Race is Entirely a Social Construct

False Assumption: Race is a social construct with no genetic basis, and there are no socially important differences between human ancestry groups.

For much of the postwar era, educated opinion held that race was a social construct, not a biological fact. That view had serious reasons behind it. Earlier racial science had been crude, political, and often vicious, and scholars such as Ashley Montagu argued that the old racial categories were too inconsistent and too entangled with local custom to count as sound biology. W.E.B. Du Bois had made a similar point long before, and by the late twentieth century Richard Lewontin’s famous 1972 result, that most human genetic variation exists within populations rather than between them, gave the slogan a scientific backbone. Anthropologists and public health scholars then pushed the line that there are no discrete races in nature, only gradual clines, mixed ancestry, and social labels that change from country to country.

That case still has force. There are no absolute genetic boundaries that cleanly separate all humans into the familiar boxes, and categories like “Black,” “white,” or “Asian” are defined differently across societies. Race-based medicine has also misled doctors, sometimes badly, by treating broad labels as if they were precise biological guides. But since the early 2000s, growing evidence has complicated the stronger claim that race has no genetic basis at all, or that ancestry groups show no socially important biological differences. Studies of population structure, including work by Neil Risch and others and the 2002 Rosenberg paper, found that genetic data can often sort people into clusters that roughly track continental ancestry. Critics of Lewontin, most famously A.W.F. Edwards, argued that while variation within groups is large, correlations across many loci still make group structure detectable.

The current debate turns on what follows from that fact. A substantial mainstream still says ancestry is biologically real but race remains too blunt, too political, and too imprecise to do much scientific work. An influential minority of researchers argues that the old formula, “race is only a social construct,” has been stated too absolutely, because genetic ancestry does correlate with some medically and socially relevant traits. Others reply that these correlations do not rescue folk racial categories, and that the history of racial thinking is full of overreach dressed up as measurement. So the assumption has not vanished, but it is increasingly questioned in its strongest form.

People Involved
  • Ashley Montagu published Man’s Most Dangerous Myth: The Fallacy of Race in 1942 while working as an anthropologist. He argued that race was a social concept with no genetic basis. The book gained wide circulation among academics and policymakers who saw it as a scientific rebuttal to Nazi racial theories. Its influence persisted for decades in shaping how social scientists discussed human differences. [1]
  • Richard Lewontin was a geneticist at Harvard who published a 1972 study analyzing protein variation across populations. He showed that 85 percent of variation occurred within populations and only 15 percent across races. Lewontin concluded that most genetic variation existed between individuals rather than between groups. The paper became a standard citation for those who viewed racial categories as lacking biological meaning. [1][6]
  • Bryan Pesta was a tenured intelligence researcher at Cleveland State University. In 2019 he published a peer-reviewed study using NIH data that found genetic ancestry predicted cognitive ability. An anonymous complaint led to an investigation. The university fired him despite the study having passed peer review with no methodological errors identified. [8]
  • A.W.F. Edwards was a statistical geneticist at Cambridge. In 2003 he critiqued Lewontin’s focus on single loci by demonstrating that cluster analysis of correlated markers could distinguish races. His paper received limited attention at first. Later genomic work repeatedly confirmed the multivariate structure he described. [6][10][17]

Organizations Involved

The American Anthropological Association adopted its Statement on Race in 1998. The organization presented race as a dynamic folk concept rooted in phenotypic differences rather than biology. It launched the RACE public education project in 2007 which traveled to 41 cities over nearly a decade. The exhibition and accompanying materials taught that race was a cultural construct without biological basis. [4][5]

The American Association of Biological Anthropologists issued a statement in 2019 denying any biological basis for race. The executive committee adopted it unanimously and published it in the association’s journal. The document described race as a colonial social construct and committed members to eliminating racial concepts from research design and interpretation. [7]

Cleveland State University received an anonymous complaint about Pesta’s 2019 paper. Administrators opened an investigation that bypassed normal scientific channels. The university ultimately terminated his tenured position citing the sensitive nature of the research topic. The action sent a signal across academia about the risks of studying certain ancestry-related questions. [8]

Science published a 2016 article by several scholars calling for the phase-out of racial categories in genetics research. The journal gave prominent space to the argument that such categories were crude proxies for ancestry. It urged the National Academies to form a panel to guide the field away from race. The piece reflected the prevailing view in parts of the scientific press at the time. [2]

