Female orgasm evolved as a mate-selection tool for females and promotes long-term, pair bonding but does not provide support for the hypothesis that it evolved as an indicator of male value

The Effect of Female Orgasm Frequency on Female Mate Selection: A Test of Two Hypotheses. Patrick J. Nebl, Anne K. Gordon. Evolutionary Psychology, March 9, 2022. https://doi.org/10.1177/14747049221083536

Abstract: Female orgasm has been a mystery that psychologists have been attempting to understand for decades. Many have contended that female orgasm is a functionless by-product of male orgasm, while others have argued that female orgasm may be an adaptation in its own right, offering several adaptationist accounts of female orgasm. In the current research, we tested predictions derived from two hypotheses regarding adaptive functions of female orgasm: female orgasm indicates partner mate value or female orgasm promotes long-term, pair bonding. 199 female undergraduates participated in an experiment where they imagined themselves as a member of a romantic relationship provided in a scenario. Within these scenarios, the relationships varied between either short- or long-term and the frequency that the female experienced orgasm during intercourse varied between never, occasionally, and almost always. Participants answered questions regarding relationship satisfaction and perceptions of the fictional relationship. A series of analysis of variance (ANOVAs) indicated that females assigned to conditions of experiencing more frequent orgasms reported greater relationship satisfaction, across both short- and long-term relationships. The relationship between female orgasm frequency and relationship satisfaction was fully mediated by the female's perceived love for her hypothetical partner but not by perceptions of her hypothetical partner's commitment. Taken together, this study provides preliminary support for the hypothesis that female orgasm evolved as a mate-selection tool for females and promotes long-term, pair bonding but does not provide support for the hypothesis that female orgasm evolved as an indicator of male value.

According to the “Mr. Right” hypothesis of mate choice the frequency of female orgasm acts as an indicator that helps females evaluate males during short-term mating contexts as potential long-term mates. If this hypothesis is valid then when evaluating a male's care and commitment toward her, females should be sensitive to information about a man's ability to bring her to orgasm.

According to the long-term pair bonding hypothesis of mate choice, female orgasm promotes female attachment to a male with whom she experiences orgasm, promoting long-term relationships. If this hypothesis is valid then a female's feelings of attachment and closeness to a mate should be affected by experiencing orgasm with the mate in long-term contexts.

In this study, female participants read a scenario about a relationship between a male and a female and imagined themselves as the female in the relationship. Within these scenarios two independent variables were manipulated—female orgasm frequency and relationship context. The female's frequency of orgasm varied among three levels--never, occasionally, and almost always. The relationship context varied between two levels--short-term or long-term. The main dependent measures included female's perceptions of the relationship's quality, including her degree of relationship satisfaction and commitment.

  • Prediction 1: Based on the mate-choice hypothesis, we expected that females, regardless of context, who role-played experiencing higher frequencies of orgasm would report greater relationship satisfaction.

  • Prediction 2: If the Mr. Right hypothesis of mate choice is correct, we expected this relationship between female orgasm frequency and relationship satisfaction to be at least partially mediated by females’ perceptions of their partner's commitment.

  • Prediction 3: If the long-term pair bonding hypothesis of mate choice is correct, we expected this relationship between female orgasm frequency and relationship satisfaction to be at least partially mediated by love for her partner.

Girls score higher in tested emotional intel, but boys tend to overestimate their performance, girls underestimate; opposite tendencies in the two sexes may amplify the distances between the emotional world of boys and girls, probably increasing the gender conflicts

Sex differences in emotional and meta-emotional intelligence in pre-adolescents and adolescents. Antonella D'Amico, Alessandro Geraci. Acta Psychologica, Volume 227, July 2022, 103594. https://doi.org/10.1016/j.actpsy.2022.103594

Highlights

• Girls show higher levels of ability EI than boys.

• Boys report higher levels of self-reported EI than girls.

• Boys tend to overestimate their emotional abilities compared to girls.

• Girls tend to underestimate their emotional abilities compared to boys.

• Girls report higher scores than boys in meta-emotional beliefs.

Abstract: The study focuses on sex differences in emotional and meta-emotional intelligence in a sample of 355 pre-adolescents and 164 adolescents. Emotional and meta-emotional intelligence were measured using the multi-trait multi-method IE-ACCME test, allowing to define individuals' profiles of ability EI, emotional self-concept, meta-emotional knowledge, meta-emotional ability in self-evaluation and meta-emotional beliefs. Meta-emotional dimensions refer to the awareness of individuals about their emotional abilities and to their beliefs about the functioning of emotions in everyday life. Results demonstrated that girls scored better than boys in ability-EI, in particular in adolescents' group, whereas boys reported higher score than girls in emotional self-concept in both groups of age. Result about meta-emotional knowledge and meta-emotional ability in self-evaluation revealed that boys systematically overestimate their emotional abilities whereas girls, particularly in the adolescent group, tend to underestimate them. Finally, in both age groups, girls scored higher than males in metaemotional beliefs. The adoption of the meta-emotional intelligence framework may help to explain the discordances about sex differences found in previous studies using self-report vs. performance measures of EI. Moreover, it may contribute to shed light on the nature-nurture debate and on the role of meta-emotional variables for explaining sex differences in EI.

4. Discussion

Our results demonstrate that there are many differences in girls' and boys' emotional and meta-emotional intelligence and that they are also influenced by age. Even if effect sizes are small, these differences are quite systematic, and we consider them noteworthy. Consistently with previous literature (Curci & D'Amico, 2010Cabello et al., 2016Day & Carroll, 2004Fernández-Berrocal et al., 2012Gutiérrez-Cobo et al., 2016Mayer et al., 1999Mayer et al., 2002Rivers et al., 2012) and with results already obtained by D'Amico (2013), girls score better than boys in ability-EI, and this is particularly evident in adolescent group. Results of emotional self-concept presents an opposite pattern, with boys reporting higher score than girls in both groups of age and in particular in the adolescent group and that is consistent with some studies (Khan & Bat, 2013Petrides & Furnham, 2000). Differently from what found by D'Amico (2013), there are no sex differences in self-rating about performance scale, indicating that when specific emotional tasks are considered, boys and girls are equally accurate in evaluating own performance. However, the age-group differences in self-rating about performance indicates that, independently from sex, adolescents are more parsimonious and critics in evaluate their own performance than pre-adolescents. This is consistent with results found by D'Amico (2013) in standardization sample, indicating that scores in self-rating about performance scale were negatively related to age (r = −0.152, p < .005). Girls show to own higher levels than boys in meta-emotional knowledge and boys systematically overestimate their emotional ability in everyday situation. This result is particularly evident among adolescents, where boy overestimate and girls underestimate their emotional abilities. In preadolescents' group, both sexes overestimate their abilities, but again the overestimation is higher for boys than for girls.

