Political change as group-based control: Threat to personal control reduces the support for traditional political parties.

People desire agentic representations of their personal and collective selves, such as their own nation. When national agency is put into question, this should increase their inclination to restore it, particularly when they simultaneously lack perceptions of personal control. In this article, we test this hypothesis of group-based control in the context of political elections occurring during socio-economic crises. We propose that people who are reminded of low (vs. high) personal control will have an increased tendency to reject traditional political parties that stand for the maintenance of a non-agentic political system. We experimentally manipulated the salience of low vs. high personal control in five studies and measured participants' intentions to support traditional and new political parties. Across four of five studies, in line with the predictions, low personal control reduced support for the main traditional conservative party (e.g., Partido Popular (PP) in Spain, the Republicans in France). These results appeared in contexts of national economic and/or political crisis, and were most pronounced when low (vs. high) national agency was made salient in Studies 4 and 5. The findings support the notion that rejecting the stability of the national political system can serve as a means to maintain a sense of control through the collective self.
