Employing public resources for promoting entrepreneurships demands careful selection of candidates who are most promising to set up a successful entrepreneurial career. This study addresses the relation between an individuals’ entrepreneurial potential, identified through personality traits, and aspects of human and social capital, based on prior entrepreneurial exposure. A psychometric test, called F-DUP^N, measures the strengths of personality traits considered relevant for successful entrepreneurial activity. To test our hypotheses, we collected data of 166 individuals. All of them are university students or graduates and have indicated a specific interest in entrepreneurial activity. A major result is that participants experienced in self-employment, with self-employed parents and with self-employed friends show a higher entrepreneurial potential than participants who do not have these experiences or relations. Furthermore, we find in line with other studies that differences in entrepreneurial potential become less pronounced with increasing age. An interpretation is that personality traits significant for entrepreneurial activity are not stable over time and can also be acquired at a later stage in life.
