Predicting voting behavior with implicit attitude measures: the 2002 German parliamentary election

Area of Science:

• Social Psychology
• Political Psychology
• Attitude Measurement

Background:

• Implicit attitude measures are often assumed to predict only spontaneous actions.
• Emerging evidence suggests implicit measures can also enhance predictions of deliberate behaviors.
• Understanding the predictive validity of implicit measures for complex decisions like voting is crucial.

Purpose of the Study:

• To investigate if Implicit Association Test (IAT) measures of political attitudes improve voting behavior prediction beyond explicit self-reports.
• To examine the moderating role of general interest in politics on the relationship between explicit and implicit political attitudes.
• To assess the utility of implicit measures in predicting deliberate political choices.

Main Methods:

• A prospective study design was employed.
• Implicit political attitudes were measured using the Implicit Association Test (IAT) for major German political parties.
• Explicit political attitudes were assessed via self-report measures.
• Voting behavior in the 2002 German parliamentary elections served as the outcome variable.
• General interest in politics was measured to test for moderation effects.

Main Results:

• IAT measures significantly improved the prediction of voting behavior, adding predictive power beyond explicit self-report measures.
• General interest in politics was found to moderate the relationship between explicit and implicit political attitudes.
• The findings support the hypothesis that implicit attitudes contribute to predicting deliberate voting decisions.

Conclusions:

• Implicit attitude measures, specifically the IAT, offer valuable predictive utility for deliberate behaviors such as voting.
• The predictive power of implicit and explicit attitudes is influenced by individual differences in political interest.
• These findings have implications for developing more comprehensive models of attitude-behavior relationships in political contexts.
