First of all let me start by saying this shit is the reason we need sources. Fuck me. Fist of all he got the name of the book wrong. It's "Maps of meaning". Not "Map of meaning". I don't know if the title was changed afterwards but a quick google search of the book (or if you had read it even) would tell you the book is now refered to as "Maps of meaning".
That begs the question of how much can we trust the hearsay of someone who publishes an article and gets the freaking title of the book wrong out of all things.
Regardless of that, let's assume the sources are correct. His conclusion about being a created fad in late 2016 and getting viral because of clickbait psychology that was in line with popular "youtube academics" is not wrong imo. Having watched him and what he talks about, it's pretty clear he uses low amount of personal clinical examples, which makes me suspect but not confirm, that he has low clinical experience. Academia and teaching seemed to be his forte.
But one thing that I will dispute is that IF (sources needed again) he scored low on LSAT that doesn't mean he is not smart (IQ wise I mean). People can go through periods of depression or apathy and still take the test, and score low even if they are smart. Jordan mentioned he was having an alcoholic phase when he was young, so that can fit too. Also, the non-neutral language in the text really makes me suspect of foul intentions, akin to something we'd see from a KF a-log.
All in all, without sources, title of the book wrong and language, (not to mention the creator is refered to as "a canadian gentleman" so it's an anonymous source) I suspect it's fake news.
