Nature Doesn't Care About Fair

Writing at Bloomberg View, Megan McArdle asks a non-PC question: "Why can't members of the sexes be more alike? Why do so many irritating differences persist?" One of her responses was the following, which resonates with me:

When evaluating scientific findings, I always remind myself: "The universe is not here to please you" and "nature doesn't care about fair." It can be true that women are less likely to have astounding math or engineering abilities, even though that's unfair as heck, and I don't like it. In the world of science, things do not become more true just because we'd be better off if they were.

And when it comes to gender, it's clear that nature is completely uninterested in fairness. All nature cares about is that you a) survive and b) reproduce.  Justice is a human value, not a natural condition.

Imagine how much zebras resent lions, or deer resent pumas. Nature couldn't care less.
