Confirmation bias is the psychological tendency to look for, interpret, favor, and recall info in a way that confirms or supports your preexisting beliefs. This cognitive bias acts as a mental shortcut, causing individuals to unconsciously filter out data that contradicts their current views. Coined by psychologist Peter Wason in the 1960s, it functions as a way for the brain to process massive amounts of information efficiently, though it often leads to flawed reasoning and overconfidence.
