What Makes a Belief a Delusion? Delusions, Thought Disorder, the TALD Scale

How do you actually evaluate a “delusion” in the room, especially when the belief could be plausible, culturally reinforced, or tied to mood or substances? In this episode, we break down a practical approach to psychosis language, why “fixed false belief” is often insufficient, and the interview questions that help clarify origin, certainty, flexibility, and function. We also use the TALD framework to expand beyond the usual linear vs circumstantial vs tangential model of thought disorder, then apply everything to a case vignette where a single supplement becomes the explanation for an entire life collapse. Educational and clinically focused.
