Well, <85 is functionally retarded. For all intents and purposes.
The AAMR only changed it to <70 for political reasons that were good, well-intentioned reasons in 1973 but that it's better not to discuss now; they no longer really apply to the present-day situation.
A person with an IQ <80 would be... difficult to communicate with in this context, to say the least.
Yes, we've had a few; perhaps 3 or 4 during my tenure on this forum.
But in all honesty... heh. Well, you don't see a lot of "mentally retarded forums" on the internet, do you? There are some forums for parents of mentally retarded children, but the mentally retarded themselves- even the high-functioning, educable mentally retarded- don't tend to express themselves real well when it comes to the written word. Nor do they tend to understand written political commentary very well. Nor do they tend to understand the subtleties of social interactions on an internet forum.
But as few people as there are in the world with an IQ <80... that's about how few people there are with an IQ over 120. Yes, privileged white people are more likely to be on the higher end of the scale, while underprivileged minorities are more likely to be on the lower end of it. That's because the test is classist and racist, like much else in our society.
Collectively, this forum is certainly more than clever enough to keep me entertained, but nothing about it screams "Genius".
At least not to me.
I never would've guessed, in all these years, that I was participating in a forum populated almost exclusively by the finest minds in the country, if not the entire world.
I still don't believe it.
And the defensiveness I'm sensing makes me lean away from "honest mistake" and towards "deliberate deception".
