In this paper, we discuss the question of why only a few men decide to study social science courses such as social work. While the conceptual base of our analysis includes the theory of planned behaviour (TPB) and theories centring on gender role orientations, the empirical base is a random cluster sample of high school graduates in Switzerland. Results show different gender effects, as well as direct and indirect effects, for all the TPB factors. Gender role orientations and the question of how a social science profession fits one's own gender identity appear to be of particular importance only among male students.
