From the famous “Psycho” shower scene to “Poltergeist” and Chucky, America has a fascination with horror. Jeremy Dauber, professor of Jewish literature and American studies at Columbia University, joins host Krys Boyd to discuss how horror reflects worries of a collective culture, how the genre helped the fight against slavery and how changing gender roles spark new creations. His book is “American Scary: A History of Horror, from Salem to Stephen King and Beyond.”
