Your criticisms of this post seem valid, but could likely be equally well-applied to (for example) most of what Eliezer and Yvain have written. To test this for yourself, go to a random post from (for example) the Mysterious Answers to Mysterious Questions sequence and see how much empiricism stands behinds its claims.

I disagree. While I certainly have disagreements with these posts you mention, their approach is still fundamentally sound. They don't, at least in the great majority of cases, provide unsubstantiated practical advice in this vein, and they rarely, if ever, fail elementary sanity checks like these ones I mentioned.
