I have a bachelors 'of science' degree in Economics, with a minor in Finance. The only thing I really took away from that program is that there is virtually nothing scientific about economics. It hasn't moved beyond high-school physics ("imagine a frictionless surface with no gravity").

With that said, there is no real way to do economic 'science' - you cannot stage experiments with controls, or test the vast majority of hypothesis, aside from back-fitting against existing data.