Concerning meta-emotional self-evaluation, independently by sex, pre-adolescents overestimate their performance in the ability test more than adolescents. However, there are sex and age differences in the direction of estimation: in pre-adolescents' group, both boys and girls tend to overestimate their performance, in adolescents' group, boys overestimate and girls underestimate their performance in the ability test. Finally, consistently with D'Amico (2013) we found that girls, in both age groups, scored higher than males in meta-emotional beliefs.

These results give rise again to the famous debate on nature and culture: by evidencing that the gap among sexes is higher in older than in younger group, they seem to give more weight to the culture pole. As previously argued, probably more and more over their life, culture might influence sex difference in term of the different styles that boys and girls adopt in sharing their emotion with others: typically, women compared to men feel the need to share their problem with others. These differences in what we could define as coping strategies (coping/isolation vs. coping/sharing) are likely to be at the basis of EI differences, especially in the case of measurement tools, like MSCEIT or IE-ACCME ability test, that are scored using the consensus criterion. As it is well known, the consensus criterion foresees that, in the ability test, the score assigned to each answer corresponds to the percentage of subjects who consider that answer valid. In other words, the “best” answers are those chosen by the largest number of subjects (i.e., the statistical mode). This procedure implies that people who obtain higher scores in emotional intelligence are not better than others but, rather, more similar to the rest of the population in the way they feel emotions. In this perspective, D'Amico (2018) defined ability EI as the ability of tuning with others or, in other word, to elaborate emotional experience like others. Thus, the tendency of little girls, teenagers and then women, to share their emotions with peers, and to listen to other's emotional issues, could generate their higher ability to tune with others, and it could be therefore the basis for this form of intelligence that is substantiated by feeling emotions like others and not differently from others. On the contrary, boys and men are probably less inclined to share emotions with others and to participate to personal and social building of emotional consensus. This could be an obstacle in developing adequate perspective taking abilities and the ability to tune with others.

As already said, the reason for many boys and men being less inclined to share their emotions with others probably stems from education and culture. Indeed, this style increases with age: on the other hand, almost in all cultures boys are expected, even as children, to be less sensitive than girls. Boys are expected not to cry, not to show or share emotions and to follow reason. On the contrary, girls are expected to follow feelings and to talk about emotions, and this expectation probably turn in a real lifelong “exercise of emotions”. However, our results seem to demonstrate that girls are not aware of their high emotional ability. Indeed, consistently with claims by Ciarrochi and colleagues, adolescent girls show an underestimation bias, since their emotional self-concept is lower than the abilities that they show in the ability test. A similar even if opposite pattern is showed by boys in adolescents' group, showing a stable overestimation bias in meta-emotional knowledge, with an emotional self-concept higher than the abilities that they show in the ability test. The same biases are observed also concerning the meta-emotional self-evaluation, with boys tending to overestimate and girls to underestimate their performance in the ability test.

In general, it seems that neither boys nor girls, with a very slight difference in pre-adolescents' and adolescents' groups, show a proper awareness of their emotional abilities. Indeed, both overestimation and underestimation reflect poor awareness of one's own emotions and may have negative effects on individual personal life. The overestimation of one's own emotional abilities might lead adolescents to copy with situation they are not able to manage; underestimation of their emotional abilities might lead them to avoid those situations that they could be able to front, reducing the experiences of success and in general their self-efficacy.

In our previous study on the relationship between emotional and meta-emotional intelligence and sociometric status (D'Amico & Geraci, 2021) we demonstrated that pre-adolescents with higher levels of ability EI, meta-emotional knowledge and meta-emotional self-evaluation are more accepted by others while those that overestimate their emotional abilities are more refused by peers. For this reason, we claimed that, for social relationships, the most “dangerous bias” in evaluating one's own emotional abilities is the overestimation. In this sense, based on our results, boys might be statistically more at risk for social rejection by peers than girl.

On the other hand, the tendency to underestimate may be likewise dangerous for girls. Indeed, we know from literature (Miao et al., 2016) that people perceiving themselves as emotional intelligent, tend to perceive general positive affect, such as feeling active, alert, and energetic at any given moment in time, whereas people who perceive themselves as poor in emotional intelligent tend to experience negative affect. Thus, on the basis of our results, girls might be statistically more at risk for negative affect and this could also help to explain, along with other neurobiological factors, the prevalence for anxiety (Jalnapurkar et al., 2018) and depression (Labaka et al., 2018) in females when compared to males. Overestimation and underestimation errors might be also a side effect of the different degree of importance that boys and girls give to emotions in everyday life. Our results in meta-emotional beliefs seem to corroborate this view. Indeed, girls show higher scores than boys, demonstrating they own a belief's systems about emotions that is consistent with current scientific knowledge on emotional intelligence. In other words, girls believe more than boys that emotions count, and the importance given to emotions could lead girls to never consider themselves good enough in the emotional field.

4.1. Limitations and future directions

We are aware that our study presents some limitation that could be overcome in future studies. Firstly, it could be useful to examine sex differences in a wider range of age groups, and in particular in younger children, in order to see if sex differences are less evident in children than in pre-adolescents. Definitely, longitudinal studies in which emotional and meta-emotional intelligence are measured during transition from childhood to adulthood may give very important insights on their developmental trend. We are also aware that this study is about sex differences and that sex does not always corresponds to gender identity and sexual orientation. For instance, the study focusing on emotional intelligence and sexual orientation realized by Mîndru and Năstasă (2017), evidenced higher levels of both self-reported EI and ability EI in adults with homosexual orientation compared to those with heterosexual orientation. It is not clear to what extent this could be related to results about sex differences and, however, only one study is not enough for making clear conclusions. Moreover, due to the novelty of the paradigm, there is actually no information about meta-emotional intelligence in people with different sexual orientation. Thus, future studies should focus on differences in emotional and meta-emotional intelligence of adolescents and adults that differ not only for biological sex but also for gender identity and sexual orientation. We wonder if gender identity and sexual orientation, more than biological sex, may also predict size and direction of meta-emotional knowledge and meta-emotional self-evaluation.

