Whenever I hear stuff like "the science is settled" or some other appeal to the infallibility of a scientific "truth" in the context of any one of the unserious sciences* like evolutionary biology or climate warming, then I know that what I'm hearing is decidedly not based in demonstrable fact, but is rather something that requires a vocal consensus and the browbeating of "denialists" in order to bolster the confidence above a level that should be appropriate for the evidence available.
(* The serious sciences being mathematics and physics, which are actually capable of direct, unequivocally true proofs and subject to a far greater extent of rigor than, say, the hunches and anecdotes of evolutionary biology.)
