Building public will for climate action requires designing messages for different audiences. Previous studies that identified groups based on similar beliefs, behavior, and political preferences related to climate change were in single countries and were not pre-registered. The current study ran latent class analysis on the European Social Survey (...
Article
Full-text available
The adoption of sustainable lifestyles plays a key role in mitigating climate change. Previous research has found that social norms—beliefs about what most people do and approve of—profoundly impact individual engagement in pro-environmental behaviour. However, little is known about personal and contextual factors that moderate social norm interven...

Climate change is currently one of humanity’s greatest threats. To help scholars understand the psychology of climate change, we conducted an online quasi-experimental survey on 59,508 participants from 63 countries (collected between July 2022 and July 2023). In a between-subjects design, we tested 11 interventions designed to promote climate chan...

Effectively reducing climate change requires dramatic, global behavior change. Yet it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an e...

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures...
Article
Full-text available
The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in t...
Article
Full-text available
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...
Article
Full-text available
Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these...

Economic inequality is associated with extreme preferences for smaller, immediate gains over larger, delayed ones. This pattern, known as temporal discounting, may feed into rising global inequality, yet it is unclear if it is a function of choice preferences or norms, or rather the absence of sufficient resources to meet immediate needs. It is als...

Economic inequality is associated with extreme rates of temporal discounting, which is a behavioral pattern where individuals choose smaller, immediate financial gains over larger, delayed gains. Such patterns may feed into rising global inequality, yet it is unclear if they are a function of choice preferences or norms, or rather absence of suffic...

Effectively motivating social distancing—keeping a physical distance from others —has become a global public health priority during the COVID-19 pandemic. This cross-country preregistered experiment (n=25,718 in 89 countries) tested hypotheses derived from self-determination theory concerning generalizable positive and negative outcomes of differen...
Article
Full-text available
Pervading global narratives suggest that political polarization is increasing, yet the accuracy of such group meta-perceptions has been drawn into question. A recent US study suggests that these beliefs are inaccurate and drive polarized beliefs about out-groups. However, it also found that informing people of inaccuracies reduces those negative be...
Article
Full-text available
In recent years, interest in the psychology of fake news has rapidly increased. We outline the various interventions within psychological science aimed at countering the spread of fake news and misinformation online, focusing primarily on corrective (debunking) and pre-emptive (prebunking) approaches. We also offer a research agenda of open questio...
Preprint
A pervading global narrative suggests that political polarisation is increasing in the US and around the world. Beliefs in increased polarisation impact individual and group behaviours regardless of whether they are accurate or not. One driver of polarisation are beliefs about how members of the out-group perceive us, known as group meta-perception...
Chapter
The most pressing environmental concerns of the twenty-first century include climate change, sustainable energy production, and access to clean air and water. Effective energy and environmental policies are needed beyond polarized debates around regulation.This is problematic as it is also widely argued that the public is simply not compelled by cl...

Three ways of achieving happiness—life of pleasure, life of engagement, and life of meaning (Seligman, 2002)—have been examined among adult samples. However, very few studies have investigated these orientations to happiness in non-adult populations. Numerous studies have found that different ways of spending leisure time affect the psychological w...
