Quiz: Critical Thinking and Practical Application

Test your understanding of hype detection, red flag identification, base rate reasoning, Bayesian analysis, and practical technology due diligence skills.

1. How many items are on the hype detection checklist, and what score range indicates a claim is "almost certainly overhyped"?

  1. 8 items; a score of 6-8
  2. 10 items; a score of 8-10
  3. 12 items; a score of 10-12
  4. 15 items; a score of 12-15
Show Answer

The correct answer is C. The hype detection checklist consists of 12 yes/no questions covering vague timelines, breadth of claims, absence of falsifiable predictions, "just engineering" dismissals, lack of commercial products, missing classical baselines, conflicts of interest, suppressed skepticism, missed past timelines, hypothetical markets, false analogies, and investment disconnected from results. A score of 10-12 indicates "almost certainly overhyped." Applied to quantum computing, the score typically reaches 10-12 out of 12, triggering every item on the checklist.

2. What is the primary reason science journalism systematically amplifies quantum computing hype?

  1. Science journalists are paid by quantum computing companies to write positive stories
  2. Structural incentives — exciting stories get clicks, journalists lack physics background, sources have financial stakes, and headline pressure overrides nuance
  3. Quantum computing stories are easier to write than other science topics
  4. Editors suppress negative quantum computing stories due to advertiser pressure
Show Answer

The correct answer is B. Science journalism amplifies hype through structural problems, not deliberate corruption. Incentive misalignment means exciting "breakthrough" stories get clicks while cautious analysis does not. Source dependence means journalists rely on researchers who have financial stakes in positive coverage. Technical illiteracy means most journalists cannot independently evaluate quantum claims. Headline pressure converts nuanced findings into "Scientists achieve quantum breakthrough!" The net effect is systematic bias toward overstating progress, with the public consuming headlines without the context needed for evaluation.

3. Apply base rate reasoning to the following claim: "Quantum computing will transform drug discovery within 10 years." What is the relevant base rate and what does it suggest?

  1. The base rate for drug discovery breakthroughs is approximately 80%, so the claim is likely correct
  2. The base rate for transformative technology claims is approximately 2-5% over 20 years, suggesting the claim has a very low prior probability of being accurate
  3. Base rate reasoning cannot be applied because quantum computing is unprecedented
  4. The base rate for physics-based technologies is 50%, suggesting even odds
Show Answer

The correct answer is B. Base rate reasoning asks: before considering this specific claim, what is the historical success rate for similar claims? Research on technology forecasting suggests that transformative technology claims ("will change civilization") achieve approximately 2-5% accuracy over 20 years. Claims requiring discontinuous breakthroughs before commercial value ("just engineering" applied to fundamental physics) have even lower base rates of 1-5%. This low prior should anchor the analysis before any company-specific evidence is considered. Base rate neglect — evaluating the specific claim without this historical context — is one of the most common cognitive errors in technology investment.

4. In Bayesian terms, if the prior probability of quantum computing viability is 0.001 and evidence has a likelihood ratio of 100:1, what is the approximate posterior probability?

  1. 100% — the evidence is overwhelmingly strong
  2. 50% — the evidence shifts the probability to even odds
  3. Approximately 9.1% — impressive evidence cannot fully overcome an extremely low prior
  4. 0.001% — the prior is too low for any evidence to change
Show Answer

The correct answer is C. Applying Bayes' theorem: \(P(\text{viable} \mid \text{evidence}) = \frac{100 \times 0.001}{100 \times 0.001 + 1 \times 0.999} \approx 0.091 = 9.1\%\). Even evidence 100 times more consistent with viability than failure only raises the posterior to about 9% because the prior is so low. To reach 50% probability, the evidence would need a likelihood ratio of approximately 1,000:1. This demonstrates why individual demonstrations, no matter how impressive, cannot overcome the low prior established by fundamental physics analysis. Only sustained, cumulative evidence across all breakthrough dimensions could shift the probability meaningfully.

5. Which of the following is a behavioral red flag in technology claims rather than a language or structural red flag?

  1. Using "quantum advantage" without specifying over what classical method
  2. Revenue projections that conflate quantum sensing with quantum computing
  3. A company claims a breakthrough but delays peer-reviewed publication, with announcements timed to funding rounds
  4. No paying customers for the core computation technology
Show Answer

The correct answer is C. The chapter distinguishes three categories of red flags. Language red flags include vague terminology like "quantum advantage" without classical baselines (option A). Structural red flags include no paying customers for core technology (option D) and conflated revenue projections (option B). Behavioral red flags involve actions rather than words: delaying publication after claiming breakthroughs, timing announcements to funding rounds or stock vesting dates, refusing independent benchmarking, and pivoting strategy without acknowledging the change. Behavioral red flags reveal misaligned incentives between the company's communication and its technical reality.

