G: Unfit

When a law student named Mark Bold came across a Supreme Court decision from the 1920s that allowed for the forced sterilization of people deemed “unfit,” he was shocked to discover that it had never been overturned. His law professors told him the case, Buck v Bell, was nothing to worry about, that the ruling was in a kind of legal limbo and could never be used against people. But he didn’t buy it. In this episode we follow Mark on a journey to one of the darkest consequences of humanity’s attempts to measure the human mind and put people in boxes, following him through history, science fiction and a version of eugenics that’s still very much alive today, and watch as he crusades to restore a dash of moral order to the universe.
