Belief perseverance refers to our tendency to cling onto our beliefs even in the face of contradicting evidence. This psychological phenomenon arises due to cognitive biases, such as confirmation bias and cognitive dissonance. Confirmation bias leads us to seek and interpret information that supports our existing beliefs, while cognitive dissonance pushes us to minimize inconsistencies between our beliefs and new information. We are motivated to maintain a consistent worldview and protect our self-identity, which can result in stubbornly holding onto beliefs despite rational arguments or contrary evidence. Understanding belief perseverance can shed light on why people may resist changing their minds, and it emphasizes the importance of critical thinking and open-mindedness.
