No doubt he did make that blunder. I would say that Complex Specified Information (a notion not invented by Dembski but by Leslie Orgel, and also used by Jack Szostak and Robert Hazen) is not a senseless notion. It’s just that having it does not prove that something is designed. At Panda’s Thumb I recently posted an argument that using Algorithmic Information Theory in this context is useless. But using a component of fitness does make sense and we can see that lots of adaptations have high specified information. Perhaps we could discuss this in a special thread at PT.
