We analyze in this article the effects of personality on attitudes toward foreign policy through a comprehensive aspect-level approach. We claim that previous observed null domain-level effects are the product of the aspect-level effects of opposing signs. By and large, we show that some personality effects are of comparable size or bigger than demographics studied in the literature, and that some of these effects are unique and independent of demographic covariates. Our results show that openness, orderliness, and compassion render people to be more supportive of cooperation. Assertiveness is the primary driver of support for the use of military force, whereas politeness and withdrawal ground reverse effects. Volatility roots isolationism postures, whereas industriousness, enthusiasm, and compassion show strong opposing effects. Moving beyond the Big Five personality domain approach provides us with a deeper and more nuanced understanding of how personality is associated with attitudes toward international issues.
