…character traits are inherited, not taught.
I’m not talking about moral qualities, such as honesty, compassion and altruism. It may be that these can be cultivated.
I mean performance-enhancing virtues, like stick-to-it-ness and the ability to bounce back from defeat, what exponents of character education call ‘grit’.
There’s a growing body of evidence that these traits are largely hereditable, that is, encoded in our DNA. If you exhibit any of these qualities, it’s overwhelmingly likely that your parents did, too.
And insofar as a child’s upbringing has any impact on the emergence of these qualities, it’s the peers they associate with during adolescence that matter, not their teachers.
