Understanding individual and collective response to climate change: The role of a self-other mismatch.

Several scientists have shown the importance of mitigating global warming and have highlighted a need for major social change, particularly when it comes to meat consumption and collective engagement. In the present study ( = 486), we conducted a cross-sectional study to test the mismatch model, which aims at explaining what motivates individuals to participate in normative change. This model stipulates that perceiving a self-other difference in pro-environmental attitudes is the starting point and can motivate people to have high pro-environmental intentions.
