Reading reviews of the Ben Stein trainwreck Expelled: No Intelligence Allowed (which is a funny title, but probably not in the way they intended) is good fun. I suppose there's no definitive way to determine if a film is good or bad, but here's a hint: it's not looking good when you make a piece of red meat for ultra-conservative nutcase Americans and Fox News calls it "sloppy, all-over-the-place, poorly made (and not just a little boring) 'exposé' of the scientific community" and calls its director "either completely nuts or so avaricious that he's abandoned all good sense to make a buck." Good times.
Rather than dignify the creationist nonsense that Stein regurgitates, let's talk about the amusing lengths to which creationism advocates go to turn their little fairy tale into a legitimate science. Specifically, the effort to sell this to the courts as Intelligent Design: All Scientific and Shit revolves around the idea of "irreducible complexity." It is, of course, based on a ridiculously transparent logical fallacy – the Argument from Incredulity.
This fallacy is basically the assertion that something cannot be true (or should be presumed false) because one personally finds it impossible, implausible, or incomprehensible. In other words, "I don't believe that, ergo it isn't true." If this sounds like a fairly silly thing upon which to base an entire belief system and sociopolitical movement, you're not alone in your skepticism.
Irreducible Complexity is the argument that certain biological processes are too complex to be explained by evolutionary theory. Of course "too complex to be explained by science" means that the correct explanation is provided by Genesis.** Here's the problem, though…there are plenty of explanations for every phenomenon purported to support this theory. Creationists simply respond that these explanations are not plausible (ginandtacos preferred whipping boy, Michael Behe, provides a great example of this logic in Kitzmiller v Dover). In other words, "I don't understand it / I don't believe it, therefore it is not true."
Try it out! It's fun. For example, a friend of mine once explained to me how the internet works. I did not understand a goddamn bit of it. It just went directly over my head. Therefore….there is no existing theory that can explain how the internet works except "God made it." Neither can I believe anyone would use an argument this stupid. Therefore it can't be happening. The copious evidence to the contrary that is created every time a creationist opens his or her mouth does not persuade me.
