Cook: Tell me more about these “pitfalls of groupwork.”

Cain: When you’re working in a group, it’s hard to know what you truly think. We’re such social animals that we instinctively mimic others’ opinions, often without realizing we’re doing it. And when we do disagree consciously, we pay a psychic price. The Emory University neuroscientist Gregory Berns found that people who dissent from group wisdom show heightened activation in the amygdala, a small organ in the brain associated with the sting of social rejection. Berns calls this the “pain of independence.”

Take the example of brainstorming sessions, which have been wildly popular in corporate America since the 1950s, when they were pioneered by a charismatic ad executive named Alex Osborn. Forty years of research shows that brainstorming in groups is a terrible way to produce creative ideas. The organizational psychologist Adrian Furnham puts it pretty bluntly: The “evidence from science suggests that business people must be insane to use brainstorming groups. If you have talented and motivated people, they should be encouraged to work alone when creativity or efficiency is the highest priority.”

This is not to say that we should abolish groupwork. But we should use it a lot more judiciously than we do today.

Cook: What are some of the other misconceptions about introverts and extroverts?

Cain: One big one is the notion that introverts can’t be good leaders. According to groundbreaking new research by Adam Grant, a management professor at Wharton, introverted leaders sometimes deliver better outcomes than extroverts do. Introverts are more likely to let talented employees run with their ideas, rather than trying to put their own stamp on things. And they tend to be motivated not by ego or a desire for the spotlight, but by dedication to their larger goal. The ranks of transformative leaders in history illustrate this: Gandhi, Eleanor Roosevelt, and Rosa Parks were all introverts, and so are many of today’s business leaders, from Douglas Conant of Campbell Soup to Larry Page at Google.

Cook: Is there any relationship between introversion and creativity?

Cain: Yes. An interesting line of research by the psychologists Mihaly Csikszentmihalyi and Gregory Feist suggests that the most creative people in many fields are usually introverts. This is probably because introverts are comfortable spending time alone, and solitude is a crucial (and underrated) ingredient for creativity.
