1211: Conspiracy Theories | Skeptical Sunday

What It Covers

Michael Regelio examines why conspiracy theories persist from medieval blood libel to QAnon, exploring the neurological, psychological, and social factors that make people susceptible to believing false narratives despite contradictory evidence.

Key Questions Answered

• •Neurochemistry predisposition: People with naturally higher dopamine levels show increased susceptibility to conspiracy beliefs. Studies demonstrate that even non-believers given dopamine boosts become more conspiratorial, while reduced beta frequency oscillations mean brains filter less noise, making random associations feel meaningful.
• •Proportionality bias drives belief: Humans instinctively reject explanations where small causes produce massive effects. The JFK assassination exemplifies this—people find one lone gunman killing the president unsatisfying, preferring elaborate conspiracies that match the event's magnitude over uncomfortable randomness.
• •Three core motivations fuel conspiracies: Epistemic motive seeks understanding in chaos, existential motive provides safety through imagined control, and social motive creates belonging. Believing powerful groups secretly control events feels less terrifying than accepting randomness, transforming believers from victims into heroes.
• •Critical thinking education prevents susceptibility: Schools must teach how to evaluate evidence and weigh sources, not just what to think. The failure lies in methodology—conspiracy theorists believe they're doing research but lack skills to assess credibility, making proper evaluation training essential.
