Sure, but that doesn't mean "a weighted combination of feelings" is an accurate description of the true process. That's tendentious and speculative. What I think we can be sure of is that there are parts of our decision making that we are not consciously aware of, but precisely because of that, one should be cautious of assuming how it works even if you're not doing it by reflex. Psychological explanations are the rationalizations that people make after the fact.
