Aw man, this is a real bummer. I thought I'd weaned myself off of Gladwell, but his fabulism is embedded in my memories from way back :( he's so good at it!
The real L, as they say on Twitter now, is that we went so far on making scientific knowledge the only valid kind of knowing that fabulists must now come disguised as science (whereas in the past we all knew what Blavatsky, Gurdjieff, von Daniken etc were all about and could enjoy them for what they were).
