Confirmation bias is a systematic error in inductive reasoning whereby one interprets, remembers and comprehends information in a way that confirms their pre-existing beliefs or explanations. Typically, someone displaying confirmation bias is selective with information, most notably with emotionally relevant topics. Confirmation bias can therefore lead us to build strongly held views that could lead to some unbalanced perspectives. Some commentators suggest that confirmation bias is unintentional rather than a decisive action, aimed at allowing us to make sense of new information heuristically. It is proposed that consistently building alternate hypotheses in parallel is demanding on the mind and does not readily allow one to make sense of complex information.
