The studies of groupthink and groupthink antecedents reveal a mixed body of results.

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.
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.
The study's results also showed that groupthink occurs less in computer-mediated discussions than when people are face to face. Moreover, computer-mediated discussions often fail to result in a group consensus, or lead to less satisfaction with the consensus that was reached, compared to groups operating in a natural environment.
Studies have shown that cohesion can cause performance and that performance can cause cohesion. [29] [30] Most meta-analyses (studies that have summarized the results of many studies) have shown that there is a relationship between cohesion and performance.

This portrayal of the Asch studies was suggested to fit with social psychology narratives of situationism, obedience and conformity, to the neglect of recognition of disobedience of immoral commands (e.g., disobedience shown by participants in Milgram Studies), desire for fair treatment (e.g., resistance to tyranny shown by many participants in ...
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.
