I have recently been referred to a chart of average IQ's which purports to demonstrate the correlation between average IQ within a state and the political leanings of that state. I had a hard time accepting this information for several reasons.
If a state has a "low" average IQ, then that must mean that "low IQ" is a strong genetic attribute of the state's population. I don't like this premise. The second possibility is that people of higher IQ simply move away. I am sure that this happens to a small degree, but not enough to create a huge deviation in the state's measured IQ, especially since IQ's are usually measured in childhood or young-adulthood, before most people have a chance to leave. The average IQ of each state should be close to 100.
Thankfully, Snopes.com has come to the rescue:
The chart's creator claimed to have been inspired by the book IQ and the Wealth of Nations and to have drawn his IQ data from the Ravens APM, but — save for the average income per state numbers, which were valid but outdated figures taken from the 1994 World Almanac — the chart was completely bogus. (The Ravens Advanced Progressive Matrices is not really a general intelligence test, nor do its publishers offer state-by-state test results data.) Nonetheless, a number of news publications (including the staid Economist) were taken in by the hoax — some mistakenly citing the information as having come from the book IQ and the Wealth of Nations, or even IQ and the Wealth of States — and published portions of the chart, and discussed it as if it were valid. (A similar hoax about presidential IQs produced similar media-fooling results back in 2001.)
Now, someone has dusted off the same chart and (omitting the economic data) applied it to the 2004 presidential election, keeping the primary gag intact: the "blue" (i.e., Democratic states) are all clustered at the top of the IQ scale, while the "red" (i.e., Republican) states are clustered at the bottom. Same hoax, different year. If 2008 produces another close presidential election as 2000 and 2004 did, expect to see this same joke again four years from now.
There is another, perhaps slightly more valid, estimate of "average IQ" for each state.
These estimates are based on SAT and ACT scores, and probably reflect the quality of education and test preparation in each state. Notice that Utah is slightly above average (not second from the bottom). As always, though, Mississippi is dead last.
Based on this data, I've put together a possibly more accurate chart:
