"There's no magic formula for raising a child." This is a stark reality. I've seen families with very poor habits where at least one of the children abandoned the bad path of their older relatives and became a good citizen.

I've also seen seemingly healthy and good families where one of the children displays a wickedness beyond all doubt.

It's a somewhat complex issue because the evidence from sperm bank inseminations, with donor fathers of high IQs, shows that children with high intelligence are often born.

It's partly the result of the parents' efforts, partly luck, and genetics, the environment in which children grow up, and the people around them (teachers, friends, etc.) all play a role. It's truly a complex matter.
