How parents rear has no longterm effect on child's personality or mental health (edge.org)

Judith Rich Harris's research started with a seemingly preposterous null hypothesis: "How the parents rear the child has no long-term effects on the child's personality, intelligence, or mental health." But the evidence does not refute it. The evidence she presents is both fascinating and compelling, and is a great example of following the scientific results rather than what you assume to be correct.
