I don't mean to burst anyones bubble here but if you did your 'iq test' on one of those ads that request a phone number, txt or email? those aren't actual iq tests and the answer is always 137 or 140 or something close to that so people don't get offended, feel good about themselves and buy shit after..
Most people are unable to determine other peoples IQ based on talking with them briefly or how they post on message boards, mostly because they get emotionally involved and assume anyone who disagrees with them is stupid. You can make an educated guess however if you look in the right places though.
