Yes but ... knowing the answer to general knowledge questions isn't really an appropriate test of that. General knowledge sounds like it would be, by definition, things known to people of ordinary intelligence. So it could easily be that very intelligent people aren't up to speed about general knowledge topics because they spend their time on topics of interest to people of high intelligence. That is actually something of a trope.

The nature of the questions and why they are expected to know the answers matters a lot here.
