It is arrogance though. For example, let's say you're smarter than someone who has authority over you, i.e. their social status is higher than yours. In that case it wouldn't be smart to make that person feel inferior. Since if you were truly smart you'd think of a way to be right in a way that makes people like you.
I mean I’m autistic and on intelligence testing I’m all over the map. How smart I am depends on what you’re talking about. Just because I’m both more able and more trained to understand something than some senior manager, and I’m bad at the politics, doesn’t secretly unveil I’m not TRULY smart. In fact if we go back to OPs actual point, it was over people taking offence to his great confidence in specific subdomains of technology, something I have seen autistic people understand to a level of genius more than once.
