Average IQ in Finland

The average IQ in Finland is estimated at 97 to 101. The most-cited national dataset (Lynn and Vanhanen, 2012) gives 97 from IQ test data and 100.9 once school results are included, on a UK-normed scale.

Where the figure comes from

Finland is a good example of why national IQ figures need care. Lynn and Vanhanen's IQ test data put Finland at 97, below the UK. Adding Finland's strong school results lifts the estimate to 100.9. Which number you quote depends on which evidence you trust.

Finnish psychologists use tests with Finnish or Nordic norms, on which the average is 100 by definition.

Finland in PISA 2025: what 15-year-olds can do

PISA tests 15-year-olds in maths, reading and science. Finland was once the top European performer, but its scores have fallen across several rounds. In PISA 2025 Finnish students were above the OECD average in maths, reading and science, though maths fell from 484 in 2022 to 469.

Adult skills: the OECD Survey of Adult Skills

The OECD Survey of Adult Skills tests adults aged 16 to 65. In the 2023 round Finland was at or near the top of all participating countries in literacy, numeracy and adaptive problem solving, well above England, Canada and the US.

Is the average IQ in Finland rising or falling?

Finland has some of the clearest evidence of falling test scores. Finnish military conscripts, almost all young men, take the same reasoning test on entry. Scores fell between 1997 and 2009, by about 2 IQ points a decade (Dutton and Lynn, 2013; Dutton and colleagues, 2016).

Similar falls appear in Norway and Denmark. A Norwegian study of brothers found that both the earlier rise and the later fall happened within families, which points to environmental causes such as schooling and media rather than changes in who has children (Bratsberg and Rogeberg, 2018).

Why national IQ figures are contested

  1. Different tests

    National figures combine different instruments, such as Raven's matrices, Wechsler scales and school assessments like PISA, taken in different years and converted to one scale. The 97 to 101 for Finland inherits every step of that conversion.

  2. Sampling

    Some national estimates rest on small or unrepresentative samples, such as one city, school or age group. Reviews such as Wicherts, Dolan and van der Maas (2010) found that sample choices can move a country figure by many points.

  3. Education and health

    Scores rise with years of schooling, nutrition, health care and familiarity with timed tests, so a national average partly measures those conditions rather than a fixed trait.

  4. The Flynn effect

    Raw scores on many tests rose by roughly 3 points a decade during the 20th century (Flynn, 1987), and some countries have since seen plateaus or declines. The year a sample was tested changes the number.

  5. Not about individuals or ethnicity

    The spread of scores inside Finland, as in any country, is far wider than the gap between countries. A national estimate says nothing about any person, and it is not evidence about ethnicity or genetics.

Average IQ in Finland: questions people ask

What is the average IQ in Finland?

97 to 101, depending on the evidence. Lynn and Vanhanen give 97 from IQ test data and 100.9 including school results. On Finnish test norms the average is 100 by definition.

Is Finland's IQ declining?

Conscript test scores fell between 1997 and 2009, by about 2 points a decade. PISA scores for 15-year-olds have also fallen across several rounds. Finnish adults still had some of the highest literacy and numeracy scores in the OECD's 2023 survey.

Why does Finland do so well in adult skills tests?

Researchers point to strong, equal schooling, high adult education rates and a reading culture. The survey measures literacy and numeracy, not IQ, so it reflects education as much as reasoning.

What is a good IQ score in Finland?

The same as anywhere. Modern IQ tests are scaled so the average is 100 and two in three people score between 85 and 115. A score of 115 is higher than about 84% of people, and 130 is the top 2%.

Can a country average tell me my IQ?

No. The spread of scores inside any country is far wider than the gaps between countries. The only way to know your own score is to take a test.
