Galton designed it to illustrate his idea of regression to the mean,[2] which he called “reversion to mediocrity” and made part of his eugenist ideology.[3]

It piles up in a distribution curve. If you add more levels for the balls to bounce through, the curve will flatten. If you remove levels it will form a higher peak.
What’s ironic is In population genetics, distribution curves are useful in describing allelic frequency in a population. They are used to describe how allelic frequencies shift under selection pressure. It ultimately can be used to explain why a wider genetic diversity is superior to a narrow genetic diversity.
Distribution curves were used to prove eugenics wrong.
