Indeed, this has been found to be true. Environment does indeed have an impact on adult IQ, albeit a small one. I'm sure this is true to some extent. But what exactly are you trying to prove by saying this? The farthest you're going to get with this thought is that environment matters. Well obviously it does. I never said it doesn't. So... good for you! Environment matters! Whoohoo!! A little bit. You're very likable, intellectually stimulating, interesting, mature, definitely not overemotional, uhmm, interesting, uh, likable, good looking, sock-sniffing, sexually arousing, uhm, and a good, uh, all-around chap. Honestly though. I can take insult. I neither take insult personally in real life, and especially not in Internet forums. In fact, if properly executed I can really appreciate a good insult. If it exhibits wit, finesse and creativity, then it's great. But the problem is that you're doing it all wrong. It's really pathetic. Actually, this is one of the worst insults a guy can get, because you're saying "you're such a douche, I'm not even going to try and insult you properly--or maybe I'm the stupid, uncreative douchebag--either or." Next time you insult me, try to catch me actually saying something stupid and then accentuate my stupidity or the absurdity. In other words, don't do what you just did. Basically what you did was make a dumb, completely ineffective argument and then said "You dumb." Honestly, please kill yourself. Are you saying because you personally don't think I know what a significant digit is that I'm the one who's avoiding reading? What the fuck? Again. Please kill yourself.
