Group politics – where politicians discuss certain groups in society and their supposed positive or negative contributions to it – can promote or damage confidence and engagement in the democratic process. In general we have expected that political statements about groups affect different group members in similar ways. Yet psychological research has pointed to several differences between men and women that suggest that the two sexes may react differently to such statements about groups they belong to — such as their levels of 'competitive worldview', the extent to which they define themselves in terms of their group identities, and their stress responses. The project uses four survey and lab experiments among to different groups (Muslims and schoolteachers in Denmark) to investigate whether group messages in politics actually affect men and women’s political trust differently; and if so, whether the proposed characteristics can help us to understand why.
