Abstract
Objective: To understand migration from an evolutionary perspective, this phenomenon has so far been mainly investigated in animal species. We therefore aim to investigate the potential evolutionary roots of attitudes toward migrants in humans.

Methods: We used data from the European Social Survey (n = 83 734), analyzing attitudes toward migrants by performing ordinal mixed models.

Results: We found that men have a more restrictive attitude toward migration than women, which increases with age and is stronger with a child in the household. Attitude toward migrants is also more skeptical if migrants have a different ethnicity and are from poorer countries. Increasing education and religiousness are associated with a more positive attitude toward migrants, particularly toward migrants of different ethnicity and from poorer countries.

Discussion: Although migration flows are a hallmark of the human species, previous findings suggest that (pre‐)historic migration flows were at times accompanied by conflict and violence, while at the same time, they insured survival by allowing cultural exchange and the avoidance of inbreeding. Accordingly, we assume that contemporary attitudes toward migration are rooted in our evolutionary past. We discuss the respective behavioral patterns from an evolutionary perspective, arguing that both—a negative attitude as well as openness—make sense.

4 DISCUSSION

Overall (integrating all countries and rounds of the ESS), we find that the majority of respondents prefer moderate migration (ie, “allow some to come”), particularly if migrants have the same ethnic background. A very open attitude toward migration (“allow many to come”) is only favored by a minority, and this open attitude is declining the more “out‐group” the migrants are (from 24.56% for migrants of the same ethnicity to 14.94% and 13.99% for migrants of different ethnicity and poorer countries, respectively). We further find that men are generally more skeptical toward migration than women. Odds ratios further indicate that this difference between men and women is higher if migrants have different ethnic background or come from poorer countries.

We would argue that these differences in attitudes between men and women may also be rooted in our evolutionary past. The genome—as a chronicler of past sexual encounters—reveals much about past (and particularly prehistoric) human interactions. In Europe, for instance, the main genetic component before the arrival of the Yamnaya consisted of the Anatolian farmers and small populations of ancient hunter gatherers. The arrival of the Yamnaya people in Europe about 5000 years age (Fu et al., 2016; Goldberg et al., 2017; Reich, 2018) dramatically changed the genetic landscape of Europe, particularly the paternal lines of heredity: the proportion of Y‐chromosomes inherited from the residential Anatolian farmers (who entered Europe approximately 8000 years ago) and the remaining ancient hunter gatherer populations (being in Europe since 40.000 years) declined rapidly after the arrival of the male‐biased Yamnaya migration (Goldberg et al., 2017) and even became extinct in some regions (Olalde et al., 2019). Both in Europe and also the Indian subcontinent, the Y‐chromosomal data indicate that the newly arriving migrants mixed with the resident female population, to the massive disadvantage of the local male population, leading to a virtual extinction of the residential male population (described in Reich, 2018). The Yamnaya themselves emerged out of an admixture of two populations some 7000 to 5000 years ago formed through a steady genetic influx from two populations from the south into the Steppe (Ukraine/Russia) (Haak et al., 2015). They grew in size and eventually headed west and also south‐east as far as India. But not only the Yamnaya expansion is an impressive example for a displacement of ancient residential male populations but also the Anglo Saxon invasion in Britain (Weale, Weiss, Jager, Bradman, & Thomas, 2002) and most recently the male dominated colonization of the Americas (Reich et al., 2012).

On the other hand, there are also numerous examples of—presumably—less violent prehistoric migrations, which eventually led to the admixture of different populations in the long run; such as the migration of Anatolian farmers, that led to an almost replacement of the resident hunter‐gatherer population and a very slow admixture among both groups. This rather slow migration of agriculturalist families over a longer period of time from Anatolia to Europe ~8000 years ago (Fu et al., 2016; Goldberg et al., 2017; Nielsen, Akey, Jakobsson, et al., 2017; Skoglund et al., 2012) first resulted in “parallel societies” of resident hunter‐gatherers and agriculturalist but later led to an admixture of both populations. In this case, no evidence of the sex‐specific admixture has been found. However, in both cases, after the Anatolian expansion as well as after the Yamnaya spread, data indicate a resurgence of the genetic representation of the residential inhabitants: during the Middle Neolithic, hunter‐gatherer ancestry rose again after its Early Neolithic decline, and then between the Late Neolithic and the present, when farmer and hunter‐gatherer ancestry rose after its Late Neolithic decline (Haak et al., 2015). Archeological evidence indicates that the rather slow migration wave from Anatolia seems to have been less violent compared to the Yamnaya expansion, but recent data also suggest that violence also has been occurred during the Anatolian expansion (Alt et al., 2020).

From the perspective of evolutionary psychology, however, the examples of violent encounters (Jantzen et al., 2011; Wild et al., 2004) might at least partially explain why men are more skeptical toward migration. In addition, the Y‐chromosomal asymmetric mixing contributes evidence to the long debated question if male aggression and violence would be adaptive or not, in particular, inter‐group aggression and killing (Archer, 2009, Daly, 2015, Macfarlan, Walker, Flinn, & Chagnon, 2014, Glowacki & Wrangham, 2015, reviewed in Wrangham, 2018). Clearly, the invading Yamnaya mended have reproductive and thus evolutionary benefits.

Our data also show that women are not per se more migration friendly compared tome but that in women more than in men, attitude toward migration changes with age. As women grow older, they become increasingly more skeptic of migration, whereas younger women are on average more migration friendly. This “friendliness” in younger women might be interpreted in the light of female dispersal (Huber, Zahourek, & Fieder, 2017). In the Paleolithic, hunter‐gatherer mating networks (Sikora et al., 2017) may have existed, which may have helped to avoid inbreeding by “marriage migration” between groups. Particularly, young women may have left their natal group to live with their husband's family (Seielstad, Minch, & Cavalli‐Sforza, 1998; Sterck, 1998; Towner, 2002), a scenario, where friendliness toward strangers would probably be advantageous. In addition, in the case of hostile group encounters, women have faced a substantially lower danger of being injured or killed (Wrangham, 2018) which was particularly true if they had a more out‐group friendly attitude. Furthermore, openness toward strangers may have fostered cultural exchange between groups that in terms of acquired and transmitted practices and techniques may have been advantageous for survival in hostile environments (Henrich, 2015). The finding that women may become more skeptical toward migration with increasing age, may also be interpreted on the basis of theory on general intelligence with a ability to learn new information and seek novel experiences at younger ages and a later life combination of these information and experiences to a “crystallized knowledge” (Geary, 2004). These findings indicate that selection may be acting at least to some extent antagonistically in men and in women (Connallon, Cox, & Calsbeek, 2010).

Overall, increasing age is associated with a more skeptical attitude toward migrants in both men and women. Although odds ratios indicate that the increase per year of life is rather small, over the whole life span, this effect accumulates to result in a substantial shift from a more positive to a more skeptic attitude. This finding is in line with the literature on changes of attitudes during the course of life (Visser & Krosnick, 1998).

The finding that having at least one child in the household (a rough proxy of ever reproducing) is associated with a more skeptical attitude toward migration of people of different ethnicity and from poorer countries indicates that individuals who have reproduced have a more critical attitude toward some kinds of migration compared to never reproducing individuals. We can only speculate why this is the case. Maybe parents are worrying for the future of their progeny, if the social tensions that are at times associated with migration are taken into account.

Our data further show that two parameters may have the potential to lower skepticisms toward migration: education and religiousness. Higher education is not only associated with a positive attitude toward migration, in particular toward migration of different ethnic background. Indicated by the odds ratios, the size of the effect of education, increasing from the lowest to the highest education level and leading to a higher acceptance of migrants particularly from a different culture, is comparable to that of sex. This migration‐friendly attitude may be interpreted as an effect of education per se, as education particularly in western societies is usually strong emphasizing mutual understanding and tolerance (Craft, 2017). However, individuals with higher education are usually better off in terms of resources compared to less educated people. As a result, higher educated individuals are usually less directly affected by migration, for instance, in terms of competition on the job or housing market (Collier, 2013).

