A megastudy of behavioral interventions to catalyze public, political, and financial climate advocacy
Addressing climate change depends on large-scale system changes, which require public advocacy. Here, we identified and tested 17 expert-crowdsourced theory-informed behavioral interventions designed to promote public, political, and financial advocacy in a large quota-matched sample of US residents (n = 31,324). The most consistently effective intervention emphasized both the collective efficacy and emotional benefits of climate action, increasi…
Gaps in public perceptions of extreme heat highlight UK’s lack of preparedness
Under a changing climate, heatwaves are expected to become more frequent, prolonged and extreme, posing substantial risks to populations around the world. Public perceptions of extreme heat are chronically under-researched, despite being important precursors to heat protective actions, policy acceptance and community heat resilience. We present and discuss findings from a nationally representative survey of 1750 UK residents conducted in summer 2…
Addressing climate change with behavioral science
Effectively reducing climate change requires marked, global behavior change. However, 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 effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interve…
The power of protest in the media
Over the last several years, the United Kingdom has seen a wave of environmental movements demanding action on the climate crisis. While aligned in their goals, the groups undertaking this activism often diverge on the question of tactics. One such divergence occurred in January 2023, when Extinction Rebellion (XR) declared “We Quit”, ending actions that were disruptive to the general public. Peer groups Just Stop Oil and Animal Rising continued …

We study the wellbeing returns from volunteering in England's National Health Service (NHS) Volunteer Responders, set up in response to Covid-19. Using linked survey and administrative data, we exploit the oversubscription of volunteers and the random allocation of tasks via an app to establish causality. Volunteers show stronger wellbeing and feelings of belongingness and connectedness to their local area. Welfare analyses suggest that the benef…
Sticky brown sludge everywhere
Behavioural science has sought to promote pro-environmental behaviours including climate-friendly dietary change, and to reduce travel emissions and excessive wastes. Nevertheless, there is a debate about how effective behavioural interventions are, and in turn, about the real barriers to enduring pro-environmental behaviour change. In this context, we conceptualise brown sludge as multi-level impediment to pro-environmental behaviour change, whi…
Public support for degrowth policies and sufficiency behaviours in the United States
The causal revolution in biodiversity conservation
Changing behavioral responses to heat risk in a warming world
Heat risks, such as those associated with heatwaves, are increasing in frequency, severity, and duration due to climate change. The ways in which people around the globe perceive and respond to heat risks are now of great importance to reduce a range of negative health outcomes. A growing body of literature aims to assess the factors that influence people's behaviors in relation to heat risks. This research can inform better interventions, such a…
Effective carbon taxes need green nudges
Public support for ‘soft’ versus ‘hard’ public policies
This article reviews the literature on public support for ‘soft’ versus ‘hard’ policy instruments for behaviour change, and the factors that drive such preferences. Soft policies typically include ‘moral suasion’ and educational campaigns, and more recently behavioural public policy approaches like nudges. Hard policy instruments, such as laws and taxes, restrict choices and alter financial incentives. In contrast to the public support evidenced …
Experimental Evidence on the Impact of Biodiversity Conservation Videos on Charitable Donations
We explored how different types of audio-visual media content impacted charitable donations using a lab experiment. Subjects chose to donate to a charity in a modified dictator game, after being randomly assigned to watch videos featuring either a non-charismatic species (Bats), a charismatic species (Lions) a composite habitat composed of both species (Bats and Lions in the Savanna), with and without additional content on the anthropogenic cause…
