False Dichotomy

 

A false dichotomy is when you are presented with two choices and told that if one is wrong then the other must be correct but there are actually other choices.

Intelligent Design Creationists are very fond of this argument. They tell you that there are only two choices when it comes to explaining biology: either Darwinism or Intelligent Design Creationism. If a given feature of the biological world cannot possibly be explained by Darwinism, then God must exist and he must have designed the feature.

Here's Douglas Axe illustrating the false dichotomy on Evolution News & views [Let Science Be the Arbiter: A Reply to James Shapiro].

As an ID proponent, I've put forward the scientific case for thinking that the thousands of distinct structures that enable protein molecules to perform their specific tasks inside cells cannot have arisen in a Darwinian way. Moreover, the facts of this problem seem to preclude any naturalistic solution, Darwinian or not.

There is no crutch here. The aspects of protein structure that appear to preclude a naturalistic origin have been described in detail. If Shapiro or anyone else were to show in detail how these are overcome by a naturalistic mechanism, then my argument would fall and I would let it fall. But the reverse needs to be true as well. Scientists who personally side with naturalism have to be willing to let naturalism fall, as otherwise they would be guilty of using a crutch to prop it up.

This is actually an attempt to get around the charge of false dichotomy by extrapolating from a rejection of Darwinian explanations to any naturalistic explanation. If Axe is truly able to demonstrate that his "data" cannot possibly be explained by any naturalistic means then it follows logically that the only other type of explanation has to be supernatural. But what Axe is really arguing against is a Darwinian explanation and it's only his lack of imagination and arrogance that allows him to claim that no other naturalistic explanation is possible.

As we have seen time after time, the Intelligent Design Creationists do not have a scientific theory or any kind of scientific explanation for biological phenomena. All they have is criticisms of science—criticisms that are usually based on a lack of knowledge. When will we see an ID explanation of protein folding and function?
