How to motivate people to take part in collective action and when and what type of action works best

About Eran Halperin

​I'm currently a full professor of psychology at the Hebrew University of Jerusalem.

My research uses psychological and political theories and methods to investigate different aspects of inter-group conflicts. More specifically, I am interested in widening the understanding regarding the psychological roots of some of the most destructive political ramifications of inter-group relations – e.g., intolerance, exclusion and inter-group violence and conflict.


​In order to apply our research findings, and lead to real change in the world, we established the aChord Center.
