exhibits widespread form-function associations
Summary: Humans use music for a variety of social functions: we sing to accompany dance, to soothe babies, to heal illness, to communicate love, and so on. Across animal taxa, vocalization forms are shaped by their functions, including in humans. Here, we show that vocal music exhibits recurrent, distinct, and cross-culturally robust form-function relations that are detectable by listeners across the globe. In Experiment 1 , internet users (n = 750) in 60 countries listened to brief excerpts of songs, rating each song’s function on six dimensions (e.g., “used to soothe a baby”). Excerpts were drawn from a geographically stratified pseudorandom sample of dance songs, lullabies, healing songs, and love songs recorded in 86 mostly small-scale societies, including hunter-gatherers, pastoralists, and subsistence farmers. Experiment 1 and its analysis plan were pre-registered. Despite participants’ unfamiliarity with the societies represented, the random sampling of each excerpt, their very short duration (14 s), and the enormous diversity of this music, the ratings demonstrated accurate and cross-culturally reliable inferences about song functions on the basis of song forms alone. In Experiment 2 , internet users (n = 1,000) in the United States and India rated three contextual features (e.g., gender of singer) and seven musical features (e.g., melodic complexity) of each excerpt. The songs’ contextual features were predictive of Experiment 1 function ratings, but musical features and the songs’ actual functions explained unique variance in function ratings. These findings are consistent with the existence of universal links between form and function in vocal music.

The Rising Importance of Muscularity in the Thin Ideal Female Body
Thin Is In? Think Again: The Rising Importance of Muscularity in the Thin Ideal Female Body. Frances Bozsik et al. Sex Roles, https://link.springer.com/article/10.1007/s11199-017-0886-0
Abstract: Research has documented an increased emphasis on fitness in media targeting women. However, it is unclear whether this emphasis has resulted in increased muscularity in the perceived ideal female body shape. We sought to evaluate whether the ideal female figure has incorporated increased muscularity into the existing ideal body type that already emphasizes thinness. In Study 1, 78 female undergraduates evaluated images of U.S. beauty pageant winners over the past 15 years on dimensions of thinness, muscularity, and attractiveness. Results indicated that muscularity and thinness ratings of pageant winners significantly increased over time. In Study 2, 64 female undergraduates evaluated two different versions of the same image of a model: a Thin Muscular image and a Thin Only image in which the appearance of muscularity was removed through digital editing. When images were presented in pairs, results indicated that participants found the Thin Muscular image more attractive than the Thin Only image. These results suggest that the current perceived ideal female figure includes both extreme thinness and muscularity and that women prefer this muscular thin figure to a solely thin figure. These findings have implications for clinical treatments related to body image, compulsive exercise, and media literacy.

Will a household return a letter that has been incorrectly addressed? On average, we find that half of all letters were returned
The Misaddressed Letter Experiment. Gweneth Leigh & Andrew Leigh. Applied Economics Letters, https://doi.org/10.1080/13504851.2018.1430323
ABSTRACT: We design a new field experiment to test pro-social behaviour: will a household return a letter that has been incorrectly addressed? On average, we find that half of all letters were returned. Return rates do not vary significantly according to the gender, race or ethnicity of the fictitious addressee. However, return rates are higher in more affluent neighbourhoods.

Back burners are desired prospective romantic/sexual partners that people communicate with to establish a future romantic or sexual relationship. Singles did not differ from those in committed romances in the number of back burners reported

Abstract: Back burners are desired prospective romantic/sexual partners that people communicate with to establish a future romantic or sexual relationship. We surveyed 658 college students about the extent to which they reported using various positive relationship maintenance strategies (positivity, openness, assurances) during communication with their most important back burner. Consistent with previous research, singles did not differ from those in committed romances in the number of back burners reported; however, singles and casual daters utilized the positive maintenance strategies to a greater extent than did those in committed relationships. Men reported using more assurances than did women, but the sexes did not differ on the other strategies utilized. Implications and limitations are discussed.

