Thank you for your helpful response. It would take a long time to explain the psychology involved on my part, but I do indeed have a fairly thorough understanding of the social psychology involved on the part of others. Sometimes I legitimately expect persons to understand what I am saying and am surprised when they do not, but most often I do not anticipate that folk will understand what I am saying and am unsurprised when they do not. I often comment anyway for three reasons. First, because it would be prohibitively motivationally expensive for me to fully explain each point, and yet I figure there's some non-negligible chance that someone will find something I say to be interesting despite the lack of clarity. Second, because I can use the little bit of motivation I get from the thought of someone potentially getting some insight from something I say, as inspiration to write some of my thoughts down, which I usually find very psychologically taxing. Third, because of some sort of unvirtuous passive-aggression or frustration caused by people being uncharitable in interpreting me, and thus a desire to defect in communication as repayment. The latter comes from a sort of contempt, 'cuz I've been working on my rationalist skillz for a while now as a sort of full-time endeavor and I can see many ways in which Less Wrong is deficient. I am completely aware that such contempt--like all contempt--is useless and possibly inaccurate in many ways. I might start cutting back on my Less Wrong commenting soon. I have an alternative account where I make only clear and high quality comments, I might as well just use that one only. Again, thanks for taking the time to give feedback.
