It isn't only about the degree of wrongness, but its type:
1. Vacuous, which provide no useful insight beyond what is obviously deducible. Such as "nearsightedness is caused by the wrong shape of the eye".
2. Vanity, which provide useless elaboration of something that is very well understood in a much simpler form, with no realistic hope of any future insight. Such as most of linguistics.
3. Pointless. Explain something that is difficult to get to know,
because it matters so little. While technically correct, the actual facts matter so little that they result in no realistic improvement of any kind, and no decisions are changed as the result of the new knowledge. Such as the age of Earth.
4. Theoretically wrong, those that the article is talking about. Even though theoretically wrong, the are so nearly equivalent to the actual truth, that the difference doesn't matter in practice.
5. Practically wrong. Those that "sound good" so that people stick to them, in spite of massive evidence to the contrary. Such as that obesity is caused by overeating, in spite of the near universal failure in practice, in the last instance of Ozempic making people look like walking corpses, rather than anything like a healthy body. This is the kind of errors meant by those who write to people like Asimov.