Abstract: Using a unique data set and a novel identification strategy we explore the effect of the state-level minimum wage increases on firms' existing and new vacancy postings. Utilizing occupation-specific county-level vacancy data from the Conference Board's Help Wanted Online for 2005-2018, we show that the state-level minimum wage increases lead to substantial declines in existing and new vacancy postings for occupations with a larger share of workers earning around the prevailing minimum wage. Our estimate implies that a 10 percent increase in the binding minimum wage reduces vacancies by 2.4 percent contemporaneously, and could be as large as 4.5 percent a year later. The negative effect on vacancies is more pronounced for occupations where workers generally have lower educational attainment (high school or less) and those in counties with higher poverty rates.

3.8 percent of deaths in Mexico are caused by suboptimal temperature (26,000 every year): 92pct of weather-related deaths are induced by cold (below 12 C) or mildly cold (12–20 C) days & only 2 percent by outstandingly hot days (above 32 C)

Abstract: We examine the impact of temperature on mortality in Mexico using daily data over the period 1998–2017 and find that 3.8 percent of deaths in Mexico are caused by suboptimal temperature (26,000 every year). However, 92 percent of weather-related deaths are induced by cold (less than 12 degrees C) or mildly cold (12–20 degrees C) days and only 2 percent by outstandingly hot days (more than 32 degrees C). Furthermore, temperatures are twice as likely to kill people in the bottom half of the income distribution. Finally, we show causal evidence that the Seguro Popular, a universal health care policy, has saved at least 1,600 lives per year from cold weather since 2004.


We hypothesized that restraining the urge to void facilitates honest behavior

Urge to void and dishonest behavior: Evidence from a field experiment. Erez Siniver, Yossef Tobol, Gideon Yaniv. Economics Letters, April 27 2022, 110544. https://doi.org/10.1016/j.econlet.2022.110544

Highlights

• We hypothesized that restraining the urge to void facilitates honest behavior.

• A die-under-the-cup experiment was run in a shopping center with WC entrants and exiters.

• WC entrants cheated significantly less than WC exiters.

• Cheating decreased with the intensity of the urge to void.

Abstract: The present paper reports the results of a study designed to investigate whether restraining the urge to void simultaneously facilitates self-control in the unrelated domain of dishonest behavior. We conducted a field experiment in a big shopping center with passersby who entered or exited the public WC. Participants were recruited by asking WC entrants and exiters if they could spare a few minutes of their time in return for a monetary reward. WC entrants indicated on a short questionnaire the intensity of their urge to void as well as its source (bladder/colon), whereas WC exiters indicated just the latter. All subjects were then offered to perform the Fischbacher and Föllmi-Heusi (2013) die-under-the-cup task which incentivizes cheating. The results reveal that WC entrants cheated significantly less than WC exiters, supporting the hypothesis that inhibiting visceral responses may spill over to inhibiting simultaneous dishonest behavior, and that cheating decreased with the intensity of the urge to void. No significant connection emerged between cheating and the voiding source.

Primitive communism: Adam Smith's & Karl Marx’s idea that societies were naturally egalitarian and communal before farming is widely influential and quite wrong

Primitive communism: Marx’s idea that societies were naturally egalitarian and communal before farming is widely influential and quite wrong. Manvir Singh, AEON, Apr 2022. https://aeon.co/essays/the-idea-of-primitive-communism-is-as-seductive-as-it-is-wrong

[Marx's The Origin of the Family, Private Property and the State]is like Yuval Noah Harari’s blockbuster Sapiens (2014) but written by a 19th-century socialist: a sweeping take on the dawn of property, patriarchy, monogamy and materialism. Like many of its contemporaries, it arranged societies on an evolutionary ladder from savagery to barbarism to civilisation. Although wrong in most ways, The Origin was described by a recent historian as ‘among the more important and politically applicable texts in the Marxist canon’, shaping everything from feminist ideology to the divorce policies of Maoist China.

Of the text’s legacies, the most popular is primitive communism. The idea goes like this. Once upon a time, private property was unknown. Food went to those in need. Everyone was cared for. Then agriculture arose and, with it, ownership over land, labour and wild resources. The organic community splintered under the weight of competition. The story predates Marx and Engels. The patron saint of capitalism, Adam Smith, proposed something similar, as did the 19th-century American anthropologist Lewis Henry Morgan. Even ancient Buddhist texts described a pre-state society free of property. But The Origin is the idea’s most important codification. It argued for primitive communism, circulated it widely, and welded it to Marxist principles.

Today, many writers and academics still treat primitive communism as a historical fact. To take an influential example, the economists Samuel Bowles and Jung-Kyoo Choi have argued for 20 years that property rights coevolved with farming. For them, the question is less whether private property predated farming, but rather why it appeared at that time. In 2017, an article in The Atlantic covering their work asserted plainly: ‘For most of human history, there was no such thing as private property.’ A leading anthropology textbook captures the supposed consensus when it states: ‘The concept of private property is far from universal and tends to occur only in complex societies with social inequality.’

Historical narratives matter. In his bestseller Humankind (2019), Rutger Bregman took the fact that ‘our ancestors had scarcely any notion of private property’ as evidence of fundamental human goodness. In Civilized to Death (2019), Christopher Ryan wrote that pre-agricultural societies were defined by ‘obligatory sharing of minimal property, open access to the necessities of life, and a sense of gratitude toward an environment that provided what was needed.’ As a result, he concluded: ‘The future I imagine (on a good day) looks a lot like the world inhabited by our ancestors…’

Primitive communism is appealing. It endorses an Edenic image of humanity, one in which modernity has corrupted our natural goodness. But this is precisely why we should question it. If a century and a half of research on humanity has taught us anything, it is to be sceptical of the seductive. From race science to the noble savage, the history of anthropology is cluttered with the corpses of convenient stories, of narratives that misrepresent human diversity to advance ideological aims. Is primitive communism any different?

[...]

Is primitive communism another seductive but incorrect anthropological myth? On the one hand, no hunter-gatherer society lacked private property. And although they all shared food, most balanced sharing with special rights. On the other hand, living in a society like the Aché’s was a masterclass in reallocation. It’s hard to imagine farmers engaging in need-based redistribution on that scale.

