Where’s Brendon?

New Scientist reckons that all quantum mysteries disappear when you look at it as a Bayesian:

Living in wedded bliss, apparently.

He must be a good person.

I think Brendon suspected as much himself.

If we all think Bayesian thoughts really hard, he’ll probably drop in.

The “origin” and “background” sections of this read more like religious doctrine than hard physics.

The introduction reads like a bad joke (eg. don’t try reading Caves-Fuchs-Shacks out loud, “QBism” a pun on “cubism”).

I won’t take this seriously until I read the equations. The description sounds like a form of “hidden variable” theory, probabilities we can see depend on hidden probabilities that we can’t see. Hidden variable interpretations of of quantum mechanics are rejected by Bell’s theorem, so you’d have to look at in detail to see if this new interpretation has somehow dodged the bullet.

I don’t think you should bother with the New scientist article then :)

(But it seems their names do just happen to be Caves, Fuchs and Shacks)
