Inheritability of a trait can be inferred through statistic means, though I feel like there is too much confidence around such computations, given that it is virtually impossible to isolate environment from genetics in Humans. But when looking for specific mutations, the sum of all these effects is often just a small fraction of that inheritability, suggesting that the interaction of the genes and the environment is more complex than can be captured with such models.
