Chapter 11 Exercises: Repetition and the Illusory Truth Effect

Propaganda, Power, and Persuasion

Exercise 11.1 — The Familiarity Audit (Individual)

Estimated time: 30 minutes

This exercise asks you to examine your own cognition before reading additional material — so complete it before consulting any external sources.

Make a list of five claims that feel true to you — claims about the world that you are confident in, but whose origin you cannot clearly trace. These are not claims you looked up or verified; they are things you "just know." For each claim:

  1. Write the claim in a single sentence
  2. Estimate when you first encountered it (roughly — year, or "childhood," etc.)
  3. Write down, as specifically as you can, where you believe you learned it
  4. Rate how confident you are in its truth (1 = very uncertain; 5 = completely confident)

After completing all five, reflect in writing (150–200 words): Could any of these beliefs have been built through repetition rather than evidence? Is there a way to distinguish, from the inside, between a belief grounded in evidence and a belief grounded in accumulated familiarity?

Optional extension: After completing the reflection, look up at least two of your five claims in a reliable source. Were any of them false, oversimplified, or more contested than your confidence rating suggested?

Exercise 11.2 — The Repetition Trace (Individual or Pairs)

Estimated time: 45 minutes

Select one claim from the following list — all are false or substantially misleading claims that have been widely repeated online:

  • "Humans use only 10 percent of their brains"
  • "The Great Wall of China is visible from space"
  • "Reading in dim light damages your eyesight"
  • "Napoleon Bonaparte was unusually short"
  • "Columbus proved the Earth was round" (a claim based on a misunderstanding of what navigators of the era believed)

For your chosen claim:

  1. Without verifying it first, rate how true it seems to you (1–7 scale)
  2. Look it up and establish the accurate information
  3. Try to trace where the false version originated and how it spread
  4. Find three examples of the claim being repeated in different media (news articles, social media posts, advertisements, film or television dialogue)
  5. Find three examples of the claim being corrected
  6. Compare the presentation style of the repetition instances and the correction instances: Which are more memorable? Which are more emotionally engaging? Which are shorter and easier to repeat?

Write a 300-word analysis: Why has this particular false claim persisted despite correction? What features of the false version make it "stickier" than the accurate version?

Exercise 11.3 — Slogan Analysis: Simplicity and Repeatability (Small Groups of 3–4)

Estimated time: 40 minutes

Your group will analyze political and commercial slogans from the list below, evaluating each one for its repetition-based influence potential.

Slogans for analysis: - "Ein Volk, Ein Reich, Ein Führer" (Nazi Germany, 1933–45) - "Make America Great Again" (U.S. political, 2016) - "Take Back Control" (Brexit, 2016) - "Just Do It" (Nike, 1988–present) - "Doubt is our product" (tobacco industry internal, 1969) - "The vaccines are safe and effective" (public health communication, multiple eras)

For each slogan, analyze: 1. Simplicity: How easy is it to remember and repeat? (1–5 scale) 2. Emotional charge: What emotional response does it trigger? Is the response specific or general? 3. Falsifiability: Can the claim be checked against evidence, or is it structured to resist falsification? 4. Repeatability: What features of its structure (rhythm, alliteration, parallel structure) make it easy to repeat? 5. Omission: What complexity is hidden by the simplification?

Discussion question: "The vaccines are safe and effective" appears in the same list as "Ein Volk, Ein Reich, Ein Führer" and "Make America Great Again." Does being accurate make a repeated slogan not propaganda? What criteria distinguish ethical repetition from propaganda repetition?

Exercise 11.4 — Designing for Stickiness (Individual)

Estimated time: 50 minutes

Your target community for the Inoculation Campaign needs to receive accurate information on a topic where false claims are circulating. Your task is to design a counter-message using the SUCCES framework (Simple, Unexpected, Concrete, Credible, Emotional, Story).

Step 1: Choose a false or misleading claim circulating in your target community.

Step 2: Identify the accurate information that should replace or counter it.

