Confirmation Bias refers to a tendency for people to seek out and interpret information in ways that confirm their existing beliefs, while ignoring or dismissing any evidence that contradicts those beliefs. This can lead individuals to overestimate the accuracy of their own beliefs and underestimate the possibility that they might be wrong. Confirmation Bias is a common cognitive error that can impact decision-making and problem solving abilities, as well as interfere with open-minded exploration of new ideas or perspectives.
