I recently read Flock of Dodos (no relation to the movie of the same name). It’s a hilarious no-holds-barred send-up of the lies and poor reasoning of the intelligent design movement. I was particularly struck by a quotation from William Dembski’s Intelligent Design.
We are dealing here with something more than a straightforward determination of scientific facts or confirmation of scientific theories. Rather we are dealing with competing world-views and incompatible metaphysical systems.
That cuts to the essence of what we are confronting on Science-Based Medicine. We are trying to evaluate the science behind claims that are often not based on science but on beliefs that are incompatible with science. The claimants are happy to use science when it supports them, but when it doesn’t they are likely to unfairly critique the science or even to dismiss the entire scientific enterprise as a “materialistic world view” or “closed-minded.” We are talking at cross purposes. How can we communicate if we say “this variety of apple is red” and they insist “it feels green to me”?
We get frustrated when we show these folks the scientific evidence and they refuse to accept it. Homeopathy is not only implausible, but it has been tested and has failed the tests. Yet proponents refuse to acknowledge those failures and still want to talk about data from the 19th century and make claims for the memory of water. We have to realize we are not even speaking the same language. We are trying to play a civilized game of gin rummy and they are dribbling a basketball all over the card table. Before getting into a debate, doesn’t it make sense to define what game you’re playing and what the rules are?
Science has been a very successful self-correcting group endeavor. It wouldn’t be successful if it didn’t follow a strict set of rules designed to avoid errors. [Note: there are no rules written in stone; I’m talking about conventions that are generally understood and accepted by scientists, conventions that grow naturally out of reason and critical thinking.] If proponents of alternative medicine want to play the science game, they ought to play by the rules. If they won’t play by the rules, they effectively take themselves out of the scientific arena and into the metaphysical arena. In that case, it is useless for us to talk to them about science.
