IQs (warning: self-reported numbers for notoriously hard-to-measure statistic)

Yeah, I'm extremely skeptical of the IQ data. Assuming a standard mean=100 SD=15 test (although at least one respondent says he took a test with SD=24), our reputed median is above the 0.003th percentile. I don't think any public blog is that elite.

ERRATUM: Oh, dear. I meant 99.7th percentile.

I'm skeptical of the IQ data because of the number of IQs above 140. Most IQ tests don't measure well above IQ 140, and so even if we have that many truly exceptional people, I would not expect it to show up in their measured IQs.

The person who administered my test told me it was inaccurate above 150, and then told me my result was high enough to be somewhere in the inaccurate range, so I explicitly mentioned that it was an "at least" figure.
