This fully funded PhD position at Erasmus University Rotterdam offers a unique opportunity to investigate the social effects of democratic decision-making within citizen collectives. Hosted by the Erasmus School of Social and Behavioural Sciences (ESSB) and linked to the Erasmus School of Philosophy, the project is part of the ECCO consortium and the Governance & Pluralism team, providing a vibrant academic environment and peer cohort. The four-year research project aims to understand whether citizen collectives act as 'schools for democracy' by exploring how participatory decision-making influences civic engagement and pro-social behavior beyond the collective. The study will compare different types of citizen collectives, including cooperatives and co-housing eco-villages, focusing on both labor market and non-work settings. A key output will be the development of a psychological assessment tool—a serious game—to measure civic engagement and cooperative tendencies, embedding data collection within gameplay. As the PhD researcher, you will conduct comparative research, design and implement the serious game, analyze spillover effects of collective participation, collaborate with networks such as LaNSCO, and publish both academic and practitioner-oriented outputs. The position emphasizes transdisciplinary research, close collaboration with citizen collectives, and the development of creative methodologies that engage practitioners. Applicants should have a Master’s degree in a relevant field (social/cultural anthropology, public administration, psychology, sociology, political science, or transition studies), strong interest in democratic innovation and behavioral sciences, and experience with qualitative research methods. Proficiency in Dutch and English is required, along with the ability to work independently and in teams. Experience with ethnographic or participatory action research and comfort working in communities are advantageous. The employment package includes a competitive salary (€3,059 - €3,881 gross per month for full-time), 41 days paid leave, holiday and end-of-year bonuses, pension contributions, and support for relocation (including the 30%-ruling for eligible candidates). Additional benefits cover work-life balance, personal development, and access to university facilities. The position starts on 1 September 2026, with an initial one-year contract and extension for three more years upon proven suitability. Applications should be submitted online with a motivation letter and CV before 15 February 2026. The selection process involves one or two interviews, expected in mid/end-February.
