There was much derision on the last survey over the average IQ supposedly being 146. Clearly Less Wrong has been dumbed down since then, since the average IQ has fallen all the way down to 140.

The average person was 37.6% sure their IQ would be above average - underconfident!

Maybe people were expecting the average IQ to turn out to be about the same as in the previous survey, and... (Well, I kind-of was, at least.)
