Is race a social construct?

Many scholars in the humanities and parts of biology maintain that “race” is primarily a socio-historical system for classifying people that does not map cleanly onto human genetic diversity [4] [6] [9]. Others argue that the term can be rescued as a rough synonym for genetically recognisable continental‐scale population structure [1] [5] [7] [10] [11] [13]. Both sides agree that human variation is continuous and that political categories such as “Black” or “White” have changed over time; they disagree on whether the observed clustering justifies retaining the word “race”.

Arguments for race being a social construct

Historical fluidity: Groups once considered separate “races” (e.g., Irish, Italians in 19th-century America) later merged into a broader “White” category [4].
Intragroup genetic diversity: Lewontin (1972) showed that ~85 % of gene frequency variation lies within traditionally named races rather than between them, suggesting weak biological discreteness [6] [9].
Political origin: Colonialism, slavery and 20th-century eugenics invested race with legal and ideological power, making it a cultural rather than biological entity [4] [6].
Genomic clines: Modern sequencing demonstrates gradients, admixture and overlap rather than hard boundaries [6] [9].

Arguments against race being only a social construct

Cluster analyses: When thousands of ancestry-informative markers are used, unsupervised algorithms often recover clusters that correspond to continental ancestries [1] [5] [10] [11].
Medical relevance: AI systems can infer patient self-identified race from X-rays that look identical to human experts, implying latent, population-linked biological signals [2].
Predictive power: Knowing broad ancestry improves risk prediction for certain diseases (e.g., sickle-cell in West-African ancestry, cystic fibrosis in North-European ancestry) [5] [7] [11].
“Lewontin’s Fallacy”: Edwards (2003) showed that between-group allele frequency correlations allow reliable classification despite high within-group diversity [10].

Historical factors shaping the “race as social construct” view

UNESCO statements (1950, 1951, 1967) after WWII promoted the idea that race has “no biological foundation” to combat scientific racism [4].
Civil-rights era scholarship in the 1960s–70s emphasised environmental explanations for inequality, reinforcing the constructivist position [6].
Genomic findings in the 1970s (Lewontin) and the Human Genome Project in 2000 fuelled the claim that biology does not support discrete races [6] [9].
Social movements in the 2010s placed moral and political pressure on institutions; critics note a “conformity problem” where dissenting scientists fear reputational damage [3].

Human population groups and some known differences

Geneticists often speak of broad “continental ancestry groups” (Sub-Saharan African, European, East Asian, South Asian, Native American, Oceanian). Boundaries blur in regions of long-term admixture [5] [7] [11].

Documented average differences include [5] [7] [11]:

Allele frequencies: lactase persistence common in Northern Europeans; EDAR variant affecting hair thickness in East Asians; Duffy-null allele conferring malaria resistance in many Africans.
Disease risk: higher sickle-cell trait prevalence in West-African ancestry; Tay-Sachs founder mutations in Ashkenazi Jews; differing BRCA mutation spectra across groups.
Phenotypic traits: skin pigmentation gradients, average stature differences, craniofacial metrics.
Non-medical signals: AI detection of ancestry from medical imaging and even retinal scans [2].

Origins of different population groups

Shared origin: Anatomically modern humans left Africa ~50–70 kya.
Founder events: Small subsets populated Eurasia, Oceania and the Americas, accumulating drift and local adaptation [5] [11].
Admixture: Neanderthal introgression in all non-Africans; Denisovan components in Oceania and parts of Asia [5].
Recent migration: The last 500 years produced extensive gene flow (e.g., Atlantic slave trade, European colonisation) leading to highly admixed populations in the Americas [7] [11].

The race and IQ debate

Core claim: Average IQ test scores differ among continental ancestry groups, with both environmentalists and hereditarians disputing the causes [8] [12].
Hereditarian position: Part of the gap reflects genetic differences; supported by twin/adoption studies and polygenic score work, though the latter is still Euro-centric [1] [8] [13].
Environmental position: Gaps stem from socio-economic factors, test bias, and historical inequality [6].

Controversy timeline:

1969 Jensen’s “How much can we boost IQ?” sparks debate.
1994 “The Bell Curve” popularises hereditarian view.
2003–2010 Genomics enters the discussion; Lewontin vs. Edwards exchange influences framing [10].
2013 Jason Richwine resigns from Heritage Foundation after writing on IQ and immigration [12].
2017-present Internet outlets (Quillette, Aporia) revive hereditarian arguments [1] [8]; mainstream venues warn against over-interpretation of polygenic scores [6] [7].

Public discourse timeline (selected points)

1940s–50s UNESCO race statements emphasise social construction [4].
1972 Lewontin publishes genetic variance study [6].
2003 Edwards critiques Lewontin, coining “Lewontin’s Fallacy” [10].
2018 David Reich NYT op-ed argues for frank discussion of population genetics [7].
2020 Scholars highlight political pressures limiting dissent [3].
2022 AI paper shows race detection in medical images, reigniting debate on biological signals [2].

Conflicting views: The UNESCO tradition (constructivist) [4] and some genomic scholars [6] argue race is not biologically real, whereas race-realist writers [1] [5] [10] claim observable genetic structure justifies the term. Moderate positions (e.g., Reich) accept population differences but caution against reifying folk categories [5] [7].
