Summary: The 70 correct answers to the quiz about developments in UX and AI in 2025, including links to the full articles with more information.

 

Here are the answers to the quiz I recently posted about last year’s developments in UX and AI. All the questions were based on articles I wrote last year, but it should also be possible to answer them based on general knowledge.


If you have not already attempted the quiz, I strongly encourage you to do so before reading the rest of this article and viewing the answers.


Here are the answers. Do not read on if you have not attempted the quiz. (Nano Banana Pro)


1. In the context of "Slow AI" (tasks taking hours or days), what is the primary function of a "Return Recap" or "Resumption Summary"?

Correct Answer: C. To help the user reconstruct their mental model and context by summarizing the original intent, key decisions made, and current status.


For AI tasks that run for long periods ("Slow AI"), the user inevitably switches context to do other things. When they return, they suffer from “cognitive discontinuity:” they may have forgotten exactly what they asked for or why. The "Return Recap" is a specific design pattern intended to bridge this gap by showing the original prompt (Intent), what the AI did while the user was away (Decisions/Breadcrumbs), and where things stand now (Status). This allows the user to effectively evaluate the results or provide new input without having to re-read logs to figure out what happened.


When the AI has been running for a long time, it needs to welcome users back with a resumption summary. (Nano Banana Pro)


The most likely erroneous answer is D (display a simple progress bar). While progress indicators are essential for the "Execution" phase of cognitive latency, they are insufficient for the "Recovery" phase (resuming after an absence). A progress bar tells the user how much is done, but it fails to remind the user what is being done or why. For long-duration tasks, context recovery is a deeper usability problem than mere status tracking.



2. In AI-driven interfaces, teams sometimes run an A/B test, collect plenty of traffic, and still can’t get a stable winner. What is the most common underlying reason?

Correct Answer: B. The model’s probabilistic outputs inject extra variance into outcomes, so measured deltas can swing even when the UI change is real.


This is correct because classic A/B testing assumes the system is basically deterministic: if you hold everything still except the UI variant, then differences in outcomes can be attributed to that change. AI breaks that assumption. The same prompt can yield different outputs, and success becomes partly a function of whether the model “behaved” on that run. That adds an independent source of variance that can be big enough to swamp the smaller effect you’re trying to measure from a button label, layout tweak, or microcopy change. When the noise floor rises, the test may wobble between “winners” even with lots of traffic, because you’re trying to detect a faint signal while the AI is shaking the measuring instrument.


The most tempting wrong answer is usually A (novelty bias), because people have seen novelty effects in many product launches and redesigns. But novelty bias is a behavioral effect that typically produces a directional distortion (often short-lived) that you can model with time, cohorts, or holdouts. It doesn’t explain why a test stays unstable even after you have substantial traffic, because novelty is not the same thing as injecting a second, random variable into every user attempt. The “unstable winner” symptom is much more consistent with AI output variability increasing statistical noise than with users merely being briefly excited by a new paint job.



3. Recent research on human-AI collaboration identifies a "Trough of Mediocrity" where adding a human to the loop degrades performance. In which type of task is this negative value most likely to occur?

Correct Answer: B. Analytical decision-making tasks with a single correct answer, such as medical diagnosis or forecasting.


Research indicates that in "convergent" tasks—where there is a single correct objective answer—AI is often superior to the average human. When a human is added to the loop in these scenarios (e.g., detecting fake reviews, forecasting demand, diagnosing a disease), they often introduce bias, second-guess the correct AI, or add inconsistency. This results in the "human+AI" team performing worse than the AI alone. This is the "Trough of Mediocrity" or "Negative Value" of human intervention.


The most likely erroneous answer is A (Creative ideation and divergent thinking). This is actually the area where human-AI synergy is strongest. In creative/divergent tasks, there is no single right answer, and the combination of human curation/direction and AI generation consistently outperforms either working alone. The negative value phenomenon is specific to analytical/convergent tasks where AI has achieved superhuman accuracy.



4. According to the "Genii Shift" economic theory, what is the long-term impact of Transformative AI (TAI) on "routine" knowledge workers?

Correct Answer: A. They will be displaced as AI becomes capable of applying existing knowledge faster and cheaper, even in edge cases.


The Genii Shift posits that AI provides "genius on demand." Initially, this pushes human geniuses to the very edges of knowledge. However, in the long run, because the AI can perform both routine tasks (applying known knowledge) and difficult tasks (solving novel problems) efficiently, the "routine" knowledge worker loses their comparative advantage entirely. The theory predicts they will be displaced because the AI is a superior substitute for the application of existing knowledge.


The most likely erroneous answer is B (Their wages will increase significantly). This is the "complementary" view of AI, which holds true for the short term or for tasks where AI is a tool. The Genii Shift specifically addresses Transformative AI (TAI) in the long run, where AI becomes a substitute rather than a complement for routine cognitive labor, driving the value of that specific type of human labor down, not up.



5. In the "12 Steps for Usability Testing," what defines a strong problem statement during the definition phase?

Correct Answer: A. It must be solution-free, describing the user's struggle without prescribing a specific fix or feature.


A problem statement is the foundation of the study. To be effective, it must describe the user's pain point or struggle based on evidence (e.g., "Users are abandoning the cart at the shipping step") without jumping to a conclusion (e.g., "Users need a new button"). Keeping it solution-free prevents "solutionitis" and ensures the research actually investigates the root cause rather than just validating a premature fix.


The most likely erroneous answer is C (It must effectively outline the technical specifications). Technical specs belong in a requirements document or engineering ticket, not a user research plan. A usability study investigates human behavior and needs, not system architecture. Defining specs too early constrains the research and focuses on "can we build it?" rather than "should we build it?"



