I think this is one of those language barrier things. Non-mathematicians sometimes say ‘obvious’ when what they mean is ‘vaguely plausible’.

- Timwi 1y agoA math professor at my uni said that a statement in mathematics is “obvious” if and only if a proof springs directly to mind. If that is indeed the standard, then it's easy to see how something that is vaguely plausible to an outsider can be obvious to someone fully immersed in the field.
- steve_gh 1y agoNot quite 'obviously', but mathematical folklore has it that 'clearly' is used to mark the difficult conceptual step in a proof.
