ChatGPT occasionally lies. Truly. It fabricated a reference entirely when I was looking up Penrose and Hameroff. When I called it on it, it apologized, but refused to explain itself, although it said it would not do so anymore in the future (after I told it not to). WTF? Here is the false reference: Penrose, R., & Hameroff, S. (2011). Consciousness and the universe: Quantum physics, evolution, brain and mind. Cosmology, Evolution, and the Mind, 61-74.
