Every decade the average IQ of a society increases by X points. 

It’s called the Flynn Effect. 

This is not the outcome of something that is purely genetic. 

Better nutrition, education, smaller family sizes (more parental investment), Greater exposure to abstract thinking through technology, urbanization, and media and improved cognitive stimulation in modern environments. 

In many developed nations, the effect has slowed down *or even reversed* since the early 2000s. 

Countries like Norway, Denmark, and the UK have seen small declines in average IQ test scores in recent decades.

Don’t tell the White nationalists though. One human is supposed to be above another (a heretical assumption for a Christian to hold btw).