Letter to Mr Erdogan: "Worried by your health, Mr President"
To: President Erdogan, [xxx]@tccb.gov.tr
Subject: Worried by your health, Mr President
Dear Mr President, I am deeply worried about your health after reading the version of your words that the New York Times published a couple of days ago (https://www.nytimes.com/2018/01/22/world/middleeast/turkey-syria-kurds-us.html):
The lack of temperance, absent care with words, acute exhibition of lack of respect for the US and the US President, the null fear for consequences, show that the rumors that you reached a harsh deterioration of mental health are almost a certainty.
Pending a psychiatric evaluation, once we reached this point, to be of help to everyone involved, the people, the peace, the region's stability, the many lives involved, shouldn't be a good decision to leave power?
Those who review your speeches seem not to be really helpful, since comments like those above were, in the end, spoken.
Courage, Mr President! We all must know when to retire. Your age (in this specific case) and your poor decisions (like the the bad advisors you chose) seem to counsel your leaving the great office of the presidency for the many young and capable people that can do a better job for the people and the country.
May I suggest some spa in the Crimea? Or if you like not-so-warm weather, maybe a dacha in the mountains near Sochi, to have good laughs with the Great Statesman Mr Putin while having tea.
Best Regards,

On Monday, he took another swipe at the United States, saying, “Our country does not envy the soil of others.”
“When the operation achieves its aims, it would be over,” Mr. Erdogan told a group of businessmen in the presidential palace. “Some, or America, are asking us about the duration. And I am asking America, ‘Was your timing determined in Afghanistan?’ When the job is done. We are not eager to stay. We know when to pull out. And we do not care to have permission from anyone to do this.”

Mediatization and the Disproportionate Attention to Negative News. The case of airplane crashes
Mediatization and the Disproportionate Attention to Negative News. The case of airplane crashes. Toni G. L. A. van der Meer, Anne C. Kroon, Piet Verhoeven & Jeroen Jonkman. Journalism Studies, https://doi.org/10.1080/1461670X.2018.1423632
Abstract: Do news media increasingly portray a distorted world image when reporting menace? The purpose of this study is to investigate how media attention for negative incidents evolves over time and how this relates to real-world trends and public responses. A longitudinal content analysis (1991–2015) of media coverage of aviation incidents is used to provide a systematic investigation into the trends of media attention related to real-world data. Results show that while the total number of aviation incidents declined across time, relative media attention increased. Time series analysis revealed that media attention for these negative incidents was negatively associated with shifts in public responses—i.e. air travel behavior—whereas real-world statistics on aviation incidents did not seem to explain variation in public behavior. Moreover, when exploring the variation in the coverage of media attention, increasing presence of mediatization facets was observed as a potential explanation for the over-time rise in disproportional attention to negative news. In conclusion, news media may have a blind spot for progression and a distorted media reality can be a predictor of public responses instead of reality itself.

Chimpanzees appear to perceive similarity in primate faces in a similar way to humans. Information about perceptual similarity is likely prioritized over the potential influence of previous experience
Visual discrimination of primate species based on faces in chimpanzees. Duncan A. Wilson, Masaki Tomonaga. Primates, https://link.springer.com/article/10.1007/s10329-018-0649-8
Abstract: Many primate studies have investigated discrimination of individual faces within the same species. However, few studies have looked at discrimination between primate species faces at the categorical level. This study systematically examined the factors important for visual discrimination between primate species faces in chimpanzees, including: colour, orientation, familiarity, and perceptual similarity. Five adult female chimpanzees were tested on their ability to discriminate identical and categorical (non-identical) images of different primate species faces in a series of touchscreen matching-to-sample experiments. Discrimination performance for chimpanzee, gorilla, and orangutan faces was better in colour than in greyscale. An inversion effect was also found, with higher accuracy for upright than inverted faces. Discrimination performance for unfamiliar (baboon and capuchin monkey) and highly familiar (chimpanzee and human) but perceptually different species was equally high. After excluding effects of colour and familiarity, difficulty in discriminating between different species faces can be best explained by their perceptual similarity to each other. Categorical discrimination performance for unfamiliar, perceptually similar faces (gorilla and orangutan) was significantly worse than unfamiliar, perceptually different faces (baboon and capuchin monkey). Moreover, multidimensional scaling analysis of the image similarity data based on local feature matching revealed greater similarity between chimpanzee, gorilla and orangutan faces than between human, baboon and capuchin monkey faces. We conclude our chimpanzees appear to perceive similarity in primate faces in a similar way to humans. Information about perceptual similarity is likely prioritized over the potential influence of previous experience or a conceptual representation of species for categorical discrimination between species faces.

