What does confirmation bias refer to in decision-making?

Confirmation bias refers to the tendency to favor, search for, interpret, and remember information in a way that confirms one's preexisting beliefs or hypotheses. When individuals make decisions, they are more likely to seek out information that supports what they already believe, while neglecting or undervaluing evidence that contradicts those beliefs.

This bias can lead decision-makers to reinforce their existing views and decisions despite contrary evidence. By emphasizing information that aligns with their beliefs, individuals may ignore pertinent data that could lead to a more balanced and informed decision. Thus, confirmation bias can significantly influence behavior and decision-making processes in various contexts, including personal, professional, and academic settings.
