sorry I missed the replies to my post
I’ve found that people are quite respectful of and deferential to people rude enough to do so. However, if a person quietly demonstrates intelligence, people mistrust them and suspect them of elitism.
Look at recent American Presidents for examples. None in my lifetime had a particularly intelligent persona. Look at some of the candidates who lost in either primaries or the general elections. The most intelligent appearing candidates never win!
No, I think most people would just ignore the thread, especially those who are not stunningly good-looking. They would recognize that some topics are difficult to discuss IRL, and leave the others to their discussion. Isn’t one of the draws of message boards that one can discuss sensitive subjects?
[They would also worry about appearing homely and bitter about it, by making fun of the Pretty Ones. No one worries about appearing bitter by making fun of the Smart Ones.]
Oh, yeah. I still burn when I remember how one professor humiliated me in front of several other students. [And I was the only one there who aced an earlier, ball-busting course of his. Even my lab partner started questioning me, after I’d pulled him along … but I digress.]
Still, I can not cry you a river. I wasn’t tortured much; I went to good schools and the other kids were either smarter than me, or wanted to copy my math homework. The attitude I described was exhibited by friends-of-friends, cousins, and two absolute bitches who were mothers of my friends. People easy to avoid.
However, as an adult, I have found that many people don’t warm to me until they perceive me as disorganized or plain. Then I fit into a stereotype to which they feel comfortably superior, and then they do warm to me. People like me. I can be fun.
I like people. I like fun, witty, nice people who aren’t as smart as I am, because they are fun, witty, or nice. They also find me useful; I like that. I get an ego-charge and they get a problem solved. Win-win.
I like people who are smarter than I am, because I can always get them to be interesting [unless they’re physicists; I’m not good with physicists]. I really like hanging with people smarter than I am (especially if they are plain or disorganized). 
Re: I.Q.
Aren’t there two commonly used scales, one which is ten points higher?