6. What is the "Third Scaling Law" of AI, and how does it differ from pre-training scaling?

Correct Answer: B. It involves scaling test-time compute (reasoning), where the model improves results by "thinking" longer during inference rather than just training on more data.

The first scaling law r

elates to pre-training (more data/compute = smarter model). The second relates to post-training (RLHF). The Third Scaling Law, exemplified by OpenAI's o1 and o3 models, relates to inference time. It proves that allowing the model to "think" (reason, explore paths, error-correct) for seconds or minutes before answering results in logarithmic improvements in intelligence. It scales intelligence by spending compute at runtime, not just training time.


The most likely erroneous answer is C (Scaling the physical size of data centers). While data centers are growing (e.g., Colossus), this is the mechanism for achieving scaling, not the law itself. The law describes the relationship between compute and intelligence. Furthermore, the Third Law specifically distinguishes itself by moving the compute spend from the training phase to the inference (usage) phase.



7. Why is Apple’s "Liquid Glass" UI style criticized from a usability perspective?

Correct Answer: B. It uses low-contrast text and translucent backgrounds that compromise readability and increase cognitive load.


Liquid Glass (seen in recent Apple iOS updates) relies on blurring, transparency, and layering. Usability heuristics emphasize clarity and legibility. Translucent backgrounds allow wallpapers or other UI elements to bleed through, reducing the contrast ratio for text and icons. This makes the interface harder to read (especially for visually impaired users) and increases cognitive load because the user has to mentally separate the foreground from the background noise.


The most likely erroneous answer is A (It relies too heavily on skeuomorphism). While Liquid Glass has some depth, it is not "skeuomorphic" in the traditional sense (like leather stitching or green felt). Skeuomorphism mimics real-world materials to aid understanding; Liquid Glass is an aesthetic choice about refraction and physics that often hinders understanding by reducing clarity.



8. What is the primary goal of "Generative Engine Optimization" (GEO)?

Correct Answer: B. To optimize content so that it is synthesized and cited by AI answer engines (like ChatGPT or Perplexity), rather than just ranking for keywords.


GEO is the evolution of SEO. As users switch from search engines (which provide lists of links) to AI answer engines (which provide synthesized answers), the goal changes. You no longer want to just "rank" #1; you want your content to be ingested, understood, and cited by the AI when it constructs an answer. This requires structuring content for machine readability, authority, and factuality so the Large Language Model treats it as a trusted source.


The most likely erroneous answer is A (To increase the number of backlinks). Backlinks are the currency of SEO (PageRank). While authority still matters for GEO, the primary mechanism is not link counting but content ingestion and synthesis. An AI might cite a source with fewer backlinks if that source provides a clearer, more structured answer that fits the AI's generation context.



9. Which three skills are identified as the critical "human" career skills for the AI era, replacing technical craft skills?

Correct Answer: D. Agency, Judgment, and Persuasion.


As AI automates execution (coding, writing, pixel-pushing), the value of "hard skills" declines. The remaining human value lies in Agency (the ability to initiate action and define what needs to be done), Judgment (the taste and ethics to evaluate AI outputs and decide which to ship), and Persuasion (the ability to align other humans toward a goal). These are the skills that direct the AI and manage the human ecosystem around it.


The most likely erroneous answer is A (Python programming, prompt engineering, and visual design). These are exactly the "technical craft skills" that the sources argue are being commoditized. Prompt engineering is explicitly called a "dying career," and visual design is increasingly handled by models like Nano Banana Pro. Relying on these is a trap.



10. What is the purpose of the "Study Similarity Score" (3S) in user research?

Correct Answer: B. To assess the relevance of secondary research findings to a current project based on user match, task match, and context match.


Secondary research (using existing reports) is much cheaper than primary research, but it carries the risk of being irrelevant. The Study Similarity Score (3S) is a heuristic tool to evaluate this risk. By scoring how closely the original study's users, tasks, and context match your current project, you can determine if the findings are "gold" (highly transferable), "silver" (useful with caution), or irrelevant.


The most likely erroneous answer is C (To calculate the statistical significance of A/B test results). 3S is a qualitative heuristic for evaluating validity and transferability of external knowledge; it is not a mathematical formula for calculating statistical significance (p-value) within a quantitative experiment.



11. Research on "AI Stigma" in healthcare revealed which paradoxical finding regarding patient perception?

Correct Answer: B. Advice labeled as coming from an AI was rated less reliable and empathetic, even when it was identical to advice labeled as coming from a human.


This finding highlights the "AI Stigma." When users know (or think) something is AI-generated, they apply a negative bias, perceiving it as colder and less trustworthy. However, in blind tests where the label is hidden, AI responses are often rated as more empathetic and higher quality than human doctor responses. The paradox is that the label changes the perception, not the content itself.


The most likely erroneous answer is C (Patients rated AI chatbots as having zero empathy). Patients did not rate AI as having zero empathy; they simply rated it lower than humans when they knew it was AI. In blind tests, they actually rated AI empathy higher than human empathy. The "zero empathy" distractor is an exaggeration of the finding.



12. In the "12 Steps for Usability Testing," why is it recommended to create a "scope document" that explicitly lists what is out of scope?

Correct Answer: B. To protect the project timeline from "scope creep" and manage stakeholder expectations about what the study will and won't cover.


The "scope document" functions as a strategic contract between the researchers and the stakeholders. Its primary utility lies in defining the boundaries of the study to prevent "scope creep"—the tendency for stakeholders to add small requests (like "just one more question") that cumulatively bloat the project and derail the timeline. By explicitly listing what is out of scope (e.g., "We won’t evaluate mobile layouts"), researchers can manage expectations and defend the study's velocity. This document forces a prioritization discussion early on, transforming wish lists into ranked realities.


