The Personality Brokers

July 9, 2018
Emre (Paraliteracy), an associate English professor at Oxford University, tells the fascinating story of the origins of the world’s most widely used personality test, the Myers-Briggs Personality Inventory (MBPI.) The MBPI, which was introduced in 1943, classifies personality in terms of four polarities: introversion-extraversion, intuition-sensing, feeling-thinking, and judging-perceiving. Emre profiles each of its developers, Katharine Cook Briggs and her daughter, Isabel Briggs Myers, noting neither possessed any formal psychological training. She also observes that for Briggs, personality “typing” was a kind of “personal religion” inspired by her near-reverential regard for Carl Jung’s theories, while for Myers, who developed the MBPI’s first 117-question multiple choice test, it was more of a vocation and, later, a business. In a major omission, Emre never discusses, or even delineates, the 16 personality types derived from the MBPI. However, she is excellent at recounting how the MBPI began to sweep American institutions in the 1950s–Brown University administered it to all 950 members of the class of 1958—and attained widespread popularity after its creators’ deaths. Emre’s fine study balances some sharp criticisms, such as from social theorist Theodor Adorno, with her own candid testimonial to the MBPI’s effectiveness; in the process she restores Briggs and Myers to their rightful place in the annals of popular psychology.
