"""Business school should stick to teaching the mechanics of running a successful business as much as possible, and leave the psychology out of it."""
This is an interesting thought that I don't agree with. Management is simply the art and science of achieving results through people. If you broke management down into its major components, I believe that you would find that management is mostly rooted in psychology with a sliver of economics. If you leave the psychology out of it, there isn't much left.
