It's simply that hot countries grow food and have animals running around whole year, meaning you can live on daily basis with no regard for the future. Those who adapted to northern climates with actual seasons involving winter and snow, when there is barely anything to eat, had to develop actual abstract thinking, because idea of future and simulating yourself in the future based on observable factors is nothing but just abstract thinking. Coincidentally, ideas of promise, math and importance of laws, you know, things our civilization is founded on, are also strongly tied to abstract thinking. When you take IQ tests, they measure your ability to rotate and transform shapes in search of patterns, basically measuring efficiency of your abstract thinking. And since amount of melaning in skin is also tied to amount of sun through the year, you get corelation by proxy between IQ and skin color.
It's millenia of environment adaptation. Those who didn't have to develop abstract thinking to survive did not waste energy on it. Those who survived in the north had to develop it to survive. Turns out it produced superior outcome. Now question is where is the optimal point when it comes to socialization and altruism, because having too much of it creates breeding grounds for being exploited by scammers like pajeets and other trash which comes here for welfare and doesn't give a shit about laws and customs. Current state of affairs isn't sustainable and unless it changes, it will be yet another dead end of evolution.
