We break it by doing what used to be done: Demanding honesty, hearing criticism, building your arguments so that even a layman can repeat the steps you took to reach your conclusions -- and understanding that accepted science is not absolute science, as we discover new things every day that creates questions about or outright invalidates old science.

As well as, yes, stopping with the "grants" because "grants" are demonstrably just there to come to conclusions that the person giving wants.

We only fix it by ousting people from the field when they refuse to hear questions about their methodology or results, and shunning people who rise to their defense by saying that we aren't smart enough to "get" it.
