Quiz: Planck's Principle and Its Exceptions

Q: Planck's principle states that science advances primarily through: Better experiments | B) Generational replacement — opponents die and new researchers grow up with the new idea | C) Government policy changes | D) Public pressure

B) Generational replacement. Reference: Section 17.1

Q: The Azoulay et al. (2019) study found that after prominent scientists die: Research quality declines | B) New publications from outsiders increase, suggesting the prominent scientist's presence suppressed new ideas | C) Nothing changes | D) The field collapses

B) Outsider publications increase — evidence that the gatekeeper suppressed new entrants and ideas. Reference: Section 17.1

Q: "Circumvention mode" correction means: Going around institutional rules | B) New evidence from a different direction renders the existing debate irrelevant | C) Convincing opponents through better arguments | D) Waiting for opponents to retire

B) Circumventing the debate — making objections obsolete rather than overcoming them. Reference: Section 17.4

Q: Which case best illustrates fast correction without generational replacement? Dietary fat hypothesis | B) Continental drift before 1960 | C) The ozone hole — Montreal Protocol within 2 years | D) Peptic ulcers

C) The ozone hole: clear evidence + existential threat + available alternative = very fast. Reference: Section 17.3

Q: "Planck's principle means that evidence is irrelevant to scientific change — only demographics matter."

False. Evidence is necessary but not sufficient. The prediction framework shows that evidence clarity is one of six variables. Planck's principle applies when other variables (switching cost, defender power) prevent evidence from producing change within a generation.

Q: "The ozone hole correction was fast because the science was better than the science behind other environmental issues."

False. The science was strong, but so is climate science. The speed was determined by structural variables: unambiguous evidence, existential threat, available alternatives, and weak defenders. The structural conditions, not the science quality, determined the speed.

5. "Planck's principle means that evidence is irrelevant to scientific change — only demographics matter."

Answer

**False.** Evidence is necessary but not sufficient. The prediction framework shows that evidence clarity is one of six variables. Planck's principle applies when other variables (switching cost, defender power) prevent evidence from producing change within a generation.

6. "The ozone hole correction was fast because the science was better than the science behind other environmental issues."

Answer

**False.** The science was strong, but so is climate science. The speed was determined by structural variables: unambiguous evidence, existential threat, available alternatives, and weak defenders. The structural conditions, not the science quality, determined the speed.

Section 3: Short Answer (2 points each)

7. Explain the "partial Planck" pattern. Why do some practitioners change their minds while others don't?

Sample Answer

Partial Planck: some practitioners (typically younger, less invested) adopt the correction based on evidence, while others (typically older, deeply invested) maintain the old position until retirement. The difference is structural: practitioners with more sunk cost, deeper Einstellung, and stronger identity investment face higher switching costs and are more resistant to change. The institutional consensus may shift (through voting or policy change) while individual holdouts persist.

8. A field has accumulated strong evidence against its dominant theory. But the theory is embedded in training programs, supported by major funders, and defended by the field's most prestigious leaders. Evidence-based arguments have been made for 10 years with minimal impact. Apply the correction speed framework to diagnose the stall and recommend a strategy.

Sample Answer

Diagnosis: High denominator (switching cost, defender power, institutional embedding). The numerator variables: evidence clarity may be strong but not *demonstrable* (statistical rather than visual). No crisis. Alternative may not be fully developed. Strategy: (1) Seek circumventing evidence — find a new approach that renders the theoretical debate irrelevant. (2) Lower switching cost — develop the alternative infrastructure (training, tools, textbooks). (3) Diversify funding — find funders not invested in the current theory. (4) Prepare for the next generational cohort — ensure new entrants learn both frameworks. (5) Stop trying to persuade the establishment and instead build the replacement they'll eventually adopt.
