What does "confirmation bias" refer to in the context of investigations?

Confirmation bias refers to a psychological phenomenon where individuals tend to favor information that confirms their preexisting beliefs or hypotheses while disregarding or minimizing evidence that contradicts those beliefs. In the context of investigations, this means that investigators might focus on evidence that supports their initial theories or assumptions and overlook or dismiss evidence that could suggest an alternative interpretation. This bias can lead to a skewed understanding of the facts and may compromise the integrity of the investigation. Recognizing confirmation bias is crucial for investigators to ensure that they examine all evidence impartially and make informed decisions based on a comprehensive view of the case.
