the average IQ in the U.S. is 98

[Dreamer Tatum]

59. I would wager the average DU IQ is pretty much exactly what the national average is.

Know why? Because it's probably true. You have exactly zero basis to claim that DUers are much smarter than
average because (a) you're biased to think it's true by your own design, and (b) if you ran across someone
or someones who are objectively of high IQ, any lack of kinship you feel with them would probably cause you to dismiss their intelligence. Any diversion on their part from any of your closely held feelings or beliefs would likely cause you to call them an 'idiot,' 'moron,' and so forth.

Moreover, political conviction, activism, and earnestness does not imply nor is implied by supra-normal intelligence.
"I believe in science rather than in faith," for example, is not an indication of intelligence. It's an indication of
belief and preference. "I think Sarah Palin is an idiot" is not a magical incantation that confers intelligence, nor does
it display much.

Furthermore, on what basis could you possibly be surprised by "how low the average IQ" is? IQ isn't an absolute
measure, nor are there any basic human functions that require a minimum IQ to perform. Also, I can make an affine, order-preserving transformation to the IQ scale so that a score of 98 is indicative of historic genius or complete idiocy. Choose which you'd like, and I'll get to work.

I'm sure there are geniuses on DU. There may be many of them. I'm sorry to report, however, that there are almost certainly some with sub-98 IQs as well, and I would bet a lot of money that the DU mean IQ is around average.
