Captions available
The idea
The Flynn effect is the substantial rise in average intelligence test scores across the twentieth century in many countries.
In practice
Tests are periodically recalibrated to hold the average at one hundred, and the Flynn effect was noticed through those recalibrations.
Where people slip
Gains this fast cannot be genetic. Whatever the tests capture is strongly affected by environment.
