US, UK, Germany: Workers feel as secure as they ever have in the last thirty years, partly because job insecurity is very cyclical and (pre-COVID) unemployment rates very low, but there is also no clear underlying trend towards increased subjective measures of job insecurity

Subjective Job Insecurity and the Rise of the Precariat: Evidence from the United Kingdom, Germany, and the United States. Alan Manning, Graham Mazeine. The Review of Economics and Statistics 1–45. May 12 2022. https://doi.org/10.1162/rest_a_01196

Abstract: There is a widespread belief that work is less secure than in the past, that an increasing share of workers are part of the “pprecariat”. It is hard to find much evidence for this in objective measures of job security, but perhaps subjective measures show different trends. This paper shows that in the US, UK, and Germany workers feel as secure as they ever have in the last thirty years. This is partly because job insecurity is very cyclical and (pre-COVID) unemployment rates very low, but there is also no clear underlying trend towards increased subjective measures of job insecurity. This conclusion seems robust to controlling for the changing mix of the labor force, and is true for specific sub-sets of workers.

Dark Triad traits accelerate psychological violence toward romantic partners

Do the Dark Triad and psychological intimate partner violence mutually reinforce each other? An examination from a four-wave longitudinal study. Yuji Kanemasa, Yuki Miyagawa, Takashi Arai. Personality and Individual Differences, Volume 196, October 2022, 111714. https://doi.org/10.1016/j.paid.2022.111714

Abstract: Although cross-sectional research showed a correlation between the Dark Triad and intimate partner violence (IPV), it was unclear whether the Dark Triad facilitated violence toward partners or whether violent acts fostered the dark personality traits. We aimed to statistically clarify the causal relationships between the Dark Triad traits and psychological IPV perpetration in romantic relationships. We conducted a longitudinal study every four months for one year across four waves in a sample of individuals who were currently in romantic relationships. A total of 1392 individuals (Mage = 29.73, SDage = 5.92) who dated the same partners throughout completed the four waves of surveys that measured the Dark Triad traits, psychological IPV, and demographic variables. Cross-lagged panel models revealed consistent patterns in the associations between each of the Dark Triad traits and psychological IPV perpetration throughout the four waves. Machiavellianism and psychological IPV perpetration increased each other. Psychological IPV perpetration reinforced the tendency for psychopathy, but not vice versa. Narcissism promoted future psychological IPV perpetration, but not vice versa. Our study illustrates how the Dark Triad traits accelerate psychological violence toward romantic partners and how such violence fosters the dark side of personality.

Women are less accepting than men of higher-ranked same-sex individuals; more generally however, women and men prefer male bosses

Human Females as a Dispersal-Egalitarian Species: A Hypothesis about Women and Status. Joyce F. Benenson. Adaptive Human Behavior and Physiology, May 21 2022. https://link.springer.com/article/10.1007/s40750-022-00191-x

Abstract

Objectives: A paradox exists in research on girls and women. On the one hand, they behave in a more egalitarian fashion than their male counterparts. On the other hand, status increases their own and their children’s survival.

Methods: Evidence from non-human primates can help reconcile these findings. In species that do not reside with female kin for life, females are relatively egalitarian and individualistic. They typically do not cooperate or engage in direct competition and exhibit little tolerance for status differentials.

Results and Conclusions: Women follow this pattern. While a husband’s status and her female relatives’ support enhance a woman’s status and reproductive success, her own actions too influence her access to resources and allies. Evidence on girls’ and women’s same-sex competition and quests for status supports the hypothesis that human females inhabit dispersal-egalitarian communities in which competition is avoided, an egalitarian ethos prevails, competitive behavior is disguised, and status differentials are not tolerated.

