What is the link between race and intelligence?
There is no scientific evidence to support a link between race and intelligence. Intelligence is a complex trait that is influenced by many factors, including genetics, environment, education, and culture. Race, on the other hand, is a social construct that is based on physical characteristics such as skin color, hair texture, and facial features. While there may be genetic differences between individuals of different races, these differences do not correspond to any meaningful differences in intelligence.

It is important to recognize that any attempts to link race and intelligence can have harmful and divisive effects on society. The notion that certain races are inherently more or less intelligent than others has been used throughout history to justify discrimination and oppression, and it has no scientific basis. It is essential to base our understanding of intelligence on rigorous scientific research, free from bias and prejudice, and to reject any attempts to use intelligence as a means of perpetuating discrimination or inequality.
The role of genetics in determining measured differences in mean IQ between putative racial groups has been a focus of intense discussion and disagreement for more than 50 years. While the last several decades of research have definitively demonstrated that genetic variation can influence measures of cognitive function, the inferences drawn by some participants in the controversy regarding the implications of these findings for racial differences in cognitive ability are highly dubious. Of equal importance, there is no compelling scientific rationale for focusing on and devoting substantial effort to determining mean differences in intelligence or other cognitive functions between groups with incompletely defined and dynamic (and therefore not definitively definable) boundaries.

This says pretty much what I said before. Links between race and intelligence was controversial a while back. The scientific community today however agrees that there are no links between race and intelligence. Sure, factors like diet, mental support, physical health, etc. during childhood may affect the development of cognitive functions. Studies that show a link between race and intelligence ignore this point. Such studies thus succumb to the causal fallacy, where they incorrectly conclude lower intelligence in certain parts of the world to be caused by race due to statistical correlations. In reality however, such areas face issues like poverty, malnutrition, war, etc. which lead to lower cognitive development during childhood.
