The main hitch to that type of progress is that there is too much infighting between which model is right in neuroscience, and which model is right in psychology, nobody has a sturdy enough raft to set sail into the unknown between them. How I would go about it would be to risk being wrong and start off from the most likely track in psychology, and invent the factors that, if followed through, would result in a currently accepted model of psychology. Like flavor for quarks. It would necessarily be mostly theoretical until the answers it gives become useful. Then, repeat as necessary.
