used to try to re-engineer society and human behavior
Try? I'd say they are having many successes.
As far as re-engineering society using psychological and sociological theories, if any change at all is the measure of success, you are right. But is a valid scientific theory permitted to have so many unintended consequences? ...and outright failures? So are these theories scientific?
As far as changing human nature, there are no successes, intended or otherwise. And IMHO, there won't be any.
What exactly is "human nature"?
