- Although the use of manipulation checks is widespread in social psychology, several researchers have raised methodological concerns about their use and interpretations. However, knowledge of how they are actually being used has been lacking. Extracting data from published reports of 207 recent experiments, we provide an empirical review of current practices concerning manipulation checks in social psychology. Our review suggests that there are serious deficiencies in the manner in which manipulation checks are used and interpreted. For example, published reports tend to contain highly limited quantitative reasoning about the effectiveness of manipulations, and researchers report little or nothing to address the possibility that manipulation checks might cause undesirable reactivity among participants. However, we argue that manipulation checks can be highly beneficial components of experiments when used properly, and they have untapped potential for the quantitative assessment of the strength of manipulations relative to the effect on the dependent variable (i.e., causal efficacy). To assist with such assessments, we provide empirical benchmarks for causal efficacy in social psychology. Additionally, we provide several recommendations for researchers and reviewers for improving the use and reporting of manipulation checks.

- How does war shape human altruism? Some find warfare increases generosity within groups only. Others maintain that war’s prosocial effects extend to outgroup members as well. To make sense of these disparate findings, we offer a theoretical framework that highlights the role of threat sensitivity in altruism. Refugees from Syria and Iraq (N = 1521) completed a welfare tradeoff task and threat perceptions scale where the other's group identity, gender and age were experimentally varied. We found that individuals belonging to social categories associated with more threat (outgroup members, males, and younger individuals) were afforded less altruism compared to individuals belonging to non-threatening social categories (ingroup members, females and the elderly). War exposure enhanced bias against threatening social categories through increased threat-sensitivity. Our results have implications for understanding how warfare shapes altruism and welfare tradeoffs in light of cross-cutting social categories and for policies promoting post-conflict cooperation.

- How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design in addition to the original ones, to help determine which theory best accounts for the results across multiple key outcomes and contexts. The present pre-registered empirical project compared the Implicit Puritanism account of intuitive work and sex morality to theories positing regional, religious, and social class differences; explicit rather than implicit cultural differences in values; self-expression vs. survival values as a key cultural fault line; the general moralization of work; and false positive effects. Contradicting Implicit Puritanism's core theoretical claim of a distinct American work morality, a number of targeted findings replicated across multiple comparison cultures, whereas several failed to replicate in all samples and were identified as likely false positives. No support emerged for theories predicting regional variability and specific individual-differences moderators (religious affiliation, religiosity, and education level). Overall, the results provide evidence that work is intuitively moralized across cultures.

Tears evoke the intention to offer social support : A systematic investigation of the interpersonal effects of emotional crying across 41 countries

- Tearful crying is a ubiquitous and likely uniquely human phenomenon. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by evoking social support intentions. Initial experimental studies supported this proposition across several methodologies, but these were conducted almost exclusively on participants from North America and Europe, resulting in limited generalizability. This project examined the tears-social support intentions effect and possible mediating and moderating variables in a fully pre-registered study across 7007 participants (24,886 ratings) and 41 countries spanning all populated continents. Participants were presented with four pictures out of 100 possible targets with or without digitally-added tears. We confirmed the main prediction that seeing a tearful individual elicits the intention to support, d = 0.49 [0.43, 0.55]. Our data suggest that this effect could be mediated by perceiving the crying target as warmer and more helpless, feeling more connected, as well as feeling more empathic concern for the crier, but not by an increase in personal distress of the observer. The effect was moderated by the situational valence, identifying the target as part of one's group, and trait empathic concern. A neutral situation, high trait empathic concern, and low identification increased the effect. We observed high heterogeneity across countries that was, via split-half validation, best explained by country-level GDP per capita and subjective well-being with stronger effects for higher-scoring countries. These findings suggest that tears can function as social glue, providing one possible explanation why emotional crying persists into adulthood.
