First there was this chart where average US state IQ was listed in order. On that chart, states that voted in majority on Al Gore in the 2000 election were coloured blue and those states that voted in majority for George W. Bush were coloured red. See it for yourself! (IQ isn't really a measure of anything useful but it's funny.)
Then there's this study which lists states and their "Percent of People With a Bachelor's Degree or More". Clearly it shows where people are most likely to have a college/university education. Now, on metafilter they conclude that:
"... for those who are politically curious, of the top 15 states with Bachelor degrees 11 went to Gore, while 13 of the bottom 15 went to Bush."
One must of course admit many flaws in this logic but there is undoubtedly a correlation there.
The real iq test is whether or not you believe this bit of agitprop.
Did you fail?
