This book summarizes findings from the first systematic study of "eccentrics": highly talented and unusual people who are somewhere between "normal" and "nuts". This is a domain occupied by genuine geniuses and charming crackpots whose common feature is that they refuse to hold commonly held beliefs or refuse to act in accordance with the norms of society. Although the book would have been a more compelling read if it treated each individual in more depth, and its conclusions more convincing if there were more tables of data, it is nonetheless a delightful book that will give you either more respect for the eccentric (if you believe that you are "normal") or greater confidence in yourself (if you suspect--or know--that you are eccentric). Recommended.
