It seems you suffer from some misconceptions while being aware of some moderately obscure truth.

First of all, good on yer that you know that IQ is normalized to 100. The problem is that this is true for some particular group of people. I’m not sure offhand what body does this normalization and what population they use, but thankfully, that knowledge doesn’t matter.

Any particular group of people will probably not have an average IQ of 100. Only the full body of people it’s normalized to will.

So if they normalize IQ to all USians, the average IQ in other countries will naturally be somewhat close to 100 (probably), but not precisely 100. So move people elsewhere and the average IQ of the destination country will change by some probably-relatively-small amount.

Or, if the entire world is normalized to 100, then the average IQ in NO countries is precisely 100, and moving people around will still change the average.

So I’m afraid you need to back up your clapbacks and take another think through on this, friend.

this county sucks.

You should broaden your horizons. :)
