π What is Confirmation Bias?
Confirmation bias is the tendency to favor information that confirms existing beliefs or biases. This can involve selectively seeking out, interpreting, and remembering information that validates one's own perspectives, while disregarding or downplaying contradictory evidence. It's a common cognitive bias that affects everyone to some degree.
π History and Background
The term 'confirmation bias' was coined by English psychologist Peter Wason in the 1960s. Wason conducted experiments demonstrating that people tend to seek information that confirms their hypotheses, even when disconfirming evidence is available. This bias has roots in the way our brains process information, prioritizing efficiency and consistency.
