Daryl Bem

Daryl J. Bem (born June 10, 1938) is a social psychologist and professor emeritus at Cornell University. He is the originator of the self-perception theory of attitude formation and change. He has also researched psi phenomena, group decision making, handwriting analysis, sexual orientation, and personality theory and assessment.

Bem received a BA in physics from Reed College in Portland, Oregon in 1960 and began graduate work in physics at the Massachusetts Institute of Technology. The civil rights movement had just begun, and he became so intrigued with the changing attitudes toward desegregation in the American South that he decided to switch fields and pursue a career as a social psychologist specializing in attitudes and public opinion. He obtained his PhD in social psychology from the University of Michigan in 1964.

Bem taught at Carnegie-Mellon University, Stanford, Harvard, and Cornell University. He started at Cornell in 1978 and retired in 2007, becoming a professor emeritus.

He testified before a subcommittee of the United States Senate on the psychological effects of police interrogation and served as an expert witness in court cases involving sex discrimination.
