Coltan Scrivner (Morbidly Curious: A Scientist Explains Why We Can't Look Away) is a psychologist, researcher, and author. Coltan joins the Armchair Expert to discuss always preferring to do nitty gritty research in the field rather than a sterile lab, studying human fun and fear responses to haunted houses in Denmark, and his four domains of morbid curiosity. Coltan and Dax talk about why in nature there’s a lot of danger without safe opportunities to learn about it, that bar fights actually take place a lot less than if we were chimps, and how bodily injury is an effective cue for danger and violence. Coltan explains ghost hunting in Georgia while not believing but seeing anyway, the 24-question scale he created for measuring morbid curiosities, and whether serial killers over-index in liking horror.
