In the new issue of British Journal of Political Science, you will find an article by me. Here is the abstract:
In order to explain differences in political interest, two strands of literature point to the relevance of either dispositional or situational factors. I remedy this and show how political interest is shaped by the interplay between personality differences and the political environment. Specifically, I demonstrate that people with a stable motivation for engaging with new ideas are more interested in politics when exposed to new political events, e.g. during election campaigns and when unexpected events unfold. The results have implications for our understanding of political inequalities in democratic engagement and shed light on how citizens’ interest in politics can be relatively stable over time as well as responsive to the political environment in predictable ways.
