There is an interesting diversion to be made along these lines. Nick Land, who has written up a series (The Dark Enlightenment) about Moldbug and the neo-reaction in general, has just written this, in which he posits the politically-assisted decoupling from reality as a progressive eschatology:
"The unforgivable crime is to accept that there are consequences, or results, other than those we have agreed to allow."
This meme, a seriously morbid distortion of epistemology, is common to many adaptive belief systems, but I would propose that it is more crucial to progressivism than any other.
Land is a little horrifying in his Nietzchean/Stirnerian lack of barriers, to be honest.
About accepting/not shrinking from shocking facts about reality: I see two basic types of failure modes here - firstly, denying the presense of any given horror (like e.g. innate group neurological differences - race, gender, etc - creating inherent power and knowledge differences in a society and making brutal unyielding inter-group hierarchy such a society's "natural", least costly to maintain and most economically productive state) is indeed more common to ...
I've seen several people on Less Wrong recommend Mencius Moldbug's writings, and I've been curious about how he became so popular here. He's certainly an interesting thinker, but he's rather obscure and doesn't have any obvious connection to Less Wrong, so I'm wondering where this overlap in readership came from.
[EDIT by E.Y.: The answer is that he's not popular here. The 2012 LW annual survey showed 2.5% (30 of 1195 responses) identified as 'reactionary' or 'Moldbuggian'. To the extent this is greater than population average, it seems sufficiently explained by Moldbug having commented on the early Overcoming Bias econblog before LW forked from it, bringing with some of his own pre-existing audience. I cannot remember running across anyone talking about Moldbug on LW, at all, besides this post, in the last year or so. Since this page has now risen to the first page of Google results for Mencius Moldbug due to LW's high pagerank, and on at least one occasion sloppy / agenda-promoting journalists such as Klint Finley have found it convenient to pretend to an alternate reality (where Moldbug is popular on LW and Hacker News due to speaking out for angry entitled Silicon Valley elites, or something), a correction in the post seems deserved. See also the Anti-Reactionary FAQ by Scott Alexander (aka Yvain, LW's second-highest-karma user). --EY]
