With empirical data from a large-scale online survey, this paper demonstrates that horror liking is a majority phenomenon and provides insight into the personality traits of horror users. A preference for horror media is predicted by the personality traits of sensation-seeking and intellect/imagination. Males are slightly more likely than females to seek out horror, and they do so more often and tend to prefer more extreme horror. The paper integrates the data from the survey into a cognitive-evolutionary theory of horror, according to which horror media function as threat simulation. Horror may provide users with psychological, behavioral, social, and moral insight; further, horror may serve as a context for the calibration of coping strategies, all of which may be adaptive.
