Stating the obvious -
'Right wingers are "less intelligent"'
(Headline in today's "I on Saturday")

The research leading to this conclusion is supposed to have been publicised in a periodical called "Psychological Science".
One problem for me -
If the research was commissioned by right-wingers then the results would have been suppressed. If commissioned by left-wingers then they were demonstrating a want of intelligence, chucking their money away to learn what they should have known and been relaxed enough not to need to go in search of external confirmation.
Value-free academic research conducted by disinterested individuals or organisations? I chortle at the idea.

Maybe it's a wind-up, to induce an epidemic of coronaries among fascists, crypto-fascists (aka Mail readers), racists, tories, etc.
