The project HETEROBUTION offers a social psychological analysis of the link between social heterogeneity and redistribution. Drawing upon the social identity tradition and intergroup threat theories, we aim [a] to investigate how social heterogeneity shapes people’s redistribution preferences through triggering different identification patterns and associated perceptions of threat and [b] to reveal the moderating role of socioeconomic factors (socioeconomic status and economic inequality) and ideological factors (diversity beliefs and political orientation) in these processes. We aim to answer these questions using a wide array of methodological tools: Analyses of cross-national data, a large-scale national survey, novel social psychological experiments, and behavioral economic experiments.
This project is carried out within the framework of the National Recovery and Resilience Plan Greece 2.0, funded by the European Union – NextGenerationEU (Implementation body: HFRI)
The research project is hosted at the University of Crete (Department of Psychology)