6. What are the four steps for critically reading a quantum computing press release?

  1. Check the author's credentials, count the number of citations, verify the journal's impact factor, read the abstract
  2. Identify what is claimed, identify what is omitted, follow the money, check the track record
  3. Read the headline, skim the body, check for peer review, share on social media
  4. Compare to competitors, check the stock price, review analyst ratings, evaluate the market size
Show Answer

The correct answer is B. The four-step press release analysis method is: (1) Identify what is claimed — strip away adjectives and extract specific, testable claims; (2) Identify what is omitted — look for missing classical baselines, error rates, cost per operation, timeline accuracy, and independent verification; (3) Follow the money — determine who funded the research, who benefits from the claim, and whether timing coincides with funding rounds; (4) Check the track record — find press releases from 2, 5, and 10 years ago and evaluate whether previous predictions were accurate. The most important information in a press release is often what it does not say.

7. A quantum computing company's pitch deck claims a $50 billion addressable market. Analyze this claim using the framework from the chapter.

  1. A $50 billion market validates the investment because it shows enormous potential returns
  2. The market size should be evaluated by checking whether it is based on demonstrated demand or "if it works" projections, and whether it conflates quantum computing with quantum sensing
  3. Market size claims in pitch decks are always accurate because they are subject to securities regulations
  4. The market size is irrelevant; only the technology readiness level matters
Show Answer

The correct answer is B. The chapter's pitch deck evaluation framework flags "Market Size" slides that project hypothetical markets based on "if it works" assumptions rather than demonstrated demand. A $50B addressable market for quantum computing typically assumes all ten breakthroughs succeed, ignores classical alternatives that already serve the same needs, and may conflate quantum sensing and QKD revenue with quantum computing. The critical questions are: Is this market based on actual paying customers or hypothetical future demand? Does the projection account for classical computing improvements that continually raise the bar? What is the base rate for market projections of this size being achieved?

8. How does the autonomous vehicle hype cycle serve as a partially resolved case study for understanding quantum computing hype?

  1. It shows that all hyped technologies eventually succeed if given enough time
  2. It demonstrates that hype corrections involve quietly extended timelines, scaled-back ambitions, and narrative shifts from "transform everything" to "useful in limited contexts"
  3. It proves that government regulation is the primary cause of technology failure
  4. It is irrelevant because autonomous vehicles and quantum computing use entirely different technologies
Show Answer

The correct answer is B. Autonomous vehicles provide a partially resolved case study: the hype cycle peaked around 2017-2019 with predictions of "full autonomy by 2020." When that failed, the industry quietly extended timelines, retreated to geofenced limited deployments, and shifted narratives from "will transform everything" to "useful in specific limited contexts." The same hype detection patterns appeared: vague timelines, dismissed skeptics, moving goalposts, and investment disconnected from results. This shows what a technology hype correction looks like in practice — and suggests quantum computing may eventually follow the same trajectory.

9. Evaluate which of the seven board-level questions would be most effective at cutting through quantum computing hype and why.

  1. "How many qubits does your system have?" because qubit count is the most important metric
  2. "What were your predictions for this year five years ago, and which did you meet?" because track record is the most objective, hardest-to-spin measure of progress
  3. "How much government funding have you secured?" because government backing validates the technology
  4. "Who are your competitors?" because competitive dynamics drive innovation
Show Answer

The correct answer is B. The track record question is the most powerful because it is objective, verifiable, and resistant to spin. Press releases from five years ago are public records. Either the company met its predictions or it did not. If a company predicted useful quantum computation by 2024 in 2019, and it did not happen, their current predictions carry proportionally less weight. This question applies Bayesian reasoning directly: past predictive accuracy is strong evidence about the reliability of current predictions. Qubit count alone (option A) is a misleading metric that ignores error rates, connectivity, and coherence.

10. Design a brief technology due diligence assessment for a quantum computing startup. Which phase of the five-phase framework should receive the most time and why?

  1. Phase 1 (Claim Analysis) because identifying hype early saves time on the remaining phases
  2. Phase 2 (Technical Assessment) because evaluating which of the ten breakthroughs have been demonstrated at commercially relevant scale is the most informative analysis for determining viability
  3. Phase 3 (Financial Analysis) because the expected value calculation is the only metric that matters
  4. Phase 5 (Synthesis) because integrating findings takes the most intellectual effort
Show Answer

The correct answer is B. Phase 2 (Technical Assessment, 1-2 days) should receive the most attention because it answers the fundamental question: has the technology demonstrated capability at commercially relevant scale? This phase evaluates Technology Readiness Level, determines which of the ten required breakthroughs have been achieved (not at laboratory scale, but at the scale needed for commercial operation), and compares claimed performance to best classical alternatives. Without a rigorous technical assessment, financial projections (Phase 3) are built on unfounded assumptions. Phase 1 is a useful screening tool but takes only 1-2 hours. Technical reality is the foundation upon which all other analyses depend.
