A lot of interesting ideas there, but I think one of the main thrusts of the article is poorly substantiated.<p>The author discusses an "interference term" as being a characteristic of quantum mechanics (which is not exactly right, but nevermind), and then proceeds to describe this so-called "Hilbert-space search" as a natural consequence of that. But actually, the "Hilbert-space search" is just a search algorithm with a bit of semantic fuzzing. There's nothing "quantum mechanical" about it...<p>A bit of a shame that an otherwise enjoyable and interesting article was spoiled by a poor central argument, but there is nothing in there that directly links quantum mechanics to psychology, other than "ooh, it's weird and unintuitive".
