If you’re one of the 2 million people who take the Myers-Briggs Type Indicator every year, perhaps you thought Myers and Briggs are the two psychologists who designed the test. In reality, a mother-daughter team created the test essentially at their kitchen table. In this episode, we look at the unlikely origins of the Myers-Briggs, going all the way back to the late 1800s when Katharine Cook Briggs turned her living room into a “cosmic laboratory of baby training” and set out to raise the perfect child.

In this three-part series, we uncover the strange history of the most popular personality test in the world, and how two women revolutionized personality testing—for better or for worse.