Whatever we call it, the sharing economy that Hill observed with the Aché does not reflect some lost Edenic goodness. Rather, it sprang from a simpler source: interdependence. Aché families relied on each other for survival. We share with you today so that you can share with us next week, or when we get sick, or when we are pregnant. Hill once saw a man fall from a tree and break his hip. ‘He couldn’t walk for three months, and in those three months, he produced zero food,’ Hill said. ‘And you would think that he would have starved to death and his family would have starved to death. But, of course, nothing happened like that, because everybody provisioned him the whole time.’

This is partly about reciprocity. But it’s also about something deeper. When people are locked in networks of interdependence, they become invested in each other’s welfare. If I rely on three other families to keep me alive and get me food when I cannot, then not only do I want to maintain bonds with them – I also want them to be healthy and strong and capable.

Interdependence might seem enviable. Yet it begets a cruelty often overlooked in talk about primitive communism. When a person goes from a lifeline to a long-term burden, reasons to keep them alive can vanish. In their book Aché Life History (1996), Hill and the anthropologist Ana Magdalena Hurtado listed many Aché people who were killed, abandoned or buried alive: widows, sick people, a blind woman, an infant born too soon, a boy with a paralysed hand, a child who was ‘funny looking’, a girl with bad haemorrhoids. Such opportunism suffuses all social interactions. But it is acute for foragers living at the edge of subsistence, for whom cooperation is essential and wasted efforts can be fatal.

Once that need to survive dissipated, even friends could become disposable

Consider, for example, how the Aché treated orphans. ‘We really hate orphans,’ said an Aché person in 1978. Another Aché person was recorded after seeing jaguar tracks:

Don’t cry now. Are you crying because you want your mother to die? Do you want to be buried with your dead mother? Do you want to be thrown in the grave with your mother and stepped on until your excrement comes out? Your mother is going to die if you keep crying. When you are an orphan nobody will ever take care of you again.

The Aché had among the highest infanticide and child homicide rates ever reported. Of children born in the forest, 14 per cent of boys and 23 per cent of girls were killed before the age of 10, nearly all of them orphans. An infant who lost their mother during the first year of life was always killed.

(Since acculturation, many Aché have regretted killing children and infants. In Aché Life History, Hill and Hurtado reported an interview with a man who strangled a 13-year-old girl nearly 20 years earlier. He ‘asked for our forgiveness’, they wrote, ‘and acknowledged that he never should have carried out the task and simply “wasn’t thinking”.’)

Hunter-gatherers shared because they had to. They put food into their bandmates’ stomachs because their survival depended on it. But once that need dissipated, even friends could become disposable.

The popularity of the idea of primitive communism, especially in the face of contradictory evidence, tells us something important about why narratives succeed. Primitive communism may misrepresent forager societies. But it is simple, and it accords with widespread beliefs about the arc of human history. If we assume that societies went from small to big, or from egalitarian to despotic, then it makes sense that they transitioned from property-less harmony to selfish competition, too. Even if the facts of primitive communism are off, the story feels right.

More important than its simplicity and narrative resonance, however, is primitive communism’s political expediency. For anyone hoping to critique existing institutions, primitive communism conveniently casts modern society as a perversion of a more prosocial human nature. Yet this storytelling is counterproductive. By drawing a contrast between an angelic past and our greedy present, primitive communism blinds us to the true determinants of trust, freedom and equity. If we want to build better societies, the way forward is neither to live as hunter-gatherers nor to bang the drum of a make-believe state of nature. Rather, it is to work with humans as they are, warts and all.

Can people detect the trustworthiness of strangers based on their facial appearance? It seems not.

Can people detect the trustworthiness of strangers based on their facial appearance? Bastian Jaeger et al. Evolution and Human Behavior, May 2 2022. https://doi.org/10.1016/j.evolhumbehav.2022.04.004

Abstract: Although cooperation can lead to mutually beneficial outcomes, cooperative actions only pay off for the individual if others can be trusted to cooperate as well. Identifying trustworthy interaction partners is therefore a central challenge in human social life. How do people navigate this challenge? Prior work suggests that people rely on facial appearance to judge the trustworthiness of strangers. However, the question of whether these judgments are actually accurate remains debated. The present research examines accuracy in trustworthiness detection from faces and three moderators proposed by previous research. We investigate whether people show above-chance accuracy (a) when they make trust decisions and when they provide explicit trustworthiness ratings, (b) when judging male and female counterparts, and (c) when rating cropped images (with non-facial features removed) and uncropped images. Two studies showed that incentivized trust decisions (Study 1, n = 131 university students) and incentivized trustworthiness predictions (Study 2, n = 266 university students) were unrelated to the actual trustworthiness of counterparts. Accuracy was not moderated by stimulus type (cropped vs. uncropped faces) or counterparts' gender. Overall, these findings suggest that people are unable to detect the trustworthiness of strangers based on their facial appearance, when this is the only information available to them.

4. General discussion

People spontaneously rely on the facial appearance of strangers when deciding whether they can be trusted to cooperate in social interactions (Todorov, Olivola, et al., 2015). But can people actually detect the trustworthiness of strangers based on their facial appearance? Prior studies have yielded mixed results and the question remains the subject of vigorous debate (Bonnefon et al., 2017Todorov, Funk, & Olivola, 2015). Yet, the empirical evidence on the topic is limited. Many studies were based on the same set of stimuli, which limits the generalizability of findings (Bonnefon et al., 2013De Neys, Hopfensitz and Bonnefon, 2015De Neys, Hopfensitz and Bonnefon, 2017). Conversely, studies providing evidence against accuracy relied on statistical techniques that cannot quantify evidence in favor of such a null hypothesis, which complicates the interpretation of results (Efferson & Vogt, 2013Rule et al., 2013).

We conducted two studies to address these limitations. Confirming results from previous studies (Jaeger, Evans, Stel, & van Beest, 2019), we found that participants relied on the perceived trustworthiness of counterparts when making trust decisions. However, on average, participants failed to entrust money to counterparts that were actually more trustworthy. Bayesian analyses yielded very strong support for the null hypothesis indicating that our participants were not able to accurately detect the trustworthiness of their interaction partners. We also found that participants' earnings were not higher than the expected earnings of a decision strategy that trusts at random. This suggests that knowledge of their counterparts' facial appearance did not give participants a strategic advantage. In fact, participants would have earned more by consistently distrusting all counterparts, as trust did not pay off in the current sample.

