Science work from a university or similar institution usually goes through an Institutional Review Board (IRB) meant to screen for conflicts of interest.
I read education journals from time to time and it's rather common for researchers to apply some intervention to a classroom setting and then report, to their probable dismay, that it did not produce any measurable benefits.
