Our “creepy” reaction is both unpleasant and confusing, and according to one study (Leander, et al, 2012), it may even be accompanied by physical symptoms such as feeling cold or chilly. Following casual conversation with colleagues about the psychology underlying creepiness, I decided to explore what's been studied about the phenomenon. Given how frequently creepiness is discussed in everyday life, I was amazed that no one had yet studied it in a scientific way. The little bit of research that was at all relevant focused on how we respond to things such as weird nonverbal behaviors, and being socially excluded. These studies did not use the word creepiness, but their results implied that our “creepiness detector” may in fact be a defense against some sort of threat.
