Loes Aaldering and Daphne Van Der Pas have published their paper on Gender Bias in Leader Stereotypes during Campaign and Routine Times in the British Journal of Political Science.

This article studies gender differences in media portrayals of political leadership, starting with the expectation that male politicians are evaluated more often on traits belonging to the male leader stereotype, and that female politicians have no such advantage. These gender differences are expected to be especially pronounced during non-campaign periods. To test these expectations, a large-scale automated content analysis of all Dutch national newspapers from September 2006 to September 2012 was conducted. The results show that male politicians received more media coverage on leadership traits in general, although the male and female leader stereotypes explain most of the variation in gender bias between leadership traits. These gender effects are found during seldom-studied routine periods but not during campaigns. As leadership trait coverage has electoral consequences, this gender-differentiated coverage likely contributes to the under-representation of women in politics.
