When we reject explanation B in favour of explanation A, there must be some property of the explanations that comprehensively distinguishes A as better than B.

That property is hard-to-vary-ness.

The more HTV an explanation is, the more closely it corresponds to reality.

The idea ‘I’m located in a hemisphere’ is ‘easy to vary’ as to which hemisphere but it’s true, meaning it corresponds to reality.

HTV and correspondence are orthogonal.

Take the same explanation in two possible realities. The explanation has the same content and the same HTV in both, but it can correspond to one reality and fail to correspond to the other. HTV alone therefore cannot determine correspondence.

There’s a risk in posting follow-up thoughts as nested comments. The risk is that criticism chains won’t bubble up far enough.

If you want to add more information to an idea, I suggest revising it.

They are separate ideas, and the latter ideas depend on their formers. If there is a flaw in former ideas, they apply to latter ideas, but if there is a flaw in latter ideas, they don’t necessarily apply to the former. So arranging them like this was intentional, to respect that hierarchy.
