Registered report protocol: Stress testing predictive models of ideological prejudice.

Area of Science:

• Social Psychology
• Political Psychology

Background:

• The association between ideology and prejudice varies across groups.
• Existing models predict this association using group ideology, status, and choice.
• Previous findings indicate perceived ideology is a parsimonious predictor.

Purpose of the Study:

• To stress-test existing models of the ideology-prejudice association.
• To evaluate model predictive utility with new prejudice measures and target groups.
• To develop and test new models using comparative prejudice operationalizations and the Implicit Association Test.

Main Methods:

• Study 1: Replicate previous models using an absolute measure of prejudice.
• Study 2: Develop new models for comparative prejudice using explicit and Implicit Association Test (IAT) measures.
• Utilize data from the Ideology 2.0 project (Project Implicit).

Main Results:

• Previous analyses showed perceived ideology models were more accurate and parsimonious.
• This study aims to validate these findings with distinct prejudice measures and additional groups.
• Study 2 will establish new models for comparative prejudice, incorporating IAT data.

Conclusions:

• Perceived ideology appears to be a robust predictor of the ideology-prejudice association.
• Further research is needed to confirm model generalizability across diverse groups and prejudice measures.
• The findings will refine our understanding of intergroup relations and political attitudes.
