Today’s Word is: Heritability
[H]eritability captures the role that genetic differences play in making some people (relative to others) taller or shorter, heavier or lighter, more intelligent or less intelligent, so on and so forth. Virtually every measurable trait (which varies within the population), we now know, is heritable. This reality has become remarkably unimpressive to many behavioral geneticists, though it continues to blindside some scientists who have managed not to pay attention for the last several decades.