Also religiousness is associated with a more positive attitude toward migration. Odds ratios indicate that over the full scale, religiousness has a comparable effect size as sex and education. This more positive attitude may be interpreted by the charitable characteristics of religion and the highly inclusive potential of some religions (Huber & Fieder, 2018; Norenzayan, 2013). This view is supported by the finding that the positive attitude is even higher if migrants have different ethnic background or come from poorer countries. Hence, this finding could be an indication for the integrative power of some religions even though religions also have a clearly excluding character, leading to intergroup conflicts (Seul, 1999). Nonetheless, the tendency to integrate individuals from different ethnic background maybe interpreted by the integrative power of religions during the agricultural revolution—when people with a different ethnic and cultural background settled into larger agglomerations (Norenzayan et al., 2016)—as well as inherent moral dogmas. However, our sample is by far mostly from predominantly “Christian countries.” In the models we calculated separately for the only predominantly Muslim country in our sample “Turkey” (only Muslims, parents born in Turkey and no experience of discrimination reported), we found no significant association between religious intensity and attitude to migrants whatsoever (data not shown).

As expected, a more right wing political attitude is associated with a more restrictive attitude toward migrants, particularly if migrants have a different ethnicity or are from poorer countries. As political attitude is encoded on an 11‐item scale, over the total range of the scale, despite rather small odds ratios, the association of the political attitude with the attitude toward migration is substantial. An association between right wing orientation and skepticism toward migration has also been demonstrated by Hatemi and McDermott (2012). Also, twin studies have shown that political attitude has a genetic basis (Hatemi & McDermott 2012) and in‐group favoritism has in part a genetic basis that may contribute to this trait. The variance in “in‐group favoritism” explained by inheritance in twin studies is varying greatly from 18% to 79% depending on the actual trait surveyed and how the in‐group has been defined (Kandler, Lewis, Feldhaus, & Riemann, 2015; Lewis, Kandler, & Riemann, 2014; Loehlin, 1993). Constructing a sum indicator of all three questions on the attitudes toward migrants and regressing political attitude on this indicator, attitude toward migrants explains about 16% of the variance in political attitude of the survey participants. Hence, as expected, the attitude toward strangers and political orientation is associated and explains a certain proportion of variance. Overall, we assume that political orientation is a trait that evolved in an interplay between genes and the environment (Alford et al., 2011; Hatemi & McDermott, 2012), that is, as a process of a cultural genetic coevolution (Richerson, Boyd, & Henrich, 2010). As political orientation has a rather strong genetic basis, both left wing and right wing political orientation should have brought benefits to the bearer from an evolutionary point of view. Accordingly, political orientation (both left and right) is related to the number of offspring, indicating reproductive advantages for the political extreme (Fieder & Huber, 2018). However, this pattern shifted in Western industrial countries to only a reproductive advantage for the political right (Fieder & Huber, 2018). In line with Stearns, Byars, Govindaraju, and Ewbank (2010), it can be assumed that this reproductive differential maybe suitable to indicate selective forces for political orientation.

The overall more reluctant attitude to migrants of a different ethnicity compared with the attitude toward migrants of the same ethnicity may indicate some sort of ethnic nepotism toward more similar individuals (Rushton, 1989, Salter & Harpeding, 2013), thus humans may have preferred individuals where they detected genetic similarity and that such a behavior may have overall enhanced fitness (Rushton et al., 1985, Rushton, 1989, Salter & Harpeding, 2013). On basis of data from 183 countries worldwide, Vanhanen found evidence that ethnic division tends to lead to conflicts of interest between ethnic groups and that the more a society is ethnically divided, the more political and other conflicts arise along ethnic line (Vanhanen, 1999), as well as intensities along religious borders (Salter, 2018). Also, ethnic nepotism maybe adaptive if it helps to secure resources and territory (Salter, 2002). Furthermore, religious and ethnic homogamy increases the average number of children and decreases childlessness (Fieder & Huber, 2016b; Huber & Fieder, 2018). It has been demonstrated on the basis of data from Iceland, that average offspring number decreases with genetic relatedness from second‐order cousins on (Helgason, Pálsson, Guðbjartsson, & Stefánsson, 2008) and thus during our evolutionary past moderate inbreeding may have led to reproductive benefits (Fox, 2015).

Ethnic nepotism may have some serious drawbacks, as individuals may become overall—or for certain traits—more homozygote with all the known consequences (Clark et al., 2019, Fieder, Huber, & Martin, n.d., submitted). Particularly in small‐scale societies of mostly not more than 150 individuals (Dunbar, 1993), the burden of inbreeding may have been large in the case of ethnic nepotism. Ethnic nepotism and the rejection of strangers, as well as a more open attitude toward strangers, always depend on the actions of others. Therefore, such an adopted strategy may lead to an evolutionary stable strategy under certain conditions (Smith, 1976) with different characteristics within a group. Ethnic nepotism has no concept of “ethnic kinship” (such as kinship between parents and children) that would make this more distant “altruism” reasonable. A way out of this dilemma has been proposed by Jones (2018), indicating that ethnic is nepotism expressed by a group toward their own kin and thus individuals of similar phenotypes. In‐group marriages in small groups fostered genetic relatedness also among individuals that are more distantly related than close kin and thus in‐group cooperation among individuals that are genetically more related as indicated by simple kinship. An argument quite closely related to Hamilton (Hamilton, 1964, 1971) and West et al. (2011). Accordingly, William D. Hamilton also argued that successfully expanding groups are expected to evolve to some extent a degree of xenophobia (Hamilton, 1996). But ethnic nepotism may have resulted in high levels of inbreeding with all the related consequences and thus a process of balancing selection may have been beneficial: some individuals with a propensity for an increased out‐group cooperation.

Thus we assume that balancing selection may help to explain the attitudes toward strangers: both a more open attitude as well as a more guarded attitude may have led to benefits for the bearer, and so both attitudes have been kept in the population (Charlesworth, 2006; Fieder & Huber, 2018)—presumably at different frequencies, depending on the environment and circumstances. Evidence for a balancing selection on the “attitudes to strangers” maybe found in the polymorphisms of alleles that are associated with this attitude. If balancing selection would have been acting on alleles associated with attitudes toward strangers, balancing selection may have increased the polymorphism of loci that are associated with the trait “attitude toward strangers”. We are not aware of any GWA study that already identified loci associated with the attitude toward in‐group vs out‐group members; hence, this argument remains speculative at the moment. One hint for balancing selection is evidence from the World Value Survey: as in the case of political attitude, individuals with a more critical attitude toward strangers have on average more children (data not published). Balancing selection may explain different attitudes toward strangers, while differences between men and women may be additionally explained by a “sex‐specific selection”. The same trait may lead to different reproductive outcomes for men and women and thus for different selection pressures on the sexes (Connallon et al., 2010).

Our data set provides no information on the attitude toward strangers and pathogen prevalence, but pathogens may have also been important in shaping our attitude toward strangers. Infectious diseases clearly increased morbidity and mortality throughout human history; this may particularly hold true since the rise of agricultural societies and thus more dense human populations (Wolfe, Dunavan, & Diamond, 2007). Previous research demonstrated worldwide variability in pathogen prevalence, predicting some cultural differences ranging from food habits (Sherman & Billing, 1999), marriage structures (Low, 1990), parenting practices (Quinlan, 2007), and mate choice (Gangestad & Buss, 1993). Interestingly, it seems that attitudes of collectivism (eg, ethnocentrism, conformity) can inhibit the transmission of pathogens. Fincher, Thornhill, Murray, and Schaller (2008) demonstrated on the basis of worldwide data that the regional prevalence of pathogens correlates strongly positive with cultural indicators of collectivism but strongly negative with individualism. However, admixture and thus heterozygosity may help to cope better with diseases and infections, as heterozygosity seems to improve also the health condition of individuals and thus may increase protection against pathogens (Clark et al., 2019). This may especially hold true for major histocompatibility complex heterozygosity (Penn, Damjanovich, & Potts, 2002; Xu et al., 2019).

