There wasn’t room in my review of James Powell’s book The Inquisition of Science to comment on one or two aspects of the book in the detail I’d have liked, and I’ll take up one in particular in this supplementary post. In a chapter titled The Anatomy of Denial he has an interesting short discussion on the motivation of the scientist deniers. The denial campaign depends on having some scientists to whom it can point in confirmation of its arguments, and they have duly been forthcoming, albeit few of them actively engaged in climate science. Powell’s analysis confirms what others have discovered, but he puts it freshly and it’s worth highlighting regularly.

Some of the scientist deniers he sees as simply contrarian by nature, revelling in being different. Every field of science has had its contrarians with provocative ideas. Most of the ideas may be wrong, but even so they can advance the science by stimulating new experiments and new questions. Contrarians may sometimes play a valuable role as devil’s advocate, but they may also simply and repeatedly be wrong. He notes wryly that if Freeman Dyson were to accept global warming no one would pay any attention to him since he would merely be one of tens of thousands contributing to the scientific consensus, almost any one of whom would know as much as he. By denying it, he lands on the cover of the New York Times Magazine and is lauded for intellectual courage. In Powell’s extended discussion of Dyson’s denial in an earlier section of the book he quotes Dyson acknowledging that Hansen, whom he accuses of consistently exaggerating the dangers of global warming, has all the credentials established by his hundreds of published papers.
