Why are scientists so dull? Because interesting people are selected against.

Also worth noting is Charlton's political agenda: self-proclaimed reactionary Christian, with a self-published book about the evils of political correctness. (Note his drive-by on anthropogenic climate change in the first couple of paragraphs, as he's warming to his topic ...)

In view of this background, I tend to discount his public pronouncements as increasingly eccentric axe-grinding.
