In this article, the authors argue that the overwhelming portion of the literature on intelligence, race, and genetics is based on folk taxonomies rather than scientific analysis. They suggest that because theorists of intelligence disagree as to what it is, any consideration of its relationships to other constructs must be tentative at best. They further argue that race is a social construction with no scientific definition. Thus, studies of the relationship between race and other constructs may serve social ends but cannot serve scientific ends. No gene has yet been conclusively linked to intelligence, so attempts to provide a compelling genetic link of race to intelligence are not feasible at this time. The authors also show that heritability, a behaviorgenetic concept, is inadequate in regard to providing such a link. (PsycINFO Database Record © 2016 APA, all rights reserved)

It is widely accepted that race differences in intelligence exist, but no consensus has emerged on whether these have any genetic basis. The present book is the first fully comprehensive review that has ever been made of the evidence on race differences in intelligence worldwide. It reviews these for ten races rather than the three major races (Africans, Caucasians, and East Asians) analyzed by Rushton (2000). The races analyzed here are the Europeans, sub-Saharan Africans, Bushmen, South Asians and North Africans, Southeast Asians, Australian Aborigines, Pacific Islanders, East Asians, Arctic Peoples, and Native American Indians. Studies of these are presented in Chapters 3 through 12; Chapter 13 summarizes these studies and gives evidence on the reliability and validity of the IQs of the races. Chapter 14 discusses the extent to which race differences in intelligence are determined by environmental and genetic factors. Chapters 15, 16, and 17 discuss how race differences in intelligence have evolved over the course of approximately the last 100,000 years. These discussions are preceded by accounts of the nature of intelligence and the measurement of race differences given in the first chapter, and of the concept of race in Chapter 2.

Some have argued that the cause of Black–White differences in IQ is a pseudoquestion because “race” and “IQ” are arbitrary social constructions (Tate &Audette, 2001).
You can talk about the genetics of race. You can talk about the genetics of intelligence. The genetics of race and the genetics of intelligence are two different fields of research.
Throw in the outside factors experience, education, training, social interaction, family, wealth, environment and measuring intelligence becomes blurred as to cause and effect.
Can you find anywhere in the world people of different races that have not been affected by the factors above to measure and compare intelligence?
