For many people worldwide, supernatural beliefs and attributions—those focused on God, the devil, demons, spirits, an afterlife, karma, or fate—are part of everyday life. Although not widely studied in clinical psychology, these beliefs and attributions are a key part of human diversity. This article provides a broad overview of research on supernatural beliefs and attributions with special attention to their psychological relevance: They can serve as coping resources, sources of distress, psychopathology signals, moral guides, and decision-making tools. Although supernatural attributions sometimes involve dramatic experiences seen to violate natural laws, people more commonly think of supernatural entities working indirectly through natural events. A whole host of factors can lead people to make supernatural attributions, including contextual factors, specific beliefs, psychopathology, cognitive styles and personality, and social and cultural influences. Our aim is to provide clinical psychologists with an entry point into this rich, fascinating, and often overlooked literature. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 19 is May 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
