Left‐handed men see better paychecks. There’s no causation here, folks. Left‐handed men who attended college make 17 percent more than their right‐handed colleagues. That’s because the IQ distribution of left‐handed people is flatter than that of right‐handed people — we’re more likely to be creative, yes, but we’re also more likely to have learning disorders. So by chopping off the bottom half of that curve you’d confirm what I could’ve told you already.
