Result: average IQ for red states vs. blue states was essentially the same (red 99, blue 99.5). Conclusions: Are liberals smarter than conservatives? Some social scientists sure think so. Are blue states smarter than red states? Sadly for us cyanophiles, no.

But here's the most significant data point, I think: in the purple states — the ones that swung back and forth — the average IQ according to Una's spreadsheet was 100.9, appreciably above that for either the blue states or red states. In other words — and this has the shock of truth — the people in the purple states weren't rigidly liberal or conservative, but rather had enough on the ball to consider the choices before them and occasionally change their minds.