Personality stability increases mostly until 25 yo; emotional stability increased consistently and more substantially across the lifespan than currently believed

Bleidorn, Wiebke, Ted Schwaba, Anqing Zheng, Christopher J. Hopwood, Susana Sosa, Brent Roberts, and Daniel A. Briley. 2022. “Personality Stability and Change: A Meta-analysis of Longitudinal Studies.” PsyArXiv. May 20. doi:10.31234/osf.io/eq5d6

Abstract: Past research syntheses provided evidence that personality traits are both stable and changeable throughout the lifespan. However, early meta-analytic estimates were constrained by a relatively small universe of longitudinal studies, many of which tracked personality traits in small samples over moderate time periods using measures that were only loosely related to contemporary trait models such as the Big Five. Since then, hundreds of new studies have emerged allowing for more precise estimates of personality trait stability and change across the lifespan. Here, we updated and extended previous research syntheses on personality trait development by synthesizing novel longitudinal data on rank-order stability (total k = 189, total N = 178,503) and mean-level change (total k = 276, N = 242,542) from studies published after January 1st 2005. Consistent with earlier meta-analytic findings, the rank-order stability of personality traits increased significantly throughout early life before reaching a plateau in young adulthood. These increases in stability coincide with mean-level changes in the direction of greater maturity. In contrast to previous findings, we found little evidence for increasing rank-order stabilities after age 25. Moreover, cumulative mean-level trait changes across the lifespan were slightly smaller than previously estimated. Emotional stability, however, increased consistently and more substantially across the lifespan than previously found. Moderator analyses indicated that narrow facet-level and maladaptive trait measures were less stable than broader domain and adaptive trait measures. Overall, the present findings draw a more precise picture of the lifespan development of personality traits and highlight important gaps in the personality development literature.


In the dating market, people compete ferociously for mates with qualities that do not increase one’s chances of romantic happiness

Adapted from Don't Trust Your Gut: Using Data to Get What You Really Want in Life, by Seth Stephens-Davidowitz. Wired, May 2022. https://www.wired.com/story/data-marriage-behavior-love-psychology-romance/



Whom shoud you marry?



This may be the most consequential decision of a person’s life. The billionaire investor Warren Buffett certainly thinks so. He calls whom you marry “the most important decision that you make.”



[...]



She recruited a large number of scientists who had collected data on relationships—her team ended up including 85 other scientists—and was able to build a dataset of 11,196 heterosexual couples.



The size of the dataset was impressive. So was the information contained in it. For each couple, Joel and her team of researchers had measures of how happy each partner reported being in their relationship. And they had data on just about anything you could think to measure about the two people in that relationship.



The researchers had data on:



demographics (e.g., age, education, income, and race)


physical appearance (e.g., How attractive did other people rate each partner?)


sexual tastes (e.g., How frequently did each partner want sex? How freaky did they want that sex to be?)


interests and hobbies


mental and physical health


values (e.g., their views on politics, relationships, and child-rearing)



and much, much more.



Further, Joel and her team didn’t just have more data than everybody else in the field. They had better statistical methods. Joel and some of the other researchers had mastered machine learning, a subset of artificial intelligence that allows contemporary scholars to detect subtle patterns in large mounds of data. One might call Joel’s project the AI Marriage, as it was among the first studies to utilize these advanced techniques to try to predict relationship happiness.



After building her team and collecting and analyzing the data, Joel was ready to present the results—results of perhaps the most exciting project in the history of relationship science.



So, can Samantha Joel—teaming up with 85 of the world’s most renowned scientists, combining data from 43 studies, mining hundreds of variables collected from more than 10,000, and utilizing state-of-the-art machine learning models—help people pick better romantic partners?



No.



The number one—and most surprising—lesson in the data, Samantha Joel told me in a Zoom interview, is “how unpredictable relationships seem to be.” Joel and her coauthors found that the demographics, preferences, and values of two people had surprisingly little power in predicting whether those two people were happy in a romantic relationship.



And there you have it, folks. Ask AI to figure out whether a set of two human beings can build a happy life together and it is just as clueless as the rest of us.



Well... that sure seems like a letdown. Does data science really have nothing to offer us in picking a romantic partner, perhaps the most important decision that we will face in life?



