The Psychology of Morbid Curiosity
The success of horror films, popularity of true crime, and prevalence of violence in the news implies that morbid curiosity is a common psychological trait. However, research on morbid curiosity is largely absent from the psychological literature. In this paper, I present a novel psychometric tool for assessing morbid curiosity, defined as a motivation to seek out information about dangerous phenomena, and use it to investigate the psychological nature of morbid curiosity. In studies 1 and 2 (n_total = 1370), the Morbid Curiosity Scale was developed and its relationship to personality was assessed. Morbidly curious individuals were rebellious, socially curious, and low in animal reminder disgust. Study 3 (n = 317) demonstrated that trait morbid curiosity is stable over 4-6 weeks and that morbidly curious individuals prefer movies where threat is a central theme. In Study 4 (n = 137), participants were presented with a choice between a morbid stimulus and a highly controlled non-morbid stimulus. Morbid curiosity predicted over half the variance (r2 = .53) in decisions to further investigate a morbid stimulus. These four studies provide evidence that morbid curiosity is a normally occurring psychological trait that can be accurately assessed using the new 24-item Morbid Curiosity Scale.
