<p>Predict what would happen if Harvard instituted a system of eugenics* allowing Harvards grads only to marry and raise children with other Harvard grads. Just a crazy idea–obviously not even remotely plausible</p>
<p>This is a “what if batman and robin fought superman and spiderman” type of question (I think batman has a good chance–intelligence and cunning), not a “what if we could stop global warming by cross breeding mangroves and oak trees” kind</p>
<p>In animal breeding, there is a phenomenon known as ‘regression to the mean’. When the parents reside at either extreme of the bell curve, be it height, intelligence, etc, their offspring will most likely deviate toward the center.</p>
<p>So, after 5 generations of Harvard inbreeding, the resulting offspring will probably resemble a Yalie.</p>
