The tobacco doubt campaign

Grades 9–12 Duration Two 50-minute periods Standards DE, NJ, TX, CA, IL
Objectives
  1. Describe how the tobacco industry manufactured doubt about a settled science from 1954 to 1998
  2. Identify manufactured doubt, front groups, paid experts, and false balance in primary documents
  3. Explain why "more research is needed" can be a technique rather than a request
  4. Apply the pattern to a current controversy and distinguish real scientific debate from manufactured doubt
Procedure

Before class

Students read the case study. Print the 1954 "Frank Statement" (available from the Truth Tobacco Industry Documents archive linked on the case study) and the 1969 "Doubt is our product" memorandum.

Period one: the documents

  1. The statement (15 min). Read the Frank Statement aloud. Ask students to mark every sentence that is literally true. Nearly all are. Then ask what the statement wants the reader to conclude, and whether that conclusion is true. The gap is the lesson.
  2. The memo (10 min). Read the 1969 memorandum. Compare it with the statement: same industry, fifteen years apart, one public and one private. What does the private document say the public one was for?
  3. The techniques (20 min). Walk through the case study's list: Manufactured Doubt, Front Groups, Paid Expert, False Balance, Cherry Picking, Message Discipline. For each, find the sentence in the documents or the fact in the case study that shows it.
  4. Close (5 min). Why did the industry never claim smoking was safe?

Period two: the pattern

  1. The playbook (10 min). Present the pattern as a checklist: a settled finding; an industry with a product at stake; a research body with an independent-sounding name; experts on retainer; a demand for more research; journalists giving both sides; decades of delay.
  2. Apply it (25 min). Groups take a current or recent controversy with an industry on one side (choose ones with a clear scientific consensus and a documented industry campaign; the case study's sources on acid rain and the ozone layer are safe examples) and test it against the checklist. Which boxes are ticked, and what is the evidence for each?
  3. The hard question (10 min). Real scientific debate exists. How does a reader tell it from manufactured doubt? Draw out the markers: who funds the doubters, whether the doubt is in the journals or in the press, whether it has moved in fifty years.
  4. Close (5 min). One sentence: what will you do the next time you read "the science is not settled"?
Assessment

A document analysis marking true sentences and the intended conclusion in the Frank Statement; a group checklist applied to a controversy with evidence for each box; a closing paragraph on distinguishing real debate from manufactured doubt.
