I agree with you. Decision are very plausibly classical. Actually, even more so if the brain was a quantum computer, as we would use quantum effect to enhance the classical probabilities of getting what we search. > In general, decisions are not choices from a set of possibilities in > superposition, which would be the only way in which the proposal could make > any sense.
