In nearly every documented society, people believe that some misfortunes are caused by malicious group mates using magic or supernatural powers. Here I report cross-cultural patterns in these beliefs and propose a theory to explain them.

Using the newly created Mystical Harm Survey, I show that several conceptions of malicious mystical practitioners, including sorcerers (who use learned spells), possessors of the evil eye (who transmit injury through their stares and words), and witches (who possess superpowers, pose existential threats, and engage in morally abhorrent acts), recur around the world.

I argue that these beliefs develop from three cultural selective processes: a selection for intuitive magic, a selection for plausible explanations of impactful misfortune, and a selection for demonizing myths that justify mistreatment.

Separately, these selective schemes produce traditions as diverse as shamanism, conspiracy theories, and campaigns against heretics—but around the world, they jointly give rise to the odious and feared witch. I use the tripartite theory to explain the forms of beliefs in mystical harm and outline 10 predictions for how shifting conditions should affect those conceptions:

  1. People are more likely to believe in sorcerers as sorcery techniques become more effective seeming.

  2. People are more likely to ascribe injury to mystical harm when they are distrustful of others, persecuted, or otherwise convinced of harmful intent (“Accusations of Mystical Harm Track Distrust and Suspicions of Harmful Intent”).

  3. The emotions attributed to malicious practitioners will be those that most intensely and frequently motivate aggression (“Accusations of Mystical Harm Track Distrust and Suspicions of Harmful Intent”).

  4. People are more likely to attribute injury to mystical harm when they lack alternative explanations (“Mystical Harm Explains Impactful and Unexplainable Misfortunes”).

  5. The greater the impact of the misfortune, the more likely people are to attribute it to mystical harm (“Mystical Harm Explains Impactful and Unexplainable Misfortunes”).

  6. Practitioners of mystical harm are more likely to become demonized during times of stressful uncertainty.

  7. The traits ascribed to malicious practitioners will become more heinous or sensational as Condoners become more trustful or reliant on information from Campaigners.

  8. Malicious practitioners will become less demonized when there is less disagreement or resistance about their removal.

  9. The traits that constitute demonization will be those that elicit the most punitive outrage, controlling for believability (“Witches Are Well Designed to Induce Punitive Outrage”).

  10. Malicious practitioners whose actions can more easily explain catastrophe, such as those who employ killing magic compared with love magic, will be easier to demonize.

Societally corrosive beliefs can persist when they are intuitively appealing or they serve some believers’ agendas.
