Asians in higher developed countries have higher IQ's than their counterparts The same go for blacks A few Asian countries have a culture that places a lot of respect on intelligence and they have a higher IQ than cultures that place a higher emphasis on hard work like the more rural focused countries. This is why it is theorized as for the reason Jews have the highest IQ's as there is evidence for this exact culture shift. Another example is the lower IQ's of whites who live in poor Eastern European countries. And the lower IQ's of the impoverished whites of the south(i.e. Rednecks for short) Then you take in the fact that IQ's have steadily rose in relation with technological advances and spreading of wealth over the years. As for technological advances of the past, European and middle Eastern people saw the fastest rise in technology and IQ among all other groups. They were still exceptions like the Gauls who remained stuck in time for years and were on the same level as the tribes of Africa and Asian Mongols. Anyway a similarity the Europeans and middle easterners shared was their region of development, which were both the most hostile to the human frame. Really pays homage to the phrase hottest fires make sharpest steel. So it is theorized that due to that they had to adapt faster than other groups, in a sense giving them an early start to the race, but as man has evolved to tame their environment towards their needs the other groups have steadily caught up and trends have shown that if the same conditions are placed over a long amount of time, IQ's range start to plateau.
