Answered on Quora.
Assuming you are in a town with mostly White people, a 100 IQ will resemble the IQ of 50% of the people you see out and about in your town every day. The other 50% will be tending towards the lower IQ or the higher IQ side. Most of these people will seem to be not extremely smart but not dumb at all by any means.
If you live in a mostly Hispanic, Black or Asian town, these results are going to be quite different.
Race Average IQ Asian 105 White 100 Hispanic 90 Black 85