A Nuclear Twin Family Study of Self-Esteem
Bleidorn, W., Hufer, A., Kandler, C., Hopwood, C. J., and Riemann, R. (2018) A Nuclear Twin Family Study of Self-Esteem. Eur. J. Pers., doi: 10.1002/per.2136
Abstract: Twin studies suggest that both genes and environments influence the emergence and development of individual differences in self-esteem. However, different lines of research have emphasized either the role of genes or of environmental influences in shaping self-esteem, and the pathways through which genes and environments exert their influence on self-esteem remain largely unclear. In this study, we used nationally representative data from over 2000 German twin families and a nuclear twin family design (NTFD) to further our understanding of the genetic and environmental influences on individual differences in self-esteem. Compared with classical twin designs, NTFDs allow for finer-grained descriptions of the genetic and environmental influences on phenotypic variation, produce less biased estimates of those effects, and provide more information about different environmental influences and gene–environment correlation that contribute to siblings' similarity. Our NTFD results suggested that additive and non-additive genetic influences contributed to individual differences in self-esteem as well as environmental influences that are both shared and not shared by twins. The shared environmental component mostly reflected non-parental influences. These findings highlight the increased sensitivity afforded by NTFDs but also remaining limitations that need to be addressed by future behavioural genetic work on the sources of self-esteem.

Effects of physical attractiveness on political beliefs: more attractive individuals are more likely to report higher levels of political efficacy, identify as conservative, and identify as Republican
Effects of physical attractiveness on political beliefs. Rolfe Daus Peterson and Carl L. Palmer. Politics and the Life Sciences, Volume 36, Issue 2, Fall 2017 , pp. 3-16. https://doi.org/10.1017/pls.2017.18
Abstract: Physical attractiveness is an important social factor in our daily interactions. Scholars in social psychology provide evidence that attractiveness stereotypes and the “halo effect” are prominent in affecting the traits we attribute to others. However, the interest in attractiveness has not directly filtered down to questions of political behavior beyond candidates and elites. Utilizing measures of attractiveness across multiple surveys, we examine the relationship between attractiveness and political beliefs. Controlling for socioeconomic status, we find that more attractive individuals are more likely to report higher levels of political efficacy, identify as conservative, and identify as Republican. These findings suggest an additional mechanism for political socialization that has further implications for understanding how the body intertwines with the social nature of politics.

However, the interest in attractiveness has not directly filtered down to questions of political behavior beyond candidates and elites. Utilizing measures of attractiveness across multiple surveys, we examine the relationship between attractiveness and political beliefs. Controlling for socioeconomic status, we find that more attractive individuals are more likely to report higher levels of political efficacy, identify as conservative, and identify as Republican. These findings suggest an additional mechanism for political socialization that has further implications for understanding how the body intertwines with the social nature of politics.
Intelligence and Offending: A Longitudinal Examination of the Differential Detection Hypothesis
Schwartz, Joseph A, and Kevin M Beaver. 2018. “Intelligence and Offending: A Longitudinal Examination of the Differential Detection Hypothesis”. PsyArXiv. January 23. psyarxiv.com/z8wmg
Abstract: A well-developed literature has documented a negative and robust association between IQ and criminal behavior. At the same time, relatively little is known about the factors that ultimately contribute to the association, with the existing research revealing two possibilities. First, in line with population heterogeneity, IQ scores may tap internalized sources of influence that collectively increase underlying levels of criminality. Second, the differential detection hypothesis indicates that lower scores on IQ tests do not necessarily result in increases in criminal behavior, but rather result in a greater likelihood of coming into contact with law enforcement. The current study analyzed data from the Pathways to Desistance Study (N = 1,354) to examine the merits of these explanations. The results of survival analysis, which included controls for a time-stable, trait-based measure of criminality (measured using a latent trait-state-occasion approach) and other covariates, revealed a small, but negative and statistically significant, association between IQ and arrest, providing support for the differential detection hypothesis. Implications for future research and theoretical development are provided along with a discussion of the further incorporation of the concept of intelligence into the criminological literature.

