The Hump of the Camel

Cognitive dissonance is usually seen as the enemy of reason. For example, in the science-faith field, the old trope is that the Christian indoctrinated in the superstitions of the Bible, when confronted by the facts of science, becomes mentally scrambled and simply fails to perceive obvious realities. This criticism extends to the highest levels, for example in Jerry Coyne’s attempt to exclude Francis Collins from becoming head of the NIH some years ago, on the grounds that he was a Christian and therefore not scientifically reputable. But in fact, cognitive dissonance can often free the mind to pursue truth.

A couple of decades ago, when I still lived in the world of general medical practice, one of the local GP appraisers persuaded me and another GP, John, to run a course on spinal manipulation for the next generation of medics. Both of us had learned the same stuff, from the same pioneering doctors, John Paterson and Loic Burn, when we were young GP partners in the early 1980s.