Previous studies found evidence in favor of detection accuracy only under specific conditions, and these conditions varied across studies (Bonnefon et al., 2013Tognetti et al., 2013Verplaetse et al., 2007). Here, we tested these proposed moderators, but found no evidence for better-than-chance trustworthiness detection (a) for male or female counterparts, (b) when making trust decisions or when providing explicit trustworthiness ratings, and (c) when viewing cropped images (in which all non-facial features were removed) or uncropped images. In sum, our results provide consistent evidence against accuracy in trustworthiness detection from faces across various conditions.

Previous investigations have shown that trustworthiness impressions guide decision-making in many domains, including legal sentencing, personnel selection, and financial decision-making (Olivola et al., 2014). People even rely on trustworthiness impressions from faces when more diagnostic cues are available (Jaeger et al., 2019) and when decisions are highly consequential (Wilson & Rule, 2015). Future studies should explore whether some people are more prone to the biasing influence of first impressions and, importantly how biases could be mitigated (for first attempts, see Chua & Freeman, 2021Jaeger, Todorov, Evans, & van Beest, 2020Shen & Ferguson, 2021). An important future task in this line of research will be to delineate how difficult it is to override these biases, particularly when other more reliable information sources are available that may require more cognitive effort to process.

4.1. Limitations and future directions

Several limitations and constraints on the generalizability of the current results should be mentioned. Our results were based on samples of relatively young decision-makers from the University of Zurich. Additional studies are needed to examine the generalizability of our findings with larger and more diverse samples of both targets and raters.

Future studies should also examine the accuracy of trustworthiness impressions using varying types of stimuli. Cropped images, in which all non-facial aspects are removed, ensure that impressions are based on the facial features of counterparts. However, they represent only a relatively specific facet of the kinds of stimuli that people encounter in everyday interpersonal interactions. Accuracy may be better than chance when people have access to additional cues. For instance, previous findings suggest that people may be able to identify cooperative interaction partners with greater-than-chance accuracy after brief interactions (Brosig, 2002DeSteno et al., 2012Frank, Gilovich, & Regan, 1993Reed, Zeglen, & Schmidt, 2012; but see Manson, Gervais, & Kline, 2013McCullough & Reed, 2016). Ultimately, we believe that studies using a wide range of different stimuli are needed to map the accuracy of trustworthiness decisions under varying conditions.

We investigate one such condition here, namely the accuracy of trustworthiness judgments when judgments are solely based on facial features. This approach is informative for two reasons. First, even though people often have access to other cues, which may allow them to make more accurate judgments, there are also many situations in which a person's facial appearance is either one of the only cues or a particularly salient cue. People often engage with strangers and, in the first moments of the interaction, tend to judge them solely based on their appearance. Moreover, facial photographs are a common feature of many decision-making environments, including social media platforms (e.g., Twitter), professional networking sites (e.g., LinkedIn), and the sharing economy (e.g., Airbnb). Second, ample evidence suggests that people rely on facial appearance, even when they have access to other cues (Jaeger et al., 2019Olivola et al., 2014). To determine whether reliance on facial appearance helps or hinders people in making accurate predictions, the accuracy of judgments that are solely based on facial appearance needs to be isolated. This requires a highly controlled and standardized study design, such as the one used in the current experiments, to ensure that judgments are based on the cue in question (Cox et al., 2015).

At Harvard, the admit rates for typical African American applicants are on average over four times larger than if they had been treated as white; for typical Hispanic applicants the increase is 2.4 times

What the Students for Fair Admissions Cases Reveal About Racial Preferences. Peter Arcidiacono, Josh Kinsler & Tyler Ransom. NBER Working Paper 29964. Apr 2022. DOI 10.3386/w29964

Abstract: Using detailed admissions data made public in the SFFA v. Harvard and SFFA v. UNC cases, we examine how racial preferences for under-represented minorities (URMs) affect their admissions to Harvard and UNC-Chapel Hill. At Harvard, the admit rates for typical African American applicants are on average over four times larger than if they had been treated as white. For typical Hispanic applicants the increase is 2.4 times. At UNC, preferences vary substantially by whether the applicant is in-state or out-of-state. For in-state applicants, racial preferences result in an over 70% increase in the African American admit rate. For out-of-state applicants, the increase is more than tenfold. Both universities provide larger racial preferences to URMs from higher socioeconomic backgrounds.



Both genders applied self-deprecating double standards when viewing overweight and average-weight bodies; women, but not men, also showed self-deprecating double standards when viewing the ideal body and their own body

Giving a Body a Different Face—How Men and Women Evaluate Their Own Body vs. That of Others. Mona M. Voges, Hannah L. Quittkat, Benjamin Schöne and Silja Vocks. Front. Psychol., May 2 2022 | https://doi.org/10.3389/fpsyg.2022.853398

Abstract: Eating disorders affect women more than men. Women reportedly dislike their body shape more and appreciate it less than do men. One factor influencing body image might be the application of different standards for oneself than for other people when evaluating bodies. To investigate this possibility, we determined whether the application of double standards is different between men and women. We presented 57 women and 54 men (aged 18–30 and of average weight) with pictures of their own bodies and pictures of average weight, overweight, and “ideal” bodies attached to the participants’ own face and to another person’s face. Participants were instructed to evaluate their emotional reaction to the pictures and then rate the various pictures on aspects of attractiveness, body fat, and muscle mass. The degree of the double standard was defined as the difference between ratings of what appeared to be one’s own body and what appeared to be someone else’s according to the presented face. The analyses revealed, firstly, that both genders applied self-deprecating double standards when viewing overweight and average-weight bodies. Women, but not men, also showed self-deprecating double standards when viewing the ideal body and their own body. By contrast, men applied fewer double standards when viewing the ideal body and self-enhancing double standards when viewing their own body. The study suggests that young, average-weight men are more or less satisfied with their own bodies, whereas young, average-weight women tend to apply a stricter standard for themselves than for others, thus devaluing their own bodies. This vulnerability to body image is hypothesized as contributing to the prevalence of eating disorders in women.


