Really depends on the subject.
I would say that 80% of men I know are more clever than me at understanding sports, driving cars, pleasuring themselves, picking the right beer, and using tools. I have very little knowledge of those areas.
Conversely, I would say that only 15% of the people I know are more clever than me when it comes to Computers and JRPGs. Only about 10% of the people I meet have a better command of grammar and punctuation than I do.
About 40% of people seem to have better social skills, which are at least partly learned. It is arguable that they're more clever than me in this way.
I don't know the percentage on this one, but a lot of people took a foreign language all four years in High School. They probably know more languages than me, and are thus more clever than me at speaking French, Spanish, or Chinese. While I am more clever than them at reading Latin, because that's the only other language I've seriously tried to learn. LOL.
You get the point though, right? Most people are only intelligent in a few areas, and are average or below average in the areas that don't interest them.
