There is all sorts of bull**** that happens in the matter of how the work of science is conducted. The social system that governs the conduct of science is most certainly subject to corruption. The work of people that one criticizes in a paper can end up being anonymously reviewed by the person you're criticizing.

The only shining light here is that the methods of science erode the corruption that can find it's way into the social systems which govern the conduct of scientists. Truth will eventually come out.
