I found a fascinating paper on why certain things creep people out, which is invaluable information for writers of horror, suspense, and anyone else who wants to play their reader’s nerves like a fiddle.
Why do some types of settings and some combinations of sensory information induce a sense of dread in humans? This article brings empirical evidence from psychological research to bear on the experience of horror, and explains why the tried-and-true horror devices intuitively employed by writers and filmmakers work so well. Natural selection has favored individuals who gravitated toward environments containing the “right” physical and psychological features and avoided those which posed a threat. Places that contain a bad mix of these features induce unpleasant feelings of dread and fear, and therefore have become important ingredients of the settings for horror fiction and films. This article applies McAndrew and Koehnke’s (2016) theory of creepiness to the study of classic horror settings and explores the role played by architecture, isolation, association with death, and other environmental qualities in the experience of creepiness and dread.
