It's a perfectly legitimate dismissal. People talking about how awesome they are has well known spiral qualities, and isn't that useful. As with the start of this comment chain: The burden of why we should talk about this is on people who think we should, as the reasons why we shouldn't are obvious: It doesn't appear to serve any use and is at risk of becoming nothing more than backpatting.
Mistake 1 - I am intelligent = I am awesome.
Mistake 2 - It's useless to talk about a trait that makes you "awesome".
Discussing how to capitalize on a positive trait seems quite useful to me, and the more "awesome" the trait, the more potential mileage of exchanging information on how to exploit it. It's a trait where we have a comparative advantage (and some disadvantages) far out on the tail of the distribution. It's stupid not to discuss it in the rare circumstance where we have a large sample size far out on the tail of the distribution, just where we need the data.
The latest survey shows that the average LessWronger who entered his SAT or ACT is roughly in the top 0.11%. This is insanely high. For comparison, top 2% can be Mensa members. I do not know the correlation between SAT/ACT and IQ, but I know it's fairly high. Anyway, I'm very curious to see the average score on a real, culture-fair IQ test. Those are the only two tests that are free, online, correct and culture fair, from what I know.

Many people would prefer not to have people knowing their scores. That's great, but please please please do post it anonymously. Especially if it's a low one, but not if it's low because you rushed the test.
JCTI might take a while, so I recommend keeping your answers on Notepad in case you want to leave it and continue later.
Edit: I have included polls, thanks to the commenters.
