changing focus is not an option!

Here is a quote from Mervyn Stone’s discussion of the DIC paper in Series B

“The paper is rather economical with the ‘truth’. The truth of p^t(Y) corresponds fixedly to the conditions of the experimental or observational set-up that ensures independent future replication Y^rep or internal independence of y = (y₁,…,y_n) (not excluding an implicit concomitant x). For p^t(Y) ≈ p(Y|θ^t), θ^t must parameterize a scientifically plausible family of alternative distributions of Y under those conditions and is therefore a necessary ‘focus’ if the ‘good [true] model’ idea is to be invoked: think of tossing a bent coin. Changing focus is not an option.”

that I found most amusing (and relevant)! Elías Moreno and I wrote our discussions from Newcastle-upon-Tyne  for Series B (and arXived them as well, with a wee bit of confusion when I listed the affiliations: I am not [yet] associated with la Universidad de Las Palmas de Gran Canaria..!).