Not quite. In truth, there are important lessons in Joel and her coauthors’ machine learning project, even if computers’ ability to predict romantic success is worse than many of us might have guessed.



For one, while Joel and her team found that the power of all the variables that they had collected to predict a couple’s happiness was surprisingly small, they did find a few variables in a mate that at least slightly increase the odds you will be happy with them. More important, the surprising difficulty in predicting romantic success has counterintuitive implications for how we should pick romantic partners.



Think about it. Many people certainly believe that many of the variables that Joel and her team studied are important in picking a romantic partner. They compete ferociously for partners with certain traits, assuming that these traits will make them happy. If, on average, as Joel and her coauthors found, many of the traits that are most competed for in the dating market do not correlate with romantic happiness, this suggests that many people are dating wrong.



[...]



If I had to sum up, in one sentence, the most important finding in the field of relationship science, thanks to these Big Data studies, it would be something like this (call it the First Law of Love): In the dating market, people compete ferociously for mates with qualities that do not increase one’s chances of romantic happiness.

In mammalian societies... How reproductive control promotes social control

The eco-evolutionary landscape of power relationships between males and females. Eve Davidian et al. Trends in Ecology & Evolution, May 18, 2022. https://doi.org/10.1016/j.tree.2022.04.004

Highlights

. Inequality in the degree of control (or ‘power’) that members of one sex exert over members of the other sex is a pervasive characteristic of mammalian societies, including our own.

. The study of the drivers of male–female power relationships has been impeded by methodological limitations and a lack of conceptual embedding in theories of sexual conflict, sexual selection and social evolution.

. Recent evidence challenges long-standing views by showing that (i) power ranges along a continuum from strictly male- to strictly female-dominated animal societies and (ii) intersexual power relationships are not fixed attributes of species.

. Here we break with dichotomist and static approaches to adopt a dynamic, theory-driven framework that provides a better understanding of the power struggles between the sexes, and how these relate to the social and mating system of a species.

Abstract: In animal societies, control over resources and reproduction is often biased towards one sex. Yet, the ecological and evolutionary underpinnings of male–female power asymmetries remain poorly understood. We outline a comprehensive framework to quantify and predict the dynamics of male–female power relationships within and across mammalian species. We show that male–female power relationships are more nuanced and flexible than previously acknowledged. We then propose that enhanced reproductive control over when and with whom to mate predicts social empowerment across ecological and evolutionary contexts. The framework explains distinct pathways to sex-biased power: coercion and male-biased dimorphism constitute a co-evolutionary highway to male power, whereas female power emerges through multiple physiological, morphological, behavioural, and socioecological pathways.

How reproductive control promotes social control

Here we propose that the degree of male and female reproductive control determines whether and how members of each sex can empower themselves socially, with respect to access to nonreproductive resources. We further illustrate how the mechanism by which power emerges may influence its durability.

 Coercion: an evolutionary highway to male power

Male coercive reproductive control is facilitated by large male-biased sexual dimorphism in size and weaponry, which is typical of contest-based mating systems, and includes most polygynous and some polygynandrous societies [,,] (Figure 1). In these systems, males often extend their use of coercion to dominate females when competing over nonreproductive resources. Large males may further reinforce intersexual asymmetries in coercive potential and limit female empowerment by controlling their social environment and preventing them from recruiting social allies (Box 2). The tight association between the pervasive use of coercion by males and male-biased sexual dimorphism likely emerges from a co-evolutionary feedback with the mating system (Figure 2). When males gain reproductive pay-offs from aggressively monopolising females against competitors, this will often (i) promote contest-based competition between males; (ii) subsequently drive the evolution of male-biased sexual dimorphism [,], which will (iii) promote male coercive reproductive control over females; and (iv) drive male social empowerment and dominance over females [,,]. This will (v) ultimately close the loop by strengthening male reproductive control over females [,,,]. When female resistance strategies fail to prevent or disrupt this potent self-reinforcing loop, it may catalyse the emergence and maintenance of male-biased power over evolutionary times. This likely explains why males often exert both high reproductive and social control over females in contest-based mating systems (Figure 1), and why contest-based systems are widespread among mammals. In addition, female strategies may sometimes reinforce rather than disrupt the loop favouring male power. For example, where males already have high reproductive control and females cannot mate promiscuously to dilute paternity, they may instead concentrate paternity to seek paternal protection in response to infanticidal threats []. Such paternity concentration strategies may contribute to locking females into male-dominated societies.

