Does anyone know of a blinded rank ordering of headphone quality by an expert? Headphone reviews read like wine reviews. I just want to know things like at what point the quality vs. price correlation becomes super weak, and you could easily determine that from a blind ranking.
Rereading that article, I noticed: "Proving a null hypothesis is akin to proving the halting problem; you can't." No, I can: suppose you had a program that solved the halting problem. Construct a program which calls that program and does the opposite of what it says. Fail!

Of course for "Fail!" you may substitute the usual things said at the end of a proof by contradiction. I kind of like "Fail!", though.

You can't prove a null hypothesis, but you can keep testing it. Humans function pretty well in a world of halting problems. Most of the time anyway.
