This chapter critiques the Myers-Briggs Personality Test, exploring its reliance on self-reported data and the contradictions inherent in personality traits. It contrasts the test with the scientifically validated Big Five model and discusses the origins of Myers-Briggs, tracing back to Catherine Cook Briggs and Carl Jung's theories. Through humor and personal anecdotes, the chapter examines the oversimplification of complex human behaviors and the appeal of personality assessments.
