The Department of Criminology at the Max Planck Institute for the Study of Crime, Security and Law in Freiburg im Breisgau, Germany, is recruiting for a fully funded PhD position focused on 'Short-Term Mindsets and Crime: From Theory to Intervention.' This opportunity is ideal for candidates interested in experimental and interdisciplinary research on crime, decision-making, and behavioral science. The research program investigates the role of short-term mindsets in criminal behavior, exploring their causes, dynamics, and potential for intervention. The position offers scope for developing independent research ideas within the framework of short-term mindsets theory, including situational triggers, decision-making processes, behavioral proxies, and interventions. Applicants should hold or be close to completing a master's degree in psychology, pedagogy, empirical criminology, behavioral economics, sociology, or a related field. Experience with advanced research methods such as experimental designs, longitudinal data, or ecological momentary assessment is an asset but not required. Strong interest in crime research, teamwork, excellent English language skills, and commitment to open science are essential. German language skills are helpful but not mandatory. The Max Planck Institute for the Study of Crime, Security and Law is a leading European center for criminology, public security, and criminal law research.
