Differences in sensitivity to deviance partly explain ideological divides in social policy support.

Area of Science:

• Social Psychology
• Political Psychology
• Cognitive Science

Background:

• Political ideology shapes social policy preferences.
• Existing research highlights affective and motivational factors in political differences.

Purpose of the Study:

• To investigate if cognitive sensitivity to deviance underlies political differences in social policy support.
• To explore the role of cognitive deviance detection in mediating political ideology and policy preferences.

Main Methods:

• Three studies were conducted using geometric shape perception tasks.
• Participants rated their differentiation between perfect and imperfect shapes.
• Political ideology was assessed and correlated with policy support measures.

Main Results:

• Conservative participants demonstrated greater sensitivity to shape deviance compared to liberal participants.
• Shape differentiation mediated the relationship between political ideology and support for punishment, public aid, and policies for marginalized groups.
• The effect was specific to policies targeting moderately deviant groups.

Conclusions:

• Conservatives' heightened cognitive propensity to distinguish deviance contributes to political differences in social policy.
• Cognitive factors, beyond affective responses, play a significant role in shaping political attitudes towards social policies.
• Understanding cognitive biases in deviance detection offers new insights into political polarization.