Figure 2Eco-evolutionary pathways to male and female empowerment in mammals.

 Why the coercive pathway is not the females’ way

A similar coercive co-evolutionary pathway is unlikely to drive female social empowerment because mammalian species in which females concurrently exhibit contest-based intrasexual competition to monopolise access to multiple males and larger body sizes are currently unreported [,]. In some species, reproductive competition may be most intense among females; yet, contrary to what would be expected for this co-evolutionary pathway, these species either exhibit sexual monomorphism, as in the polyandrous moustached tamarins (Saguinus mystax) [] and cooperatively breeding meerkats [] (Figure 1A), or male-biased size dimorphism as in Damaraland mole rats (Fukomys damarensis) []. This apparent paradox probably reflects inherent differences in the life history and modality of intrasexual competition in females and males []. Female mammals often compete using subtle forms of coercion – for example, using threats and agonistic signals – which do not select for increased body size and weaponry. There are at least three reasons for this: first, theory predicts avoidance of overt aggression for the sex that faces highest costs of offspring production []; second, the incentive for females to engage in physical contest may be low because sharing resources is often less costly for females than for males; third, mammalian females are usually philopatric and thus predominantly compete with close female kin, with whom they may avoid engaging in costly contests []. These insights emphasise key differences in the pathways to female and male power (Figure 2), in particular that a large body size and coercion are not prerequisites for female empowerment.

 Female social empowerment from leverage based on sex

When females retain some reproductive control – usually in species with moderate sexual size dimorphism as in monogamouspolyandrous, and scramble-based polygynandrous species (Figure 1) – they can trade copulations for resources or services that males can provide, such as protection for themselves or their offspring against conspecifics or predators. Yet, such leverage is usually restricted to periods of female sexual receptivity and thereby only confer short-term social empowerment to females, as in some mouse lemurs (Microcebus spp.) where female social control over males is more pronounced during the breeding season [,]. Leverage-based power may therefore explain female social empowerment over males in species where males are nonpermanent residents and join groups only during the mating season, as in rock hyraxes []. In species living in permanent groups where males and females maintain long-term, differentiated social relationships, females can extend their leverage beyond the receptive period. This strategy may durably promote cooperative behaviour or inhibit aggression from males through mating markets, as in long-tailed macaques (Macaca fascicularis) [] and Guinea baboons (Papio papio) []. Leverage can then represent a potent source of social control that may, even under male-biased dimorphism, allow females to manipulate the social rank of subordinate males, as in vervet monkeys [], or to influence male social and competitive relationships, as in bonobos (Box 3). Similar to males, but through a different mechanism, increased social control by females may subsequently reinforce female reproductive control by facilitating their resistance to unwanted solicitations in a positive feedback loop (Figure 2).

 Female social empowerment from mate choice

When female reproductive control enables them to exercise precopulatory mate choice, they may select male traits (e.g., social deference, cooperative personalities, or a smaller body size) that may, over evolutionary time, increase female social control in a process described by the ‘docile male’ hypothesis []. In bonobos, the related ‘self-domestication’ hypothesis posits that selection for nonaggressive males, which may partly result from female choice, has contributed to the contrasts in morphology, physiology, behaviour, and cognition between male bonobos and chimpanzees (Pan troglodytes) []. Empirical evidence of female mate choice for such male traits is scarce in mammals, however []. Female preferences for males with whom they are socially bonded have been reported [,], but may reflect leverage rather than choice for male traits that are relevant to intersexual power. Alternatively, female mate choice can promote intersexual power asymmetries indirectly. For example, in spotted hyenas, female reproductive control and mate preferences drive male dispersal [], which decreases the number of social allies that males can recruit and thus reduces male social control [].

