| Whereas a large literature traditionally focuses on predicting collective action to achieve social change (e.g., strikes, demonstrations, petitions), we propose the very first experimental research on its potential psychological consequences. This is important because this research has the unique potential to discover how undertaking collective action activates psychological processes that increase the likelihood of social change (e.g., emancipation, equalization). Moving beyond existing models, three sets of studies unravel how “action changes actors” through a novel and integrative focus on empowerment and politicization. A better understanding of these psychological processes greatly improves our ability to predict, explain, and achieve social change. |
