Susan Cain is a former corporate lawyer and negotiations consultant. Also, she descibers herself as an introvert.
Cain notes that at least one-third of the all people we know are introverts in her book Quiet: The Power of Introverts in a World That Can’t Stop Talking. Although they are undervalued by our culture, introverts have made some of the great contributions to society. Some examples which support this theory are Chopin’s nocturnes to the invention of the personal computer and Gandhi’s transformative leadership.
Susan states that our workplaces, schools, and religious institutions for extroverts, and that this bias creates a waste of energy, talent, and happiness. She also explains why introverts are capable of great love and great achievement, not in spite of their temperaments but because of them. All of her stances are based on intensive research in psychology and neurobiology and on prolific interviews.
