This is the 13th episode of The Show About Science, and people with triskaidekaphobia might be afraid to listen. Triskaidekaphobia is an extreme superstition regarding the number 13. In this episode, I talk to Stuart Vyse, a behavioral scientist, teacher, and writer. Stuart explains the science behind superstitions and phobias - so don’t be afraid to press play. A big big thanks to my Mom for recording this episode. “Triskaidekaphobia” by Jimmy Sutton’s Four Charms is available at http://www.histylerecords.com/four-charms/
