Where the number comes from, and its limits

LifeScore shows a rounded estimate drawn from the national IQ compilations of Lynn & Vanhanen (2012) and Rindermann (2018). Both gather published test results for each country and convert them to a common scale. Researchers disagree about how far those figures can be trusted, for these reasons:

  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 77 for South Africa 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 South Africa, 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.
