“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.”
