I hope Matt Ridley's life insurance is paid up because this piece will probably make some of the always-right-thinking, consensus-enshrining people very angry.
(But, if he's lucky, maybe they'll completely ignore it, as they sometimes do with careful, modest, well-reasoned arguments against their position.)
I'd agree with the commenter who wrote, "Matt, this must be the best summation of the sceptical position that I have ever read. Well done."