From an evolutionary point of view, a more negative attitude toward migrants and a positive attitude toward migrants make sense: In some cases, migration may include violence with detrimental outcomes for certain groups (particularly men). On the other hand, isolation may lead to lack of cultural exchange and to an increase in inbreeding.1Considering the size of populations in contemporary Europe, inbreeding avoidance has to be considered an evolutionary inherited trait as it has limited relevance today. Also, the necessity of cultural exchange to thrive (Henrich, 2015) has been altered by contemporary technology allowing global communication and information exchange.

Our findings are also in line with Eibl‐Eibesfeldt, who suggested that with regard to strangers, humans are “an ambivalent species,” displaying both timidity and interest—particularly in the case of recurring interactions (Eibl‐Eibesfeldt, 1986). Thus, in our evolutionary history, both traits may have been crucial for survival and we assume that both—evolutionary acquired—predispositions are still present in contemporary populations and influence the perception of migration flows. Migration‐friendly vs migration‐skeptical attitude may serve as an example of a genetic cultural coevolution (Henrich, 2015; Richerson et al., 2010). As our data are based on European populations, our conclusions are, of course, limited to this group.

To conclude, we would like to stress that it is of utmost importance to note that evolutionary acquired mind‐sets are not a predicament. Human behavior has in many ways improved during the history of our species, taming detrimental instincts and making us “better angels or our nature” as Steven Pinker put it (Pinker, 2011).

On the Limited Generality of Air Pollution and Anxiety as Causal Determinants of Unethical Behavior: Lu, Lee, Gino, and Galinsky's theory is incompatible with other evidence and thus overly broad

On the Limited Generality of Air Pollution and Anxiety as Causal Determinants of Unethical Behavior: Commentary on Lu, Lee, Gino, and Galinsky (2018). Daniel W. Heck, Isabel Thielmann, Sina A. Klein, Benjamin E. Hilbig. Psychological Science, May 26, 2020. https://doi.org/10.1177/0956797619866627

Abstract: Lu, Lee, Gino, and Galinsky (2018) recently proposed a “causal effect of psychologically experiencing a polluted (vs. clean) environment on unethical behavior” (p. 340) and mediation of this effect by increased anxiety. Supporting their first hypothesis, Lu and colleagues reported a positive effect of air pollution on annual crime rates in 9,360 U.S. cities. Moreover, correlation analyses supported the proposed mediation by anxiety when dishonesty was measured after participants saw photographs of clean or polluted environments. Here, we argue that Lu and colleagues’ theory is incompatible with other evidence on unethical behavior and thus overly broad.

First, the hypothesis that air pollution directly causes crime conflicts with ample evidence that crime rates are higher in summer than in winter (McDowall, Loftin, & Pate, 2012), plausibly because of higher temperatures increasing frustration and aggression and changes in individuals’ activity patterns (Hipp, Curran, Bollen, & Bauer, 2004). In turn, air pollution is markedly higher in winter than in summer (Massey, Kulshrestha, Masih, & Taneja, 2012), which is mainly because of emissions from increased use of heating and vehicles. That seasonal trends of crime rates and air pollution are exactly opposed is difficult to reconcile with Lu and colleagues’ hypothesis of a causal pollution–crime link.

A more restrictive version of Lu and colleagues’ theory might be that pollution has incremental predictive validity for crime over and above seasonal trends. Indeed, Bondy, Roth, and Sager (2020) showed that the Air Quality Index (AQI) has incremental validity beyond temperature and other control variables on crime. However, the effect was confined to less severe offenses (e.g., pickpocketing), and null effects occurred for more severe offenses (e.g., murder). Moreover, the AQI includes ground-level ozone, which is negatively correlated with the pollutants used in Lu and colleagues’ operationalization of pollution. Likewise, Herrnstadt, Heyes, Muehlegger, and Saberian (2018) showed incremental effects of ozone and particulate matter on crime rates when controlling for temperature. However, these effects were limited to specific pollutants and violent crimes (e.g., assault). The authors therefore concluded that “this seems to be a story about violence - not criminality in general” (p. 23). Overall, it thus remains unresolved whether pollution generally affects unethical behavior beyond seasonal trends. In Study 1, we addressed this question using monthly data on air pollution and crime rates.

Second, Lu and colleagues provide only limited evidence that anxiety causes unethical behavior. In their Studies 2 and 3, participants imagined living in a clean versus polluted city depicted on photographs. However, “experiencing” air pollution in this way might simply increase negative mood; thus, other emotional states (e.g., anger, negative affect, frustration) than anxiety may have increased unethical behavior. Indeed, “investigations of ‘an emotion’ are most probably investigations of several simultaneous emotions” (Polivy, 1981, p. 816). Thus, measuring both anxiety and dishonesty as dependent variables of the experimental manipulation and testing mediation can provide only weak evidence for the supposed mediator because of possible confounding variables (Fiedler, Schott, & Meiser, 2011). Other studies in which the causal effect of anxiety on unethical behavior was investigated by manipulating mood (e.g., H. Zhang, Shi, Zhou, Ma, & Tang, 2018) suffer from similar limitations.

Sidestepping the requirement for mood manipulations, we tested whether a stronger inclination toward experiencing anxiety is associated with increased unethical behavior. Specifically, in Study 2, we investigated whether trait anxiety as assessed by HEXACO Emotionality and its Anxiety facet (Ashton & Lee, 2007) is positively related to dishonesty. Originally, Lu and colleagues’ theory was concerned with state anxiety, defined as distress or physiological arousal in reaction to the potential for undesirable outcomes (Brooks & Schweitzer, 2011). However, state anxiety is (by definition) what individuals high in trait anxiety should more likely experience across various situations. Thus, unless Lu and colleagues are referring to some form of state anxiety that is independent of trait anxiety, their reasoning implies a positive correlation between trait anxiety and dishonesty.

Indeed, Kouchaki and Desai (2015) showed that both state and trait anxiety are positively linked to unethical behavior at work. Nevertheless, they explicitly limited the generality of their conclusions, because “anxiety sometimes may act as a motivator of ethical [italics added] behavior” (p. 371). Likewise, mortality salience (linked to the potential of experiencing anxiety) reduced dishonest behavior when honesty was made salient (Schindler et al., 2019), and social anxiety correlated only with some types of unethical behavior (Wowra, 2007). Other studies provided further evidence against a relation of trait anxiety (operationalized by emotionality, neuroticism, or emotional stability) to hypothetical and actual criminal behavior (e.g., Aseltine, Gore, & Gordon, 2000; Rentfrow, Gosling, & Potter, 2008; van Gelder & de Vries, 2012). In Study 2, we tested whether trait anxiety is also unrelated to incentivized dishonest behavior using a large-scale reanalysis.

...

Conclusion

Our analyses and reanalyses provided consistent evidence against the generality of a causal effect of air pollution on unethical behavior via anxiety. First, pollution showed no incremental effect on crime rates above opposing seasonal trends. Second, trait anxiety was unrelated to dishonest behavior. These findings clearly conflict with Lu and colleagues’ broad hypotheses, demonstrating that neither air pollution nor anxiety can be considered general causes of unethical behavior.

As a remedy, Lu and colleagues may specify more precisely which types of “air pollution” (e.g., experienced vs. objective, types of pollutants) and anxiety (e.g., specific versions of state anxiety, negative emotions) lead to different aspects of unethical behavior (e.g., dishonesty, violence). For instance, Lu and colleagues’ theory could be restricted to (a) specific pollutants, (b) a 6-month lag between peaks in pollution and crime, (c) a subset of crimes (even though we consistently found null effects), (d) specific emotional states elicited by their experimental manipulation, or (e) specific types of state anxiety that are independent of trait anxiety.

