Irving Lester Janis (May 26, 1918 – November 15, 1990) was an American research psychologist at Yale University and a professor emeritus at the University of California, Berkeley most famous for his theory of "groupthink", which described the systematic errors made by groups when making collective decisions.[1][2] A Review of General Psychology survey, published in 2002, ranked Janis as the 79th most cited psychologist of the 20th century.[3]
