Episode 163: Personality
Released March 3rd, 2026
Can Buzzfeed quizzes, Myers-Briggs Types, and Enneagrams tell us anything valid about who we are? In episode 163 of Overthink, Ellie and David discuss personality. They talk through the Big Five personality test and its legitimacy, the history of the Myers-Briggs Type Indicator test (MBTI), and how the concept of personality emerged out of abnormal psychology. Why did the concept of personality replace using literature to understand the self? How does the concept of personality presuppose a fixed concept of the self? And what is the connection between MBTI and World War II? In the Substack bonus segment, your hosts think about how personality tests might be susceptible to the Barnum effect and their reduction of the self to egos.
