Abstract [en]

Far from all who complete teacher education end up working as teachers throughout their entire career. At first sight the value of teacher education, in terms of efficiency, seems to be a failure. In the present article we argue that teacher attrition, when defined as whether one is working as teacher or not, is a too blunt measure to gauge whether teacher education has been valuable. With a unique dataset, where we have detailed information on 87 Swedish teacher graduates’ working life across 23 years, we can consider whether activities and/or experiences point to an apparent use of teacher education. In conclusion, we find that in order to get informative estimates of its value it is important to consider it from different perspectives and to consider attrition related to the total working time spent in educational settings across a career rather than percentage leaving teaching after a set of years.

Abstract [en]

The usefulness of conveying descriptive norms (“this is what most people do”) for prosocial purposes such as environmental conservation and charitable giving has recently been called into question. Two experiments (N = 748) evaluated the hypothesis that descriptive norms increase people's intentions to donate to charity. Overall, the results supported this hypothesis. Another aim was to examine the robustness of the local norm superiority effect that proposes that the local norms of one's immediate environment are superior to other descriptive norms (global and social identity norms). This hypothesis was not supported. The results suggest that differences between different types of norms are likely to be small.

Abstract [en]

A central question in social psychology is to what extent individual differences in attitudes, prejudices, and stereotypes can predict discriminatory behavior. This is often studied by simply regressing a measure of behavior toward a single group (e.g., behavior toward Black people only) onto the predictors (e.g., attitude measures). In the present paper, we remind researchers that an analysis focusing on predicting the differential treatment (e.g., behavior towards Black people vs. White people) has a higher conceptual validity and will result in more informative effect sizes. The paper is concluded with a list of suggestions for future research on the link between attitudes, prejudices, stereotypes and discrimination.

Abstract [en]

In response to recommendations to redefine statistical significance to P ≤ 0.005, we propose that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.

Abstract [en]

Twenty-nine teams involving 61 analysts used the same dataset to address the same research question: whether soccer referees are more likely to give red cards to dark skin toned players than light skin toned players. Analytic approaches varied widely across teams, and estimated effect sizes ranged from 0.89 to 2.93 in odds ratio units, with a median of 1.31. Twenty teams (69%) found a statistically significant positive effect and nine teams (31%) observed a non-significant relationship. Overall 29 differentanalyses used 21 unique combinations of covariates. We found that neither analysts' prior beliefs about the effect, nor their level of expertise, nor peer-reviewed quality of analysis readily explained variation in analysis outcomes. This suggests that significant variation in the results of analyses of complex data may be difficult to avoid, even by experts with honest intentions. Crowdsourcing data analysis, a strategy by which numerous research teams are recruited to simultaneously investigate the same research question, makes transparent how defensible, yet subjective analytic choices influence research results.

Abstract [en]

The present study investigated the relative importance of two explanations behind perceptions of gender discrimination in hiring: prototypes and same- gender bias. According to the prototype explanation, people perceive an event as discrimination to the extent that it fits their preconceptions of typical discrimination. In contrast, the same-gender bias explanation asserts that people more readily detect discrimination toward members of their own gender. In four experiments (n = 797), women and men made considerably stronger discrimination attributions, and were moderately more discouraged from seeking work, when the victim was female rather than male. Further, a series of regressions analyses showed beliefs in discrimination of women to be moderately correlated with discrimination attributions of female victims, but little added explanatory value of participant gender, stigma consciousness, or feminist identification. The results offer strong support for the prototype explanation.

Abstract [en]

A cross-national study, 49 samples in 38 nations (n = 4,344), inves- tigates whether national peace and conflict reflect ambivalent warmth and competence stereotypes: High-conflict societies (Pakistan) may need clearcut, unambivalent group images distinguishing friends from foes. Highly peaceful countries (Denmark) also may need less ambivalence because most groups occupy the shared national identity, with only a few outcasts. Finally, nations with interme- diate conflict (United States) may need ambivalence to justify more complex intergroup-system stability. Using the Global Peace Index to measure conflict, a curvilinear (quadratic) relationship be- tween ambivalence and conflict highlights how both extremely peaceful and extremely conflictual countries display lower stereo- type ambivalence, whereas countries intermediate on peace-conflict present higher ambivalence. These data also replicated a linear inequality–ambivalence relationship.

Abstract [en]

Scheibehenne, Jamil, and Wagenmakers (2016; SJW) recently introduced Bayesian evidence synthesis (BES). They used it to combine evidence from seven published studies that examined the influence of social-norm messages on hotel towel reuse rates. Although most of the original studies provided non-significant results (p-value > .05), BES provided strong support for the effect (Bayes factor = 37). We think that this conclusion is wrong. We demonstrate that BES is inherently flawed because it pools data in a way that is vulnerable to a Simpson’s paradox, and that a Bayesian meta-analysis that avoids this problem produces weaker evidence.

Abstract [en]

Developmental studies of hormones and behavior often include littermates—rodent siblings that share early-life experiences and genes. Due to between-litter variation (i.e., litter effects), the statistical assumption of independent observations is untenable. In two literatures—natural variation in maternal care and prenatal stress—entire litters are categorized based on maternal behavior or experimental condition. Here, we (1) review both literatures; (2) simulate false positive rates for commonly used statistical methods in each literature; and (3) characterize small sample performance of multilevel models (MLM) and generalized estimating equations (GEE). We found that the assumption of independence was routinely violated (>85%), false positives (α = 0.05) exceeded nominal levels (up to 0.70), and power (1−β) rarely surpassed 0.80 (even for optimistic sample and effect sizes). Additionally, we show that MLMs and GEEs have adequate performance for common research designs. We discuss implications for the extant literature, the field of behavioral neuroendocrinology, and provide recommendations.
