Cognitive bias

Subject areaCommunication sciences

Cognitive bias: Cognitive biases are systematic distortions of judgement: mental shortcuts that lead to predictably wrong conclusions.

Amos Tversky and Daniel Kahneman described them in the article "Judgment under Uncertainty: Heuristics and Biases" (Science, 1974). Confirmation bias, availability bias, anchoring and the bandwagon effect are examples. In a company they turn a clue into false proof.

An example

A sales director judges a market by the last two customers met, and overlooks the data of the whole year.
