Creationists and intelligent-design boosters have a guerrilla tactic to undermine textbooks that don't jibe with their beliefs. They slap a sticker on the cover that reads, EVOLUTION IS A THEORY, NOT A FACT, REGARDING THE ORIGIN OF LIVING THINGS.
This is the central argument of evolution deniers: Evolution is an unproven "theory." For science-savvy people, this is an incredibly annoying ploy. While it's true that scientists refer to evolution as a theory, in science the word theory means an explanation of how the world works that has stood up to repeated, rigorous testing. It's hardly a term of disparagement.
But for most people, theory means a haphazard guess you've pulled out of your, uh, hat. It's an insult, really, a glib way to dismiss a point of view: "Ah, well, that's just your theory." Scientists use theory in one specific way, the public another — and opponents of evolution have expertly exploited this disconnect.
Turns out, the real culture war in science isn't about science at all — it's about language. And to fight this war, we need to change the way we talk about scientific knowledge.
