I've also heard, "Trust in the science." (emphasis mine).

I find this second form even more troubling. IMHO, it implies that there's only one conclusion that (real) science can reach, and the audience has been shown that conclusion.

To doubt that particular conclusion (no matter how badly researched) is to doubt the scientific method itself. It's implicitly a conversation stopper.

That said, I'm making a lot of guesses about the intentions of whoever says that stuff. So maybe I'm being unfair.
