To help us understand this important question, we’re joined by Jane Campbell Moriarty, the Carol Los Mansmann Chair in Faculty Scholarship and Professor of Law at the Thomas R.

Professor Moriarty is an expert on evidence, neuroscience and law, and legal and judicial ethics, and she has studied and written about the evidence used during the Salem Witch Trials.
