I'm surprised to read that anyone in the field still imagines that we humans make decisions in any coherent fact-related way. Sapolsky's Stanford lectures (introductory biology of human behavior) are enough to make it clear beyond any doubt that nearly all our decision-making occurs as a result of factors that have little to do with reason-based processes. Add to this the enormous literature that's emerged over the last 30 years regarding the coherence (or rather, lack thereof) in human behavior (of which decision-making is a part) and one is left with the conclusion that we're mostly just sleepwalking through our brief existence.
