Cognitive Bias
A systematic deviation from rational judgment caused by mental shortcuts (heuristics).
Definition
Common biases: confirmation (seeking evidence that confirms existing beliefs), anchoring (over-relying on first information), availability (judging probability by ease of recall), sunk cost (continuing because of past investment), Dunning-Kruger (incompetence prevents recognizing incompetence). Biases cannot be eliminated — only flagged and counteracted.
