Quiet: The Power of Introverts in a World That Can't Stop Talking

by Susan Cain

Introverts, in contrast, may have strong social skills and enjoy parties and business meetings, but after a while wish they were home in their pajamas. They prefer to devote their social energies to close friends, colleagues, and family. They listen more than they talk, think before they speak, and often feel as if they express themselves better in writing than in conversation. They tend to dislike conflict. Many have a horror of small talk, but enjoy deep discussions.

As Jung felicitously put it, “There is no such thing as a pure extrovert or a pure introvert. Such a man would be in the lunatic asylum.”

introverts prefer to work independently, and solitude can be a catalyst to innovation.

Since then, some forty years of research has reached the same startling conclusion. Studies have shown that performance gets worse as group size increases: groups of nine generate fewer and poorer ideas compared to groups of six, which do worse than groups of four. The “evidence from science suggests that business people must be insane to use brainstorming groups,” writes the organizational psychologist Adrian Furnham.

The one exception to this is online brainstorming. Groups brainstorming electronically, when properly managed, not only do better than individuals, research shows; the larger the group, the better it performs.

“Restorative niche” is Professor Little’s term for the place you go when you want to return to your true self.

If you’re a manager, remember that one third to one half of your workforce is probably introverted, whether they appear that way or not. Think twice about how you design your organization’s office space. Don’t expect introverts to get jazzed up about open office plans or, for that matter, lunchtime birthday parties or team-building retreats. Make the most of introverts’ strengths—these are the people who can help you think deeply, strategize, solve complex problems, and spot canaries in your coal mine.

Also, remember the dangers of the New Groupthink. If it’s creativity you’re after, ask your employees to solve problems alone before sharing their ideas. If you want the wisdom of the crowd, gather it electronically, or in writing, and make sure people can’t see each other’s ideas until everyone’s had a chance to contribute.