Indeed, such restrictions and the fact that they require further theoretical justifications (e.g., why should there be a 6-month delay?) may not appear attractive. However, theory revision is the straightforward option that fosters scientific progress. Thus, we encourage Lu and colleagues to revise their claims in terms of generality and scope and thereby exclude those portions of the “empirical content” (in terms of falsifiability; Popper, 2002) of their theory that our and other evidence conflicts with.

We judge our own true selves, our authentic and fundamental nature, to be better than that of others

My True Self is Better Than Yours: Comparative Bias in True Self Judgments. Yiyue Zhang, Mark Alicke. Personality and Social Psychology Bulletin, May 26, 2020. https://doi.org/10.1177/0146167220919213

Abstract: Researchers have assumed that people judge their own true selves, or their authentic and fundamental nature, to be no better than that of others. This assumption conflicts with self-enhancement perspectives, and with studies on comparative biases in self and social judgment, which assume that people tend to view their characteristics and life prospects more favorably than those of others. The five studies in this article demonstrate that comparative bias operates in self versus other true self comparisons, both with regard to traits (Studies 1–3), and morally relevant behaviors (Studies 4 and 5). Implications for the true and authentic self constructs are discussed.

Research relying on measures of feelings toward the opposing “Party” vastly overstates levels of partisan animosity in the American public; we need to distinguish between attitudes toward party elites & ordinary partisans

Who Do You Loathe? Feelings toward Politicians vs. Ordinary People in the Opposing Party
Jon Kingzette. Journal of Experimental Political Science, May 26 2020. https://doi.org/10.1017/XPS.2020.9Published

Abstract: Scholars, the media, and ordinary people alike express alarm at the apparent loathing between Democrats and Republicans in the mass public. However, the evidence of such loathing typically comes from survey items that measure attitudes toward the Democratic and Republican Parties, rather than attitudes toward ordinary partisans. Using a nationally representative survey, I find that Democrats and Republicans have substantially more positive feelings toward ordinary people belonging to the opposing party than they do toward politicians in the opposing party and the opposing party itself. These results indicate that research relying on measures of feelings toward the opposing “Party” vastly overstates levels of partisan animosity in the American public and demonstrate the need to distinguish between attitudes toward party elites and ordinary partisans in future research.

The difference between dealmakers & dealbreakers was larger among women (error management theory) & sex differences in responses were dependent on individual differences in psychopathy, sociosexuality, & disgust

Should I stay or should I go: Individual differences in response to romantic dealmakers and dealbreakers. Peter K. Jonason, Kaitlyn P. White, Laith Al-Shawaf. Personality and Individual Differences, Volume 164, 1 October 2020, 110120. https://doi.org/10.1016/j.paid.2020.110120

Highlights
• Researched change in romantic interest when learning dealmakers and dealbreakers
• Greater sex difference in dealbreakers than dealmakers
• Dealbreakers caused more change than dealmakers in women, equivalent change in men.
• Sociosexuality and psychopathy associated with less change to dealbreakers
• Mating success and extraversion associated with more change to dealmakers

Abstract: People glean key information about their potential mates during the early phases of courtship. Here (N = 261) we investigated how much learning “dealmaker” (i.e., positive) and “dealbreaker” (i.e., negative) information changed men and women's interest in potential romantic partners. We derived hypotheses from prospect theory and error management theory about loss aversion and how personality traits may enable people's sexual agendas. We found that dealbreakers and dealmakers both influenced participants' level of interest, but this effect was larger for dealbreakers (i.e., prospect theory). We found that the difference between dealmakers and dealbreakers was larger among women (i.e., error management theory) and that sex differences in responses to dealbreakers and dealmakers were fully mediated by individual differences in psychopathy, sociosexuality, and disgust. Our discussion focuses on the utility of an evolutionary framework in studying the early stages of relationship formation.

Vegetarians were 3 to 6 times more likely to have vegetarian friends than omnivores were, & 12 times more likely to have romantic partners who were vegetarians than omnivores were

Nezlek, John B., Marzena Cypryanska, and catherine forestell. 2020. “Dietary Similarity of Friends and Lovers: Vegetarianism, Omnivorism, and Personal Relationships.” OSF Preprints. May 25. doi:10.31219/osf.io/vs3z5

Abstract: In a series of studies conducted in the USA and Poland, we found that vegetarianism can serve as a basis for the formation of personal relationships. Consistent with research on the similarity-attraction effect, we found that vegetarians were more likely than omnivores to have friends and lovers who were vegetarians. In study 1, vegetarians reported that their diets were a more important part of their identities than omnivores did. In studies 2, 3, and 4, we found that vegetarians were three to six times more likely to have vegetarian friends than omnivores were. In study 4 we found that vegetarians were twelve times more likely to have romantic partners who were vegetarians than omnivores were. These results suggest that following a vegetarian or an omnivorous diet is an important influence on an individual’s choice of relational partners, possibly because dietary choice is part of an individual’s social identity.

Role of individual differences for development and manifestation of wisdom, approaches to wisdom development and training, & cultural, subcultural, and social-contextual differences

Grossmann, Igor, Nic M. Weststrate, Monika Ardelt, Justin P. Brienza, Mengxi Dong, Michel Ferrari, Marc A. Fournier, et al. 2020. “The Science of Wisdom in a Polarized World: Knowns and Unknowns.” PsyArXiv. May 26. doi:10.1080/1047840X.2020.1750917

Abstract: Interest in wisdom in the cognitive sciences, psychology, and education has been paralleled by conceptual confusions about its nature and assessment. To clarify these issues and promote consensus in the field, wisdom researchers met in Toronto in July of 2019, resolving disputes through discussion. Guided by a survey of scientists who study wisdom-related constructs, we established a common wisdom model, observing that empirical approaches to wisdom converge on the morally-grounded application of metacognition to reasoning and problem-solving. After outlining the function of relevant metacognitive and moral processes, we critically evaluate existing empirical approaches to measurement and offer recommendations for best practices. In the subsequent sections, we use the common wisdom model to selectively review evidence about the role of individual differences for development and manifestation of wisdom, approaches to wisdom development and training, as well as cultural, subcultural, and social-contextual differences. We conclude by discussing wisdom’s conceptual overlap with a host of other constructs and outline unresolved conceptual and methodological challenges.

Character strengths as wisdom in disguise?

The last several decades have not only seen the emergence of the psychometric base to the wisdom construct, but also a proliferation of potentially related constructs. Psychological scientists so far have not considered the conceptual and psychometric relationship of such constructs to wisdom. Below we provide two examples. This list is not exhaustive and questions below may be applied broadly.

Intellectual humility. Several constructs have recently emerged under the umbrella rubric of character strengths and virtues (e.g., Bleidorn & Denissen, 2015; Fleeson, Furr, Jayawickreme, Meindl, & Helzer, 2014; Peterson & Seligman, 2004) , which include a range of characteristics such as courage, gratitude (e.g., DeSteno, Li, Dickens, & Lerner, 2014; McCullough, Kilpatrick, Emmons, & Larson, 2001) , compassion (Goetz, Keltner, & Simon-Thomas, 2010) and forgiveness (McCullough, 2000) . Some of these constructs have their roots in the virtue theory and Christian theology, and have become popular within the positive psychology movement (Seligman & Csikszentmihalyi, 2014) . One character strength that has received a great deal of attention concerns (intellectual) humility (e.g., Leary et al., 2017; Stellar et al., 2018; Van Tongeren, Davis, Hook, & Witvliet, 2019) , defined as the “ability to accurately acknowledge one’s limitations and abilities and (b) an interpersonal stance that is other-oriented rather than self-focused” (Van Tongeren et al., 2019) . Intellectual humility was the focus of Socrates' definition of wisdom and the overlap of this conceptual definition with the common wisdom model is striking, raising the question about the distinctiveness of humility from wisdom, and the discriminant validity of the extant measures. Indeed, several of the most common measures aiming to capture the common wisdom model (Table 1) include intellectual humility as a central facet. Moreover, features of humility and wisdom are listed among the 28 measurable character strengths (Peterson & Seligman, 2004) . Undoubtedly, intellectual humility is an important concept in a time of ever increasing political polarization (Haidt & Lukianoff, 2018; Leary et al., 2017) . The question that remains open concerns its uniqueness beyond the PMC components it shares with the common wisdom model advanced in the present target article. If it is just a facet of the same broader construct, researchers studying humility and wisdom may benefit from insights from respective fields, including concerns with measurement levels and usability of the self-report scales (see Section 3). After all, most humility instruments so far appear to involve abstract self-ratings, even though the process they arguably aim to capture concern is meta-cognitive and thereby is not easily amendable to abstract self-beliefs (Brienza et al., 2018; Grossmann, Dorfman, et al., 2020) . Abstract self-beliefs may be self-deceiving or used for purposes of impression management (Dunning, Heath, & Suls, 2004; Kihlstrom, Eich, Sandbrand, & Tobias, 2000; T. D. Wilson & Bar-Anan, 2008) , raising questions whether a person claiming that they are “much more humble than you would understand” accurately expresses their humility.

