We don’t need giant personalities to transform companies. We need leaders who build not their own egos but the institutions they run. - Susan Cain

Americans prioritize happiness so much that we wrote the pursuit of it into our founding documents, then proceeded to write over thirty thousand books on the subject, as per a recent Amazon search. We’re taught from a very young age to scorn our own tears (“Crybaby!”), then to censure our sorrow for the rest of our lives. In a study of more than seventy thousand people, Harvard psychologist Dr. Susan David found that one-third of us judge ourselves for having “negative” emotions such as sadness and grief.

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. Face-to-face contact is important because it builds trust, but group dynamics contain unavoidable impediments to creative thinking. Arrange for people to interact one-on-one and in small, casual groups. Don’t mistake assertiveness or eloquence for good ideas. If you have a proactive work force (and I hope you do), remember that they may perform better under an introverted leader than under an extroverted or charismatic one.

...if you can think of meetings you've attended, you can probably recall a time - plenty of times - when the opinion of the most dynamic or talkative person prevailed to the detriment of all.
