Why Being Wrong Can Be Right: Magical Warfare Technologies and the Persistence of False Beliefs
研究了刚果民主共和国东部冲突中与子弹防护相关的迷信和魔法，解释了这些错误信念为何在群体层面产生帕累托有效结果，从而得以持续存在。
Across human societies, one sees many examples of deeply rooted and widely held beliefs that are almost certainly untrue. Examples include beliefs about witchcraft, magic, ordeals, and superstitions. Why are such incorrect beliefs so prevalent and how do they persist? We consider this question through an examination of superstitions and magic associated with conflict in the Eastern Democratic Republic of the Congo. Focusing on superstitions related to bullet-proofing, we provide theory and case-study evidence showing how these incorrect beliefs persist. Although harmful at the individual-level, we show that they generate Pareto efficient outcomes that have group-level benefits.