Audio and video increase awareness of incivility cues as well as participants’ evaluations of negative, emotional, and entertaining tone
Platforms for Incivility: Examining Perceptions Across Different Media Formats. Emily Sydnor. Political Communication, Volume 35, 2018 - Issue 1: Studying Politics Across Media. Pages 97-116. https://doi.org/10.1080/10584609.2017.1355857
Abstract: This article investigates how the mix of attributes present across different media shapes perceptions of incivility. I argue that certain modalities, particularly the channel and structure of a media platform, facilitate the perception of media as more uncivil even if the content is kept the same. To test this argument, I conduct two survey experiments in which participants are randomly assigned to treatments in which the substantive content and text remains the same but is packaged to mimic different media types. Generally, audio and video increase awareness of incivility cues as well as participants’ evaluations of negative, emotional, and entertaining tone. There are also differences in the extent to which individuals notice incivility on Twitter than on other text-based media platforms. The social media platform is also particularly entertaining in comparison to the other platforms studied. This article demonstrates that media attributes interact to shape our understanding and identification of uncivil language. Furthermore, it suggests that more attention should be focused on identifying the different sets of characteristics that make incivility more or less likely or salient in political media.

I found consistently higher memory for unattractive over both attractive and medium-attractive faces
The influence of facial attractiveness on recognition memory: Behavioural findings and electrophysiological evidence. Carolin S. Altmann, Dissertation zur Erlangung des akademischen Grades doctor philosophiae (Dr. phil.), Friedrich-Schiller-Universität, Jena.
This thesis is based on a series of experiments that aimed to better understand the influence attractiveness has on memory while always controlling for perceived distinctiveness. First, I created a large stimulus pool of 1100 faces and obtained ratings on a number of relevant dimensions (see sections 2.1 and 3). In the first study, I investigated if memory for faces increased linearly with increasing attractiveness or whether this relationship was more complex (see section 3). In the second study, I investigated the combined influence of attractiveness and gender on recognition memory to competitively test predictions of perceptual expertise, social cognition, and alternative accounts (see section 4). In the third study, l, I investigated encoding-related neural correlates of the attractiveness effect on memory at retrieval (see section 5) whereas the first two experiments focused on ERP memory effects during retrieval.
Taken together, I found consistently higher memory for unattractive over both attractive and medium-attractive faces. Further, medium-attractive faces were significantly less well remembered than attractive faces in studies 1 and 2, and numerically in study 3. This difference disappeared when emotional relevance, i.e. valence and arousal, was taken into account. Inspection of ERPs showed increased P2 amplitudes for medium-attractive faces at retrieval in studies 1 and 2, and a pronounced Dm effect in this component in study 3. Thus, the attractiveness effect on face recognition memory seems already rooted in evolved, i.e. more refined and higher-level, perceptual processing of faces reflected in the P2. Overarchingly, these findings argue in favour of perceptual accounts, i.e. representational clustering (see sections 1.6.1 and 6.2.4), as both attractive and medium-attractive faces are supposedly more densely clustered in participants’ mental storage. The current data further indicate some contribution of emotional relevance. As no significant influence of face or participant gender was observed, there was also no compelling evidence for accounts of social cognition.

Giving advice enhances the adviser’s sense of power because it gives the adviser perceived influence over others’ actions; people with a high tendency to seek power are more likely to give advice than those with a low tendency
Advice Giving: A Subtle Pathway to Power. Michael Schaerer et al. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167217746341
Abstract: We propose that interpersonal behaviors can activate feelings of power, and we examine this idea in the context of advice giving. Specifically, we show (a) that advice giving is an interpersonal behavior that enhances individuals’ sense of power and (b) that those who seek power are motivated to engage in advice giving. Four studies, including two experiments (N = 290, N = 188), an organization-based field study (N = 94), and a negotiation simulation (N = 124), demonstrate that giving advice enhances the adviser’s sense of power because it gives the adviser perceived influence over others’ actions. Two of our studies further demonstrate that people with a high tendency to seek power are more likely to give advice than those with a low tendency. This research establishes advice giving as a subtle route to a sense of power, shows that the desire to feel powerful motivates advice giving, and highlights the dynamic interplay between power and advice.

