  • Title: Purity, politics, and polarization: Political ideology moderates threat-induced shifts in moral purity beliefs.
    Author: Leota J, Simpson D, Mazidi D, Nash K.
    Journal: Br J Soc Psychol; 2023 Apr; 62(2):806-824. PubMed ID: 36344880.
    Abstract:
    There is considerable research showing that economic threat influences people's social and political views. There are two prevailing perspectives on threat and political attitudes, broadly defined as the Conservative Shift Hypothesis and the Entrenching Hypothesis. The former predicts that threat induces change in the conservative direction (for both conservatives and liberals), whereas the latter predicts that threat causes people to adhere more strongly to their prexisting political perspective. In two experimental studies (one pre-registered replication), we find evidence in support of the Entrenching Hypothesis. Conservatives responded to Economic Threat with increased endorsement of the conservative moral foundation Purity, whereas liberals responded to Economic Threat with decreased endorsement of the Purity foundation. Economic Threat appears to increase commitment to one's pre-existing political ideology and not conservatism specifically. Implications for psychological theory and future directions are discussed.