The scope document is your defense against being overrun by scope creep. (Nano Banana Pro)


The most likely erroneous answer is A (To prevent stakeholders from seeing features that are not yet ready for testing). While it is true that prototypes often contain unfinished features, the purpose of the scope document is not secrecy or hiding the product roadmap. Stakeholders usually know what is being built; the document is a project management tool to ensure the research remains focused on specific questions rather than wandering into areas that are not ready or relevant for the current study.



13. What is the primary difference between an "AI-First Company" and an "AI-Native Company"?

Correct Answer: B. AI-Native companies are startups built from scratch with AI at the core, while AI-First companies are legacy firms retrofitting AI into existing structures.


An "AI-Native" company is defined by its origin: it is founded with AI as its fundamental operating system, meaning it has no legacy processes, workforce structures, or old technology stacks to overcome. In contrast, an "AI-First" company is typically a legacy organization (founded before the AI boom) that is strategically pivoting to prioritize AI. These companies face the difficult task of retrofitting AI into existing cultures and hierarchies, often having to run parallel workflows (old and new) during the transition.


The most likely erroneous answer is A (AI-First companies build their own foundation models, while AI-Native companies use APIs). The distinction is not based on the depth of the technology stack (building models vs. using wrappers) but on the organizational lifecycle and strategy. Many AI-Native startups rely entirely on APIs from providers like OpenAI to move fast, whereas some legacy AI-First companies might have the resources to build their own models but still struggle with legacy organizational inertia.

14. In the context of AI-generated content, what is the "AI Sandwich" workflow?

Correct Answer: B. A human provides the creative spark (top slice), AI generates volume/variations (filling), and a human curates/refines the result (bottom slice).


The "AI Sandwich" is a metaphor for a collaborative workflow between humans and AI in creative tasks. The "top slice" represents the human providing the strategic intent, creative spark, or "super-prompt." The "filling" is the AI generating a high volume of drafts, variations, or raw materials (divergent thinking). The "bottom slice" is the human returning to the loop to curate, edit, and refine the AI's output (convergent thinking), ensuring the final product meets quality standards.


In the “AI Sandwich” workflow model, AI provides the filling with most of the traditional work, whereas humans provide the top and bottom: initiating and judging the work. (NotebookLM)


The most likely erroneous answer is A (Using AI to generate the beginning and end of a video, while a human animates the middle). This describes a specific production technique, whereas the AI Sandwich is a broader conceptual model applicable to writing, design, coding, and strategy. It emphasizes the human role in initiation and finalization wrapping around the AI's execution.



15. Why is "Prompt Engineering" predicted to become an obsolete career path?

Correct Answer: C. Because as AI models improve, they better understand natural language intent, reducing the need for arcane syntax manipulation.


The necessity for "Prompt Engineering"—the skill of crafting complex, specific inputs to get desired outputs—is diminishing because AI models are rapidly evolving to understand natural human language and intent. As the models get smarter, the "articulation barrier" lowers, allowing users to simply state what they want in plain English without needing to know "magic spells" or technical syntax. The skill is being automated away by the intelligence of the model itself.


The most likely erroneous answer is A (Because AI models are becoming less capable of understanding natural language, requiring coding instead). The trend is the exact opposite. AI interactions are moving from command-based (requiring specific syntax) to intent-based (requiring only high-level goals), making the interaction more natural and less dependent on engineering the input.



16. What is the "Coasean Singularity" in relation to the structure of the firm?

Correct Answer: B. The theory that AI agents will reduce external transaction costs to near zero, making it efficient for firms to shrink and outsource most tasks to the market.


Ronald Coase’s theory of the firm posits that companies exist because using the open market (finding vendors, negotiating, enforcing contracts) is too expensive. The "Coasean Singularity" suggests that AI agents will reduce these transaction costs to near zero by handling negotiation and monitoring instantly and autonomously. This eliminates the economic rationale for large, bureaucratic firms, encouraging a shift toward tiny, hyper-efficient companies ("pizza teams") that outsource almost everything to the market.


The most likely erroneous answer is A (The point where AI becomes self-aware and takes over corporate governance). While AI automating management is a related concept, the "Coasean Singularity" is a specific economic reference to transaction costs and firm boundaries, not a science-fiction scenario of sentient AI seizing political control of the boardroom.



17. In "Slow AI" design, what is the purpose of "Conceptual Breadcrumbs"?

Correct Answer: B. To provide synthesized summaries of insights or intermediate conclusions during a long run, building trust in the AI's reasoning.


For AI tasks that run for hours or days ("Slow AI"), users suffer from anxiety about whether the AI is on the right track. "Conceptual Breadcrumbs" are status updates that go beyond technical logs (e.g., "downloaded file"). They report on the reasoning or findings (e.g., "Identified three main arguments against the hypothesis..."). This allows the user to monitor the AI's intellectual trajectory and intervene early if the logic is flawed, maintaining trust and control over long durations.


The most likely erroneous answer is A (To show the user the file path of the documents being analyzed). While "breadcrumbs" in web design refer to navigation paths, in the context of Slow AI, the term is metaphorical. It refers to the trail of reasoning left behind by the agent to assure the user of its progress, not a literal directory structure or file path.



18. What does the "Usability Scaling Law" predict will happen to user testing by 2035?

Correct Answer: B. Usability prediction by AI will surpass observational user testing for many common design tasks, reducing the need for empirical studies.


