Jonathan Flint (UCLA behavioral geneticist, expert in the genetic determinants of depression and Depression Grand Challenge Executive Committee team member) shared background about the theory of the “warrior gene” in a blog post written for the Oxford University Press. Since the 1990s criminal defense lawyers have tried to argue that a mutation in the “warrior gene” mitigates responsibility for aggressive behavior. Flint highlights a 2021 New Mexico Supreme Court case which definitively ended the argument that a single gene mutation determines overall behavior.
