In this riveting, far-reaching book [Emre] brings the skills of a detective, cultural critic, historian, scientist and biographer to bear on the MBTI and the two women who invented and promoted it.... She is never condescending to or dismissive of the people who find their four-dimensional profiles illuminating and helpful. That is why, when Ms. Emre describes her book as being 'for the skeptics, the true believers, and everyone in between,' she is absolutely right. -Wall Street Journal

Merve Emre's new book begins like a true-crime thriller, with the tantalizing suggestion that a number of unsettling revelations are in store.... It takes a while to realize that Emre has gotten you hooked under arguably false pretenses, but what she finally pulls off is so inventive and beguiling you can hardly begrudge her for it. The revelations she uncovers are less scandalous than they are affecting and occasionally (and delightfully) bizarre.... The Personality Brokers is history that reads like biography that reads like a novel-a fluid narrative that defies expectations and plays against type. -New York Times

Emre is careful to be generous to those who fit into this category [who believe in the MBTI], writing at the end of the book about the enthusiasts she encountered along the way. -The Outline

This is a sparkling biography-not just of a pair of remarkable women, but of a popular personality tool. Merve Emre deftly exposes the hidden origins of the MBTI and the seductive appeal and fatal flaws of personality types. Ultimately, she reveals that a sense of self is less something we discover, and more something we create and revise. -Adam Grant, New York Times bestselling author of Give and Take, Originals, and Option B with Sheryl Sandberg