The Effect of Germ Movement on the Construal of Mental States in Germs: The Moderating Role of Contamination Fear
The Effect of Germ Movement on the Construal of Mental States in Germs: The Moderating Role of Contamination Fear. John H. Riskind, Dylan K. Richards. Cognitive Therapy and Research, February 2018, Volume 42, Issue 1, pp 36–47. https://link.springer.com/article/10.1007/s10608-017-9877-2
Abstract: In two studies, we examined a novel relationship between movement and anthropomorphism—the attribution of human characteristics to nonhuman agents—in relation to germs. Furthermore, we examined whether individual differences in contamination fear and disgust proneness moderated the effect of movement on the tendency to anthropomorphize germs. Following an initial study that demonstrated associations between imagined germ movement, contamination fear, and the attribution of malevolent intentions to germs, we conducted a second study that experimentally manipulated germ movement with a brief film clip of magnified germs. The results of the second study showed that the experimental manipulation of germ movement increased attributions of malevolent intentions to germs and enhanced the tendencies of individuals with higher levels of contamination fear to attribute some general human characteristics to germs (i.e., intentions, feelings). These findings suggest that the attribution of malevolent intentions to germs may be a cognitive distortion that contributes to the maintenance of contamination fear, which may afford a novel treatment target. Perceived movement may serve as an antecedent to the attribution of malevolent intentions to germs and thus exacerbate the tendency to make these attributions.

Decreases in extraversion are attenuated for individuals categorized as light-to-moderate drinkers, while decreases in conscientiousness were accentuated by having experienced alcohol dependence symptoms
Luchetti, M., Terracciano, A., Stephan, Y. and Sutin, A. R. (), Alcohol use and personality change in middle and older adulthood: Findings from the Health and Retirement Study. Journal of Personality. Accepted Author Manuscript. doi:10.1111/jopy.12371
Abstract
Objective: Personality is known to predict alcohol consumption but how alcohol use is related to personality change is less clear, especially at older ages. The present study examined the effects of level of alcohol consumption and history of dependence on change in the five-factor model personality traits in a national cohort of Americans aged over 50.
Method: Over 10,000 adults who participated in 2006-08 waves of the Health and Retirement Study reported on personality and alcohol use and were followed over 4 years.
Results: Latent difference score models indicated decreases in extraversion to be attenuated for individuals categorized as light-to-moderate drinkers at baseline, while decreases in conscientiousness were accentuated by having experienced alcohol dependence symptoms. Moreover, personality difference scores correlated with changes in the amount of alcohol consumed at follow-up.
Conclusions: The findings suggest that patterns of alcohol consumption are associated with changes in personality across the second half of the lifespan.

Introduction of Uber ride-sharing service is associated with lower DUI and fatal accident rates. For some specifications, there are also less arrests for assault and disorderly conduct. There is an increase in vehicle thefts
Dills, A. K. and Mulholland, S. E. (2018), Ride-Sharing, Fatal Crashes, and Crime. Southern Economic Journal. doi:10.1002/soej.12255
Abstract: The advent of smart-phone based, ride-sharing applications has revolutionized the vehicle for hire market. Advocates point to the ease of use, lower prices, and shorter wait times compared to hailing a taxi or prearranging limousine service. Others argue that proper government oversight is necessary to protect ride-share passengers from driver error or vehicle parts failures and violence from unlicensed strangers. Using U.S. county-level data from 2007 through 2015, we investigate whether the introduction of the ride-sharing service Uber is associated with changes in fatal vehicle crashes and crime. We find that Uber's entry lowers the rate of DUIs and fatal accidents. For some specifications, we also find declines in arrests for assault and disorderly conduct. Conversely, we observe an increase in vehicle thefts.

We argue that anger likely plays a major role in motivating individuals to engage in the biased assimilation of political information—an evaluative bias in favor of information that bolsters one's views and against information that undercuts them
Suhay, E. and Erisen, C. (2018), The Role of Anger in the Biased Assimilation of Political Information. Political Psychology. doi:10.1111/pops.12463
Abstract: Political psychologists have established that politically motivated reasoning is a common phenomenon; however, the field knows comparatively less about the psychological mechanisms that drive it. Drawing on advances in the understanding of the relevance of emotion to political reasoning and behavior, we argue that anger likely plays a major role in motivating individuals to engage in the biased assimilation of political information—an evaluative bias in favor of information that bolsters one's views and against information that undercuts them. We test this proposition with two online studies, the second of which includes a quasi-representative sample of Americans. The studies support our expectations. Individuals felt more negative emotions toward arguments that undermined their attitudes and positive emotions toward arguments that confirmed them; however, anger was nearly alone in fueling biased reactions to issue arguments.
