Race Differences in Intelligence: An Evolutionary Analysis by Richard Lynn

Richard Lynn, one of the leading researchers on intelligence and personality and the author of several major books on IQ and personality research, summarizes in this landmark work what one scholar has described as “the definitive study of race differences in intelligence.” Since 1977, Richard Lynn has blazed a pioneering trail of research on racial differences in IQ. In previous books and scientific articles, Lynn has explored dysgenic trends in intelligence, sex differences in IQ, psychopathic personality traits, and the dimensions of personality and national character. In this book, Lynn analyzes the results of over 500 published studies that span ten population groups—races and sub-races worldwide—in what is certain to be a path-breaking book for IQ experts and educated laypersons alike. This comprehensive review of worldwide racial differences of general intelligence explores the formation of races, meaning of intelligence, validity of race differences in IQ, environmental and genetic correlates of intelligence, the relationship between brain size and intelligence, the evolution of racial differences in intelligence, and the factor of racial hybrids. In a relentlessly methodical approach, Lynn expands upon an extensive array of research findings from the biomedical and social sciences, including the latest studies from the fields of behavior genetics, evolutionary psychology, and anthropology in reaching his thought-provoking conclusions. Extensively referenced, this exhaustive study of race and IQ is a milestone accomplishment and should serve as the yardstick by which future research is measured. The IQs of the races…can be explained as having arisen from the different environments in which they evolved, and in particular from the ice ages in the northern hemisphere exerting selection pressures for greater intelligence for survival during cold winters; and in addition from the appearance of mutations for higher intelligence appearing in the races with the larger populations and under the greatest cold stress. The IQ differences between the races explain the differences in achievement in making the Neolithic transition from hunter-gathering to settled agriculture, the building of early civilizations, and the development of mature civilizations during the last two thousand years. The position of environmentalists that over the course of some 100,000 years peoples separated by geographical barriers in different parts of the world evolved into ten different races with pronounced genetic differences in morphology, blood groups, and the incidence of genetic diseases, and yet have identical genotypes for intelligence, is so improbable that those who advance it must either be totally ignorant of the basic principles of evolutionary biology or else have a political agenda to deny the importance of race. Or both. From Race Differences in Intelligence An Evolutionary Analysis Richard Lynn

The Growing Correlation Between Race and SAT Scores: New Findings From California

The connection between race and intelligence has been a subject of debate in both popular science and academic research since the inception of IQ testing in the early 20th century.

The unwelcome revival of ‘race science’

In a new documentary set to air on PBS this week, James Watson makes it clear that his views on the relationship between race and intelligence have not changed , reports the New York Times. He later apologized, and has suggested both that he was being a provocateur and that he didn't realize the comments were on the record. I would like for them to have changed, that there be new knowledge that says that your nurture is much more important than nature. But I haven't seen any knowledge. And there's a difference on the average between blacks and whites on I. I would say the difference is, it's genetic. Watson adds that he takes no pleasure in the difference between the races, the Times reports.

Take it from someone who did.

Evolutionary Psychological Science. It is often asserted that, when it comes to taboo topics like race, genes and IQ, scholars should be held to higher evidentiary standards or even censored entirely because of the harm that might result if their findings became widely known. There is held to be an asymmetry whereby the societal costs of discussing certain topics inevitably outweigh any benefits from doing so. This paper argues that no such asymmetry has been empirically demonstrated, and that stifling debate around taboo topics can itself do active harm. To suppress free speech is a double wrong. It violates the rights of the hearer as well as those of the speaker.

Its defenders claim to be standing up for uncomfortable truths, but race science is still as bogus as ever. By Gavin Evans. Fri 2 Mar The idea that certain races are inherently more intelligent than others is being trumpeted by a small group of anthropologists, IQ researchers, psychologists and pundits who portray themselves as noble dissidents, standing up for inconvenient facts. Through a surprising mix of fringe and mainstream media sources, these ideas are reaching a new audience, which regards them as proof of the superiority of certain races. Race scientists claim there are evolutionary bases for disparities in social outcomes — such as life expectancy, educational attainment, wealth, and incarceration rates — between racial groups. In particular, many of them argue that black people fare worse than white people because they tend to be less naturally intelligent.

The history of the race and intelligence controversy concerns the historical development of a debate, concerning possible explanations of group differences encountered in the study of race and intelligence. Since the beginning of IQ testing around the time of World War I there have been observed differences between average scores of different population groups, but there has been no agreement about whether this is mainly due to environmental and cultural factors, or mainly due to some genetic factor, or even if the dichotomy between environmental and genetic factors is the most effectual approach to the debate. In the late 19th and early 20th century, group differences in intelligence were assumed to be due to race; [1] apart from intelligence tests, research relied on measurements such as brain size or reaction times. By the mids most psychologists had adopted the view that environmental and cultural factors predominated. In the mids, physicist William Shockley sparked controversy by claiming there might be genetic reasons that black people in the United States tended to score lower on IQ tests than white people.

    I first encountered the question of race and intelligence sixty-eight years . racial IQs have been largely confirmed by the numerous studies that.
