Data Sources & Notes

All 42 country estimates were refreshed on 2026-09-10 against the latest published Worlddata.info national IQ table (last modified September 2026; evaluation window 2007–2025), which synthesises the Rindermann (2007), Lynn & Meisenberg (2010) and Lynn & Becker (2019) datasets with PISA results from 2015–2025. The 2026 revision raised most European values by 2–6 points relative to the Lynn/Becker 2019 figures used in the previous version of this report (e.g., Estonia 100→106, Czechia 98→102, Spain 94→101, United Kingdom 100→105), consistent with re-normalisation against recent PISA rounds. Figures are shown as published (integers).

Primary IQ estimates: Worlddata.info, "IQ: Intelligence by country" (September 2026 update), based on Heiner Rindermann (2007), Khaleefa & Lynn (2008), Lynn & Meisenberg (2010), Lynn & Becker (2019) "The Intelligence of Nations" (Ulster Institute), and OECD PISA 2015–2025.

Palette: RG diverging palette (OKLCH perceptual color space) from the author's Palettes.json — Red oklch(0.50, 0.20, 25°) → Cream #FDF6E3 → Green oklch(0.50, 0.20, 143°); range clamped to the data bounds 87–106.

National IQ estimates are controversial and methodologically debated; a 2026 OSF evaluation (Sear, R., "'National IQ' datasets do not provide accurate, unbiased or comparable measures of cognitive ability worldwide") argues the underlying Lynn-style samples are often unrepresentative. Values represent broad averages from psychometric studies and PISA-derived proxies, and are influenced by education access, nutrition, socioeconomic factors, sampling methodology and the Flynn effect (plus a documented reverse-Flynn effect in several European countries). Interpret with caution.
