Why Fear Can Be Fun

This Saturday, trick-or-treaters will head out in search of candy and maybe a good scare. This hour, we’ll talk about how fear works in our minds – and why we’re sometimes OK with it – with Margee Kerr. In addition to being the author of “Scream: Chilling Adventures in the Science of Fear” (Twelve), Kerr also works with one of America’s spookiest haunted houses.
