Tune into our latest episode as we dig into the Myers-Briggs Type Indicator (MBTI), arguably the world's most popular psychology idea. Despite its immense popularity, used by millions globally, we uncover the significant theoretical flaws that exist beneath its surface. The MBTI, based on Carl Jung's theory, lacks agreement with known facts and data, suffers from internal contradictions, and lacks testability when evaluated against rigorous scientific criteria. We explore how its underlying assumptions, like the existence of "true types" and the nature of its dichotomies, are not empirically supported. Discover why, despite these criticisms, the MBTI continues to shape public perceptions of psychology.