The "Usability Scaling Law" posits that as AI is trained on vast amounts of usability data (guidelines, past study results), its ability to predict usability issues will improve exponentially. By 2035, this predictive capability is expected to be accurate enough for standard interfaces that running expensive, slow human user tests will become redundant for most tasks. Empirical testing will retreat to a smaller role (~10%), focused on novel or complex domains where the AI lacks training data.


The most likely erroneous answer is D (The need for usability testing will disappear entirely because AI will design perfect interfaces instantly). The prediction is a rebalancing of methods, not a total extinction. Observational research will still be needed to generate new training data, handle edge cases, and validate truly novel designs that the AI cannot predict based on past data.



19. In the context of "Vibe Coding," what role does the human primarily play?

Correct Answer: C. Specifying the high-level intent (what the software should do) while the AI handles the implementation (how to do it).


"Vibe Coding" is a development paradigm where the human acts as the architect of intent. The user describes the desired outcome, behavior, or "vibe" of the application in natural language, and the AI writes the actual code to achieve it. The human focuses on the what and why, while delegating the technical how to the AI.


In vibe coding, the user expresses directorial intent and leaves it to the AI to figure out how to deliver the code. (Nano Banana Pro)


The most likely erroneous answer is A (Writing optimized Python code to ensure efficiency). This is the opposite of vibe coding. The defining characteristic of vibe coding is that the human stops writing the syntax and boilerplate code, relying instead on the AI to handle the programming language details based on high-level prompts.

20. How does the "Articulation Barrier" hinder AI adoption?

Correct Answer: B. Users struggle to translate their abstract needs into the precise prose required to get the desired result from an AI.


The "Articulation Barrier" is the gap between a user's intent and their ability to express that intent to an AI. Even if an AI is capable of a task, it cannot perform it if the user cannot describe it accurately in a prompt. This is particularly challenging for users with lower literacy or those trying to describe complex visual or musical concepts in words. It limits the utility of AI to those who are good at "prompt engineering" or writing.


The articulation barrier is caused by users’ inability to describe their needs in the format required by AI, not by how loudly or clearly they speak. (Nano Banana Pro)


The most likely erroneous answer is A (Users cannot speak clearly enough for voice recognition systems to understand them). The barrier isn't about the modality of input (voice vs. text) but the cognitive task of formulating the request. It is about the difficulty of formulating the request (finding the right words to describe a concept), not the physical act of speaking or the machine's ability to transcribe sound to text. Even if the AI hears the words perfectly, the user might not know which words to say to express their intent.



21. What is the "Drone War" concept regarding the information ecosystem?

Correct Answer: A. The conflict between AI generating untruthful information and AI used to screen/detect that misinformation.


The "Drone War" is a metaphor for the adversarial arms race in the information economy. On one side, bad actors use AI to generate cheap, high-quality misinformation ("cheaper lies"). On the other side, consumers and platforms use AI to detect, filter, and screen out that misinformation. It is a battle of automation vs. automation in the verification of truth.


In the upcoming “drone wars,” evil AI will drop misinformation and malware on users while good AI will detect it and defend us. (Nano Banana Pro)


The most likely erroneous answer is B (The use of physical drones to deliver data storage devices). While drones are used for delivery, in this specific context of "Transformative AI," the term is metaphorical. It refers to autonomous software agents ("drones") fighting over information quality, not physical hardware.



22. Why does the "Hamburger Menu" often fail on desktop interfaces?

Correct Answer: A. It violates the "Visibility of system status" heuristic by hiding core navigation options, increasing interaction cost, and lowering discoverability.


The hamburger menu was designed to save space on small mobile screens. When applied to desktop screens (where space is abundant), it gratuitously hides navigation options behind an icon. This lowers discoverability because users cannot see what is available without clicking. It increases interaction cost because navigation requires two clicks (open menu -> select option) instead of one, and it prevents users from forming a mental map of the site's features or structure at a glance.


The most likely erroneous answer is D (It is technically difficult to implement on desktop browsers). The failure of the hamburger menu on desktop is purely a usability failure, not a technical one. It is very easy to code; the problem is that it provides a poor user experience by hiding information that should be visible.



23. What is the "Boredom Problem" associated with the oversight of highly autonomous AI systems in AI-First companies?

Correct Answer: C. Humans are notoriously poor at vigilance tasks; as AI reliability increases, operators become complacent and inattentive, reducing their ability to intervene effectively during rare failures.


The "Boredom Problem" is a human factors challenge that arises when humans move from doing the work to overseeing AI agents that do the work. When an AI performs correctly 99% of the time, the human overseer has nothing to do. This lack of active engagement leads to "vigilance decrement," where the human zones out or loses situational awareness. Consequently, when the critical 1% failure eventually occurs, the human is mentally disengaged and ill-prepared to intervene in time to prevent disaster.


When nothing ever happens, it’s impossible for a human operator to keep up full alertness and constant attention on those boring screens. Then, when a problem does occur, the “fail-safe” human isn’t sufficiently alert to react quickly. (GPT Image 1.5)


The most likely erroneous answer is A (Employees become bored because the AI does all the creative work). While job satisfaction and the loss of creativity are valid concerns regarding AI displacement, the term "Boredom Problem" in this specific context refers to the cognitive difficulty of maintaining attention during passive monitoring (a safety issue), not the emotional state of feeling unfulfilled by one's career.

24. In Google's user testing of "Generative UI," why did users prefer the AI-generated interface over traditional websites 90% of the time?

Correct Answer: B. The AI acted as an "interaction synthesizer," stripping away the navigation tax of menus and scrolling to present only the components relevant to the immediate user intent.


