All Social Biases and Group Effects

Groups the phenomena whose central finding concerns how the presence, expectation or judgment of other people shapes an individual's behavior or how one person explains another person's behavior. Belongs here: the Bystander Effect, the False Consensus Effect, the Fundamental Attribution Error, Groupthink, the Halo Effect, the Pygmalion Effect, Self-Serving Bias and Social Loafing, each documented in a social or group setting rather than in private judgment alone. A phenomenon whose distortion concerns a single person's own private estimate or memory, with no other person's presence or judgment involved, is filed under decision-making and judgment biases or memory biases and effects instead.
