Also that's not even getting in to the much much more complicated areas on "intellegence" and if there really is any difference between people and inate intellgence.
For example. Take a kid with an attention deficit disorder. (A real one... not like the majority of kids.)
Give him a pill... and suddenly he can concentrate better. His knowledge gaining skills rapidly increase.
The same could be said for anyone who doesn't cocentrate fully... learn to concentrate better or take stuff to concentrate better and your "intellegence" rises. Or at least how you define intellegence as how well you absorb knowledge.
There is little evidence to claim intellegence one way or another.
When it comes to Wisdom. Well wisdom is mostly a social construct...
When it comes to knowledge. "Stupid" people actually contain a lot of knowledge about various things. It's just in various things we deem unimportant.
