The Psychology of Collective Climate Action: Building Climate Courage
How do we find the courage to act together against the climate crisis? This book weaves together real-life findings and examples from the socio-ecological movement with psychological research to show ...

Thanks, Alex! Directly saved and it's so true - to generate the answers we need to combat climate and environmental problems, we need (to fund) more research in social sciences.

However, our article includes a brief original study in which we distinguished various types of activist behaviour (protester, change agent, educator, reformer) that may explain diverging findings in certain predictors. I'll send you a copy :)

Hey Cameron, as it is a descriptive and not a meta-analytical review, we did not assess the measurement quality of collective action - that would be an interesting research question for the future!

📣 Implications for the field:
• SIMCA is a solid starting model for environmental/climate action but needs adapting and expanding
• Rather than asking which are the most relevant predictors, we need to understand the contextual boundary conditions that determine when each predictors become relevant

• In less politicized contexts, environmental self-identity may replace social identification, and guilt may replace anger
• Social norms need to be considered to fully comprehend environmental collective action

• Social norms need to be considered to fully comprehend environmental collective action
• Social norms need to be considered to fully comprehend environmental collective action
• Social identification with a politicized group/ movement was the most robust predictor of environmental collective action
• Anger seems more relevant in (protest) contexts where injustice is focal
• Participative efficacy (an individuals' efficacy as part of a group) outshone collective efficacy
• Anger seems more relevant in (protest) contexts where injustice is focal
• Participative efficacy (an individuals' efficacy as part of a group) outshone collective efficacy

We dive deep into the psychology behind collective action - how people build a sense of identification with climate groups and come to believe that their collective efforts really can make a difference. It's about anger, activist burnout, protest perception and theories of socio-ecological change.

The book tackles two key questions: how can individuals be motivated to participate in collective climate action, and how can climate groups become resilient and effective?

👨🦰💰 We consistently observed that men and people with a higher income are more aware of and willing to join a Community Energy Initiative.
💪👥 This can partly be explained by perceived efficacy to join and contact with already involved members, BUT NOT with pro-environmental motivation.
