1. The JAMA Network Open 2020 radiology study found that AI-flagged scan presentation caused radiologists to:
Correct. The study documented a confirmation bias amplification: radiologists anchored to AI flags, finding what the AI found and missing what the AI missed — even when the AI was deliberately set to be wrong.
The radiology study found automation bias in action: radiologists who saw AI-flagged scans first were less likely to find what the AI missed and more likely to "find" what the AI incorrectly flagged.
2. What term did MIT's Work of the Future task force use for durable human skills that retain value across technological generations?
Correct — MIT Work of the Future used "anchor skills" for capabilities like judgment, communication, and ethics that retain value across AI generations.
MIT Work of the Future's specific term was "anchor skills" — capabilities that anchor workers across technological disruptions by retaining value independent of which AI generation they face.
3. Research on skill decay (Ebbinghaus) cited in Lesson 4 shows that knowledge retention without reinforcement drops below what threshold within one week?
Correct. Ebbinghaus forgetting curve research shows retention drops below 20% within a week without reinforcement — the mechanism behind why episodic learning cannot build durable competency in a rapidly changing field.
The lesson cites research showing retention drops below 20% within a week without reinforcement. This cognitive reality is why recurring, applied learning infrastructure outperforms episodic, infrequent learning bursts.
4. The GitHub Copilot controlled study (September 2022) found that developers using the AI assistant completed tasks approximately how much faster than the control group?
Correct — the GitHub Copilot study reported a 55% speed improvement, one of the larger effect sizes documented in any productivity tool study.
GitHub's Copilot study found a 55% speed improvement — though distributed unevenly, with experienced developers capturing more of the gain through effective evaluation of suggestions.
5. Which skill ranked first on the WEF's list of fastest-growing skills by 2027?
Correct — analytical thinking topped the WEF list, with AI literacy ranking sixth.
Analytical thinking ranked first on WEF's list. AI literacy ranked sixth.
6. What did Burning Glass Institute's 2023 analysis find about which job roles listed prompt engineering as a requirement?
Correct — the cross-industry spread into non-technical professional roles was the key signal of prompt literacy becoming foundational rather than specialized.
Burning Glass found prompt engineering requirements spread across marketing, clinical, financial, and legal roles — not primarily technical positions — indicating a cross-industry literacy shift.
7. Goldman Sachs Research (2023) estimated that generative AI could automate approximately what share of current work tasks in the U.S. and Europe?
Correct. Goldman Sachs Research estimated roughly 25% of current work tasks could be automated by generative AI, with legal support, administrative roles, and customer service bearing the highest exposure.
The Goldman Sachs Research figure cited in the module was approximately 25% of current work tasks — with legal support, administrative roles, and customer service as the highest-exposure categories.
8. Google's 2021 announcement treating its Career Certificates as degree-equivalent for certain roles exemplified what broader trend?
Correct. Google's move reflected a market shift — portfolios, project records, and verifiable demonstrations of applied skill are gaining credibility as alternatives to traditional credentials, particularly relevant for AI-adjacent skill development.
Google's announcement exemplified a broader shift: demonstrated skill evidence — portfolios, projects, verifiable records — is gaining credibility as an alternative or equivalent to formal credentials, changing how workers should approach demonstrating new competencies.
9. The "R" in the RCTF prompt framework stands for Role. What does specifying a role accomplish?
Correct. Specifying a role — "as a senior employment lawyer" vs. "as a junior analyst" — shapes the perspective, vocabulary, and depth of the AI's response significantly.
Specifying a role shapes the AI's response framing and perspective — telling it to think from a particular expert's standpoint dramatically changes the output quality and relevance.
10. The BCG/Harvard/MIT/Penn study was published in which journal, and in what year?
Correct — published in Science, September 2023.
The 758-consultant BCG study was published in Science in September 2023.
11. The BCG / Harvard Business School study (Dell'Acqua et al., 2023) found that AI-augmented BCG consultants outperformed control groups by approximately what margin on standard analytical tasks?
Correct — 40% quality improvement on analytical tasks, with a 25% speed gain. The critical caveat was the reversal on tasks outside GPT-4's competence boundary.
Dell'Acqua et al. found a 40% quality improvement and 25% speed gain — with the crucial finding that performance reversed on tasks outside GPT-4's competence, requiring calibrated domain expertise to know when to use AI.
12. The ProPublica 2016 COMPAS analysis found that judges using the recidivism algorithm overrode its scores less than what percentage of the time?
Correct. Judges overrode COMPAS less than 20% of the time even when contextual information strongly contradicted the score — a textbook automation bias pattern with serious equity consequences.
Judges overrode COMPAS in fewer than 20% of cases despite strong contradicting contextual evidence — demonstrating automation bias at institutional scale.
13. In the MIT Work of the Future four-zone model, "AI-Assisted Human" (Zone 2) is best described as:
Correct. Zone 2 is the classic "AI in the copilot seat" configuration — the human drives, the AI surfaces information and risks.
Zone 2 is AI-Assisted Human: the AI provides options and flags risks, but the human owns all decisions. The AI informs without leading.
14. IBM CEO Arvind Krishna's May 2023 announcement about AI-driven hiring pauses specifically named which types of roles as most at risk?
Correct. Krishna specifically named back-office administrative functions — HR admin, document verification, scheduling — as the categories most vulnerable to AI replacement within five years.
Krishna specifically cited HR administration, document verification, and workforce scheduling as the role categories at risk — all back-office administrative functions with routine, well-defined tasks.
15. Kasparov's term "centaur" described human-computer chess teams in which the primary human contribution was:
Correct. The human's edge was metacognitive — knowing the boundary of the AI's reliability, not outperforming it computationally.
The human contribution in centaur chess was metacognitive: deciding when to trust the engine and when to override it. That judgment was the key differentiator.
16. MIT economist David Autor's "complementarity principle" states that workers who benefit most from automation are those who:
Correct. Autor's complementarity principle holds that technology creates gains for workers whose skills enhance or work alongside it. The radiologist who understands what AI imaging gets wrong is more valuable than either the radiologist or the AI alone.
Autor's complementarity principle is about skill type, not tenure or credentials. Workers whose skills enhance what AI does — rather than duplicate it — capture disproportionate gains from automation.
17. Which occupational category shows approximately 82% AI task exposure according to the Goldman Sachs / McKinsey data?
Correct — office and admin support leads the spectrum at ~82%.
Office and administrative support sits at approximately 82% exposure — driven by document processing, communication, scheduling, and data entry tasks that AI handles effectively.
18. What growth rate did Burning Glass find for prompt engineering job postings from Q1 2022 to Q3 2023?
Correct — 1,700% growth over that period, signaling a rapid shift in employer expectations.
Burning Glass documented 1,700% growth in prompt engineering job postings from Q1 2022 to Q3 2023.
19. Amazon's Upskilling 2025 program was economically motivated because:
Correct. Amazon's motivation was operational: its AI and automation deployments required a workforce capable of working alongside and managing those systems. The $700M investment was made because it was economically rational, not charitable.
Amazon's upskilling initiative was explicitly economically motivated — the company needed workers who could operate alongside expanding automation systems, and skills were chosen specifically to complement Amazon's AI deployments.
20. Klarna's AI assistant announcement (February 2024) cited the equivalent of how many customer-service agents' work being handled by the AI?
Correct — Klarna announced 700 agent equivalents in its February 27, 2024 press release.
