A psychologist challenges the tyranny of optimism by claiming that negative thinking is often a far better way to deal with anxiety than striving to stay positive . How often are we urged to "look on the bright side"? From Norman Vincent Peale to the ubiquitous smiley face, optimism has become an essential part of American society. In this long-overdue book, psychologist Julie Norem offers convincing evidence that, for many people, positive thinking is an ineffective strategy--and often an obstacle--for successfully coping with the anxieties and pressures of modern life. Drawing on her own research and many vivid case histories, Norem provides evidence of the powerful benefits of "defensive pessimism," which has helped millions to manage anxiety and perform their best work.