Discussion

The present study was conducted to examine whether women differ from men in the application of double standards in body evaluation. Therefore, we presented the participants’ own bodies and average-weight, overweight, and ideal bodies, once with another face and once with the participant’s face. Women and men were asked to evaluate their emotional reaction regarding valence and arousal and to rate the bodies with regard to body attractiveness, body fat, and muscle mass. Double standard application was measured by the difference between the body ratings generated by the different faces.

First, our hypothesis that women and men would apply self-deprecating double standards in the case of an overweight body was confirmed. For both genders, self-deprecating double standards were observed on all dependent variables. Women and men rated their emotional reaction to an overweight body as more negative and with more arousal. They also rated the overweight body as less attractive, with more body fat, and with less muscle mass when the body had their own face compared to another person’s face. The double standards in valence, arousal, and body fat in the case of the overweight body were more self-deprecating than the double standards in valence, arousal, and body fat for the other body builds. These findings are in line with a previous study that employed cartoon-like body stimuli (Voges et al., 2019b) and might be related to negative stereotypes and stigma associated with overweight and obesity in Western society, e.g., obese people are often stigmatized as “careless,” “disorganized,” and “lazy” (Hu et al., 2018). The activation of self-related schemas through the presentation of one’s own face might result in stricter body evaluations, representing the participants’ rejection of overweight for their own bodies (Voges et al., 2019a).

Contrary to our hypothesis, women also showed self-deprecating double standards for other body builds—average-weight, ideal, and one’s own body—which is not in line with the findings of a previous study using cartoon-like body stimuli, which reported that women applied the same standard to the other images (Voges et al., 2019a). In contrast to the use of cartoon-like bodies in previous studies, participants in the present study evaluated real body stimuli (Voges et al., 2019b). This might have led to a better identification with the body stimuli and might have reinforced body schema activation, resulting in more pronounced double standards in women. Furthermore, as the present study also included women with a BMI of 25–30 kg/m2, the women had a higher average BMI than those in the aforementioned study, and they had higher body dissatisfaction and eating pathology than the sample in the previous study (Voges et al., 2019a). However, most women in the present sample (about 87%) had an average weight according to the WHO criteria, and the average BMI of 21.78 was, as in the previous study, in the lower-average weight category. Furthermore, body dissatisfaction and eating pathology were at an average and not notably different level compared to norms for young women (Paul and Thiel, 2005Mond et al., 2006). Thus, the present results suggest that not only women with eating disorders, but also women without eating disorders, might apply stricter standards for themselves than for others regarding body evaluation, which might foster body dissatisfaction.

The hypothesis that men would show self-enhancing double standards in the case of an ideal body and one’s own body can be partially confirmed by the present findings. With the exception of a self-deprecating double standard in body attractiveness, men showed no double standards for the ideal body, which is not in line with previous findings with artificially created bodies (Voges et al., 2019b). However, in the case of one’s own body, men showed self-enhancing double standards in valence and body attractiveness and no self-deprecating double standards. Although men evaluated the ideal body as more attractive than their own body, identification with this body did not lead to self-enhancing double standards. Thus, young men might have internalized the idea that their own body “fits them well” and does not need to correspond to existing male body ideals in society. This would be in line with findings that men do not believe that the ideal male body is more attainable for themselves than for other men, as women do in the case of the female ideal (Buote et al., 2011). Moreover, this idea would further be consistent with the examined correlations of body appreciation and body dissatisfaction with the self-enhancing double standards in men.

Comparing women’s and men’s body evaluations, women rated in a more self-deprecating manner than did men and, in contrast to men, did not show a self-enhancing double standard for one’s own body. Possibly, female and male stereotypes might contribute to such gender differences in body evaluation (Voges et al., 2019b). According to stereotypes concerning male and female characteristics, men should be “independent,” “strong,” and “outstanding,” while women should be “agreeable” and “friendly” (Guimond et al., 2006). Such stereotypes might simplify self-enhancing evaluation patterns in men while hampering them in women (Meyers-Levy and Loken, 2015). In line with this, men engage more in positive body talk than women (Lin et al., 2021), for whom it seems to be normative to engage in negative fat talk, i.e., degrading the body shape and weight of oneself or others (Tompkins et al., 2009). Thus, women might internalize a devaluation of their own body, while men might be more predisposed to upvalue their own body.

To check whether double standards are associated with body dissatisfaction and body appreciation, we conducted correlation analyses. In line with our hypotheses, the results revealed some associations of body dissatisfaction and body appreciation with double standards in women and men. For women, the higher the body dissatisfaction and the lower the body appreciation, the more self-deprecating was the double standard in valence for one’s own body. Furthermore, the higher the body dissatisfaction, the more self-deprecating were the double standards in arousal and body fat for one’s own body and the double standard in body fat for the overweight body. For men, the higher the body dissatisfaction, the less self-enhancing were the double standards in arousal, body attractiveness, and body fat for one’s own body. Furthermore, as mentioned above, the higher the body appreciation, the more self-enhancing were the double standards in valence and body attractiveness for one’s own body. These findings suggest that double standards related to one’s own body are more directly linked to body dissatisfaction and body appreciation than double standards related to other bodies, as most correlations were found for double standards related to one’s own body and not to the other bodies. This corresponds to the notion that the visual representation of one’s own body is influenced by the attitudes toward one’s own body (Williamson et al., 2004Maister et al., 2020) and that eating pathology is not linked to a generally distorted body perception or cognition but rather to a cognitive–affective distortion in evaluating one’s own body (Behrens et al., 2021). Thus, in addition to stricter standards for oneself, especially in body fat (Voges et al., 2018), eating pathology might be linked to a negative attitude toward one’s own body. With its idiosyncratic characteristics, one’s own body may not match one’s own standard, but may be viewed as more appropriate for other people.

Furthermore, for women, the association with double standards for the overweight body suggests that a stricter disapproval of overweight and obesity for oneself might also foster body dissatisfaction in average-weight women. The fact that no further associations of body dissatisfaction and body appreciation with double standards related to the other bodies (ideal, average-weight, overweight) were observed might also be partially explained by different cognitive reactions to these bodies leading to the same double standard. For example, self-deprecating double standards might emerge in persons with high body dissatisfaction because they generally devalue themselves compared to others and in persons with low body dissatisfaction, because they dislike imagining having the other body, and prefer their own body. Thus, in contrast to the double standards related to one’s own body, the associations between body dissatisfaction or body appreciation and the double standards related to the other bodies might not be so clear.

