Back around 2001, Jeff Shallit of the University of Waterloo asked me about collaborating on a critique of various claims made by William Dembski. Late in 2002, we had a completed manuscript. However, Dembski is not considered a hot topic most places, given that his claims have almost entirely appeared in popular rather than academic venues. In 2006, though, Glenn Branch became a co-editor for a topical issue of Synthese, which was to take up the subject of religious antievolution, and our submission there went through the revision process and finally page proofs quite recently. The paper is now published and available for about $35. Don’t believe the submission date listed there; our submission was complete as of early October, 2006.
Of course, the original, longer version is still available for free.

Abstract Intelligent design advocate William Dembski has introduced a measure of information called “complex specified information”, or CSI. He claims that CSI is a reliable marker of design by intelligent agents. He puts forth a “Law of Conservation of Information” which states that chance and natural laws are incapable of generating CSI. In particular, CSI cannot be generated by evolutionary computation. Dembski asserts that CSI is present in intelligent causes and in the flagellum of Escherichia coli, and concludes that neither have natural explanations. In this paper, we examine Dembski’s claims, point out significant errors in his reasoning, and conclude that there is no reason to accept his assertions.
