Decision Behaviour- Improving Expert Judgement

Abstract

People’s judgements are not perfect. Even experts make mistakes. Interestingly, mistakes in judgement and decision-making are not random. Professionals deviate systematically from normative standards. Per definition, systematic biases result in reduced decision quality, and accordingly, may have serious consequences. However, the fact that judgement biases are systematic also gives hope. If the biases and their causes can be identified, it should be possible to correct them.