Open-mindedness. A related characteristic that has experienced a resurgence in scientific interest concerns open-mindedness. The construct itself is not new and can be traced to theories by Carl Rogers and others (e.g., Rogers, 1954) . Indeed, the initial intent of the openness factor of the OCEAN model of personality has included open-mindedness (for review, John, Naumann, & Soto, 2008 , esp. Table 4.2). However, whereas openness/open-mindedness in personality research has been conceptually defined as a description of “the breadth, depth, originality, and complexity of an individual’s mental and experiential life” (John et al., 2008) , there appears to be no unified definition of open-mindedness neither as a character strength nor as a thinking disposition. Some scholars define and proceed to measure it as intellectual flexibility and openness to diverse viewpoints in the process of making a decision (Fujita, Gollwitzer, & Oettingen, 2007; Price, Ottati, Wilson, & Kim, 2015) . Others define it almost identically to the definition of humility above, as “an intellectual quality displayed by someone who recognizes that her belief could be wrong, so her mind is subject to change” (Spiegel, 2012) . And yet others define open-minded thinking as “the disposition to weigh new evidence against a favored belief heavily (or lightly), the disposition to spend a great deal of time (or very little) on a problem before giving up, or the disposition to weigh heavily the opinions of others in forming one's own” (Baron, 1985 , p. 15; also see Stanovich & West, 1997). The conceptual confusion concerning open-mindedness is particularly evident in the puzzling observations that open-minded thinking appears to be positively related to political polarization about climate change (Kahan & Corbin, 2016) : If the definition of open-mindedness involves openness to diverse viewpoints and a potential of one being wrong, one ought to expect less polarization among more open-minded individuals! Similar to the concept of humility, this conceptual confusion raises questions about the meaning of the term, as well as the overlap with the definition of wisdom as a morally-grounded PMC. Researchers on open-mindedness may benefit from the present discussion of the common wisdom model, which may provide a roadmap for conceptual and methodological clarification of the open-mindedness construct, as well.

Overall, bodies of research on character strength and thinking dispositions have not sufficiently clarified the relationship to psychological characteristics of wisdom. Is wisdom one of many virtues linked to creativity, open-mindedness, perspective, and innovation, and distinct from humility, prudence, or justice (Peterson & Seligman, 2004) ? Both the common wisdom model advanced here and the relevant psychometric evidence are inconsistent with this perspective: The common wisdom model involves psychological characteristics of humility, prudence, as well as moral aspirations concerning justice and fairness. An alternative possibility advanced in Aristotelian and Thomistic virtue ethics is that wisdom (or prudence) represents a cardinal meta-virtue allowing one to discern which actions to pursue in concrete circumstances one may be experiencing (e.g., Darnell et al., 2019; Schwartz & Sharpe, 2006) . In relationship to thinking dispositions or character strengths, wisdom may be represented as a tool allowing one to figure out which of the character traits are more relevant in a given situation. This perspective is consistent with the common wisdom framework advanced here, with PMC oriented towards discerning the fit between one’s dispositions, one’s goals, and the features of a given situation. However, this “cardinal virtue” perspective requires measurement of the fit between one’s tendencies and the situational demands across multiple diagnostic situations, to estimate whether PMC indeed allows one to flexibly switch between different behaviors to optimally fit the context of a new situation. No psychometric instruments for the assessment of character strengths (e.g., Fleeson, Furr, Jayawickreme, Meindl, & Helzer, 2014) , thinking dispositions (e.g., Baron, 2019; Perkins, Jay, & Tishman, 1993; Stanovich & West, 2002) or wisdom (Staudinger & Glück, 2011) have so far even attempted to assess relevant characteristics within such “strategy-situation fit” framework.

Toward a psychological and cognitive science of wisdom

Beyond individual differences in character strengths and thinking dispositions, the common wisdom model as morally-grounded PMC also has implications for research on consciousness and artificial intelligence. We review possible connections and a range of unanswered questions below.

Consciousness. Within the body of research on consciousness, some researchers have suggested three different levels of awareness (e.g., Pinard, 1992; Schooler, 2002), including unconscious processes, basic conscious processes, and meta-conscious processes. At the implicit or enacted level of consciousness, experience is embedded in the actions one is experiencing. At the explicit level of consciousness, the person engages in conscious processing of the phenomena. At the third, meta-conscious level, the person deliberately and consciously takes charge of their cognitive functioning (Damasio, 1999; Pinard, 1992; Proust, 2013; Winkielman & Schooler, 2011) -- i.e., one becomes aware of the content of one’s conscious processes in ways that become increasingly transparent. The concept of meta-consciousness shares a great deal in common with the meta-cognitive components central to the empirical conceptualizations of wisdom (see Figure 1). Both require a perspectival appreciation of one’s conscious experience (e.g., experience of the inadequacy of one’s explanations of a given concept). Moreover, theoretical and empirical work on meta-consciousness suggests that the processes triggering meta-consciousness (Winkielman & Schooler, 2011) may be relevant for boosting wisdom as well. At the same time, the lack of moral grounding for the concept of meta-consciousness, compared to its centrality to the common wisdom model, raises the questions about the limits of the conceptual overlap. Is meta-consciousness a necessary, but not sufficient aspect of wisdom? If meta-consciousness is necessary for wisdom, can wisdom ever become habitual or automatic? Are the individuals prone to mind-wandering more or less likely to think wisely? Answers to these questions can help better understand the concept of wisdom from a cognitive science perspective, including the role of implicit, automatic, and physiological processes.

Artificial intelligence. Artificial intelligence (AI) research typically aims to develop “rational,” intelligent agents, a quality attributed to devices that adaptively react to the environment and take actions that maximize their chances of successfully achieving their goals (Russell & Norvig, 2016) . Notably, AI is often attributed to those qualities that machine devices have not yet mastered – an observation often described as the Tesler’s Theorem (Hofstadter, 1980 , p. 601) or the AI effect (McCorduck, 2004) . Given the steady AI advances in the domains of speech comprehension, language translations, and human-superior performance on strategic games such as chess or Go, a question arises: Will AI at some point be able to acquire wisdom? The development of “wise” AI systems is of special relevance in the time of ethical debates concerning the use of AI and machine-learning approaches to human-machine interactions, autonomous cars, political advertising, and criminal court decisions. For some time, AI researchers have recognized the hierarchy of Data, Information, Knowledge, and Wisdom (DIKW), in which data represent measurements or symbols, information is the application of data to answer questions, knowledge depends on the context of question and answer, and wisdom depends on values. Indeed, there is a growing recognition that values need to be incorporated into the development of AI (Conn, 2017) . On the surface, advances in AI-based knowledge representation, expert systems, and planning suggest that some aspects of human wisdom may be approximated via the AI. At the same time, the ideal of a goal-oriented, rational agent central to the AI research (Russell & Norvig, 2016) can be idiosyncratic to the common characteristics of a wise person: Under many circumstances, a wise person may choose a socially conscious, reasonable option, rather than preference-maximizing rational option (Rawls, 1971; Toulmin, 2001) . This characterization of a wise person is not idiosyncratic, as it is shared among laypeople across a range of contemporary societies (Grossmann, Eibach, et al., 2020) . Whether AI researchers can go beyond the maxim of goal-oriented optimization and to simulate psychological characteristics of wisdom in the context of ill-defined problems remains an open question. How will AI be able to integrate the influx of multi-model streams of information with moral aspirations as suggested by Asimov’s zeroth law or robotics (1986) ? Without doubt, “wise” AI requires discerning where, when, and to what degree to apply different rules for processing information, but it also requires optimization towards resolution of certain trade-offs (e.g., trade-offs between general and context-specific strategies). Perhaps a first step in testing the viability of a “wise” AI will be contingent on the development of systems capable to effectively simulate PMC common to psychological wisdom in the context of complex, social issues.

