Pauline Grippa holds a PhD in social psychology from the Université libre de Bruxelles (Center for Social and Cultural Psychology). Her thesis, combining field studies and experiments, explores conflicts within social movements, with a particular focus on the dynamics of competition between sub-movements within the global struggle. She is currently a researcher at the Center for the Study of Political Life (CEVIPOL) as part of the “NotLikeUs” project funded by the FNRS-FWO. After analyzing internal conflicts within social movements, her research now focuses on emotional polarization between citizens and dissatisfaction with politics, seeking to identify factors that can reduce this polarization and its harmful effects on democratic processes.
