The studies of groupthink and groupthink antecedents reveal a mixed body of results. Some studies indicate group cohesion and leadership style to be powerfully predictive of groupthink, while other studies indicate the insignificance of these factors. Group homogeneity and group insulation are generally supported as factors predictive of ...
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.
Of course, while this is true, it is equally likely that the study of the social (group) behaviors of other animals might shed light on the evolutionary roots of social behavior in people. Territorial and dominance behaviors in humans are so universal and commonplace that they are simply taken for granted (though sometimes admired, as in home ...
The history of group dynamics (or group processes) [2] has a consistent, underlying premise: "the whole is greater than the sum of its parts." A social group is an entity that has qualities which cannot be understood just by studying the individuals that make up the group.
The concept of herd mentality has been studied and analyzed from different perspectives, including biology, psychology and sociology. This psychological phenomenon can have profound impacts on human behavior. Social psychologists study the related topics of collective intelligence, crowd wisdom, groupthink, and deindividuation.
There are three processes of attitude change as defined by Harvard psychologist Herbert Kelman in a 1958 paper published in the Journal of Conflict Resolution. [1] The purpose of defining these processes was to help determine the effects of social influence: for example, to separate public conformity (behavior) from private acceptance (personal belief).
Some studies have even shown that high-self-esteem groups showed more bias than did lower self-esteem groups. [11] This research may suggest that there is an alternative explanation and additional reasoning as to the relationship between self-esteem and in-group/out-group biases.
Further behavioral, economic, and social psychology research was done by Todd Rose to demonstrate the interchangeability of the terms pluralistic ignorance and collective illusions. His findings of historical events, scientific studies and social media patterns indicate that by using either term one is saying the same thing.
