Quiet: The Power of Introverts in a World that Can’t Stop Talking by Susan Cain is a fascinating look at introversion and what having that personality type actually means. Cain is very effective at taking a lot of disparate psychological research and forming it into a cogent picture of introversion and how introverts relate to the world around them. Cain uses illustrative examples from scientific research, case studies and extensive interviews she performed during the course of her research for this book.
Between one third and one half of the population are introverts, so this book has the potential to be very useful to people with personalities on opposite ends of the introvert-extrovert spectrum relate to each other in work situations and in personal relationships. Cain presents many tips for introverts trying to function in a world that values extroversion, as well as tips for everyone to try to work against the psychological inclination to listen to those who are good presenters (even if the idea they are presenting isn’t very good).