Generative UI represents a shift from "navigation" to "synthesized interaction." Traditional websites impose a "navigation tax": users must hunt through menus, scroll past irrelevant sections, and decipher information architecture to find what they need. Generative UI removes this friction by dynamically assembling a bespoke interface that contains only the elements required to satisfy the user's specific intent at that moment. The preference stems from the radical reduction in interaction cost and cognitive load.


The most likely erroneous answer is C (The AI interface was faster to load). While speed is a factor in usability, the preference for Generative UI was driven by the content and structure of the interface, not just technical page-load speed. In fact, generating a UI on the fly might technically take longer than loading a cached static page, but the user's time to goal is shorter because they don't have to navigate a complex site structure.

25. What is the specific role of a "Forward Deployed Engineer" (FDE) in the context of UX discovery research for AI startups?

Correct Answer: C. To embed at the customer site, observe workflows, and build simplified prototypes to solve specific problems, which are later generalized into robust products.


The FDE role, popularized by Palantir and now common in AI startups, bridges the gap between abstract AI capabilities and specific business needs. FDEs work on-site with customers to identify high-value problems and build immediate, rough solutions ("gravel roads") using code and AI. These specific solutions serve as discovery research: once the product team sees what actually solves the customer's problem, they generalize those insights to build a scalable, polished product ("paved superhighway") for the broader market.


The most likely erroneous answer is B (To act as a salesperson). While FDEs contribute to account growth and are customer-facing, they are fundamentally engineers who build and prototype, not just sales staff who pitch existing products. Their value lies in "product discovery through deployment"—figuring out what to build by building it—rather than just selling what is already on the truck.



26. How does "Performative Privacy" differ from "Practical Privacy" in user interface design?

Correct Answer: B. Performative privacy refers to interfaces like cookie banners that create an appearance of control but often degrade usability without offering real protection, whereas practical privacy involves preventing actual data misuse.


"Performative Privacy" describes UI elements (like the ubiquitous GDPR cookie banners) that exist primarily to satisfy regulations or optics ("security theater"). They annoy users with interruptions while offering little genuine protection against data exploitation. "Practical Privacy" focuses on stopping actual harms, such as "dark patterns" that trick users into uploading their contacts or sharing location data. The source argues we should eliminate the performative annoyances and focus on rigorously punishing the practical violations.


The most likely erroneous answer is A (Performative privacy involves actual data encryption). This is the opposite of the definition. Encryption is a practical technical measure that protects data. Performative privacy is characterized by surface-level interactions (pop-ups, checkboxes) that demand user attention but rarely result in meaningful safety, often training users to blindly click "Agree" just to make the annoyance go away.



27. When designing for "Active Creation" with AI tools, which metric should replace "Time on Site" as a measure of success?

Correct Answer: A. Time to Fulfillment: The duration between a user forming an intent to create and achieving a satisfying output.


In the era of AI creation, traditional engagement metrics like "Time on Site" can be perverse; they reward keeping the user trapped in the interface. For creative tools, the goal is efficiency and agency. "Time to Fulfillment" measures how quickly the user can go from an idea ("I want a birthday card for my mom") to a completed, satisfactory result. A shorter time indicates a more powerful, usable tool that respects the user's intent.


The most likely erroneous answer is B (Clicks per Session). While fewer clicks can imply efficiency, "Clicks per Session" is often a vanity metric or ambiguous (high clicks could mean high engagement or high frustration). "Time to Fulfillment" is a more holistic, outcome-oriented metric that specifically targets the user's success in producing the creative asset they came to make.



28. How is the "Pancaking" of organizations expected to impact the career path of senior UX professionals?

Correct Answer: C. It will flatten hierarchies, making traditional management ladders obsolete and requiring seniors to contribute as high-level individual contributors who own the design vision directly.


"Pancaking" refers to the flattening of organizational structures. As AI makes small teams (e.g., 10 people) as productive as large ones (e.g., 100 people), the need for layers of middle management evaporates. The traditional career path of climbing the ladder from Manager to Director to VP (managing ever-larger teams) will disappear. Senior professionals must pivot to being elite individual contributors ("Founder Mode") who use AI to execute strategy directly, rather than managing others who do the work.


The most likely erroneous answer is A (It will create more middle-management layers). This contradicts the central thesis of the AI productivity revolution. AI facilitates coordination and reporting—the traditional tasks of middle management—allowing companies to operate with far fewer layers, not more. The prediction is a drastic reduction in managerial headcount.



29. In the debate over "Sovereign AI," what argument supports the idea of AI as "cultural infrastructure"?

Correct Answer: C. AI systems inevitably reflect the values of their creators; therefore, nations need their own models to preserve local values, culture, and language, preventing digital colonialization.


The "Sovereign AI" argument, articulated by Jensen Huang and Arthur Mensch, posits that AI is not just a neutral utility like electricity. It produces content (text, decisions, art) that is deeply imbued with the values, biases, and cultural norms of its training data and creators. If a nation relies entirely on foreign AI, it risks "digital colonialization," where its local culture and values are eroded by imported norms. Therefore, nations need domestic AI infrastructure to ensure their own culture is encoded and preserved in the intelligence layer.


The most likely erroneous answer is B (Every nation needs to manufacture its own GPU chips). While hardware independence is a related geopolitical issue, the specific argument for AI as cultural infrastructure focuses on the model's behavior and output (software/weights), not the silicon it runs on. A nation could buy foreign chips but still train a sovereign model to preserve its culture; the chips themselves are culturally neutral, the models are not.



