 Similarly, a police detective may identify a suspect early in an investigation, but then may only seek confirming rather than disconfirming evidence.Confirmation bias, coined by English psychologist Peter Wason, is the tendency of people to favor information that confirms or strengthens their beliefs or values, and is difficult to dislodge once affirmed.Confirmation bias is an example of a cognitive bias, and also of the tendency to mistakenly perceive connections and meaning between unrelated things, termed apophenia.
