A “big data” study found maintaining a moral is one of most important values. In making hypothetical choices, high percentages “normal” reported preferring jail time, amputation limbs, death various forms (i.e.,...

Women can offer sex or exclusive access to men exchange for resources. compete by enhancing physical appearance denigrating rivals' reputations. Men both individually groups amass resources sex.

Social technology is ever-evolving, and increasingly offers novel domains for sexual experiences. In the current study, we investigated demographic correlates of engagement with emerging forms sextech, defined here as internet-based applications, platforms, or devices used pleasure. Our web-based, demographically representative sample included 7,512 American adults aged 18–65 years, a near-even gender split men/women moderate racial diversity (63% White). Participants indicated their eight...
Here, we present a mechanistically grounded theory detailing novel function of the behavioral immune system (BIS), psychological that prompts pathogen avoidance behaviors. We propose BIS activity allows body to downregulate basal inflammation, preventing resultant oxidative damage DNA and promoting longevity. Study 1 investigated relationship between trait measure motivation in vitro vivo proinflammatory cytokine production. 2 examined this same predictor often associated with prolonged...
Grief is a puzzling phenomenon. It often costly and prolonged, potentially increasing mortality rates, drug abuse, withdrawal from social life, susceptibility to illness. These costs cannot be repaid by the deceased therefore might appear wasted. In following article, we propose possible solution. Using principles of selection theory, argue that an important selective pressure behind human grief response was decisions other humans. We combine this with insights signaling noting shares many...
The contemporary culture of harm avoidance sanctifies the role victim, which creates a suite challenges for managers and researchers attempting to address impartially allegations harmdoing. We contend that victimhood sanctification compromises our understanding mistreatment largely due three forces: 1) shift toward hypersensitivity, expands definition mistreatment, 2) cognitive shortcuts cast actors as either victims or perpetrators, 3) victims' in experiencing perceiving mistreatment. Of...
Abstract Scientific and organizational interventions often involve trade-offs whereby they benefit some but entail costs to others (i.e., instrumental harm; IH). We hypothesized that the gender of persons incurring those would influence intervention endorsement, such people more readily support inflicting IH onto men than women. also women exhibit greater asymmetries in their acceptance versus Three experimental studies (two pre-registered) tested these hypotheses. Studies 1 2 granted for...
Research indicates that antigay bias follows a specific pattern (and probably has throughout written history, at least in the West): (a) men evince more than women; (b) who belong to traditionally male coalitions those do not; (c) is targeted gay lesbians; and (d) effeminate masculine men. We propose coalitional value theory (CVT) of explain this pattern. The CVT argues evolved psychological systems facilitate formation regulation these may lead because perceive as possessing lower for...
Despite organizations' professed commitment to fairness, thousands of employees file race-based discrimination claims every year. The current article examines how people deviate from impartiality when evaluating candidates in hiring decisions. Researchers have argued the ideological endorsement elitism (i.e., scoring high social dominance orientation) can lead against racial minorities. We examined whether an opposing commitment-egalitarianism-can also produce partiality, but favor minority...
Depression, anxiety, and loneliness have long been recognized as global mental health concerns. To temporarily relieve psychological distress, self-soothing behavior is common, including engagement in sexual behaviors that are linked to positive well-being. Considering the COVID-19 pandemic further exacerbated many ailments alongside physical distancing regulations, we specifically examined online via use of emergent digital technologies, or sextech. In a 2019 study 8004 American adults,...
People tend to befriend others similar themselves, generating a pattern called homophily. However, existing studies on friendship patterns often rely surveys that assess the perspective of relatively few participants their friendships but do not measure actualized patterns. Here, we used data from large Slovakian online social network role gender, age, and body mass index (BMI) in same-gender connections among more than 400,000 users. We found age BMI homophily occurred both men's women's...
