It would be nice if there were some individual figures to go along with the IQ map's averages. Saying that states can vary by +/- 5% of a score of 100 is enough to be interesting, but you can't really draw any conclusions from it without a lot of speculation.
(If the shades of green matched the overall IQ scale instead of being used comparatively, the map would look far less dramatic.)
