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. Term coined by Adolf Hitler in Mein Kampf (1925), attributed there to Jewish opponents; ironically deployed most systematically by Hitler's own regime.

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: Nazi propaganda blaming Germany's WWI defeat on a "stab-in-the-back" by Jews and socialists rather than military factors — a foundational Big Lie that enabled subsequent atrocities.
  • •Historical: Soviet-era denials of the Holodomor famine (1932–33), and later official denials of specific purges under Stalin, maintained across decades despite documentary evidence.
  • •Corporate: tobacco companies denying the cancer link for ~40 years despite internal knowledge; fossil-fuel companies denying climate science for ~30 years despite internal knowledge.
  • •Contemporary — US right: Donald Trump's claims that the 2020 US presidential election was "stolen" through widespread fraud, maintained despite dozens of court losses and unified rejections by state election officials of both parties.
  • •Contemporary — international: Jair Bolsonaro's pre- and post-election claims (2022 Brazil) that voting machines were systematically fraudulent, leading to the January 8, 2023 storming of government buildings.
  • •Contemporary — historically on the left: repeated official denials by the PRC of the June 4, 1989 Tiananmen Square killings, and denial of the scale of the Great Leap Forward famine deaths — the Big Lie is a technique of consolidated power, not a partisan technique.
  • •Contemporary — cross-partisan: sustained claims of stolen elections after losses that lacked corroborating evidence (e.g., some 2000 US "selected not elected" rhetoric on the left; 2016 "Russia stole it" overreach separate from documented interference; 2020 US "stolen" claims on the right).

Historical case studies

The stab-in-the-back legend

1918–1933Weimar Germany

Germany's military leaders knew in autumn 1918 that the war was lost and pressed the civilian government to seek an armistice. Within a year retired commanders were telling the public the opposite: that an undefeated army had been betrayed at home by socialists, communists and Jews, the "November criminals." The United States Holocaust Memorial Museum describes how the legend discredited the Weimar Republic's founders and became a staple of Nazi agitation. Hitler's own passage on the "big lie" in Mein Kampf accuses others of the technique while his movement practiced it.

The Soviet denial of the Katyn massacre

1943–1990Soviet Union

In 1940 the Soviet NKVD shot roughly 22,000 Polish officers and officials held as prisoners. When German forces announced the mass graves at Katyn in 1943, Moscow blamed the Germans, staged its own commission to say so, and tried to have the charge included at Nuremberg. A US congressional committee concluded unanimously in 1952 that the NKVD was responsible, but the official Soviet version was enforced in Poland and the USSR for nearly half a century, until Mikhail Gorbachev acknowledged Soviet responsibility in 1990. The lie was sustained not by plausibility but by the cost of contradicting it.

The "stolen election" claim

2020–2021United States

After the November 2020 election President Trump and his allies asserted that the result had been decided by large-scale fraud. The claim was rejected in dozens of lawsuits, including by judges he had appointed; his attorney general said the Justice Department had found no fraud on a scale that could have changed the outcome; and state recounts and audits confirmed the results. The House January 6th committee's final report documents that senior advisers told him repeatedly that the claims were false. Opinion surveys nevertheless showed a majority of his party's voters continuing to doubt the result, and the claim drew the crowd that attacked the Capitol on January 6, 2021.

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, including violence carried out in their name.
  • ●The technique is a tool of any actor with the power and reach to sustain a coordinated narrative — it is not the property of any political side. Evaluate specific instances on their evidentiary merits.

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 or shared incentives.
  • ►Be especially skeptical of dramatic claims that conveniently serve the interests of the person making them.
  • ►Notice the pattern: Big Lies are usually paired with attacks on the institutions (courts, journalism, science, election officials) that would normally refute them. If a claim comes bundled with "and don't trust anyone who tells you otherwise," that's a tell.

From the Defense Playbook

The Truth Sandwichminutes

When you have to correct a falsehood, open with the true statement, mention the falsehood once with a clear warning that it is false, and close by repeating the truth, so that the accurate version gets the prominent positions and the most repetitions.

Do Not Repeat the Myth in the Headlineminutes

When you correct a falsehood, put the true statement in the headline, subject line, first sentence, and image, and keep the false claim out of those positions, because most of the audience will see only that part and will carry away whatever it says.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
