Exercises: How to Disagree Productively

Part A: Comprehension and Application

A.1. Define the "martyrdom trap" and explain why Semmelweis's dissent actually delayed the acceptance of hand-washing rather than accelerating it.

A.2. Explain the "credibility tax" and identify three structural features that make it disproportionate — why dissenting costs more credibility than defending.

A.3. For each of the Seven Principles, identify one historical case from this book where the principle was applied successfully and one where its absence contributed to the dissenter's failure.

A.4. Distinguish the three modes of dissent (insider reform, outsider challenge, circumvention). For each, identify the structural conditions under which it is the optimal choice.

A.5. Principle 7 (Build Undeniable Evidence) argues that demonstration is more powerful than argument. Explain why, using the crisis-driven correction framework from Chapter 19. What makes evidence "undeniable"?

Part B: Analysis

B.1. Design a dissent strategy for the following scenario: You are a junior researcher in a field where a core methodological assumption has been challenged by recent evidence, but senior figures continue to defend it. The field's Epistemic Health Checklist scores 4/10 on Dissent Tolerance, 3/10 on Outsider Access, and 6/10 on Replication Culture. Which mode of dissent should you use? Apply all Seven Principles.

B.2. Compare the Open Science movement's strategy (insider reform) with the Innocence Project's strategy (outsider challenge). What structural features of psychology vs. criminal justice determined which mode was appropriate? Could the Innocence Project have succeeded using insider reform? Could Open Science have succeeded using outsider challenge?

B.3. Principle 4 (One Heresy at a Time) is in tension with the reality that many failure modes operate simultaneously — your field might be wrong about several things at once. How do you handle a situation where the problems are interconnected and challenging one without the others seems incomplete?

B.4. The chapter argues that Marshall succeeded partly because he framed H. pylori as "better medicine" rather than as an attack. But Marshall also drank a petri dish of bacteria — a dramatic, confrontational act. Was Marshall's approach consistent across the Seven Principles, or did he use different strategies at different times? What does this tell you about the flexibility of the framework?

Part C: Synthesis and Evaluation

C.1. The Seven Principles are extracted from historical cases of successful dissent. Evaluate whether they are genuinely principles (universal guidelines) or merely patterns (things that happened to work in specific cases). Could a dissenter follow all seven principles and still fail? Under what conditions?

C.2. Some fields are so structurally compromised that no dissent strategy is likely to succeed from within. Identify a field from Part IV where the Epistemic Health Checklist scores are so low that even optimal dissent strategy would be insufficient. What would it take to change a field that is resistant to all three modes of dissent?

C.3. Apply the Seven Principles and Dissent Decision Framework to this book itself. If you believed that this book's thesis was substantially wrong — that failure modes are not structural but individual, or that institutions self-correct effectively — how would you challenge it? What strategy would be most effective?

Part D: Mixed Practice (Interleaved)

D.1. Using the Red Flag Scorecard (Chapter 31), the Epistemic Health Checklist (Chapter 32), and the Dissent Decision Framework (this chapter), design a complete intervention strategy for a specific claim in your field: (a) score the claim, (b) assess the field's health, (c) design the dissent strategy. Present all three analyses as a coherent package.

D.2. A colleague tells you they want to challenge a core assumption in your field but plans to do so by writing a single inflammatory paper attacking the leading figures personally. Using the framework from this chapter, advise them. What specific changes to their strategy would you recommend, and why?
