Billw’s expertise is specific to the area of psychology, which I think is more dependent on professor interaction and classroom interaction of students with each other. Humans somehow defy being modeled by a system of simultaneous differential equations.

Full disclosure: I am not one of those proles. I admire those who have a good handle on HJB theory but tragically, I suck.
