In context, I interpreted pjeby to be saying that anecdotes counted as evidence which should lead a Bayesian rationalist to believe the truth of PUA claims. If that was not their intention I got them totally wrong.
However if I interpreted them correctly they were indeed applying Bayes incorrectly, since we should expect a base rate of PUA-affirming anecdotes even if PUA techniques are placebos, and even in the total absence of any real effects whatsoever. It’s not evidence until the rate of observation exceeds the base rate of false claims we should expect to hear in the absence of a non-placebo effect, and if you don’t know what the base rate is you don’t have enough information to carry out a Bayesian update. You can’t update without P(B).
