 Independent of any given answer to the question whether delusions are beliefs, two conceptions of delusions divide the philosophical scene. One highlights the discontinuity between delusions and beliefs, and between neurotypical and neurodivergent cognition, with various consequences for what counts as pathological, but also for the availability of therapeutic options, such as cognitive behavioral therapy, for conditions characterised by delusions. The other view insists that there is continuity between delusions and beliefs, and attempts to gather data both suggesting that people with delusions reason in much the same way as people without, and that delusion-like ideas are widespread in the nonclinical population. Some studies have gathered a vast amount of empirical data about the temporal variations in delusions in context of psychopathologies, and the presence of delusion-like beliefs in the nonclinical population (e.g., Bentall 2003).
