The Link Between Self-Dehumanization and Immoral Behavior. Maryam Kouchaki et al.
Psychological Science, https://doi.org/10.1177/0956797618760784
Abstract: People perceive morality to be distinctively human, with immorality representing a lack of full humanness. In eight experiments, we examined the link between immorality and self-dehumanization, testing both (a) the causal role of immoral behavior on self-dehumanization and (b) the causal role of self-dehumanization on immoral behavior. Studies 1a to 1d showed that people feel less human after behaving immorally and that these effects were not driven by having a negative experience but were unique to experiences of immorality (Study 1d). Studies 2a to 2c showed that self-dehumanization can lead to immoral and antisocial behavior. Study 3 highlighted how self-dehumanization can sometimes produce downward spirals of immorality, demonstrating initial unethical behavior leading to self-dehumanization, which in turn promotes continued dishonesty. These results demonstrate a clear relationship between self-dehumanization and unethical behavior, and they extend previous theorizing on dehumanization.

Sex differences in navigation strategy and efficiency
Sex differences in navigation strategy and efficiency. Alexander P. Boone, Xinyi Gong, Mary Hegarty. Memory & Cognition, https://link.springer.com/article/10.3758/s13421-018-0811-y
Abstract: Research on human navigation has indicated that males and females differ in self-reported navigation strategy as well as objective measures of navigation efficiency. In two experiments, we investigated sex differences in navigation strategy and efficiency using an objective measure of strategy, the dual-solution paradigm (DSP; Marchette, Bakker, & Shelton, 2011). Although navigation by shortcuts and learned routes were the primary strategies used in both experiments, as in previous research on the DSP, individuals also utilized route reversals and sometimes found the goal location as a result of wandering. Importantly, sex differences were found in measures of both route selection and navigation efficiency. In particular, males were more likely to take shortcuts and reached their goal location faster than females, while females were more likely to follow learned routes and wander. Self-report measures of strategy were only weakly correlated with objective measures of strategy, casting doubt on their usefulness. This research indicates that the sex difference in navigation efficiency is large, and only partially related to an individual’s navigation strategy as measured by the dual-solution paradigm.

From 2016, a way to detect psychopaths: Stable individual differences in moral behavior can be systematically observed in daily life, and that their stability is comparable to the stability of neutral language behavior
From 2016: Eavesdropping on Character, Assessing Everyday Moral Behaviors. Kathryn L. Bollich et al. J Res Pers. 2016 Apr; 61: 15–21. DOI 10.1016/j.jrp.2015.12.003
Abstract: Despite decades of interest in moral character, comparatively little is known about moral behavior in everyday life. This paper reports a novel method for assessing everyday moral behaviors using the Electronically Activated Recorder (EAR)—a digital audio-recorder that intermittently samples snippets of ambient sounds from people's environments—and examines the stability of these moral behaviors. In three samples (combined N = 186), participants wore an EAR over one or two weekends. Audio files were coded for everyday moral behaviors (e.g., showing sympathy, gratitude) and morally-neutral comparison language behaviors (e.g., use of prepositions, articles). Results indicate that stable individual differences in moral behavior can be systematically observed in daily life, and that their stability is comparable to the stability of neutral language behaviors.

Thirty years of sexual behaviour at a Canadian university: Romantic relationships, hooking up, and sexual choices... since at least 1990, the majority have been primarily monogamous
Thirty years of sexual behaviour at a Canadian university: Romantic relationships, hooking up, and sexual choices. Nancy S. Netting, Meredith K. Reynolds. The Canadian Journal of Human Sexuality, Volume 27 Issue 1, May 2018, pp. 55-68. https://doi.org/10.3138/cjhs.2017-0035
Abstract: Every 10 years from 1980 to 2010, students in a British Columbia university were surveyed about age of sexual initiation, number of partners, and degree of emotional intimacy within their partnerships. Between 1980 and 1990, the socially acceptable prerequisite for premarital sex appeared to shift from the promise of marriage to mutual love. This change was demonstrated by a fall in the virginity rate among unmarried females, and the rise of monogamous romantic relationships for males. From 1980 through 2010, men reported more sexual partners than did women, with a smaller, though rising, proportion of serious relationships. Since 1990, never-married students were classified into three sexual behavioural groups: monogamists (about 55%), abstainers (30%), and multi-partnered “experimenters” (20% of men throughout each decade, and 7.6% of women in 1990–2000, rising to 14.4% in 2010). Experimenters generally reported concurrent partners, most of them casual. Since 1980, most sexually active students have experienced both romantic relationships and casual sexual partnerships, yet since at least 1990, the majority have been primarily monogamous. This article traces the changes and continuities in romantic relationships, casual sex, and sexual behavioural groups over 30 years, concluding that contrary to the claims of popular media and some academics, casual sex (“hookup culture”) has not replaced romantic relationships as the most common form of student sexual behaviour.
KEY WORDS: Student sexual behaviour, romantic relationships, monogamy, hookup culture, casual sex, friends with benefits, sexual revolution, sexual scripts, emerging adulthood

