Three studies assessed the relationship between need for closure (NFC) and evaluations of political ideology conversions as a function of mortality salience (MS). Following an experimental (vs control) manipulation, 156 participants evaluated politicians who switched political ideologies. Results indicate that MS induced people high in NFC to express greater support for politicians seeking consensus in the political centre, an effect consistent with research linking NFC to desires for group centrism and collective closure. A second study (N = 170) further clarified this issue by having participants evaluate political parties moving from their traditional left/right positions to the political centre. Participants high in NFC, when exposed to MS, expressed significantly higher levels of support for parties moving from the right to the centre. A third study (N = 276) explored how activating specific needs for consensus via MS increased support for a centrist political party described as uniform in thought and enjoying an internal (vs split) mandate. Results further indicate that mortality reminders amplify demands for consensus and clarity more than a demand for ideological clarity.