The Foundation

The assumption that race is a social construct with no genetic basis drew strength from inconsistent definitions across countries. In the United States any known African ancestry classified a person as Black while in Brazil the same person might not be. This variability seemed to show that racial categories could not reliably correlate with ancestry. It reinforced the view that race lacked a stable biological foundation. [1]

Lewontin’s 1972 analysis examined 17 genetic loci across seven populations. It found 85 percent of variation within populations, 8 percent among local populations within races, and 6 percent between continental races. The numbers appeared to prove that racial classification had no genetic significance. The result became a standard reference even though it averaged across unlinked loci. [3][6][17]

Subsequent studies using different methods produced contrasting pictures. The STRUCTURE algorithm identified five main genetic clusters corresponding to major geographic regions without any prior information about sample origins. Within-population differences still accounted for 93 to 95 percent of total variation but the clusters aligned closely with self-reported race. Only 0.14 percent of subjects showed genetic cluster membership different from their self-identified race or ethnicity. [9][13][14]

Edwards pointed out in 2003 that Lewontin’s approach overlooked correlations across loci. His critique used simple binomial examples to show that multiple markers with correlated frequencies allow near-perfect population discrimination despite high within-group variation. Later genomic studies repeatedly confirmed this multivariate structure. The debate remained active with growing evidence suggesting ancestry clusters carry predictive information. [10][17]

How It Spread

Lewontin’s 1972 conclusion spread quickly through scientific media. Outlets such as New Scientist and Nature repeated that individuals differ more than races do and that genetic variation is mostly within groups. The phrasing became a standard sound bite in interdisciplinary discussions. It was applied beyond genetics to dismiss race in biology and social policy. [17]

The American Anthropological Association’s 1998 statement and its RACE exhibition carried the social-construct view to broad audiences. The traveling show visited dozens of cities and left permanent exhibits in several museums. Its materials presented race as a historically situated cultural idea rather than a biological reality. The campaign helped embed the assumption in public education and academic training. [4][5]

The assumption gained further reach when key phrases from Lewontin’s paper appeared in documentaries such as Race: The Power of an Illusion. Popular summaries of genetics often cited the within-group variation figure as proof against any genetic basis for race. This framing shaped how many journalists and educators discussed human ancestry. Dissenting statistical arguments received less public attention for years. [6]

Moral pressure in academic settings reinforced the consensus. In left-leaning disciplines claims about biological group differences were often treated as implying inferiority. This atmosphere discouraged certain lines of inquiry. The pattern extended to related topics such as sex differences where similar dynamics played out. [15]

Resulting Policies

The American Anthropological Association’s 1998 Statement on Race declared that race was a folk concept rooted in phenotypic differences. It guided anthropological practice and public outreach for the following decades. The statement framed group inequalities as resulting solely from social, economic, and political circumstances rather than biological inheritance. Many anthropology departments adopted this framing in curricula and research priorities. [4][5]

The American Association of Biological Anthropologists committed its members to eliminating race concepts from study designs, data interpretation, and research reporting. The 2019 statement became a professional norm within the field. It described race as a colonial social invention and urged researchers to avoid racial categories. The policy influenced how grants were written and papers were reviewed. [7]

Cleveland State University terminated tenured professor Bryan Pesta after a complaint about his NIH-funded study on genetic ancestry and cognition. The action treated the research topic itself as grounds for sanction. No methodological flaws were found in the peer-reviewed paper. The case illustrated how institutional policies could enforce boundaries around certain questions. [8]

Connecticut public school athletic policies allowed transgender girls to compete in girls’ track events. Andraya Yearwood and another transgender athlete placed first and second in state championships. Officials cited claims that hormone suppression negated male advantages. Critics argued the policy overlooked correlated traits such as height, muscle mass, and skeletal structure. [16]

Harm Caused

Race-based medical assumptions contributed to underdiagnosis of cystic fibrosis in people of African ancestry. Physicians sometimes viewed the disease as primarily affecting white patients. This pattern delayed treatment for affected children and adults in non-European populations. The assumption that race lacked biological meaning complicated efforts to tailor medical predictions to ancestry. [2]

Bryan Pesta lost his tenured position at Cleveland State University after publishing peer-reviewed work on genetic ancestry and cognitive ability. The dismissal chilled similar research by other academics who feared comparable repercussions. It distorted research agendas by making certain topics professionally risky. The episode illustrated how enforcement of the assumption could affect careers. [8]

