Expressing gratitude often strengthens relationships, yet many people say "thank you" despite not feeling especially grateful. Although this may seem innocuous, are there hidden costs? We tested the effects of expressed, perceived, and accurate perceptions of gratitude amplification on romantic couples' personal and relational well-being across four dyadic studies (N_couples = 639), including lab conversations (Studies 1a and 2a), naturalistically in daily life (Studies 1b and 2b), and over time (Studies 3 and 4). Findings indicated that higher expressed and perceived gratitude amplification did yield personal and interpersonal costs, which were mediated by lower authenticity and responsiveness. Effects could not be accounted for by alternative explanations, including expressers feeling lower relationship satisfaction or less grateful for their partner. Altogether, we identify a hidden cost of gratitude expressions, indicating that amplified gratitude can undermine couples' well-being by compromising authenticity and responsiveness.

Personality traits drive people's financial decisions and hence affect their lives. Yet, we know little about the relationship between personality traits and insurance decisions. Do Risk-Taking, the Big Five and Locus of Control predict a variety of personal insurance decisions? Using a sample of 14,624 German adults with the goal of identifying associations between personality and insurance demand, we found that personality traits predict demand for various insurance types. We also found that associations may be mediated by demographic variables and may depend on the statistical modeling approach (e.g., including nonlinear relationships or examining between- and within-person effects). These findings contribute to our understanding of the role of personality in insurance demand and highlight the need for further exploration of this relationship, as our results demonstrate that personality-insurance-demand-associations depend on the examined insurance type.

Extending research that people are able to predict the patterns of their social group biases on Implicit Association Tests (IATs), we let participants predict and complete IATs toward five different food item pairs and compared the results with the social-groups domain. Participants predicted the patterns of their IAT scores with similar accuracy in both domains, suggesting similar internal awareness (evidenced by comparable within-subjects correlations), even though food evaluations followed less descriptively-normative patterns. At the same time, participants were better-calibrated in communicating their evaluations in the domain of food than social groups (evidenced by higher between-subjects correlations). This discrepancy may partly stem from participants' tendency to refrain from using harsh labels when predicting social group biases, despite their demonstrated awareness of them: IAT scores predicted as "moderate" or "strong" for food preferences tended to be labeled "mild" for social groups. Discussion centers on the importance of distinguishing between awareness and calibration.

Most Five-Factor Model (FFM) questionnaire items contain unique variance that is partly heritable, stable, and consensually observable, demonstrates consistent associations with age and sex, and predicts life outcomes beyond higher order factors. Extending these findings to the HEXACO model, we meta-analyzed single-item cross-rater agreement, heritability, and 2-year stability using samples from six countries. We analyzed raw item scores and their residual variance and adjusted the estimates for measurement unreliability. The median cross-rater agreement, heritability, and stability estimates were, respectively, .30, .30, and .57, for raw items and .10, .16, and .39, for item residuals. Adjusted for reliability, the respective medians were .46 and .25 for cross-rater agreement, .46 and .39 for heritability, and .87 and .94 for stability. These results are strikingly consistent with FFM-based findings, providing nondismissible evidence that single items index a partly unique level of the trait hierarchy-personality nuances-with trait properties comparable to those of higher-order traits.

We explore whether societal gender stereotypes re-emerge as social information is repeatedly passed from person to person. We examined whether peoples' memories of personality attributes associated with female and male social targets became increasingly consistent with societal gender stereotypes as information was passed down social transmission chains. After passing through the memories of just four generations of participants, our initially gender-balanced micro-societies became rife with traditional gender stereotypes. While we found some evidence of the re-emergence of gender stereotypes in Experiment 1, we found the effects were stronger when targets appeared in a feminine-stereotyped occupational context (Experiment 2), and a masculine-stereotyped occupational context (Experiment 3); conversely, the re-emergence of gender stereotypes was attenuated when targets appeared in a single gender context (Experiment 4). The current findings demonstrate that gender schematic memory bias, if widely shared, might cause gender stereotypes to be maintained through cultural evolution.

