Which bias is defined as noticing only information that supports existing beliefs?

Belief perseverance is a cognitive bias where individuals continue to hold onto their beliefs even when confronted with evidence that contradicts those beliefs. This bias leads individuals to selectively gather or focus on information that confirms their pre-existing views, thereby reinforcing their beliefs rather than challenging them. In this way, belief perseverance can inhibit objective decision-making and critical thinking, as it limits exposure to diverse perspectives and contradictory information. As a result, one may overlook or dismiss credible evidence, solidifying their original stance despite new insights.

In the context of the other biases, hindsight bias reflects the tendency to see events as having been predictable after they have already happened, conservatism bias involves the reluctance to change one's beliefs in response to new evidence, but it does not specifically pertain to seeking out confirming information. The illusion of control refers to the belief that one can influence events that are beyond their control. While each of these biases plays a role in how individuals process information and make decisions, belief perseverance specifically highlights the issue of only acknowledging information that aligns with pre-existing beliefs.
