A Comprehensive Aspect-Level Approach to the Personality Micro-Foundations of Foreign Policy Attitudes

Area of Science:

• Political Science
• Social Psychology

Background:

• Previous research often found null effects when examining broad personality domains and foreign policy attitudes.
• This study posits that null findings result from opposing effects at a more granular, aspect level.

Purpose of the Study:

• To investigate the nuanced relationship between specific personality traits and foreign policy attitudes.
• To demonstrate the utility of an aspect-level approach over a domain-level approach in understanding these associations.

Main Methods:

• Analysis of foreign policy attitudes using a comprehensive aspect-level approach.
• Examination of personality traits beyond the traditional Big Five domain level.

Main Results:

• Specific personality traits, such as openness, orderliness, and compassion, positively correlate with support for cooperation.
• Assertiveness strongly predicts support for military force, while politeness and withdrawal show inverse relationships.
• Volatility is linked to isolationist stances, contrasted by industriousness, enthusiasm, and compassion.

Conclusions:

• An aspect-level analysis reveals significant and unique effects of personality on foreign policy attitudes, often stronger than demographic factors.
• Moving beyond broad personality domains provides a deeper, more detailed understanding of individual differences in international issue attitudes.
