Susan Cain is an introvert in a world dominated by extroverts who insist that introverts should act like extroverts. She recently wrote a book titled, Quiet: The Power of Introverts in a World That Can't Stop Talking. I took special interest in Cain's talk because I am an off-the-charts introvert. The world constantly dominated by extroverts is a great loss, Cain asserts, because introverts, who avoid great amounts of stimulation, often "feel their most alive, their most switched on and their most capable when they are in quieter, more low key, environments. Unfortunately, our most important institutions (schools and work places) "are designed for extroverts, and extroverts' need for lots of stimulation." Society has a prejudice that creativity comes from gregarious gatherings. Schools and workplaces typically assemble students and workers into groups and ask them to work "together," even in activities such as writing. Kids that seek to work alone are seen as outliers and problems. Most teachers think of extroverts as superior students even though research shows that "introverts get better grades and are more knowledgeable." Introverts are often passed over for leadership positions, even though they tend to be careful and avoid unnecessary risks. Research shows that introverted leaders tend to let proactive workers run with their ideas, whereas extroverted leaders tend to interfere with the process (min 6:45). At min 8:00, Cain suggests that "ambiverts" probably have the best of both worlds.