30. What is the phenomenon of "Shadow AI" or "Secret Cyborgs" in the workplace?

Correct Answer: C. Employees using AI tools to do their jobs more efficiently but hiding this usage from their bosses and colleagues due to fear of stigma or obsolescence.


Research indicates that a vast majority (~69%) of employees use AI to help with their work but do not tell their employers. They hide it because they fear "AI Stigma" (being seen as lazy, cheating, or incompetent for not doing the work manually) and because they fear that if management knew AI did half their job, their salary or position would be cut. These "Secret Cyborgs" are increasing productivity, but the organization cannot learn from their innovations because the usage is hidden.


No matter how old-fashioned the outward appearance of an office, it probably has a large number of “shadow AI” users who hide their use of AI to appear more productive to the boss. (Nano Banana Pro)


The most likely erroneous answer is A (AI agents that run in the background without any human supervision). While "background agents" are a technological concept, "Shadow AI" in the corporate context specifically refers to unauthorized or hidden human usage of AI tools (parallel to "Shadow IT"), not the autonomous nature of the software itself.



31. What distinguishes a "Utilitarian" (Successful) metaphor from an "Ideological" (Failed) metaphor in UI design?

Correct Answer: B. Utilitarian metaphors prioritize user goals and discard limiting constraints of the source object, while Ideological metaphors prioritize the cleverness of the simulation.


Successful metaphors (Utilitarian) map the structure of a source concept to help users understand a system (e.g., "Desktop" or "Folders") but crucially break the metaphor where digital magic adds value (e.g., nested folders can go infinite levels deep, unlike physical ones). Failed metaphors (Ideological) become "cognitive cages" by adhering too strictly to the real-world source (e.g., Magic Cap's "walk down the hallway"), importing physical limitations that slow the user down for the sake of "realism."


The most likely erroneous answer is A (Utilitarian metaphors focus on visual realism). This is actually the opposite of the truth. Ideological metaphors often focus on visual realism (skeuomorphism) at the expense of function. Utilitarian metaphors focus on the functional model and are often abstract in appearance (like a folder icon that doesn't look exactly like a physical manila folder but acts like a container).

32. In the context of AI-generated visualizations, what is the concept of "Chart Pull" (as opposed to "Chart Junk")?

Correct Answer: B. The idea that attractive, even if somewhat decorative, visualizations attract users and incite them to engage with information that they would ignore if presented as a wall of text.


Edward Tufte famously coined "Chart Junk" to criticize decorative elements that distract from data. "Chart Pull" is the counter-argument that in an attention economy, especially with AI tools like Nano Banana Pro that make decoration easy, attractive visuals serve a vital function: they grab attention. Even if the illustration is decorative (like a tiger in a business suit), it pulls the user into the content, making them more likely to read the associated text or data.


The most likely erroneous answer is C (The tendency of AI to hallucinate incorrect data points). While AI hallucination is a real problem, "Chart Pull" specifically refers to the attentional magnetic quality of visual aesthetics. It is about the psychology of engagement, not data accuracy errors.



33. In the context of "User-Driven Design" enabled by vibe coding, how does the economic logic of design errors shift compared to traditional software development?

Correct Answer: B. The focus shifts from "Prevention" to "Correction" because the cost of fixing an error drops to near zero, making it more efficient to fix mistakes after detection than to prevent them perfectly.


In traditional development, preventing errors was paramount because the cost of fixing a design flaw after code had been written was estimated to be 100x higher than fixing it during prototyping. With AI-driven "vibe coding," the cost of generating and regenerating code drops to near zero. Consequently, the economic optimal strategy shifts: it becomes cheaper to build fast, identify errors in the living product (or high-fidelity prototype), and correct them instantly, rather than spending weeks on rigorous prevention strategies to ensure perfection before the first line of code is written.


Traditional software development was so expensive that the advice used to be to make sure to get everything right before shipping. Vibe coding is so cheap that you just try a new iteration if something isn’t what you want. (Nano Banana Pro)


The most likely erroneous answer is A (The focus shifts from "Correction" to "Prevention"). This reflects the legacy mindset of the pre-AI era, where development was scarce and expensive. In an era of abundance where AI can generate software instantly, the penalty for making a mistake is removed, invalidating the economic argument for heavy upfront prevention.



34. Analysis of the Hugging Face Hallucination Leaderboard suggests that AI hallucination rates follow a specific scaling law. What is the observed relationship?

Correct Answer: C. Hallucinations drop by approximately 3 percentage points for every 10x increase in the model's parameter count.


Data from the Hugging Face Hallucination Leaderboard reveals a regression where hallucination rates correlate inversely with model size. Specifically, for every 10x increase in the number of parameters (model size), the hallucination rate decreases by about 3 percentage points. This suggests that "bigger is better" regarding factual accuracy, and that scaling compute and data volume is a viable strategy for mitigating the hallucination problem over time.


The most likely erroneous answer is A (Hallucinations increase as models get larger). This is a common misconception based on the idea that a larger model has "more to confuse." In reality, larger models have more capacity to encode accurate world knowledge and nuanced relationships, reducing the likelihood of confabulation compared to smaller, less capable models.

35. What was the primary finding of the "GDPval" benchmark released by OpenAI, which compares AI performance to human experts on economically valuable tasks?

Correct Answer: B. Humans still won the majority of tasks (roughly 52-61%), but AI performance is rapidly improving and costs only about 1% of the human equivalent.


The GDPval benchmark compared AI performance against human experts on tasks representative of the US economy. While humans still outperformed the best AI models (winning 52-61% of comparisons depending on the specific model setup), the critical economic insight was the cost differential. The AI could perform these tasks for approximately 1% of the cost of the human experts. This massive cost advantage implies that even if AI is slightly less capable, its economic viability for many tasks is undeniable, especially as the performance gap closes.


