Irving L. Janis
Irving L. Janis was a renowned research psychologist who made significant contributions to the field of social psychology.
He is best known for developing the theory of "groupthink," which explains how groups can make poor decisions due to pressure for conformity.
Janis spent much of his career at Yale University and later became a professor emeritus at the University of California, Berkeley.
His work on groupthink has had a lasting impact on understanding collective decision-making processes.
Additionally, Janis collaborated with Carl Hovland on studies of attitude change, including the sleeper effect.
He retired in 1986, leaving behind a legacy of influential research in group dynamics and social psychology.
