formaltechnical

The tendency to search for, interpret, favor, and recall information in a way that confirms one's pre-existing beliefs or hypotheses.

This is a specific type of cognitive bias where individuals are not just biased, but actively seek out and give more weight to evidence that supports what they already believe, while downplaying or ignoring contradictory evidence.

The story behind the word. The term 'confirmation bias' combines 'confirmation' (from Latin 'confirmare,' meaning 'to make firm, establish') and 'bias' (from Old French 'biais,' meaning 'slant'). While the underlying psychological phenomenon has been observed for centuries, the specific term 'confirmation bias' was coined by English psychologist Peter Wason in the 1960s. It precisely describes the human tendency to seek out and interpret information in a way that solidifies one's pre-existing beliefs.
