"Voodoo Histories" is a book by historian David Aaronovitch that explores the phenomenon of conspiracy theories throughout history. It examines how these theories often arise from a mix of fear, misunderstanding, and the desire to find simple explanations for complex events. The book delves into various historical events and figures, such as the assassination of President John F. Kennedy and the moon landing, analyzing how conspiracy theories have shaped public perception. Aaronovitch argues that these narratives can distort reality and influence societal beliefs, making it essential to critically evaluate the information we encounter.
