Conjecture
An explanation is good when it is hard to vary: each of its details does work, so it cannot be adjusted to fit whatever is observed. Testing only discriminates among explanations that already meet that standard; an easily varied theory survives any refutation by swapping in a variant, so testing it decides nothing. Deutsch's case is the axis-tilt account of seasons against the Persephone myth.

It is only when a theory is a good explanation, hard to vary, that it even matters whether it is testable. Bad explanations are equally useless whether they are testable or not.
