Psychologist Julie K. Norem joined the faculty at Wellesley College in 1992, and she teaches courses in personality psychology, research methods, as well as a seminar on optimism and pessimism. Her research focuses on the strategies people use to pursue their goals, with an emphasis on the strategy of defensive pessimism; and on the ways self-knowledge influences adaptation, performance, and social relationships, particularly among those who feel like impostors. Julie is also the author of the book, "The Positive Power of Negative Thinking."
