Arthur Robert Jensen was an American psychologist and writer. He was a professor of educational psychology at the University of California, Berkeley. Jensen was known for his work in psychometrics and differential psychology, the study of how and why individuals differ behaviorally from one another.
The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century, named after researcher James Flynn (1934–2020). When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100 and their standard deviation is set to 15 or 16 IQ points. When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first; the average result is set to 100. When the new test subjects take the older tests, in almost every case their average scores are significantly above 100.
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score. For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2 percent each above 130 and below 70.
Discussions of race and intelligence – specifically regarding claims of differences in intelligence along racial lines – have appeared in both popular science and academic research since the modern concept of race was first introduced. With the inception of IQ testing in the early 20th century, differences in average test performance between racial groups have been observed, though these differences have fluctuated and in many cases steadily decreased over time. Complicating the issue, modern science has concluded that race is a socially constructed phenomenon rather than a biological reality, and there exist various conflicting definitions of intelligence. In particular, the validity of IQ testing as a metric for human intelligence is disputed. Today, the scientific consensus is that genetics does not explain differences in IQ test performance between groups, and that observed differences are environmental in origin.
The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by the psychologist Richard J. Herrnstein and the political scientist Charles Murray in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance, birth out of wedlock, and involvement in crime than are an individual's parental socioeconomic status. They also argue that those with high intelligence, the "cognitive elite", are becoming separated from those of average and below-average intelligence, and that this separation is a source of social division within the United States.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason. Human intelligence is also thought to encompass their capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate.
The g factor is a construct developed in psychometric investigations of cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores based on many tests are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. However, the g factor itself is a mathematical construct indicating the level of observed correlation between cognitive tasks. The measured value of this construct depends on the cognitive tasks that are used, and little is known about the underlying causes of the observed correlations.
The Pioneer Fund is an American non-profit foundation established in 1937 "to advance the scientific study of heredity and human differences". The organization has been described as racist and white supremacist in nature. The Southern Poverty Law Center classifies the Pioneer Fund as a hate group. One of its first projects was to fund the distribution in US churches and schools of Erbkrank, a Nazi propaganda film about eugenics.
Richard Lynn was a controversial English psychologist and self-described "scientific racist" who advocated for a genetic relationship between race and intelligence. He was the editor-in-chief of Mankind Quarterly, a white supremacist journal. He was lecturer in psychology at the University of Exeter and professor of psychology at the Economic and Social Research Institute, Dublin, and at the University of Ulster at Coleraine. Lynn was a professor emeritus of psychology at Ulster University, but had the title withdrawn by the university in 2018.
Spearman's hypothesis has two formulations. The original formulation was that the magnitudes of the black-white differences on tests of cognitive ability positively correlate with the tests' g-loading. The subsequent formulation was that the magnitude of the black-white difference on tests of cognitive ability is entirely or mainly a function of the extent to which a test measures general mental ability, or g.
Helmuth Sørensen Nyborg is a Danish psychologist, writer, far-right politician and former Olympic canoeist. He is a former professor of developmental psychology at Aarhus University. His main research topic is the connection between hormones and intelligence. Among other things, he has worked on increasing the intelligence of girls with Turner's syndrome by giving them estrogen. He has also stood as a candidate for the far-right party Stram Kurs. His publications have been described as scientific racism.
The relationship between fertility and intelligence has been investigated in many demographic studies. There is evidence that, on a population level, measures of intelligence such as educational attainment and literacy are negatively correlated with fertility rate in some contexts.
The history of the race and intelligence controversy concerns the historical development of a debate about 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 the average scores of different population groups, and there have been debates over whether this is mainly due to environmental and cultural factors, or mainly due to some as yet undiscovered genetic factor, or whether such a dichotomy between environmental and genetic factors is the appropriate framing of the debate. Today, the scientific consensus is that genetics does not explain differences in IQ test performance between racial groups.
Heiner Rindermann is a controversial German psychologist and educational researcher.
Gerhard Meisenberg is a German biochemist. As of 2018, he was a professor of physiology and biochemistry at Ross University School of Medicine in Dominica. He is a director, with Richard Lynn, of the Pioneer Fund, which has been described as a hate group by the Southern Poverty Law Center. He was, until 2018 or 2019, the editor-in-chief of Mankind Quarterly, which is commonly described as a white supremacist journal and purveyor of scientific racism.
Aurelio José Figueredo is an American evolutionary psychologist. He is a professor of psychology, Family Studies and Human Development at the University of Arizona, where he is also the director of the Ethology and Evolutionary Psychology Laboratory. He is also a member of the interdisciplinary Center for Insect Science at the University of Arizona. His major areas of research interest are the evolutionary psychology and behavioral development of life history strategy, cognition, sex, and violence in human and nonhuman animals, and the quantitative ethology and social development of insects, birds, and primates. He is known for his research on personality, such as a 1997 study in which he and James E. King developed the Chimpanzee Personality Questionnaire to measure the Big Five personality traits in chimpanzees.
The London Conference on Intelligence (LCI) is an invitation-only conference for research on human intelligence, including race and intelligence and eugenics. In 2018, Times Higher Education called it "an annual conference on eugenics and intelligence" and several news outlets have described the conference as having ties to white supremacy, neo-Nazism, and scientific racism.
Noah Carl is a British sociologist and intelligence researcher who co-owns the Daily Sceptic blog. He was investigated and subsequently dismissed from his position as a Toby Jackman Newton Trust Research Fellow at St Edmund's College, Cambridge after over 500 academics signed a letter repudiating his research and public stance on race and intelligence, calling it "ethically suspect and methodologically flawed", and stating their concern that "racist pseudoscience is being legitimised through association with the University of Cambridge." An investigation by the college concluded that Carl's work was "poor scholarship" which violated standards of academic integrity, and that Carl had collaborated with right-wing extremists.
OpenPsych is an online collection of three pseudoscientific open access journals covering behavioral genetics, psychology, and quantitative research in sociology. Many articles on OpenPsych promote scientific racism, and the site has been described as a "pseudoscience factory-farm". The journals were started in 2014 by a pair of nonprofessional researchers, Emil Kirkegaard and Davide Piffer, who had difficulty publishing their studies in mainstream peer-reviewed scientific journals. The website describes its contents as open peer reviewed journals, but the qualifications and neutrality of its reviewers and quality of reviews have been disputed.
Ashkenazi Jewish intelligence, often colloquially referred to as "Jewish genius", is the stereotype that Ashkenazi Jews tend to have a higher intelligence than other ethnic groups.

In addition to the usual professional publications, the psychologist also publishes in controversial publications such as Mankind Quarterly – described by the American human rights organization Southern Poverty Law Center as 'the racist pseudo-scholarly Mankind Quarterly' – in which a comeback of eugenics is openly advocated. His papers have titles such as: “Why Do Northeast Asians Win So Few Nobel Prizes?”, “Does cultural background influence the intellectual performance of children from immigrant groups?”, “Group differences in mean intelligence for Dutch and third world immigrants”, “Spearman's hypothesis tested on European Jews vs non-Jewish Whites and vs Oriental Jews: Two meta-analyses”, “Solving the puzzle of why Finns have the highest IQ, but one of the lowest number of Nobel prizes in Europe”, “Spearman's hypothesis tested on Black adults: A meta-analysis”, “Spearman's hypothesis not supported? Three meta-analyses of Black and White prisoners, Northeast Asians, and Arabs and Jews”.
