Supposedly, the mean IQ on Lesswrong is around 140. (Assuming that there is some relationship between median and mean in these rather unusual environs,) do you really consider more than half of the participants on this site too stupid to engage in intellectually stimulating discussions with you? I mean, what's with the 145+ cutoff for IQ? Even granting that you have, arguendo, a 155 IQ, do you really think someone with an IQ of 130 is to much of a dullard for romance?

Further... most people don't emerge from the womb committed transhumanists. Presumably, someone had to persuade most of them at some point. Perhaps you should be concentrating, not on men who are transhumanists, but on men who score high on the "openness to ideas" part of the Big Five?

ETA: The above reads sort of plaintive, in hindsight. So, in case it's necessary to spell it out, I'm neither looking for a companion nor in your age bracket. Just making suggestions in the form of questions.
