Richard Dawkins’ excellent article in the Times of London accurately and succinctly summarizes creationists’ strategies:
Science feeds on mystery. As my colleague Matt Ridley has put it: “Most scientists are bored by what they have already discovered. It is ignorance that drives them on.” Science mines ignorance. Mystery — that which we don’t yet know; that which we don’t yet understand — is the mother lode that scientists seek out. Mystics exult in mystery and want it to stay mysterious. Scientists exult in mystery for a very different reason: it gives them something to do.
Admissions of ignorance and mystification are vital to good science. It is therefore galling, to say the least, when enemies of science turn those constructive admissions around and abuse them for political advantage. Worse, it threatens the enterprise of science itself. This is exactly the effect that creationism or “intelligent design theory” (ID) is having, especially because its propagandists are slick, superficially plausible and, above all, well financed.
The standard methodology of creationists is to find some phenomenon in nature which Darwinism cannot readily explain. Darwin said: “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.” Creationists mine ignorance and uncertainty in order to abuse his challenge. “Bet you can’t tell me how the elbow joint of the lesser spotted weasel frog evolved by slow gradual degrees?” If the scientist fails to give an immediate and comprehensive answer, a default conclusion is drawn: “Right, then, the alternative theory; ‘intelligent design’ wins by default.”
Notice the biased logic: if theory A fails in some particular, theory B must be right! Notice, too, how the creationist ploy undermines the scientist’s rejoicing in uncertainty.