Sex and Sexual Orientation Differences in Sexuality and Mate Choice Criteria. Bogdan Kostic & John E. Scofield. Archives of Sexual Behavior, May 19 2022. https://link.springer.com/article/10.1007/s10508-021-02280-6


Abstract: Previous research has documented several reliable differences between men and women in terms of mate preferences regarding age, physical appearance, financial prospects, and more. However, most of the research has been on heterosexual populations. The current study attempted to further explore those differences in non-heterosexual populations. The project was part replication regarding heterosexual populations and part exploratory regarding non-heterosexual populations. The sample contained 3298 participants, including 1863 males (1675 gynephiles, 56 androphiles, 132 bisexuals) and 1435 females (1037 androphiles, 33 gynephiles, 365 bisexuals). Participants responded to questions about mate preferences in terms of good financial prospects, good looks, chastity, ambition/industriousness, youth/age, uncommitted sex, visual sexual stimuli, status, physical attractiveness, jealousy, and interest in short- versus long-term mating. Results replicated typical sex differences between heterosexual men and women in all measures we analyzed. We also found several instances when bisexual respondents were more different from heterosexual respondents than homosexual respondents (specifically regarding interest in uncommitted sex, the importance of chastity, and interest in short-term mating). Despite limitations in data collection, the results demonstrate that homosexual and bisexual individuals do not always form a heterogenous group.

Unlike doctors and surgeons, psychologists are more likely to present the left cheek on their professional photographs, perhaps signalling (intuitively) their empathy

Putting your best face forward: Posing biases in psychologists’ online portraits. Ven Yi Hew & Annukka K. Lindell. Laterality. Asymmetries of Brain, Behaviour, and Cognition. May 19 2022. https://doi.org/10.1080/1357650X.2022.2077745

Abstract: When posing for portraits the position you adopt influences perceptions. As the left hemiface (controlled by the emotion-dominant right hemisphere) expresses emotion more intensely, left cheek portraits communicate stronger emotion than right cheek portraits. This phenomenon influences perceptions of both emotional expressivity and professional specialisation: while left cheek portraits emphasise emotion, right cheek portraits appear more scientific. When professionals upload photographs online to promote their services, the cheek shown consequently influences perceptions. Given the importance of empathy in establishing a therapeutic alliance, theoretically psychologists would benefit from choosing left cheek portraits to enhance their perceived emotionality. The present study thus examined psychologists’ posing biases in photographs uploaded to online “Find a Psychologist” resources. Images (N = 1230) of psychologists were drawn from professional “Find a Psychologist” online databases, and coded for gender, portrait type and cheek shown. Results confirmed that psychologists show a left cheek bias, irrespective of gender and across portrait types (upper body, full body). This distinguishes psychologists from doctors and surgeons: past research reports no cheek bias in photos uploaded to “Find a Doctor” websites. The current findings suggest that psychologists may intuitively select left cheek images to enhance the communication of empathy to potential clients.

The strongest, and most reliable, predictor of perceived danger of misinformation is the perception that others are more vulnerable to misinformation than the self; believing that societal problems have simple solutions/clear causes is consistently, weakly, associated

Altay, Sacha, and Alberto Acerbi. 2022. “Misinformation Is a Threat Because (other) People Are Gullible.” PsyArXiv. May 20. doi:10.31234/osf.io/n4qrj

