How delusions can uncover sources of harm and pathology: The epistemic value of interoceptive and unconscious information

Prevailing views of delusional beliefs frame them as pathological and harmful, leaving little room for understanding why delusions may emerge. Lisa Bortolotti’s book, “Why Delusions Matter,” offers a more compassionate perspective on delusions, framing them as adaptive and meaningful responses to crises. Many psychologists and philosophers have asserted that delusions can function as psychological defense mechanisms or adaptive coping strategies that protectively obscure painful realities. However, some delusions, especially those that arise in the context of traumatic experiences and psychosis, can be better understood as the body’s attempt to alert us to sources of harm and reveal, rather than obscure, important information. Drawing from neuroscience literature and the author’s personal encounters with psychosis and trauma, this article explores the ways in which some delusions can help us access interoceptive information from the body, uncovering sources of pathology, as well as previously unconscious information about harmful traumatic experiences. Ultimately, taking an epistemic justice lens to delusions, uplifts their value in revealing very real embodied experiences of the individual expressing them.
