I believe the above comments had essentially the right idea. He is trying to say that since most human cognition is subconscious and governed by emotion (i.e. we don't have direct access to it, per se) then it's philosophically wrong to try to formulate processes for decision making in the Bayesian/decision-theoretic sense. He claims that not-3 implies that 1 is useless and 4 will only give incorrect results, where I've borrowed the numbered propositions from RichardKennaway's comment.
I have recently been corresponding with a friend who studies psychology regarding human cognition and the best underlying models for understanding it. His argument, summarized very briefly, is given by this quote:
I am having trouble synthesizing a response that captures the Bayesian point of view (and is sufficiently backed up by sources so that it will be useful for my friend rather than just gainsaying of the argument) because I am mostly a decision theory / probability person. Are these works of psychology and neuroscience really illustrating that human emotion governs decision making? What are some good neuroscience papers to read that deal with this, and how do Bayesians respond? It may be that everything he mentions above is a correct assessment (I don't know and don't have enough time to read the books right now), but that it is irrelevant if you want to make good decisions rather than just accept the types of decisions we already make.