In Western societies, singlehood has become increasingly normative over historical time. But whether singles are more satisfied nowadays remains unclear. In this preregistered cohort-sequential study, we analyzed data from 2,936 German participants (M = 21.01 years, SD = 7.60 years) from different birth cohorts. Singlehood satisfaction and life satisfaction were reported annually at two different time periods (2008-2011 and 2018-2021). This design allowed us to compare earlier-born and later-born singles during adolescence (14-20 years), emerging adulthood (24-30 years), and established adulthood (34-40 years). Results from multilevel growth-curve models indicated that adolescent singles born in 2001 to 2003 (vs. 1991-1993) were more often single and more satisfied with singlehood. No cohort-related differences emerged among emerging and established adults. Younger age and lower neuroticism predicted higher satisfaction, regardless of birth cohort. The results highlight the importance of considering both societal and individual factors to understand singles' satisfaction.

Honor cultures are characterized by a heightened sensitivity to reputation threats and strong expectations for the defense of honor. U.S. states vary in the extent to which they express the cultural norms of honor, but researchers have frequently relied upon a dichotomous classification that differentiates states as honor or dignity states. We created and validated a continuous, six-item index of honor norms and values across all U.S. states (Study 1). In Study 2, our honor index was correlated with historical variables theoretically associated with the genesis of honor cultures. In Study 3, we validated our honor index further by showing that it predicted several race-/ethnicity-specific outcomes that prior research has connected with honor (e.g., homicide rates, suicide rates). This new index equips researchers with a more nuanced understanding of U.S. honor cultures and a measure that can be used in future investigations.

High-status group members typically respond defensively when their ingroup members transgress against low-status groups. However, when they identify highly with transgressor groups, they sometimes also engage in solidarity with victimized low-status groups due to ingroup-focused motives. Yet, the response of low-identified transgressor group members, who can prioritize victims' plight over ingroup interests, remains underexplored. To address this gap, we conducted three preregistered studies (N_total = 886) concerning education-based transgressions in the Netherlands and the United Kingdom, employing cross-sectional (Study 1) and experimental designs (Studies 2-3). Supporting previous research, we found that high-identifiers engage in nonradical solidarity driven by ingroup image concerns and image-related emotions. Low-identifiers, however, engage in both nonradical and radical solidarity through perceived injustice and justice-related emotions. Our findings provide insights into the roots of high-status group collective action on behalf of low-status groups against intergroup transgressions. Theoretical and societal implications were discussed.

Perceiving the ingroup as spiritually formidable-with inner strength and conviction-is strongly associated with the will to self-sacrifice. Yet, its underlying mechanisms remain unclear. Across five studies, we test a mechanism through which spiritual formidability operates: collective narcissism-the belief that the ingroup is exceptional but not sufficiently recognized by others. A preliminary study showed that collective narcissism, but not ingroup satisfaction, predicted costly pro-group sacrifices. Studies 1a and 1b revealed that, among inmates belonging to street gangs or delinquent bands, the perceived spiritual formidability of the ingroup was associated with collective narcissism and willingness to engage in costly pro-group sacrifices. In addition, the effect of perceived spiritual formidability on costly sacrifices was mediated by collective narcissism. Study 2 replicated and extended the effects to self-sacrifice for religion among imprisoned jihadists. Finally, Study 3 offered causal evidence of the mediation among members of the general population.

People tend to remember information from which they chose better than information assigned to them-a pattern known as the self-choice effect. The present studies tested the hypothesis that choosing for another person also improves memory. Studies 1a and 1b found that choosing for self and choosing for others both enhance memory compared with having no choice. Study 2 found that choosing for others boosts memory regardless of the closeness of the other. Study 3 found no memory benefit of making easy or difficult choices for others, contrary to predictions. And in Study 4 choosing for others enhanced memory only for chosen items. A mini meta-analysis combining all studies supported the conclusion that choosing for others enhances memory on a par with choosing for oneself. These results suggest that the effects of choice on memory signify something other than self-reference, which we presume to be substantially reduced when choosing for others.