Larry Summers resigned as president of Harvard after speculating about biological factors in sex differences in science and engineering. The backlash included protests and sustained criticism. His departure reinforced norms against discussing biological hypotheses for group disparities. The controversy contributed to a broader climate that stunted certain lines of inquiry. [15]

Transgender girls displaced cisgender girls in Connecticut high school track championships. Yearwood finished second in one event and another transgender athlete took first in others. Critics documented measurable differences in performance that persisted despite hormone suppression. The policy and its outcomes became a flashpoint in debates over fairness in women’s sports. [16]

Downfall

Genome-wide association studies began identifying genetic risk factors for prostate cancer that are more common in West African ancestry. These variants helped account for higher rates among African Americans. The findings highlighted ancestry-related correlations that the social-construct view had downplayed. Medical researchers increasingly incorporated such data despite earlier cautions against racial categories. [1]

Noah Rosenberg’s 2002 study using the STRUCTURE algorithm on 1,056 markers confirmed five continental clusters. The work showed that self-reported race matched genetic clusters with high accuracy. These results quietly accumulated as growing evidence that challenged the earlier consensus. [6][9][14]

The complaint against Bryan Pesta collapsed when the accuser withdrew the claim of IRB violation. The study remained in the peer-reviewed literature with no methodological refutation. Data access was confirmed to have been granted properly. The episode exposed how institutional responses sometimes prioritized taboo avoidance over scientific critique. [8]

Critics such as Steven Pinker and Carole Hooven highlighted the role of social pressure in maintaining blank-slate assumptions about sex differences. Biologist Jerry Coyne explained that sex is bimodal with 98 to 99 percent of humans clearly male or female. Leonard Sax showed that true intersex conditions occur at roughly 0.018 percent rather than the 1.7 percent sometimes cited. These arguments gained traction outside the disciplines that had enforced the stricter view. [15][16]

“Our findings could fully account for the higher rate of prostate cancer in African-Americans than in European-Americans.”— How Genetics Is Changing Our Understanding of 'Race'
“A recent study led by the economist Daniel Benjamin compiled information on the number of years of education from more than 400,000 people... identified 74 genetic variations... One of these, led by the geneticist Danielle Posthuma, studied more than 70,000 people and found genetic variations in more than 20 genes that were predictive of performance on intelligence tests.”— How Genetics Is Changing Our Understanding of 'Race'
“"What the study of complete genomes from different parts of the world has shown is that even between Africa and Europe, for example, there is not a single absolute genetic difference, meaning no single variant where all Africans have one variant and all Europeans another one, even when recent migration is disregarded," Pääbo told Live Science.”— Race Is a Social Construct, Scientists Argue
“In the last five years there has been a revolution in our assessment of inherited variation, as a result of the application of molecular biological techniques to population problems. Chiefly by use of protein electrophoresis... it is the rule, rather than the exception, that there is genetic variation between individuals within populations.”— The Apportionment of Human Diversity
“Two analyses for man, one on enzymes by Harris (1970) and one on blood groups by Lewontin (1967), give respective estimates of 30% and 36% for polymorphic loci within populations, and 6% and 16% for heterozygosity per gene per individual.”— The Apportionment of Human Diversity
“the apparent critique by Edwards [10] in particular considers a different aspect of the taxonomy problem from the one Lewontin aimed for and does not invalidate the central insight provided by Lewontin's result.”— The background and legacy of Lewontin's apportionment of human genetic diversity

“Jerry Coyne... explains: ...if you do a plot of sex versus frequency... you’ll get a plot with two distinct and widely-separated peaks, with a valley containing some intermediates (intersexes and the like) between them. This is what I mean by the bimodality of sex. And there’s a reason for it: having two sexes is the result of evolution in our ancestors.”— Why So Many Progressives Are Arguing That Biological Sex Doesn't Exist
“In a 2002 response to the 2001 Anne Fausto-Sterling paper, Leonard Sax writes: ...the true prevalence of intersex is seen to be about 0.018%, almost 100 times lower than Fausto‐Sterling's estimate of 1.7%.”— Why So Many Progressives Are Arguing That Biological Sex Doesn't Exist
“With a difference between the means of 40 and a common standard deviation of less than 4.6, there is virtually no overlap between the distributions, and the probability of misclassification is infinitesimal... Very recent studies(14,15) have treated individuals ... thus revealing genetic affinities that have unsurprising geographic, linguistic and cultural parallels.”— Human genetic diversity: Lewontin’s fallacy