Abstract: Alarmist narratives about the flow of misinformation and its negative consequences have gained traction in recent years. If these fears are to some extent warranted, the scientific literature suggests that many of them are exaggerated. Why are overly alarmist narratives about misinformation so popular? In two pre-registered experiments (N = 600, UK), replicated in the US (N = 601), we investigated the psychological factors associated with perceived danger of misinformation and how it contributes to the popularity of alarmist narratives on misinformation. We find that the strongest, and most reliable, predictor of perceived danger of misinformation is the third-person effect (i.e., the perception that others are more vulnerable to misinformation than the self) and, in particular, the belief that ‘distant’ others (as opposed to family and friends) are vulnerable to misinformation. The belief that societal problems have simple solutions and clear causes was consistently, but weakly, associated with perceived danger of online misinformation. Other factors, like negative attitudes towards new technologies and higher sensitivity to threats, were inconsistently, and weakly, associated with perceived danger of online misinformation. Finally, we found that participants who report being more worried about misinformation are more willing to like and share alarmist narratives on misinformation. Our findings suggest that alarmist narratives on misinformation tap into our tendency to view other people as gullible.



People spontaneously looked more and for longer at the sexually provocative images when their eyes were camouflaged by sunglasses (which we surreptitiously monitored)

De-evolving human eyes: The effect of eye camouflage on human attention. Veronica Dudarev, Manlu Liu, Alan Kingstone. Cognition, Volume 225, August 2022, 105136. https://doi.org/10.1016/j.cognition.2022.105136

Abstract: Eyes are communicative. But what happens when eyes are camouflaged? In the present study, while either wearing sunglasses (that camouflaged the eyes) or clear glasses, participants were presented with sexually provocative and neutral images, which they viewed in the presence of another person who they knew was observing their eyes. Unbeknownst to the participants, however, we also surreptitiously monitored and recorded their eye gaze in both conditions. People spontaneously looked more and for longer at the sexually provocative images when their eyes were camouflaged by sunglasses. This finding provides convergent evidence for the proposal that covert attention operates in service of overt social attention, and suggests that decoupling overt and covert attention is much more prevalent than previously assumed. In doing so it also sheds light on the relation between the evolution of human eye morphology and systems of attention.

Consistent with beauty-blind admissions, alumni's beauty is uncorrelated with the rank of the school they attended in China; in the US, White men who attended high-ranked schools are better looking, especially attendees of private schools

The college admissions contribution to the labor market beauty premium. David Ong. Contemporary Economic Policy, April 18 2022. https://doi.org/10.1111/coep.12570

Abstract: We investigate the contribution of college admissions to the labor market beauty premium. We sampled 1800 social media profiles of students from universities ranked from 1 to 200 in China and the US. Chinese universities use standardized test scores for admissions. US universities use also extracurricular activities. Consistent with beauty-blind admissions, alumni's beauty is uncorrelated with the rank of the school they attended in China. In the US, White men who attended high-ranked schools are better looking, especially attendees of private schools. A one percentage point increase in beauty rank corresponds to a half-point increase in the school rank.

For the majority of Americans, partisanship is either equally positive and negative or more positive than negative

Negative partisanship is not more prevalent than positive partisanship. Amber Hye-Yon Lee, Yphtach Lelkes, Carlee B. Hawkins & Alexander G. Theodoridis. Nature Human Behaviour, May 19 2022. https://www.nature.com/articles/s41562-022-01348-0


Abstract: The dominant narrative among scholars and political pundits characterizes American partisanship as overwhelmingly negative, portraying citizens as more repelled by the opposing party than attached to their own party. To assess the valence of partisan identity, we use various measures collected from several new and existing nationally representative surveys and behavioural outcomes obtained from two experiments. Our findings consistently depart from the negative partisanship narrative. For the majority of Americans, partisanship is either equally positive and negative or more positive than negative. Only partisan leaners stand out as negative partisans. We pair these observational findings with experimental data that differentiate between positive group behaviour and negative group behaviour in the partisan context. We find that the behavioural manifestations of party identity similarly include both positive and negative biases in balance, reinforcing our conclusion that descriptions of partisanship as primarily negative are exaggerated.
