Superstitious behaviors persist across time, culture, and age. Although often considered irrational and even potentially harmful, superstitions have recently been shown to have positive effects on stress levels, confidence, and ultimately, performance. However, it remains unclear how people conceive of superstitious behaviors, specifically, whether people attribute apparent superstitious efficacy to magical forces or to something else, such as reduced stress or increased confidence. In two studies we asked 6- to 9-year-old children and adults from the United States to rate how causally connected superstitious behaviors were to desired outcomes. In Study 1, participants provided open-ended responses to questions probing why they believed the actions were tied to the outcomes. Participants were more likely across ages to offer natural than magical explanations to explain the connection -- this became more pronounced with age. In Study 2, half the stories did not permit a plausible natural explanation, thus any perceived causal relation could only be attributable to magic. Participants were asked how connected the superstitious behaviors were to the outcomes. We found significant differences in ratings of connectedness between stories that held plausible natural explanations and those that did not in our adult sample only. Our findings suggest that people recruit their naïve psychology when reasoning about the efficacy of superstitious behaviors; however, children may also believe magic to be causally relevant.
