The author does a horrible job of distinguishing between odds and probabilities. I would expect "the set of people who are able to clearly recognize that he is not talking probabilities" and "people who did not already know about Bayes' theorem and gained significant knowledge from the article" to have a rather small intersection. Not only does he not explicitly draw attention to the distinction between odds and probabilities, he repeatedly uses a slash rather than a colon, and in one case uses the preposition "in" rather than "to".
