Irving Janis

Irving Janis was a prominent American psychologist who made significant contributions to the field of psychology. Born in 1918, Janis spent his career studying group dynamics and decision-making processes.

Janis held esteemed positions at prestigious institutions, including Yale University and the University of California, Berkeley, where he was a professor emeritus. His work had a lasting impact on the field of psychology, and his influence can be measured by his citation ranking.

Janis passed away in 1990, leaving behind a legacy of important work in the field of psychology.
