What delusions can tell us about the cognitive nature of belief
Delusions can sometimes turn into strongly held beliefs.
Beliefs are convictions of reality that we accept as true. They provide us with the basic mental scaffolding to understand and engage meaningfully in our world. Beliefs remain fundamental to our behavior and identity but are not well understood.
Delusions, on the other hand, are fixed, usually false, beliefs that are strongly held but not widely shared. In previous work, we proposed that studying delusions provides unique insights into the cognitive nature of belief and its dysfunction.
Based on evidence from delusions and other psychological disciplines, we offered a tentative five-stage cognitive model of belief formation.
