The authors seems to imply that that Christopher Langan who scores extraordinarily high on IQ tests and who is developing a Cognitive-Theoretic Model of the Universe" (CTMU), is somehow dumb or ill informed for believing that the 9/11 attacks and subsequent collapse of the twin towers and world trade centre building 7, was planned. Regardless of whether that is true or not, the author of the article takes direct aim…
It seems to me you're offended that the OP implies that, e.g. Bobby Fischer wasn't good at non-well-defined problems. I would be interested to know why is that. To clarify: I don't like the way they phrased it either (it was too judgemental), it just didn't bother me so much.
Remember, people are still debating the JFK assassination, and those that don't believe the mainstream accepted narrative that Oswald single handedly fired those shots, considered crazy.
It bothers me, not that it makes any difference. I just wanted to point attention to it.
