Simple thought experiment for why IQ matters more than you might think: It multiplies.

Lets say that, in an all-black country, the median car mechanic makes 3x more mistakes than the median car mechanic in an all white country.

Not good, but functional. You can get by fine with 3x as many car mechanic errors.

But you also have black drivers. Lets say black drivers are 3x as likely, over a given time frame for any given make and model, to mess up their car. Okay, now you have 3x as many cars needing fixing, so your mechanic errors and return trips to re-fix the problem is 9x.

We'll pass on the idea of all-black countries making their own cars.

Now, add to this, in all black-countries, you tend to get lower-end, older cars which start to have problems. Lets say these are 3x more likely to have problems, for a given level of maintenance.

So where are we? The cars are inherently 3x more likely to have some issue, the drivers are 3x more likely to mess something up, and the mechanics are 3x more likely to botch the repair. So 27x as many botched car repair jobs.

Everything is like this, to some degree. There's no one point that you can look at and go "aha, this is where they're messing up!", because it multiplies on itself.

This is why people who try to do things in Africa go "why does nothing ever work?".

In high school, going from a school in the midwest, to California, it was shocking. Gates around the school, guards, hall passes for when you wanted to take a leak. Hall passes in high school!

It's hard to describe. Just a seething web of difficulty. A more confrontational attitude between "students" and "teachers".

Obviously I'm opposed to the very idea of "high school", but when people are less intelligent and less reasonable, everything's just harder. It's like sand, it gets into everything.

Take wrestling. Brown coach. Thus, more likely to do dumb things like try to enforce "water discipline", get wrestlers to "adapt" to working with less water. Lock the doors to prevent wrestlers from leaving.

Brown wrestlers. Wrestling is a combative sport, sometimes you get elbowed in the nose, and they're more likely snap and start going berzerk in the middle of practice. Weight training management is more stupid and dangerous. More of them fail to make weight, and have to take drastic measures the day before the match.

The diversity gets everywhere. It's not some evil thing, it's mostly just stupid, and the stupidity makes everything harder.
