I think I was confused and wanted to pick out that this notion of “pseudo-rationality” actually is an entangling of at least two distinct behaviors that I would treat completely separately, a la geeks, mops, sociopaths:
“Sociopaths” trying to game the rationalist social ladder for power without actually learning rationality.
“MOPs” trying to get as much out of rationality as possible with minimal effort and critical thinking.
I think I was mostly responding to the first set of things.
This article reminds me of “Uncritical Supercriticality”, where people argue in favor of “rationality” a little too hard. Could also be either an innocent mistake, or it can be done strategically for social reasons. (If it’s the latter, you are likely to put “rational” in the name of your website, because that gets even more social points.)