The present study is the first to examine double standards in body evaluation with photos of bodies including one’s own body and manipulating identification using different faces. By giving a body a different face, we were able to show that identity influences body evaluation differently in women and men. However, some limitations that might restrict the generalizability of the findings should be mentioned. Although the body stimuli were more realistic than those used in a previous study (Voges et al., 2019b), the stimulus material was standardized and gray-scaled, which likely limited the ecological validity. Furthermore, as we used photos of real persons, the bodies naturally differed somewhat in features other than body build (e.g., body height, skin features, body shape). However, for most body build categories, women and men rated the male and female bodies as equally attractive. As we did not assess persons with eating disorders, muscle dysmorphia, or severe body concerns, our results cannot be transferred to these clinical populations. Furthermore, as our study included a photo shoot in which participants wore their underwear, and participants were required to look at photos of their own body, women and men with high body dissatisfaction might have felt too daunted to participate. Based on previous findings with cartoon-like bodies (Voges et al., 2018) and the detected correlations of double standards with body dissatisfaction in this study, it might be assumed that double standards for one’s own body would be more self-deprecating in the case of participants with eating pathology, which should be examined in future studies. Furthermore, samples with a higher BMI, younger or older persons, or persons from different cultures might show different double standards in body evaluation, as body image has been found to differ across the lifespan (Quittkat et al., 2019), across BMI ranges (Calzo et al., 2012), and across cultures (Swami et al., 2010). Thus, the present results provide information about young, highly educated, and average-weight Caucasian women and men, and should be further examined in other samples.

Future studies could use experimental paradigms to clarify which mechanisms result in double standards and whether such double standards in body evaluation play a causal role in body image disturbances. A possible modification of the study design might be to measure eye movements during body evaluation in order to determine whether different identities result in differences in viewing patterns on the same body. Studies indicate that attentional biases may exist depending on identity, especially in individuals with eating disorders (Bauer et al., 2017) or body dysmorphic disorders (Waldorf et al., 2019). Furthermore, following designs for cognitive bias modification training (Dietel et al., 2020), participants could be trained to internalize double standards (e.g., “You have to work harder than others,” “Only the best is good enough for you,” “You have to be slim”), enabling it to be examined whether this manipulation results in more pronounced double standards in body evaluation and in higher body dissatisfaction. In a next step, cognitive bias modification training (Dietel et al., 2020) or evaluative conditioning paradigms (Glashouwer et al., 2018) could also be used to potentially reduce self-deprecating double standards. Furthermore, preventive strategies that emphasize the diversity and positive aspects of bodies, especially for women (Cohen et al., 2021), or seek to prevent widespread dysfunctional behaviors, such as fat talk (Mills and Fuller-Tyszkiewicz, 2017), or promote positive body talk (Alleva et al., 2021) might be promising. In particular, the newer body neutrality movement on social media which encourages women to attach less importance toward physical appearance might be a helpful approach (Cohen et al., 2021), as findings indicate that the evaluation of neutral characteristics is less biased by the identity of the person being assessed than the evaluation of very desirable or undesirable characteristics (John and Robins, 1993).

In sum, the present study extends previous findings of gender differences in applying double standards to self and other body evaluation. Women, relative to men, are self-depreciating. When their own face is attached to differently shaped bodies, they apply stricter standards of attractiveness, which may account for the prevalence of body image disturbances in women.

Following an incident of misconduct, female financial advisers are 20% more likely to lose their jobs and 30% less likely to find new jobs; gap is not driven by gender differences in occupation, productivity, nature of misconduct, or recidivism

When Harry Fired Sally: The Double Standard in Punishing Misconduct. Mark Egan, Gregor Matvos, and Amit Seru. Journal of Political Economy, Apr 2022. https://doi.org/10.1086/718964

Abstract: We examine gender differences in misconduct punishment in the financial advisory industry. There is a “gender punishment gap”: following an incident of misconduct, female advisers are 20% more likely to lose their jobs and 30% less likely to find new jobs, relative to male advisers. The gender punishment gap is not driven by gender differences in occupation, productivity, nature of misconduct, or recidivism. The gap in hiring and firing dissipates at firms with a greater percentage of female managers and executives. We also explore the differential treatment of ethnic minority men and find similar patterns of “in-group” tolerance.


Combining data from exams taken at Swedish military enlistment with earnings records from the tax register, we document an increase in the relative labor market return to logical reasoning skill as compared to vocabulary knowledge

Labor Market Returns and the Evolution of Cognitive Skills: Theory and Evidence Get access Arrow. Santiago Hermo, Miika Päällysaho, David Seim, Jesse M Shapiro. The Quarterly Journal of Economics, qjac022, Apr 19 2022. https://doi.org/10.1093/qje/qjac022

Abstract: A large literature in cognitive science studies the puzzling “Flynn effect” of rising fluid intelligence (reasoning skill) in rich countries. We develop an economic model in which a cohort’s mix of skills is determined by different skills’ relative returns in the labor market and by the technology for producing skills. We estimate the model using administrative data from Sweden. Combining data from exams taken at military enlistment with earnings records from the tax register, we document an increase in the relative labor market return to logical reasoning skill as compared to vocabulary knowledge. The estimated model implies that changes in labor market returns explain 37 percent of the measured increase in reasoning skill, and can also explain the decline in knowledge. An original survey of parents, an analysis of trends in school curricula, and an analysis of occupational characteristics show evidence of increasing emphasis on reasoning as compared to knowledge.

Individual factors, particularly low status, and social forces, such as a high degree of status inequality, female empowerment, and the ease of coordination through social media, give rise to misogynistic extremism

Lindner, Miriam. 2022. “Alone Together and Angry: Misogynistic Extremism as Coalitional Bargaining for Sexual Access.” PsyArXiv. April 30. doi:10.31234/osf.io/pve8u

Abstract: Mass shooters, violent extremists, and terrorists, who are overwhelmingly male, exhibit misogynistic attitudes and a history of violence against women. Over the past few years, incels (“involuntary celibates”) have gathered in online communities to discuss their frustration with sexual/romantic rejection, espouse male supremacist attitudes, and justify violence against women and men who are more popular with women. Despite the link between misogyny and mass violence, and the recent emergence of online misogynistic extremism, theories and empirical research on misogynistic extremism remain scarce. I apply theorizing on the function of coalitional aggression as one of bargaining over collective conflicts of interest to the domain of sexual aggression and explore how sexual rejection can be framed as a grievance and make violence attractive. I show how individual factors, particularly low status, and social forces, such as a high degree of status inequality, female empowerment, and the ease of coordination through social media, give rise to misogynistic extremism.