Women overestimated the thinness that men prefer in a partner and men overestimated the heaviness and muscularity that women prefer in a partner

Misperceptions of opposite‐sex preferences for thinness and muscularity. Xue Lei  David Perrett. British Journal of Psychology, May 25 2020. https://doi.org/10.1111/bjop.12451

Abstract: Thin and muscular have been characterized as ideals for women and men, respectively. Little research has investigated whether men and women have accurate perceptions of opposite‐sex preferences of thinness and muscularity. Further, no study has explored whether opposite‐sex perceptions of thinness and muscularity preferences differ for short‐term and long‐term relationships. The present study set out to address these questions. We used interactive 3D human models to represent bodies varying in size (body mass index/BMI weight scaled by height) and body composition. University‐aged (18–31) White European heterosexual men and women were asked to choose their own and ideal body shape, the ideal body shape for a short‐ and a long‐term partner, and the body shape they thought the opposite‐sex would most like for short‐ and long‐term partners. Women overestimated the thinness that men prefer in a partner and men overestimated the heaviness and muscularity that women prefer in a partner. These misperceptions were more exaggerated for short‐term relationships than for long‐term relationships. The results illustrate the importance of investigating misperceptions of opposite‐sex preferences and raise the possibility that correcting misperceptions might have utility in reducing body dissatisfaction or eating disorders.

Caveats

It is worth noting that although the BMI and Fat% of the own ideal and preferred partner bodies are within the healthy range, the values may not truly represent realistic human figures. The body models used in the current study were generated through a mobile app. The extent to which the models accurately reflect the body weight and muscularity of real human bodies remains unclear. Compared with previous findings (Stephen & Perera, 2014; Tovée, Reinhardt, Emery, & Cornelissen, 1998), the ideal female body figure found in the current study is heavier in terms of BMI. For example, the associated BMI of the attractive female bodies or faces found in previous studies was as low as 17 (Stephen & Perera, 2014), and the highest was around 20 (Tovée et al. , 1998). The BMI of women’s ideal body figure in the present study is around 21 and this figure is even higher for men’s preference, which is around 22. Clearly, the ideal female body size is higher in the current study than in previous studies. By the same token, the ideal male body size might also be higher compared to previous work. The discrepancy of the most attractive BMI between the current and previous studies might be due to the different stimuli used. The 3D human body models used in the current study might appear thinner than 2D human body’s photographs used in previous studies given the same BMI. In fact, one previous study has found that BMI of the most desirable 3D male faces is higher than that of the 2D male faces (Lei et al. , 2018). Future study comparing the accuracy of perception of weight from 2D and 3D images might provide more understanding.

Previously, studies examining preferences of body size mainly used line drawings or photographs of different individuals; few used controlled interactive photographs or model images. Even though some studies used real individual body images, body composition was not taken into consideration. Future studies exploring the body weight and shape that are attractive in men and women should use realistic photographs of human bodies and control for other body parameters that influence physical attractiveness like waist to hip ratio. Nonetheless, even though the absolute values of BMI and Fat% of the preferred male and female bodies may not truly represent the most attractive figures of men and women in real life, the aim of the present study was to compare preferences between the two sexes. Thus, the accuracy of the representations of human body models should not affect the misperceptions of opposite‐sex preferences found here.

In addition, the current study used body fat percentage rather than muscle mass as the measurement of muscularity (Holzleitner & Perrett, 2016; Sturman, Stephen, Mond, Stevenson, & Brooks, 2017). We note that a low body fat percentage does not necessarily equate to a high muscularity, particularly when BMI is low (e.g. <20). Nevertheless, the results suggest that men’s underestimation of the body fat percentage women desire accompanies the overestimation of heaviness (BMI ~ 27) that men believe women prefer. Hence, it is appropriate to conclude that men overestimate muscularity that women prefer. We hope that future studies will be able to use of muscle mass to measure preferences for male muscularity.

Conclusion

In conclusion, using models of human bodies with various levels of BMI and Fat%, the current study revealed that misperceptions of opposite‐sex preferences exist in young men and women. In particular, women tend to overestimate the thinness of female bodies that men prefer, and men tend to overestimate the muscularity of male bodies that women prefer. Moreover, these misperceptions are more exaggerated for short‐term relationships. Women mistakenly believe that men would like thinner women for short‐term than for long‐term relationships, while men misperceive that women would like more muscular men for short‐term than for long‐term relationships. Future research on body image should evaluate the influence that misperceptions of opposite‐sex preference have on body dissatisfaction and other body image related psychological problems.

Logically incompatible conspiracy beliefs may show a high correlation in subjects

Imhoff, Roland, and Pia Lamberty. 2020. “A Bioweapon or a Hoax? The Link Between Distinct Conspiracy Beliefs About the Coronavirus Disease (COVID-19) Outbreak and Pandemic Behavior.” PsyArXiv. April 14. doi:10.31234/osf.io/ye3ma

Abstract: Exploring the association of distinct conspiracy beliefs (COVID-19 is a hoax; SARS-Cov-2 was human-made) with pandemic-related behavior.

General Discussion

We observed similarly problematic correlates of two distinct conspiracy beliefs concerning the coronavirus pandemic. Depending on whether COVID-19 was believed to be a hoax or the SARS-Cov-2 human-made participants indicated less compliance with selfreported infection-reducing containment-related behavior and more engagement in selfreported self-centered prepping behavior targeting not a reduction of the infection rate but personal benefits in the crisis. Although these associations seem relatively straight-forward, it is important to note that previous research has pointed to the danger of conspiracy beliefs but has dedicated less attention to potentially distinct relations of different kinds of conspiracy beliefs. These distinct associations notwithstanding, our results also provide strong support for the general notion that even logically incompatible conspiracy beliefs show a high correlation and are both positively associated with a general mindset of conspiracy mentality.

Adding to the robustness of the findings, another study conducted within the German context (reported in the Supplement) closely replicated this general pattern. This seems noteworthy as another dataset from the German context failed to find strong relations between conspiracy endorsement and hygiene measures (Pummerer & Sassenberg, 2020).


Limitations and further research

As arguably the most important limitation of our research, all findings are crosssectional correlations and thus mute with regard to causality. Although it seems plausible that people adapt their behavior according to how they see and perceive the world, it is also conceivable that people behave in a certain way (for no or other reasons) and adapt their worldview as a justification after the fact. Another clear limitation is that these studies were conducted in a time of rapidly changing world events and thus might not have undergone the amount of planning and detailed pre-registration as generally desirable for any kind of research question (Scheel, 2020). Applying a stricter alpha level (e.g., p = .005; for a discussion see Benjamin et al., 2018) would yield the negative impact of hoax belief on selfreported containment-related behavior in the UK non-significant after including all control variables. Trusting in the readers’ intuition to interpret the results we refrain here from forcing a binary significant- non-significant decision on these data but merely point to the substantially weaker data pattern in the UK compared to the US.

