Think this is what we are doing. Few of our 'decision' are free, most are genetic. Genetic being, i was born with some propensity for some particular hormone, which leads to some particular decisions. It is completely beyond our ability to choose, because all of those pre-cursors already chose for us and it feels free. Of course we have free will, we just don't have free will to choose what we will. Schopenhauer had it right.
