Which cognitive bias is most associated with noticing and remembering evidence that supports what you already believe?

Confirmation bias is one of the best-known cognitive biases in psychology. It leads people to prefer information that fits their prior views while discounting contradictory evidence. This can affect memory, judgment, politics, science, and everyday decisions. The bias is not usually conscious; it often happens automatically as the brain tries to make sense of information efficiently. Recognizing confirmation bias is important for critical thinking and good decision-making.
