Outline of Final Research Achievements

Dichotomous thinking is an individual's propensity to think in terms of binary opposition, such as “black or white,”“good or bad,” and “all or nothing.” Previous studies have shown that the dichotomous thinking links to undesirable psychological traits. The purpose of this study was to reveal the function of the dichotomous thinking by exploring the relationships between the thinking style and externalizing problem behaviors. Main findings were as follows: (1) The dichotomous thinking has a significant relationship with a grandiose entitlement. (2) There are significant positive correlations between the dichotomous thinking and the Dark Triad personality traits. (3) The dichotomous thinking traits tend to decline with age. (4) There is a positive correlation between the dichotomous thinking and aggression, and the dichotomous thinking and the aggression were more strongly correlated in younger participants.
