Nope. As I said previously, some individuals are smart, some are dumb, some are in-between. My outright statement (not implication) is that it is not at all determined by what the color of their skin is or what country/continent/whatever they come from.
Indeed not all. But there should be some dependencies, based on world around certain population group. Like, in warm/tropic countries there might be less need in efforts of getting food. Based on that, different people groups might have different "intellectual" potential (or at least, that potential might be distributed differently vs other group)
again, in average.
Don't you agree?
Also, do you guys assume that it's kind of an RPG where you have base stats like STR, DEX, INT as 10 and you have 20 points to distribute? It's looking like creationism.
I think that it's totally might be that some group might have 16 and some 24 points to "distribute".
