“Susan Krauss Whitbourne, a professor of psychology at the University of Massachusetts-Amherst, recently made the case for introverts in an article in Psychology Today. To her, introverts make for better leaders for a simple reason: “They’re more likely to listen and pay attention to what other people are saying.”
This article also mentions a book:” Quiet: The Power of Introverts in a World That Can’t Stop Talking”. I haven’t read this book yet but it must be an interesting one.