The most likely erroneous answer is A (AI completely outperformed humans in all categories). This is incorrect; humans still held a slight edge in quality in late 2025. The significance of the benchmark lies in the trajectory (rapid improvement) and the economics (massive cost reduction), not in total human obsolescence at the time of the study.



36. In the context of AI-driven education, how does the impact on student learning differ when AI is used as a "Coworker" versus a "Coach"?

Correct Answer: B. Using AI as a "Coworker" (doing the work for the student) results in zero learning, whereas using AI as a "Coach" (guiding without doing) significantly accelerates skill acquisition.


This distinction highlights the "two faces" of AI in education. When AI acts as a "Coworker," executing tasks on behalf of the student (e.g., writing an essay), the student bypasses the cognitive effort required for neuroplasticity, resulting in no learning. Conversely, when AI acts as a "Coach" or tutor (providing explanations, feedback, and personalized pacing without doing the work) it accelerates learning significantly, as evidenced by studies showing students achieving two years' worth of progress in six weeks.


In the gym and when learning, the same rule applies: if you do the work yourself (with AI as a coach to optimize the workout/learning session), you get stronger/wiser. If you let AI do the work, you don’t get these results. In the workplace, having AI do the work improves productivity, but this is a very different scenario from being a learner. (Nano Banana Pro)


The most likely erroneous answer is A (Using AI as a "Coworker" accelerates learning by showing perfect examples). While examples are useful, active engagement is required for learning. Relying on AI to perform the work ("Coworker" model) removes the necessary struggle and practice, leading to dependency rather than skill acquisition.



37. When designing an email newsletter subscription flow, what is the best practice for the "Welcome Email" to maximize engagement?

Correct Answer: B. Send it immediately, and use it to set the tone, deliver incentives, and encourage a next action (like replying or whitelisting), taking advantage of its typically high open rate.


The welcome email typically has the highest open rate (often >60%) of any email a newsletter sends. Best practice dictates sending it immediately while the user's intent is fresh. It should be used strategically to confirm the subscription, deliver any promised incentives (e.g., a PDF), set expectations for future content, and encourage a small interaction (like a reply) to signal to email providers that the sender is trusted, thereby improving future deliverability.


The most likely erroneous answer is A (Send it 24 hours later). Delaying the welcome email is a mistake because the user may forget they subscribed, leading to confusion or a higher likelihood of marking the email as spam. Immediate gratification and confirmation are crucial for cementing the new relationship.



38. In the proposed framework for estimating AI's rate of progress in UX skills, which type of human behavior is predicted to be the fastest for AI to master and simulate?

Correct Answer: B. General aesthetic preferences (e.g., visual attractiveness) that are largely determined by genetics and evolution.


I predicted that AI will be fastest at learning to simulate general human behaviors that are rooted in biology and evolution, such as visual preference (what looks attractive?). These traits are universal and heavily represented in training data. In contrast, nuanced, context-dependent behaviors involving complex tools are harder for AI to simulate because it lacks the "embodied cognition" and lived experience of a human user.


The most likely erroneous answer is C (Domain-specific workflows in specialized industries). This is predicted to be one of the slowest areas for AI to master. Simulating a specialized expert user requires deep contextual understanding and detailed interaction data that is often scarce or tacit, unlike universal aesthetic preferences which are abundant in general data.



39. You’re trying to earn citations in an AI answer engine that disproportionately pulls from community discussion rather than polished institutional sources. Which content move best aligns with that observed citation bias?

Correct Answer: A. Publish and seed robust community Q&A and discussion that surfaces real edge cases and practical answers (the kind of material people debate in forums).


This is correct because some answer engines don’t merely lean on institutional, editorial sources; they heavily mine the messy, lived-in parts of the web where people argue, compare, warn, and recommend. In the GEO article’s summary of citation patterns, Perplexity is described as favoring community and niche sources, with Reddit dominating its top citations. If an engine’s diet is discussion threads, reviews, and practical troubleshooting, then the strategy that fits is to create or support exactly that kind of content: real questions, concrete answers, edge cases, and the social proof that only shows up when humans talk to each other in public.


The most likely erroneous answer is C (buying backlinks), because it’s the classic SEO play and it feels respectably “algorithmic.” But it’s a move optimized for the wrong selector. Backlinks help in a world where a link graph is a primary signal for ranking web pages; they do not automatically place you inside the pool of community discourse that certain answer engines cite disproportionately. The GEO article’s practical implication is that you must manage off-site channels—forums and communities included—because those venues themselves are strong citation feeders. You can buy links forever and still be absent from the very places the engine prefers to quote.



40. When designing error messages (Usability Heuristic #9), how should a designer handle a "Vending Machine" style error like "Out of Order"?

Correct Answer: C. Rewrite it to diagnose the problem (e.g., "Cash mechanism full") and offer a solution (e.g., "Use card or visit Machine #2").


Heuristic #9 requires that error messages help users recognize, diagnose, and recover from errors. A vague "Out of Order" sign fails this because it doesn't explain the cause or the remedy. A usable message must be specific (diagnose: the cash bin is full) and constructive (recover: pay with a card or go to the machine next door). This turns a dead-end error into a manageable situation.


The most likely erroneous answer is B (Rewrite it to be polite). While politeness is generally good, it does not solve the usability problem if the message remains vague. "We are so sorry, but this machine is feeling under the weather" provides no diagnostic information or recovery path. Usability prioritizes utility and recovery over mere politeness.