Step 3: Apply each dimension of the SUCCES framework to design a counter-message: - Simple: Reduce the accurate information to one memorable sentence. - Unexpected: Identify one element of the accurate information that violates a common expectation. - Concrete: Ground the abstract in a specific, tangible example or story. - Credible: Identify the most accessible evidence for the accurate claim. - Emotional: Identify the genuine emotional register appropriate to the accurate information. - Story: Draft a two-to-three sentence story structure (character, challenge, resolution) that carries the accurate information.

Step 4: Evaluate your counter-message: Is it more or less "sticky" than the false claim it is countering? What would you sacrifice to make it stickier?

Peer review: Exchange your counter-message with a partner. Does the counter-message they designed feel memorable and repeatable? Would you share it?

Exercise 11.5 — The Truth Sandwich Lab (Pairs)

Estimated time: 35 minutes

Below are three examples of journalistic corrections of false claims, written in traditional format (lead with the false claim, then correct it). Working in pairs, rewrite each correction in truth sandwich format (lead with truth, mention the falsehood minimally, return to truth). Then compare the two versions.

Example 1: "Despite widespread claims on social media that 5G mobile networks spread coronavirus, 5G technology is not capable of transmitting any biological material, and scientists have found no evidence of any connection between 5G infrastructure and COVID-19 infection rates."

Example 2: "The claim, widely repeated in political commentary, that crime rates have risen substantially over the past decade is contradicted by FBI data, which shows violent crime rates in the United States have declined significantly from their 1990s peaks, though they did increase somewhat in 2020–2021."

Example 3: "While anti-vaccine advocates have long claimed that the MMR vaccine causes autism, citing a 1998 study by Andrew Wakefield, that study was retracted by The Lancet in 2010 after investigators found Wakefield had manipulated data and failed to disclose a financial conflict of interest. Thirteen large subsequent studies involving millions of children have found no link between the MMR vaccine and autism."

After writing your truth sandwich versions, write a brief comparative assessment (150 words): Which version do you think would be more effective for an audience that has already encountered the false claim multiple times? Which would be more effective for an audience encountering the topic for the first time? Does your assessment depend on the specific topic?

Exercise 11.6 — The Algorithmic Repetition Audit (Individual)

Estimated time: 45 minutes over two days

Day 1: Spend thirty minutes browsing your usual social media feed or news aggregator without trying to evaluate any content — just scroll as you normally would. Make a tally of: - How many times you encountered each of three topics you chose in advance (any three topics of your choosing) - How many apparently independent sources made similar or identical claims about each topic - How many times you encountered the same specific claim (nearly verbatim) from different sources

Day 2: For the most frequently repeated claim from your tally: 1. Trace the claim to its earliest discoverable source in the current circulation cycle 2. Count the sharing cascade: how many of the instances you encountered appear to trace back to the same original? 3. Apply the five-step first-encounter logging process to the claim 4. Rate how credible the claim feels after this analysis versus how credible it felt before

Write a 200-word reflection: Did the audit change how you perceive the apparent diversity of the claims in your information environment?

Exercise 11.7 — The Nazi Repetition Infrastructure Analysis (Individual)

Estimated time: 35 minutes

This exercise asks you to analyze the Volksempfänger as an infrastructure investment from a strategic propaganda perspective.

  1. The Volksempfänger was subsidized to achieve mass penetration of German households. What specific feature of the illusory truth effect does mass simultaneous reach serve, compared to smaller-scale or sequential reach?

  2. The device was technically restricted to domestic frequencies. Analyze this restriction as a propaganda decision: what effect does it have on the information environment, and how does this effect relate to the repetition mechanism?

  3. Compare the Volksempfänger to contemporary social media algorithms as repetition infrastructure. In what ways are the two systems functionally similar? In what ways are they fundamentally different in their relationship to a central coordinating authority?

  4. If you were designing a counter-repetition infrastructure — a system designed to maximize the repetition of accurate information to a specific community — what would its key design features be? Use the Volksempfänger's design decisions as a negative template.

Answers should total 400–500 words across the four questions.