The Gendered Consequences of Risk-Taking at Work: No evidence for overall gender differences in initial risk-taking

The Gendered Consequences of Risk-Taking at Work: Are Women Averse to Risk or to Poor Consequences? Thekla Morgenroth, Michelle K. Ryan, Cordelia Fine. Psychology of Women Quarterly, April 18, 2022. https://doi.org/10.1177/03616843221084048

Abstract: Women are seen as more risk-avoidant in the workplace, and some have argued that this contributes to occupational gender gaps. Across two correlational and three experimental studies (total N = 2280), we examined the role of consequences of workplace risk-taking in determining the likelihood of taking future risks at work. We found no evidence for overall gender differences in initial risk-taking, and women and men anticipated similar consequences for risks with which they have no experience. However, this stands in contrast to the consequences of risk-taking they have experienced. Here, men reported on average more positive consequences, even for those risks that are more normative for women, translating into a higher likelihood of taking the same risks again. When faced with the same consequences, women and men were equally likely to take the same risks again. Our findings challenge the simple assumption that women are averse to workplace risks and suggest that if and when women do avoid risks, it is because their risk-taking leads to less rewarding consequences. Workplace gender equality initiatives should therefore tackle any inequities of consequences rather than encouraging women to “lean in” and take more risks.

Warfare among foragers who lived among foragers and were not subject to control by a state: Conflict occurred on all scales ranging from small-scale raids to battles involving hundreds of warriors on each side; large-scale conflict caused many casualties and much mortality; larger scale conflict was more common between members of different ethnolinguistic or tribal groups than within such groups

Large-scale cooperation in small-scale foraging societies. Robert Boyd, Peter J. Richerson. Evolutionary Anthropology: Issues, News, and Reviews. April 29 2022. https://doi.org/10.1002/evan.21944

Abstract: We present evidence that people in small-scale mobile hunter-gatherer societies cooperated in large numbers to produce collective goods. Foragers engaged in large-scale communal hunts and constructed shared capital facilities; they made shared investments in improving the local environment; and they participated in warfare, formed enduring alliances, and established trading networks. Large-scale collective action often played a crucial role in subsistence. The provision of public goods involved the cooperation of many individuals, so each person made only a small contribution. This evidence suggests that large-scale cooperation occurred in the Pleistocene societies that encompass most of human evolutionary history, and therefore it is unlikely that large-scale cooperation in Holocene food producing societies results from an evolved psychology shaped only in small-group interactions. Instead, large-scale human cooperation needs to be explained as an adaptation, likely rooted in distinctive features of human biology, grammatical language, increased cognitive ability, and cumulative cultural adaptation.

 5.2.4 Iñupiaq in northwestern Alaska

During the first half of the 19th 560 century, Iñupiaq groups in western Alaska conducted regular
 large-scale warfare against members of other Iñupiaq groups, Athabaskan speakers to the east, and
Chukchi people on the Asian side of the Bering Strait. Our knowledge of these events comes from
Iñupiaq ethnohistory collected by the anthropologist Ernest “Tiger” Burch100 563 who interviewed Iñupiaq elders about 19th 564 century Iñupiaq life, conflict and alliance. By collecting and collating many accounts of the same events, he was able to create a picture of Iñupiaq life before extensive contact with Europeans and North Americans.
The Iñupiaq economy was based on fishing and hunting large game, mainly caribou and marine
 mammals. They lived in villages during the fall and winter, and then moved to fishing and hunting camps in the spring and summer. Population densities were about 1 person per 20 square kilometers, at the low end of the forager range. Villages ranged in size from 8 to 160 people, but 80% had less than 32 people.
People were collected into territorial groups that Burch refers to as nations. In the region
around Kotzebue Sound there were 10 nations with an average population size of 470 people and
average territory size of 8600 km2.

Burch100:140 recorded accounts of 77 raids and battles that occurred in the first half of the 19th 574
century. Like other foraging groups, attackers preferred surprise, nighttime raids. These occurred mainly in the fall because low temperatures meant that people would be inside at night, frozen rivers made travel easier, and the lack of snow made it difficult to track retreating raiders. Raiding parties armed with bows, lances and knives travelled long distances, sometimes as much as 300km each way, and never less than 80km.
 
 Villages were centered around a community hall or qargi where men spent much of their evenings. Attackers hoped to surprise all the men in the qargi and kill them as they exited.
 If the raid was successful, attackers killed everybody in the village. Sometimes young women were taken as slaves, but usually they were raped, tortured and killed100:104 582
 The threat of raids prompted people to take defensive action. Some villages had defensive
 stockades, and others were surrounded by fields of sharpened caribou bones driven into the ground,
 much like the punji sticks used by Viet Cong fighters. They also built escape tunnels into the qargi.
Raiders were sometimes detected and ambushed themselves.

 Small villages could be attacked by  raiding parties numbering 10 or 20 warriors. However, Iñupiaq sometimes attacked larger villages, and this required much larger raiding parties. It was more difficult to feed a large war party during travel, and larger villages were harder to approach undetected, but nonetheless, raids on large villages did occur.

Burch gives detailed accounts of several large raids. For example, raiding party of 350−400 men attacked a village of about 600 people. The attackers wore camouflaged clothing and came bare593 footed to minimize the chance their approach would be heard. However, they were spotted, and the
 Point Hope villagers poured out and attacked the raiders who retreated onto a field studded with
 caribou spikes rendering many of them helpless. Their comrades fled leaving the injured to be killed by the defenders.

Sometimes the Iñupiaq engaged in large open battles. This could occur when a large raiding party was detected, but sometimes they took place when the animosity between two nations had reached a boiling point.

In open battles, the two sides formed battle lines with the best archers on the flanks. Then the two sides would exchange archery fire, sometimes for hours. If one side was getting the worst of it, they might sometimes flee, experiencing serious casualties. Sometimes the two  sides would close and engage in hand to hand combat armed with lances and knives.
