Confirmation bias is a psychological phenomenon that refers to the tendency of individuals to search for, interpret, and remember information in a way that confirms their preexisting beliefs or hypotheses. This bias can lead to individuals ignoring or dismissing evidence that contradicts their beliefs, and can contribute to the perpetuation of false beliefs or misconceptions. Confirmation bias can have significant implications in various aspects of life, including personal decision-making, scientific research, and public discourse. Researchers study confirmation bias to better understand how it influences human cognition and behavior, and to identify strategies to mitigate its effects.
