The Rise Of The Myers-Briggs, Chapter 3: What Is It Good For?

When Isabel Briggs Myers imagined that her homegrown personality test would change the world, she couldn’t have pictured this. Today, millions take the Myers-Briggs Type Indicator each year. Countless organizations use it, from General Motors to the CIA. But there’s one field that mostly rolls its eyes at the test: psychology. 

In our final chapter, Isabel rescues her indicator from the verge of extinction, but has to make some compromises. And we explore what the Myers Briggs does (and doesn’t) measure, and why people love it despite psychologists' complaints.

Listen to Chapter 1 and Chapter 2 of this series.
