In this Hayek Lecture, Professor Jonathan Anomaly discusses some of the benefits and costs of emerging technologies that will allow parents to influence the genetic characteristics of their kids. Professor Anomaly began with an overview of some basic findings from behavioral genetics. He then discussed the coordination problems that are likely to arise when parents have access to technology that allows them to choose their children’s traits. Anomaly ended by defending principles justifying limited government intervention to solve coordination problems, drawing on insights from Hayek and Mill.
