Actually, I'd say you have to have an IQ of 140 or more to admit your IQ among this bunch!
Agreed. I notice that you waited until post 140 to post this.
Three posts back you got a counterexample.
I happen to know an estimate for mine because my wife is a school psychologist and gave me the latest Stanford-Binnett by way of practice before evaluating a high-school senior for gifted placement (she figured she'd need to use the questions that normally only show up in adult testing).
I say an estimate because it was her first time using the new S-B which could have produced inaccuracies either direction, and it was late at night, so my performance on the digit-span task was certainly depressed by fatigue. (Judging by her management of the manual, I think I topped out, or almost topped out on all the subtests except that one, and the speeded symbol translation task.)
If someone explicitly asks me, I'll divulge it, but otherwise not.
