The Conspiracy Theory Handbook

The human tendency to formulate and propagate conspiracy theories is not new, but modern communication has made the spread of such theories exponentially faster and easier. In March 2020, cognitive behavior scientists Stephen Lewandowsky and John Cook published The Conspiracy Theory Handbook, which offers strategies for identification and response.


Domestic Terror Threat per FBI

A 2019 report from the FBI cites conspiracy theories as "a new domestic terror threat."  Per the report, “The FBI assesses these conspiracy theories very likely will emerge, spread, and evolve in the modern information marketplace, occasionally driving both groups and individual extremists to carry out criminal or violent acts.” 

Why They're a Threat

It is now easier than ever to rapidly consume and distribute conspiracy theories. And as we have seen with the 2016 #Pizzagate incident, these theories can have dangerous real world ramifications: 

  • Mass manipulation of public opinion.  
  • Increase in radicalized and extremist or violent behavior.  
  • Encourage targeting of specific people, places & organizations.
  • Mainstreaming of fringe & debunked ideas & “junk science.”
  • Contribute to polarization of society.
  • Undermine confidence in public leaders & institutions.

What Can We Do?



Per Sunstein & Vermeule (2009), governments can minimize the effects of conspiracy theories by aggressively rebutting as many of them as possible – preferably with the help of independent organizations – and by employing both public and private persuasion using countervailing facts.The resources contained within this guide - real time fact checking tools like apps and browser extensions and trusted organizations like Snopes, Politifact and - are essential to this ongoing effort.