Conditionability of 'voluntary' and 'reflexive-like' behaviors, with special reference to elimination behavior: It seems promising to promote studies on latrine training in cattle

Conditionability of 'voluntary' and 'reflexive-like' behaviors, with special reference to elimination behavior in cattle. Neele Dirksen. Neuroscience & Biobehavioral Reviews. May 24 2020. https://doi.org/10.1016/j.neubiorev.2020.05.006

Highlights
• Indiscriminate excretion by cattle is a source of environmental pollution.
• No successful toilet training in cattle yet.
• Various brain centres, the ANS and the SNS are involved in the control of elimination.
• Toilet training of cattle should be possible using operant conditioning techniques.

Abstract: Typically, cattle urinate and defecate with little or no control over time and place. The resulting excreta contributes to a range of adverse effects on the environment and the animals themselves. These adverse effects could be substantially ameliorated if livestock could be toilet trained. Toilet training requires an animal to suppress impending voiding (a reflexive-like behavior), move to a latrine (voluntary behavior) and reinitiate voiding. Here, we review the neurophysiological processes and learning mechanisms regulating toileting. The suppression and initiation of voiding occur primarily via the coordinated activity of smooth and striated anal and urinary sphincter muscles. The autonomic and somatic nervous systems, along with central processes, regulate these muscles. In several mammalian species, voluntary control of the sphincters has been demonstrated using classical and/or operant conditioning. In this review, we demonstrate that the neurophysiological and behavioral regulation of voiding in cattle is likely to be similarly conditionable. The management of excreta deposition in cattle could have major benefits for reducing livestock greenhouse gas emissions and improving animal health/welfare.

6. Summarizing conclusion and practical outlook

We have described the neurophysiology of voiding reflexes and have shown that there are both voluntary and involuntary responses involved in initiation and control of voiding. Regarding the conditionability of voiding, we have described how operant methodologies are mainly applicable to modifying voluntary behavior and classical methodologies are mainly applicable to changing involuntary behavior although there is potential for these to crossover. Further, we have argued that because many voluntary behaviors need to be trained in successful toileting and because involuntary behavior is also susceptible to operant conditioning, operant conditioning is likely to be the main tool for training latrine use in cattle.

For successful latrine training, animals must learn to recognize the impending need to void (Element a), withhold urination/defecation until reaching the latrine, void (Element b) and then leave the toilet.

It is well known that cattle must learn many tasks in farming systems, and these are often self-taught (or by social learning) or trained with little input from the animal carers. For example, cattle learn autonomously the location of essential resources in the living environment, and how to operate equipment such as automatic feeders, water dispensers and entry to automatic milking systems (Wechsler and Lea, 2007). Furthermore, various studies have shown that it is possible to use operant conditioning to teach cows to move reliably to a certain place after prompting with visual (Kiley-Worthington and Savage, 1978), acoustic (Kiley-Worthington and Savage, 1978; Wredle et al., 2004, 2006) or vibrational signal (Seo et al., 2002) that serve as discriminative stimuli.

Therefore, cattle have a ready propensity to learn to move to specific locations, which is an important element in training latrine use. Cattle appear to be able to learn to associate urination with a specific location (Vaughan et al., 2014a), and another study found that cattle appear to have an awareness of an association between their elimination behavior and rewards (Whistance et al., 2009). These observations mean that the second part of latrine training (voiding in a specific location) should also be achievable. In practical situations, it would be important for an animal to leave the latrine area after voiding. Leaving the toileting area is an operant response, and, therefore, it should be readily trainable, as for movement into the latrine. Although reflexes are often classically conditioned, the results with other species suggest that latrine training with operant conditioning would seem to be more promising. As continence is controlled not only by the detrusor muscle and internal (smooth muscle) urethral sphincter of the urinary bladder (both under involuntary control) but also by the external urogenital sphincter (striated muscles), which is under voluntary control (Arya and Weissbart, 2017), it is likely that operant rather than classical conditioning procedures will be more useful for latrine training. Therefore, it seems promising to promote studies on latrine training in cattle, particularly using operant conditioning methodology.

This review is mainly concerned with the feasibility of latrine training of cattle from a neurophysiological and learning theory point of view. The next obvious steps are to test the ability of cattle to learn the full latrine training process and the potential for practical implementation. To ensure ready applicability of latrine training on farms, ideally, the training should be undertaken with minimal input from the animal caretakers. One possibility would be to link remotely-detected signs of voiding initiation (e.g., changes in tail position), movement toward a latrine and voiding in a latrine with remotely activated reward presentation. A number of technologies could be utilized for such purposes including thermal imaging, machine vision and machine learning which have been used, for example, in the automated detection of parturient and other behaviors in a range of species including cattle (Miller et al. 2020; Wurtz et al., 2019) and for the automated training of rodents (e.g., Poddar et al., 2013).

If feces and urine were voided into latrines, the alleys and cubicles in the barn would much less soiled, which means that the hooves and udder would have reduced exposure to high levels of bacteria on the floor surfaces, thereby contributing to improved animal health (Santman-Berends et al., 2016; Sarjokari et al., 2013). In addition, alleys would no longer need to be cleaned as much, providing labor and cost savings (Brantas, 1968; Chapinal et al., 2013; Somers et al., 2005). Furthermore, the environmental aspect of this approach should not be forgotten. The use of latrines would help to mitigate the emission of greenhouse gases such as N2O and NH3 by making it possible to collect and separate feces and urine (van Dixhoorn et al., 2017).

We have provided solid evidence that toilet training is within the learning capacities of cattle. Our motivation for writing the review is to provide a resource to inspire researchers to explore innovative methods to reduce some of the deleterious effects of cattle farming on climate change and animal health and welfare.

Rolf Degen summarizing... Love is half blind: Long term romantic relationships are cemented by willful ignorance of the the better half's unflattering sides

Murray, Samuel, Ph.D., and Peter Finocchiaro. 2020. “These Confabulations Are Guaranteed to Save Your Marriage! Toward a Teleological Theory of Confabulation.” PsyArXiv. May 25. doi:10.31234/osf.io/huywk

Abstract: Confabulation is typically understood to be dysfunctional. But this understanding neglects the phenomenon's potential benefits. In fact, we think that the benefits of non-clinical confabulation provide a better foundation for a general account of confabulation. In this paper, we start from these benefits to develop a social teleological account of confabulation. Central to our account is the idea that confabulation manifests a kind of willful ignorance. By understanding confabulation in this way, we can provide principled explanations for the difference between clinical and non-clinical cases of confabulation and the extent to which confabulation is rational.

Sanctification and Cheating Among Emerging Adults

Sanctification and Cheating Among Emerging Adults. Paige McAllister, Elena Henderson, Meghan Maddock, Krista Dowdle, Frank D. Fincham & Scott R. Braithwaite. Archives of Sexual Behavior volume 49, pages1177–1188, Mar 16 2020. https://link.springer.com/article/10.1007/s10508-020-01657-3

Abstract: Cheating—a general term for extradyadic romantic or sexual behavior that violates expectations in a committed romantic relationship—is common and leads to a number of poor outcomes. Religion has historically influenced conceptions of romantic relationships, but societal attitudes about religion are in flux as many seek to retain spirituality even as affiliations with formal religion decrease. The present study evaluated a potential predictor of cheating that is more spiritual than formally religious, the “psychospiritual” concept of relationship sanctification (i.e., the idea that one’s relationship itself is sacred). In a sample of college students in committed relationships (N = 716), we found that higher levels of self-reported relationship sanctification were associated with a lower likelihood of both physical and emotional cheating even when accounting for plausible alternate explanations (general religiosity, problematic alcohol use, and trait self-control). This association was mediated via permissive sexual attitudes; specifically, higher levels of sanctification were associated with less permissive sexual attitudes which, in turn, predicted a lower likelihood of emotional and physical cheating.

