Card Stacking

What it is

Selectively presenting only the facts, arguments, and evidence that support your position while suppressing everything that contradicts it.

How it works

Unlike outright lying, card stacking uses true information — but only the convenient truths. By curating what the audience sees, the propagandist creates an overwhelmingly one-sided picture that appears to be comprehensive. The audience, seeing only supporting evidence, concludes that the evidence overwhelmingly supports the propagandist's position.

Real-world examples

  • •The Institute for Propaganda Analysis named card stacking as one of its seven devices in 1937.
  • •1954: the tobacco industry's Frank Statement cited selected scientists who doubted the cancer link while omitting the weight of the evidence.
  • •2012 US campaign: the Romney ad claiming Barack Obama had gutted welfare work requirements (PolitiFact's Lie of the Year) and the Priorities USA ad implying a laid-off worker's wife died because of Mitt Romney's Bain Capital (rated false) each assembled true fragments into a false whole.
  • •Documentaries: Fahrenheit 9/11 (2004) and 2000 Mules (2022, withdrawn by its distributor in 2024) presented real footage edited to a predetermined thesis.
  • •Corporate: annual reports that headline revenue growth while burying customer churn; up-to-50-percent-off claims computed on a single item.

Historical case studies

The Brexit bus and the £350 million figure

2016UK Referendum

The Vote Leave campaign painted "We send the EU £350 million a week, let's fund our NHS instead" on its battle bus. The number was a gross figure that ignored the UK's rebate, which never left the Treasury, and EU money spent in Britain. On May 27, 2016, the chair of the UK Statistics Authority, Sir Andrew Dilnot, said that using a gross figure in contexts implying it was net "is misleading and undermines trust in official statistics." The campaign kept the slogan. The number had a real source; the selection of which number to show did the work.

The five-sentence letter behind "less than 1% addiction"

1980–2017Pharmaceutical Marketing

A one-paragraph 1980 letter to the New England Journal of Medicine by Jane Porter and Hershel Jick reported that addiction was rare among hospitalized patients briefly given opioids. A 2017 bibliometric analysis in the same journal found it had been cited more than 600 times, most often as evidence that addiction is rare with long-term opioid therapy, a claim the letter never made, and that citations spiked after OxyContin's 1996 launch. The favourable fragment was circulated; the setting, the dose, the duration and the contrary evidence were left out.

Ethical guidelines

  • ●Presenting only favorable evidence while possessing contradictory evidence is a form of deception.
  • ●Audiences deserve the full picture, including evidence that complicates the narrative.
  • ●Honesty requires acknowledging strong counterarguments, not just building the strongest possible one-sided case.

How to defend against it

  • ►For any one-sided presentation, actively seek the evidence they're NOT showing you.
  • ►Ask: "What would someone who disagrees say, and what evidence would they cite?"
  • ►Be most skeptical of narratives where ALL the evidence conveniently supports one conclusion.

From the Defense Playbook

Consider the Oppositeminutes

Deliberately generate the reasons your current judgment might be wrong before acting on it, which measurably reduces confirmation-driven error in a way that merely trying to be fair does not.

Ask for the Denominatorseconds

Whenever you are shown a count ("4,000 complaints", "12 deaths", "9 out of 10 dentists"), ask "out of how many?", because a numerator on its own cannot tell you whether something is common, rare, rising, or falling.

Argument Mappingtakes practice

Draw the argument as a diagram, with the main claim at the top, the reasons for and objections against it beneath, and the support for each of those beneath them, so that gaps, repetition, and unsupported leaps become visible instead of being carried along by fluent prose.

Pick the Strongest Claimminutes

When faced with a pile of arguments, ask the other side to name their single best one, or choose it yourself, and examine that one thoroughly, instead of chasing every point or knocking down only the weakest.

TARES Self-Auditminutes

Before a campaign, advertisement, fundraising appeal, or pitch goes out, test it against the five TARES duties: Truthfulness of the message, Authenticity of the persuader, Respect for the audience, Equity of the appeal, and Social responsibility for the common good.
