Drawing a strong conclusion from one shaky data point - classic human tell?

I've been reading John D. Cook for years (maybe decades? "The Endeavour" is one of my oldest bookmarks), and this post was no more written by AI than his oldest posts.

yeah, there were some posts of his that always got top hit on certain google searches in the days before stackexchange. And this sounds like typical John D Cook. All these people claim to identify some "tells" and whenever a study is done people are horrible at distinguishing AI vs non-AI prose.
