So it pays to be skeptical when it comes to the claims we hear every day. For example, most of us wouldn't pour a newfangled alcohol solution into our gas tanks, unless it had been widely tested, widely publicized, and widely accepted. But we would never treat our TV sets that way. Sure, scientists sometimes lie, but usually for political reasons. But real science is, by nature, agnostic.
Good science is a continuing discussion between many people.
Genuine science opens itself to test and, if needed, refutation.
