Pseudoscience: a doctrine/belief masquerading as a science • non-falsifiable hypotheses • uncritical invetigation of data • failure to update theories • Paranormal: a subset whose explanations fall outside scientific canons • evaluate using scientific method • scientific, not magical worldview • analogy of criminal trial • burden of proof on challenger • extraordinary claims require extraordinary evidence

  11. Pseudoscience in the New Millennium • 4. Why do so many people believe? • reliance on anecdotal evidence • correlation does not imply causation • importance of a control sample • role of randomness&coincidence • placebo effect • wide-spread science illiteracy • basic mistrust of science • unwillingness to subject important beliefs to proper scrutiny

  12. Pseudoscience in the New Millennium • 5. Why should we be concerned? • Uncritical acceptance of some claims can harm society (eg., witch craze of 13th-16th C.; threats to certain species from altmed ingredients). • Scientists have a responsibility to inform the public, permitting people to make an informed choice. • Economic implications • Truthdoes matter.

Symptoms • > 50% of adults believe in astrology • 2-4x more astrologers than astronomers • millions have been abducted by aliens • >$300 million/yr on psychic hotlines • >$30 billion/yr on alternative medicines • >60% Americans believe dinosaurs and humans lived at the same time • 50th anniversary of Roswell drew far more people than any scientific meeting in history

  14. Pseudoscience in the New Millennium • 6. Conclusions • II. Remedy • The question is not, Should anything be done, but rather, What should be done? • Start small; every little bit helps • Become informed about pseudosciences • Challenge the media (politicians) when they pander to pseudoscience/paranormal • Always be accurate; never overstate a scientific claim • Challenge students/friends constructively; explain the scientific method
