"An unprecedented history of the personality test that has achieved cult-like devotion, devised a century ago by a pair of homemakers and found today in boardrooms, classrooms, and beyond. The Myers-Briggs Type Indicator is the most popular personality test in the world. It has been harnessed by Fortune 100 companies, universities, hospitals, churches, and the military. Its language--of extraversion vs. introversion, thinking vs. feeling--has inspired online dating platforms and Buzzfeed quizzes alike. And yet despite the test's widespread adoption, experts in the field of psychometric testing, a $500 million industry, struggle to account for its success--no less to validate its results. How did the Myers-Briggs test insinuate itself into our jobs, our relationships, our Internet, our lives? First conceived in the 1920s by the mother-daughter team of Katherine Briggs and Isabel Briggs Myers, a pair of aspiring novelists and devoted homemakers, the Myers-Briggs was designed to bring the gospel of Carl Jung to the masses. But it would take on a life of its own, reaching from the smoke-filled boardrooms of mid-century New York to Berkeley, California, where it was honed against some of the twentieth century's greatest creative minds. It would travel across the world to London, Zurich, Cape Town, Melbourne, and Tokyo; to elementary schools, nunneries, wellness retreats, and the closed-door corporate training sessions of today. Drawing from original reporting and never-before-published documents, The Personality Brokers examines nothing less than the definition of the self--our attempts to grasp, categorize, and quantify our personalities. Surprising and absorbing, the book, like the test at its heart, considers the timeless question: What makes you you"-- Provided by publisher.
