I knew quite a few really bright kids that were very popular in school. Okay, maybe not so much the math & science prodigys (I'm sure there were exceptions) but I'd say that generally, really dumb people didn't fair all that well either. Infact, I'd say that one of the bigger popularity criterias I noticed was confidence. Popular kids were typically confident in their interactions, willing to put themselves out on a limb, etc. Sure there were a few elite groups of movie-star bitches that drew envy, but I wouldn't categorize them as "popular" because they only ran within their own small clique. In elementary my school practically ostracized the gifted and talented kids.. but this was a weird construct created BY the school. I got thrown into GT in 5th grade, seperated from all my buddys, and it was a total nightmare. The teacher over the program WANTED an elite group. Had something to do with teaching disagreements with other teachers. And the school WANTED him as a teacher. So they gave him his own dam building, and we never left it. Never got included with other class sports etc. Then, it seemed like the GT kids always got the lead roles in school plays (okay, because tbh the GT kids read a little better, memorized lines better, etc.) and it caused quite a bit of resentment with other 10 and 11 yr olds. But looking at later jr. high/highschool development, there were plenty of intelligent, popular people. AND, not every dumb kid was cool. Lots of idiots that were as smooth as sandpaper. Popularity correlates wtih social skills, which if anything, I might argue the opposite of the OP. It can take tremendous intelligence to successfully interact with the masses.
