Decision-Making and Judgment Biases

Groups the phenomena of the psychology atlas whose central finding concerns a systematic distortion in how a person judges evidence, estimates a probability or weighs a choice. Belongs here: the Anchoring Effect, the Availability Heuristic, Confirmation Bias, the Dunning-Kruger Effect, Inattentional Blindness, the Mere Exposure Effect, the Placebo Effect and the Sunk Cost Fallacy, each a documented distortion of an individual's own judgment or expectation. A phenomenon whose distortion is chiefly about how a person perceives or explains another person, rather than about the person's own private judgment, is filed under social biases and group effects instead.
