By a strange coincidence, I was called to jury duty for my very first time shortly after I started as director of a new MacArthur Foundation project exploring the issues that neuro­science raises for the criminal justice system. Eighty of us showed up for selection in a case that involved a young woman charged with driving under the influence, but most of my fellow citizens were excused for various reasons, primarily their own DUI experiences. Finally, I was called to the judge. “Tell me what you do,” he said.
