I mean, I agree with the sentiment of your original tweet, but what about nutrition and access? Can that help in the short-term? What about mixing ethnic groups?

It's more than IQ that will keep these countries from evolving to be like the west. Conflict, tribalism, etc. I think there are certain benefits to a "tribalistic" mindset, but there's inherently more harms when you're talking about 3rd worlders maintaining that mindset.

To be fair, hundreds of years may be well enough. At least the European Jews seem to have evolved their extremely high IQ over a remarkably short period of time, due to them not being allowed in traditional, manual labour professions.

Of course that kind of external pressure was a high price to pay and many died miserably when they couldn’t support themselves. So it’s not a system any people would inflict upon itself willingly.

LOL, technically it can change ... it can always go lower. Drugs, environment, accidents, and illness can all lower it. Never heard of it going up though.

South Korean women are 8" taller than 100 years ago. You would be right based on the assumptions of natural selection but adaptation is not the same as natural selection and is far more powerful. Maximum genetic expression in response to environment.

You simplify it so much that a distorted impression of it is given. Just as an example, the Ashkenazi jews had a slightly different way to their high IQ. All of the Ashkenazi Jews alive today can trace their roots to a group of about 330 people who lived 600 to 800 years ago..

.. They took over the banking industry in Europe (after the Knights Templars were outlawed), and the successfull -high IQ- members of this group, intermarried with other successfull families. (Getting to be successfull in banking, meant good or great mathemathic skills, which..

.. almost exclusively means high cognitive skills). Not only could they afford more children, more of their children survived; not only because they could afford better housing, food, heat and care; but they could afford proper silverware (made of silver), that coincidentally..

..had the lucky effect of killing germs/bacteria.. But YES, Europeans and North East Asians got their high IQ due to evolution and adverse living conditions..
