Exercises: The Speed of Truth

Part A: Comprehension and Application

A.1. List the eight variables in the Correction Speed Model from memory. For each, write one sentence explaining what it measures and whether it is a structural constraint or an acceleration lever.

A.2. The chapter identifies "alternative availability" as "the hidden key" to correction depth. Explain why fields don't abandon paradigms into a vacuum. Give an example where high alternative availability enabled deep correction and one where low alternative availability produced only cosmetic reform.

A.3. Choose one of the six anchor examples from section 22.4. Explain how its Correction Speed Model profile (the eight-variable scoring) predicts its actual correction timeline. Which variables were most important in that specific case?

A.4. The model identifies five acceleration levers. For each lever, propose one specific, concrete intervention that could be implemented in a university research department, a hospital system, or a government agency.

A.5. Explain the difference between "fast correction" and "good correction." Why might a crisis-forced correction (fast) be less valuable than a gradual correction (slow) that achieves deeper reform?

Part B: Analysis

B.1. Apply the full Correction Speed Model to a wrong consensus (historical or current) not discussed in this chapter. Score all eight variables, predict the correction timeline, and identify which acceleration levers could be most effective.

B.2. The chapter argues that "switching cost × defender power is the main brake on correction." Test this claim against the six anchor examples. Is there any case where high switching cost and high defender power were overcome without crisis? If not, what does this tell us about the limits of evidence-based correction?

B.3. Compare the Correction Speed Model to Kuhn's model of paradigm shifts in The Structure of Scientific Revolutions. What does the Correction Speed Model add that Kuhn's model lacks? Is there anything in Kuhn's model that the Correction Speed Model fails to capture?

B.4. The model's fourth limitation states that it is "itself subject to the failure modes it describes." What would an authority cascade, sunk cost trap, or consensus enforcement mechanism look like if they formed around the Correction Speed Model? How could the model be designed to resist its own institutionalization?

Part C: Synthesis and Evaluation

C.1. Design a "Correction Readiness Index" for a field or organization — a numerical score based on the Correction Speed Model that indicates how quickly the field could correct a wrong consensus if one were identified. Apply it to two fields you know and compare the scores.

C.2. The chapter identifies Pattern 7: "The model predicts why some fields self-correct and others don't." Choose two fields — one that self-corrects relatively well (aviation, some areas of medicine) and one that self-corrects poorly (forensic science, nutrition) — and compare their variable profiles. What structural features account for the difference? Could the poorly self-correcting field adopt features from the well self-correcting field?

C.3. The model does not include a variable for "public interest" — the degree to which the public is aware of and cares about the field's potential errors. Should it? Argue for and against adding a ninth variable. If you include it, where does it fit in the framework?

Part D: Mixed Practice (Interleaved)

D.1. A field has high evidence clarity but very high switching cost and very high defender power. Based on the model, what is the most likely correction pathway? Use concepts from Chapters 17, 19, and 21 to predict: will correction come through evidence, generational replacement, or crisis? What will happen after the correction?

D.2. You are advising a foundation that wants to accelerate the correction of a wrong consensus in criminal justice (forensic science methods). Using the model, identify which acceleration levers are most tractable, design three specific grant programs, and predict the timeline for meaningful change.

D.3. Two fields have the same Correction Speed Model profile on seven of eight variables, but differ on one: Field A has high alternative availability and Field B has low alternative availability. Both experience a crisis of similar severity. Using the model and Chapter 19's crisis framework, predict the different outcomes and explain why a single variable difference can produce dramatically different correction depths.

Part E: Deep Dive Extensions

E.1. Research the empirical literature on Planck's principle — studies that have tested whether scientific change is actually driven by generational replacement. Write a 500-word analysis of how the empirical findings relate to the Correction Speed Model's "correction mode" variable.

E.2. The chapter presents correction as a process occurring within a single field. But many corrections involve multiple fields (e.g., the ozone hole involved chemistry, atmospheric science, and policy). Extend the model to account for multi-field corrections. What additional variables or interactions would be needed?

E.3. Apply the Correction Speed Model to a current, active debate in any field where you believe the current consensus may be wrong. Score the eight variables, predict the timeline, and identify the most effective acceleration strategies. Note: this exercise requires you to take a position on a contested question — be explicit about your reasoning and be open to the possibility that you are wrong.
