In other professional disciplines particularly ones that require some sort of certification there are ethics tests and ethics committees. For example if your trying to get a CFA half of the test is ethics. Likewise for becoming and being a lawyer.

Given the importance of academia and its impact on policy in general perhaps something similar should exist?

I'm not sure if ethical tests and committees curb bad behavior but it could be a start or at least improve awareness. Maybe there is even something like the above already in place for academia that I'm unaware of?
