"Groupthink is a deterioration of mental efficiency, reality testing, and moral judgment that results from in-group pressures."

Group Influence
People change their behavior or attitudes to match those of the group they identify with or seek to belong to. Group members often prematurely seek consensus, influencing decisions and actions.
Group Polarization
The original attitudes of individuals become exaggerated when shared by others. Group members can fuel each other’s sense of superiority, dislike for adversaries and outrage at any perceived threat. In extreme cases, this exaggerated polarization can lead to group frenzy and mob behavior.
In-Group Bias
Identification with a group makes individuals unduly subject to being influenced by the biases, loyalties, and values of the group. Embedding reporters with troops during a war builds ties of loyalty and identification that make it almost impossible for them to report in an impartial or comprehensive way.
