The Big Lie

What it is

Telling a lie so enormous and audacious that people assume it must contain some truth, because they cannot believe anyone would fabricate something so significant.

How it works

People can easily identify small lies but struggle to conceive that someone would completely fabricate a major claim. The scale of the lie itself becomes evidence of its truth in the audience's mind. When repeated frequently enough by authority figures, the Big Lie gains a veneer of legitimacy that makes questioning it feel unreasonable.

Real-world examples

  • •Historical dictatorships fabricating entirely fictional threats to justify military action or political repression.
  • •Corporations denying well-established scientific consensus (tobacco/cancer, fossil fuels/climate) for decades.
  • •Political movements claiming entire electoral systems are fraudulent without evidence to delegitimize outcomes.

Ethical guidelines

  • ●The Big Lie is among the most dangerous and destructive propaganda techniques in history.
  • ●It directly attacks the foundations of shared truth necessary for democratic society.
  • ●Those who deploy Big Lies bear responsibility for all downstream consequences.

How to defend against it

  • ►The scale of a claim does not correlate with its truth — demand evidence proportional to the claim.
  • ►Check if the claim has been verified by multiple independent sources with no coordination.
  • ►Be especially skeptical of dramatic claims that conveniently serve the interests of the person making them.