Personality change among newlyweds: Declines in agreeableness for husbands and wives, declines in extraversion for husbands, declines in openness and neuroticism for wives, and increases in conscientiousness for husbands
Lavner, J. A., Weiss, B., Miller, J. D., & Karney, B. R. (2018). Personality change among newlyweds: Patterns, predictors, and associations with marital satisfaction over time. Developmental Psychology, 54(6), 1172-1185. http://dx.doi.org/10.1037/dev0000491
Abstract: The early years of marriage are a time of significant personal and relational changes as partners adjust to their new roles, but the specific ways that spouses’ personalities may change in early marriage and how these changes are associated with spouses’ marital satisfaction trajectories have been overlooked. Using 3 waves of data collected over the first 18 months of marriage (N = 338 spouses, or 169 heterosexual newlywed marriages), we examined changes in spouses’ self-reported Big 5 personality traits over time and the association between initial levels and changes in personality and spouses’ concurrent marital satisfaction trajectories. Results indicated significant changes in personality over time, including declines in agreeableness for husbands and for wives, declines in extraversion for husbands, declines in openness and neuroticism for wives, and increases in conscientiousness for husbands. These results did not differ by spouses’ age, demographics, relationship length prior to marriage, cohabitation prior to marriage, initial marital satisfaction, or parenthood status. Initial levels of personality as well as changes in personality over time were associated with spouses’ marital satisfaction trajectories. Taken together, these findings indicate that newlywed spouses’ personalities undergo meaningful changes during the newlywed years and these changes are associated with changes in spouses’ marital satisfaction. Further research is needed to understand the processes underlying changes in personality early in marriage and to examine the mechanisms linking changes in personality and changes in marital satisfaction.

Per political party: Americans' Attitudes on Individual or Racially Inflected Genetic Inheritance
Americans' Attitudes on Individual or Racially Inflected Genetic Inheritance. Jennifer Hochschild, Maya Sen. On Reconsidering Race: Social Science Perspectives on Racial Categories in the Age of Genomics.

From the Nov 2013 paper, about Importance of individual, and of racial or ethnic, genetic inheritance, by partisan affiliation:
Democrats and Republicans hold roughly similar views, while the category of Independents, Undecided, and “Other” differ systematically from both sets of partisans. With regard to racial or ethnic genetic inheritance (shaded columns), Independents are less likely than the other two groups to see racial inheritance in six of the eight characteristics. That includes the three items that are generally assumed to be heritable (eye color, sickle cell anemia, and cystic fibrosis), for which the Independents are arguably mistaken. But it also includes the more ambiguous category of intelligence.
With regard to individual genetic inheritance, Democrats and Republicans again resemble one another, while Independents differ. Setting aside homosexuality, Independents are again The least likely to make genetic attributions to the three genetically-linked traits, but they are most likely to make genetic attributions to the three ambiguous traits of heart disease, intelligence, and aggressiveness. Again, reassuringly we see no variation in the very low proportions attributing the flu to either type of inheritance.
We need further research to explain the anomaly of the Independents, and how or why partisanship relates to other possible associations (for example, education, gender, and race with views about genetic determinism. But these results conform to the general finding in the academic literature that “pure” Independents and nonpartisans (the Undecided or Others) are less knowledgeable about current events and political and social facts (Keith et al. 1992). The surprising and intriguing result is the lack of difference between Republicans and Democrats in the degree to which they concur with the social constructivist view, either with regard to racial or ethnic inheritance or individual ancestral inheritance. If the GKAP survey represents Americans in general, the question of biological or social causation is not polarized in the public in the way that it is among knowledgeable experts.
This similarity is reinforced by the overall average likelihood of making genetic attributions. As we have found in every previous analysis, for all items in all groups, there are fewer attributions to racial or ethnic inheritance than to individual ancestral inheritance. But within that framework, Republicans and Democrats closely resemble one another in accepting both types of genetic causes, while Independents are less likely to accept either individual genetic inheritance or, especially, racial or ethnic genetic inheritance. That is not what we expected, and it warrants further study.
The surprise deepens when we look only at the five items that are not generally understood as heritable. For those items, Independents are the most likely to make genetic attributions, both for individual ancestral inheritance and for group-based inheritance – but Democrats are more likely than Republicans to do so, again for both types of inheritance. Even setting aside the three items that are arguably not socially constructed, Republicans are closer to being social constructivists than are Democrats. In light of the normative valences with which this chapter started, that finding needs further exploration.
The Anomalous Case of Homosexuality: We have noted several times that responses to the item, “being gay or lesbian,” differ from responses to the other three traits (heart disease, intelligence, and a tendency toward violence) for which genetic and environmental or choice-based explanations are more ambiguous. We turn finally to a direct consideration of this item. Hypothesis H5.5 posits that views on homosexuality are an exception to our overall expectation about the link between partisanship (or ideology) and social constructivism, and that is indeed the case. As table 5 shows, Democrats are much more likely than Independents or Republicans to attribute being gay or lesbian to “genes,” and slightly more likely to attribute being gay or lesbian to “race or ethnicity.” Indeed, Democrats’ relatively high agreement with “genes” for that item helps to explain the fact that overall they are less socially constructivist than Republicans.10 [10 It does not fully explain that surprising result, however, since Democrats are also just as likely or slightly more likely than Republicans to explain heart disease, intelligence, and aggression through genetic causes]
