The earth revolving around the sun was also armchair reasoning, and refuted by empirical data like the lack of observable parallax of stars. Geocentrism is a pretty interesting historical example because of this: the Greeks reached the wrong conclusion with right arguments. Another example in the opposite direction: the Atomists were right about matter basically being divided up into very tiny discrete units moving in a void, but could you really say any of their armchair arguments about that were right?

Atoms can actually be divided into parts, so it's not clear that the atomists where right. If you would tell some atomist about quantum states, I would doubt that they would find that to be a valid example of what they mean with "atom".

The atomists were more right than the alternatives: the world is not made of continuously divisible bone substances, which are bone no matter how finely you divide them, nor is it continuous mixtures of fire or water or apeiron.

You could say the same of Dalton.
