I suppose we could also say IQ highly correlates with social ineptitude. Who could've known people wouldn't like you if you made repugnant statements... surely not 'smart' people!
Being socially ept requires high intelligence. However people that deeply apply their brains to social situations are often unrecognised as being bright in wider society. Although they may well be highly rewarded. And I suspect the very skilled often hide their skill because it's a hidden weapon in political or business negotiations. It is really hard to see applied IQ and you need to be very trusted for someone to explain their thinking: plus you need to be EQ smart to spot others that are EQ smart (and the +ve side of Dunning-Kruger causes problems too).
I think you are alluding to the stereotype of social ineptitude of geeks or academics. Personally I have found that focusing your IQ too tightly into one narrow discipline is not that smart. Really smart geeks seem to also be highly socially capable: IQ is general intelligence. Some of the smartest people I know left school at 15: you won't have highly academic discussions with them because it usually doesn't interest them but their raw IQ shows up in a bunch of other unobvious ways.
Disclaimer: I'm a geeky slow learner - a redundant disclaimer given I'm making comments on HN.
Edit: given we are on HN, here's a good example of Paul Graham deeply recognising someone as smart and socially epter than himself: https://www.paulgraham.com/jessica.html
