A synthesis of evidence for policy from behavioural science during COVID-19.

Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations ('claims') detailing how evidence from behavioural science could contribute to efforts to reduce impacts and end the COVID-19 pandemic. Here we assess 747 pandemic-related research articles that empirically investigated those claims. We report the scale of evidence and whether evidence supports them to indicate applicability for policymaking. Two independent teams, involving 72 reviewers, found evidence for 18 of 19 claims, with both teams finding evidence supporting 16 (89%) of those 18 claims. The strongest evidence supported claims that anticipated culture, polarization and misinformation would be associated with policy effectiveness. Claims suggesting trusted leaders and positive social norms increased adherence to behavioural interventions also had strong empirical support, as did appealing to social consensus or bipartisan agreement. Targeted language in messaging yielded mixed effects and there were no effects for highlighting individual benefits or protecting others. No available evidence existed to assess any distinct differences in effects between using the terms 'physical distancing' and 'social distancing'. Analysis of 463 papers containing data showed generally large samples; 418 involved human participants with a mean of 16,848 (median of 1,699). That statistical power underscored improved suitability of behavioural science research for informing policy decisions. Furthermore, by implementing a standardized approach to evidence selection and synthesis, we amplify broader implications for advancing scientific evidence in policy formulation and prioritization.

The connections between personality, ideology and (counter-)empathic emotions depend on the target.

OBJECTIVES: Examine the group-specific connections between personality, ideology, and the moral emotions of empathy and schadenfreude. BACKGROUND: Empathy and schadenfreude are emotions that often lead to moral prosocial or spiteful harmful behaviors respectively. An outstanding question is what motivates feelings of empathy and schadenfreude towards people from different groups. Here we examine two prominent motivators of emotions: personality traits and ideology. Previous work has found that people's ideological orientations towards respecting traditionalism (RWA) and preferences about group-based hierarchy (SDO) can impact intergroup emotions. Further, personality traits of low agreeableness, low openness, and high conscientiousness uniquely engender SDO and RWA. METHOD: In the research presented here (Study 1 n = 492; Study 2 n = 786), we examine the relationships between personality traits, ideology, and emotions for groups that are perceived to be dangerous and competitive. We hypothesize that SDO and RWA will relate to reduced empathy and increased schadenfreude but towards unique groups. SDO will relate to reduced empathy and increased schadenfreude towards competitive, low-status groups while RWA will relate to reduced empathy and increased schadenfreude towards threatening groups. We further extend past work by investigating left-wing authoritarianism as well. RESULTS: We find broad support for our expectation that the relationships between personality and emotions, as well as ideology and emotions, depend on the specific group in question. CONCLUSIONS: These results help expand the dual process motivational model of prejudice and suggest the importance of specifying a target group when assessing relationships between personality, ideology, and emotions.

Investigating hair cues as a mechanism underlying Black women's intersectional invisibility.

Children psychologically exclude Black women from their representations of women, but the mechanisms underlying this marginalization remain unclear. Across two studies (N = 129; 49 boys, 78 girls, two gender unreported; 79 White, 27 Black, six Latinx, five Asian, and 12 unreported), the present work tests hair texture as one possible perceptual mechanism by which this might occur. In both studies, children gender-categorized Black, White, and Asian men and women using MouseTracker. Children were slower and had more complex patterns in categorizing Black women when they had textured hair (Study 1A), but not when they had straight hair (Study 1B). Implications for the development of gender as a social category are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The Pandemic as a Portal: Reimagining Psychological Science as Truly Open and Inclusive.

Psychological science is at an inflection point: The COVID-19 pandemic has exacerbated inequalities that stem from our historically closed and exclusive culture. Meanwhile, reform efforts to change the future of our science are too narrow in focus to fully succeed. In this article, we call on psychological scientists-focusing specifically on those who use quantitative methods in the United States as one context for such conversations-to begin reimagining our discipline as fundamentally open and inclusive. First, we discuss whom our discipline was designed to serve and how this history produced the inequitable reward and support systems we see today. Second, we highlight how current institutional responses to address worsening inequalities are inadequate, as well as how our disciplinary perspective may both help and hinder our ability to craft effective solutions. Third, we take a hard look in the mirror at the disconnect between what we ostensibly value as a field and what we actually practice. Fourth and finally, we lead readers through a roadmap for reimagining psychological science in whatever roles and spaces they occupy, from an informal discussion group in a department to a formal strategic planning retreat at a scientific society.
