The Smug Baldy Speaks

I made this response on Kevin Murrell’s blog after he made the following vacuous claim:

In the movie Expelled, Ben Stein gives a compelling argument for Intelligent Design.

Having not seen the film yet, I can’t really comment on how compelling his argument actually was, but I suspect that it wasn’t a compelling scientific argument. If you follow the Intelligent Design controversy at all, then you’re probably well aware that ID lacks all the hallmark features of a true scientific theory. The two most critical components that ID lacks are the requirement that the theory be potentially falsifiable (ID is not), and that it leads to testable hypotheses (ID doesn’t make any).

Interestingly, I see many who mistakenly claim (as I’ve heard Stein claim in the Expelled trailers) that the “scientific community” (interestingly, not individuals, but the community as a whole) have an almost religious belief in Evolution, which is absurd for anyone wanting to call themselves a real scientist. Indeed, this would be equivalent to saying that the religious community has faith because of the results of careful experimentation.

No, as I’ve written before, scientists don’t believe in Evolution - they accept it provisionally as good theory. If Evolution were really such bad science, maybe as some in the ID community would like it to be, then it would not withstand the internal pressure of real scientists who really test it. So far, the testable hypotheses that Evolution has made have supported it. One of the implications of Evolution, unknown even in Darwin’s time, was that the Earth has to be much older than Darwin originally believed. We now have confirmation from multiple independent sources that point to a very old earth, unless you would prefer to reject several distinct branches of science. Evolution also predicts the relative orderliness in the fossil record - and the discovery of just one counter example would completely destroy the theory. Interestingly, Evolution also predicts the genetic differences found between humans and other major primates. The recent discovery that the human chromosome 2 is a fusion of two distinct chromosomes found in the great ape species not only accounts for the the observation that humans have 23 chromosome pairs and the apes have 24, but also supports the notion of a common ancestor. If the genetics worked out any other way - then it would be reason enough to toss the theory in the bin.

The principle issue I have with ID is that, since it isn’t really science, members of the ID community have attempted to get it into our public school science classes through the tactic of redefining science itself. I think scientists take issue with that, and rightly so. Again, the equally absurd tactic would be to force churches to teach Evolution in sunday school classes by successfully redefining what the tenants of christianity are.

Nope - the Expelled hype aside, it all comes down to this: Evolution isn’t “special” in a scientific sense. It makes predictions that can be tested, and if those tests fail, then the theory will be discarded for something better. I can guarantee, however, that ID isn’t a viable alternative, since, well, it isn’t really a theory in the scientific sense of the word. And THAT’S what matters to scientists.
