Many charities rely on donations to support their work addressing some of the world’s most pressing problems. We conducted a meta-review to determine what interventions work to increase charitable donations. We found 21 systematic reviews incorporating 1339 primary studies and over 2,139,938 participants. Our meta-meta-analysis estimated the averag...

Transitioning toward plant-based diets can alleviate health and sustainability challenges. However, research on interventions that influence animal-product consumption remains fragmented and inaccessible to researchers and practitioners. We conducted an overview of systematic reviews, also known as a meta-review. We searched five databases for revi...

PurposeResponding to worldwide pandemics, such as the recent COVID-19, requires the general public to comply with recommended health-protective behaviours at early stages of the spread of the virus. MethodologyThe current study of 1,211 Australians aimed to investigate whether confidence in political and health authorities predicted intention to ad...

Risk taking is typically viewed through a lens of individual deficits (e.g., impulsivity) or normative influence (e.g., peer pressure). An unexplored possibility is that shared group membership, and the trust that flows from it, may play a role in reducing risk perceptions and promoting risky behavior. We propose and test a Social Identity Model of...

Background: Mass gatherings are well-documented for their public health risks; however, little research has examined their impact on mental health or focused on young people specifically. This study explores risk and protective factors for mental health at mass gatherings, with a particular focus on characterising attendees with high levels of psy...

We examined two threats to belonging and related needs on Facebook: lurking (Study 1) and ostracism (Study 2). In Study 1, participants were either allowed or not allowed to share information on Facebook for 48 hours. Those who were not allowed to share information had lower levels of belonging and meaningful existence. In Study 2, participants eng...

Members of groups in conflict may take collective action: actions to improve conditions for their group as a whole. The psychological antecedents of collective action for groups that are party to conflict and inequality are well-established. Comparatively little is known about how uninvolved outsiders respond to an external intergroup conflict. We...

The present research adopts an extended theory of planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N=119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implic...

Purpose: Anecdotal evidence suggests that some sunglass users prefer yellow tints for outdoor activities such as driving, and research has suggested that such tints improve the apparent contrast and brightness of real-world objects. The aim of this study was to establish whether yellow filters resulted in objective improvements in performance for v...

In three experiments, we manipulated procedural fairness (Experiment 1) and group-based anger and group efficacy (Experiments 2 and 3) to investigate the independent pathways of anger and efficacy for collective action in China. In Experiment 3 we also examined pathways to “soft” (low-cost) and “hard” (high-cost) collective action. Our results supp...

Background: The importance of social connectedness in supporting public mental health is well established. However, the reverse causal pathway (that psychological ill-health leads to reduced social connectedness) remains a dominant perspective among mental health practitioners. Our analysis aimed to provide a rigorous test of the directionality of...

In three studies, we build on Schwartz’s (1992, 1994) work on universal values to explore the content and structure of individuals’ change and status quo values, to distinguish these values from other political ideologies and orientations, and to investigate the role of these values in shaping appraisals of intergroup conflict and collective action...

We are grateful to the editors for this stimulating opportunity to reflect on the nature of causality in our field, focusing on the social psychology of collective action and political behavior. Harré and Moghaddam in their introductory chapter of this volume identify a number of dimensions along which causality may be mapped, and we shall follow t...
