This week on Unorthodox: Scottish Jews get their own official tartan. Our Jewish guest is L. Jon Wertheim, executive editor of Sports Illustrated and the co-author of the book, This is Your Brain on Sports: The Science of Underdogs, the Value of Rivalry, and What we Can Learn from the T-Shirt Cannon. He tells us how he got into sports journalism, and what he thinks the least Jewish sports are. Our Gentile of the Week is Imani Perry, professor in the Center for African American Studies at Princeton. She tells us why she thinks Bernie Sanders should have more support from African American voters, and what she really thinks of Drake.
