Science is.

Umm. So here's the thing. The scientific method is the best system we have for learning things about the world around us. The problem is scientists are humans.

There are papers published in reputable journals written by lobbyists and special interests to use the trappings and gravitas of science to push their agendas. There are medicines on the market that mostly or entirely don't work because they were in use before the FDA was a thing. There are lots of papers written by academics entirely to keep the grant money coming, or edited by university management to prevent casting the school in a bad light.

Science, as an institution, is not infallible, and should be examined and audited.

And indeed, a core principle of the scientific method is incredulity. A scientist publishes something, you're supposed to say "That doesn't seem right, I don't think I believe it." and then repeat the experiment to see if you get the same result.
