Our guest today is Nicholas Tilmes, whose research focuses on the intersection of cognition, law, and technology, ranging from disability rights to neurotechnology and AI. He holds an M.A. in Bioethics from NYU and a B.A. in Philosophy & Psychology from Cornell University. He joins us today to discuss his paper, "Semantic Vagueness in Psychiatric Nosology," published in the latest issue of the journal Philosophy, Psychiatry, & Psychology, which examines the areas of psychological diagnosis that are fuzzy, vague, or indeterminate, and philosophical ways this vagueness can be reckoned with.
