Oblique request made without any explanation: can anyone provide examples of beliefs that are incontrovertibly incorrect, but which intelligent people will nonetheless arrive at quite reasonably through armchair-theorising?

I am trying to think up non-politicised, non-controversial examples, yet every one I come up with is a reliable flame-war magnet.

ETA: I am trying to reason about disputes where on the one hand you have an intelligent, thoughtful person who has very expertly reasoned themselves into a naive but understandable position p, and on the other hand, you have an individual who possesses a body of knowledge that makes a strong case for the naivety of p.

What kind of ps exist, and do they have common characteristics? All I can come up with are politically controversial ps, but I'm starting my search from a politically-controversial starting point. The motivating example for this line of reasoning is so controversial that I'm not touching it with a shitty-stick.

This isn't very interesting, but I used to believe that the rules about checkmate didn't really change the nature of chess. Some of the forbidden moves - moving into check, or failing to move out if possible - are always a mistake, so if you just played until someone captured the king, the game would only be different in cases where someone made an obvious mistake.

But if you can't move, the game ends in stalemate. So forbidding you to move into check means that some games end in draws, where capture-the-king would have a victor.

(This is still armchair theorising on my part.)
