IQ has nothing to do with violence. A boy will become violent when he becomes effeminate.

It does not take higher IQ skills to follow basic moral structure.

The mass majority of the worlds population will not have need to use higher abstract thinking. Unless you are an engineer or scientist. Basically being in a field that needs it.

When is comes to putting together an organized society.

That becomes communication and people management skills. In fact… when working with groups of people. The communication needs to be simple. So most can understand what you are talking about.

When it comes to African IQ. I disagree with you.

I see your point. But just because Africans have not invented more automation type of products. Doesn’t mean they are not capable of doing so.

One of the biggest things about culture is prioritizing what is important.

Asians tend to prioritize things like math and science over other cultures. So they are good at it. Because time is spent their.

That’s doesn’t mean other groups are not capable. Other groups are just less interested.

When you take a test like an IQ test. Focus and concentration is needed to answer the questions.

If math is something not culturally important. A young person would most likely be inclined to space out and not care to focus on the test.

In fact.. that’s how I was in school. I hated test and spaced out during most of them.

I did better after I got out of college.

Where I disagree with you. You are assuming that just because a group of people don’t excel in XYZ area. That they are hopelessly handicapped in that area.

I see the brain as a muscle. You have to make effort to use it. To gain more intelligence.
