In fact, the very core of the scientific method is supposed to be skepticism. We accept arguments not because they come from people in authority but because they can be proven correct — in independent experiments by independent experimenters. If you make a claim that can’t be proven false in an independent experiment, you’re not really making a scientific claim at all.
And saying, “trust us,” while denouncing skeptics as — horror of horrors — “skeptics” doesn’t count as science, either, even if it comes from someone with a doctorate and a lab coat.
After a century of destructive and false scientific fads — ranging from eugenics to Paul Ehrlich’s “population bomb” scaremongering, among many others — the American public could probably do with more skepticism, not less.
If scientists want to be trusted, perhaps they should try harder to make sure that those who claim to speak for science are, you know, trustworthy. Just a thought.