Long‐term potentiation serves as one of the mechanisms affording learning and memory storage in neuronal circuits

The history of long‐term potentiation as a memory mechanism: Controversies, confirmation, and some lessons to remember. Hans C. Dringenberg. Hippocampus, May 22 2020. https://doi.org/10.1002/hipo.23213

ABSTRACT: The discovery of long‐term potentiation (LTP) provided the first, direct evidence for long‐lasting synaptic plasticity in the living brain. Consequently, LTP was proposed to serve as a mechanism for information storage among neurons, thus providing the basis for the behavioral and psychological phenomena of learning and long‐term memory formation. However, for several decades, the LTP‐memory hypothesis remained highly controversial, with inconsistent and contradictory evidence providing a barrier to its general acceptance. This review summarizes the history of these early debates, challenges, and experimental strategies (successful and unsuccessful) to establish a link between LTP and memory. Together, the empirical evidence, gathered over a period of about four decades, strongly suggests that LTP serves as one of the mechanisms affording learning and memory storage in neuronal circuits. Notably, this body of work also offers some important lessons that apply to the broader fields of behavioral and cognitive neuroscience. As such, the history of LTP as a learning mechanism provides valuable insights to neuroscientists exploring the relations between brain and psychological states.

Investment in stocks led to a more right‐leaning outlook merit & deservingness, personal responsibility, & equality, & a shift to the right on policy questions, driven by decreasing distrust of markets

How Markets Shape Values and Political Preferences: A Field Experiment. Yotam Margalit  Moses Shayo. American Journal of Political Science, May 22 2020. https://doi.org/10.1111/ajps.12517

Abstract: How does engagement with markets affect socioeconomic values and political preferences? A long line of thinkers has debated the nature and direction of such effects, but claims are difficult to assess empirically because market engagement is endogenous. We designed a large field experiment to evaluate the impact of financial markets, which have grown dramatically in recent decades. Participants from a national sample in England received substantial sums they could invest over a 6‐week period. We assigned them into several treatments designed to distinguish between different theoretical channels of influence. Results show that investment in stocks led to a more right‐leaning outlook on issues such as merit and deservingness, personal responsibility, and equality. Subjects also shifted to the right on policy questions. These results appear to be driven by growing familiarity with, and decreasing distrust of markets. The spread of financial markets thus has important and underappreciated political ramifications.

Discussion

Financial markets have an increasing presence in countries throughout the world. From the stock market tickers on the TV screens at the local store, through the ups and downs in people's pension savings, to the torrent of tweets of the current U.S. president about the Dow Jones' performance, more and more people are exposed to financial markets. However, little is known about the political ramifications of this trend. This article presents the first experimental analysis of how mass exposure to financial markets affects social values and preferences over economic policies. We find that engagement with financial markets brings about a rightward shift in values and attitudes. This effect is quite general and, if anything, appears to be stronger among voters on the left. Furthermore, the effect is most pronounced when individuals invest in actual stocks rather than in nonfinancial assets, a pattern consistent with an Exposure Channel. The most likely mechanism underlying these shifts is growing familiarity with and decreasing distrust of markets. This is reflected in growing confidence in people's ability to successfully invest in the market.

These results suggest a rather inconspicuous effect of the growing financial sector on politics, an effect that goes beyond the visible and widely discussed channels of influence, such as large campaign contributions, lobbying activity, or the prominence of Goldman Sachs executives in the U.S. government. By encouraging a pro‐market social and political outlook, markets may engender a self‐sustaining dynamic whereby their growing reach leads to wider support for their further expansion.

Our findings suggest a link between growing trust in financial markets and more right‐leaning socioeconomic values. A pertinent question is whether the opposite effects also hold true. Put differently, would growing distrust in financial (or other) markets lead to a leftward shift? Exploiting instances when markets were tainted by scandals (e.g., Barclays' Libor manipulation, Enron, Madoff), future research may be able to isolate the effect of trust in markets on socioeconomic preferences.

This is a first attempt at evaluating experimentally the impact of exposure to investing in the stock market on social values. The volatility of the market during the experimental treatment was higher than average because of the Brexit. While of course both treatment and control groups experienced the same external conditions, it is an open question whether lower market volatility would have produced weaker or stronger effects. Assuming that greater market uncertainty tends to decrease trust in markets, it seems reasonable to conjecture that the results we report underestimate the magnitude of the general effect. Future replications of this type of study will help shed light on this conjecture.

The interpretation and policy implications of our results depend, to some extent, on one's ideological dispositions. Some might find it troubling, for example, that engagement in financial markets decreases participants' appreciation of the need for a social safety net and for regulation of markets. Others, however, may applaud the effect of market participation on the way people think about personal responsibility for individual choices and achievements. Some may also celebrate the reduced support for market regulation. Similarly, people may disagree in how they interpret the finding that exposure to investment activity generates confidence (or, perhaps, overconfidence) in financial markets as a savings vehicle for the masses, including for people's pensions.

This latter point speaks to a growing policy trend of governments encouraging citizens to invest in the stock market via subsidies and tax breaks. The United States, for example, seeks to encourage savings by allowing tax‐deferred retirement funds for those making investments in Roth IRAs. In 2017, the Israeli government replaced some of the traditional child‐rearing assistance funds with a savings plan for every child. Rather than receiving cash, parents receive funds that they can invest in various savings vehicles, such as mutual funds. To date, these policies were assessed and debated with respect to their economic effects. Our findings suggest that such policies may also have meaningful political repercussions.

Suicide terrorists may have been subject to over-theorization: Countries with higher share of deaths from suicide displayed higher incidences of suicide attacks but similar incidences of non- suicide ones

Varaine, Simon. 2020. “The Statistical Logic of Suicide Terrorism.” PsyArXiv. May 22. doi:10.31234/osf.io/sgfje

Abstract: The self-sacrifice of suicide terrorists is subject to sophisticated models of altruistic sacrifice. Yet, a simpler account is that it reflects common suicidal tendencies. This paper offers new micro and macro evidence supportive of this hypothesis. Study 1 compared a sample of suicide and non-suicide terrorists in the United States from 1948 to 2017. Results indicated that suicide terrorists were more likely to display various established suicidal risk factors including history of child abuse, absent parent/s and relationship troubles. Study 2 took advantage of the cross-national variations in suicidal tendencies to explain the incidence of suicide and non-suicide terrorist attacks worldwide from 1991 to 2014. Results revealed that countries with higher share of deaths from suicide displayed higher incidences of suicide attacks but similar incidences of non- suicide attacks. The decision of some terrorists to sacrifice their life may well have been subject to over-theorization.

Demonstrate Values: Behavioral Displays of Moral Outrage as a Cue to Long-term Mate Potential

Brown, Mitch, Lucas A. Keefer, Donald F. Sacco, and Faith L. Brown. 2020. “Demonstrate Values: Behavioral Displays of Moral Outrage as a Cue to Long-term Mate Potential.” PsyArXiv. May 22. doi:10.31234/osf.io/qc8sk

Abstract: Recent findings suggest that moral outrage serves an interpersonal function of signaling trustworthiness to others and such perceptions play a uniquely important role in identifying social opportunities. We conducted four studies investigating how behavioral displays of moral outrage are perceived in the specific context of mating. Results indicated participants (particularly women) found prospective mates espousing outrage more desirable for long-term mating (Study 1), and this perception of desirability was similarly inferred among same-sex raters (Study 2). We further replicated findings in Study 1, while additionally considering the basis of women’s attraction toward outraged behavior through candidate mediators (Studies 3 and 4). Although we found consistent evidence for the long-term desirability of outraged behavior, in addition, to trustworthiness, evidence remained mixed on the extent to which evaluations of a prospective mate’s outrage was the basis of effects. We frame results from complementary perspectives of trust signaling and sexual strategies theory.