41. How does the psychological mechanism of "Predictive Processing" support the effectiveness of good UI metaphors?

Correct Answer: B. It provides the brain with ready-made "priors" or hypotheses about how the interface will behave, reducing the error signal (surprise) when the system acts in alignment with the metaphor.


Predictive processing theory posits that the brain constantly generates hypotheses ("priors") about what will happen next. A good metaphor (like "Desktop") supplies a robust set of priors: users expect folders to contain documents and trash cans to hold deleted items. When the system behaves according to these expectations, the brain's prediction error is minimized, reducing cognitive load and making the interface feel intuitive.


In predictive processing, the brain generates a hypothesis about what will happen as a result of an action (here: dragging a document to the trash). A bad UI metaphor (here: the trash can doesn’t delete) would create the wrong predictions, leading to usability problems. (Nano Banana Pro)


The most likely erroneous answer is C (It forces the user to process every pixel on the screen). This describes a lack of predictive processing. The benefit of a metaphor is precisely that it prevents the need to process every pixel from scratch; the brain can skip detailed processing because it successfully predicted the outcome based on the metaphor.

42. What is the concept of "Disposable UI" in the context of Generative UI?

Correct Answer: C. Interfaces that are generated on-the-fly by AI for a specific, momentary user intent and then discarded, rather than being built to last for years.


Generative UI marks a shift from permanent applications to ephemeral interactions. In this model, the AI generates a bespoke user interface (e.g., a specific comparison table or interactive widget) instantly to satisfy a user's immediate query. Once the task is done, that UI is discarded. It is "disposable" because it is cheap to generate and tailored to the moment, rather than a static asset maintained by engineers for years.


The most likely erroneous answer is A (Interfaces that are deleted from the server after 24 hours). This implies a security or data-retention policy. "Disposable UI" refers to the utility and lifecycle of the interface from the user's interaction perspective—it exists only for the duration of the specific intent, not a fixed server timeout.

43. Which "Prompt Augmentation" design pattern allows users to construct complex prompts by selecting pre-built components from menus (e.g., camera angles, lighting styles) rather than typing everything?

Correct Answer: C. Prompt Builders.


"Prompt Builders" utilize a GUI (like dropdown menus or selectable chips) to let users assemble a prompt from predefined components. This pattern lowers the articulation barrier by allowing users to recognize options (e.g., "Cinematic Lighting," "Wide Angle") rather than having to recall the specific technical terminology and type it out. It bridges the gap between natural language and structured input.


A prompt builder allows the user to construct a prompt from pre-existing building blocks that each specify an aspect of the desired result. (Nano Banana Pro)


The most likely erroneous answer is D (Reverse Prompting). Reverse prompting works in the opposite direction: it takes an existing output (like an image) and generates the text prompt that would create it. Prompt Builders work in the forward direction (creating the prompt) but use GUI elements to assist the process.



44. In the context of AI-driven Generative Engine Optimization (GEO), why is it recommended to adopt a "Cross-Funnel Holistic View" rather than optimizing individual pages for specific stages of the buying journey?

Correct Answer: A. AI agents effectively traverse the whole journey in one sweep and cite sources that demonstrate broad authority across the topic cluster, not just one stage.


This is correct because the AI is not behaving like a human skimming a sequence of pages. It behaves more like a delegate: it gathers material across the entire decision space and then compresses it into a single answer. In the GEO article’s framing, the agent effectively runs TOFU, MOFU, and BOFU research “simultaneously” to synthesize a comprehensive response. That means the winner is often the brand (or source) that has built credible coverage across the cluster of related questions—definitions, comparisons, and high-intent “best choice” guidance—because that breadth gives the AI enough material to trust and to cite. UX Tigers


The most likely erroneous answer is B (the one-page-per-domain myth) because it sounds like a plausible technical limitation and offers a tidy explanation. But it contradicts how these systems actually behave in practice: they cite multiple sources, and the article describes them as synthesizing from many public sources to build their understanding of a brand or topic. The problem is not that splitting content hides it from a page-limited reader. The problem is that stage-specific pages, optimized in isolation, don’t necessarily create the broad topical authority the AI needs when it is assembling a unified answer.



45. What is the "Measurement Gap" identified by economists regarding Transformative AI (TAI)?

Correct Answer: B. The failure of traditional economic metrics like GDP to capture the value of TAI, largely because many AI services are provided at zero monetary cost (zero-price output) and improve quality in intangible ways.


The "Measurement Gap" refers to the disconnect between traditional economic statistics and the actual welfare provided by AI. GDP measures market transactions and prices. However, AI often provides immense consumer benefits—such as better health outcomes, personalized education, or entertainment—at zero marginal cost to the user (e.g., free tiers of LLMs) or through significant quality improvements that don't show up in price tags. This leads to a "paradox of efficiency" where economic welfare might increase dramatically even while measured GDP remains flat or declines because the cost of services drops.


The most likely erroneous answer is A (The inability of AI to measure physical distances). While this sounds like a technical limitation ("measurement"), in the context of the economic analysis of Transformative AI, the "gap" refers to econometrics and value capture, not physical spatial sensing.



46. According to the "12 Steps for Usability Testing," what is the primary purpose of Step 7 (Pilot Testing)?

Correct Answer: C. To "test the test" (validate the script, tasks, and technology) rather than to test the design itself, ensuring the main study runs smoothly.


Pilot testing serves as a dress rehearsal for the research study. Its specific goal is to identify flaws in the methodology—such as confusing task instructions, broken prototype links, or faulty recording equipment—before real participants arrive. Data collected during a pilot is usually discarded because the protocol often changes immediately after. The objective is to ensure the main study yields valid data, not to gather design insights from the pilot participant.


The most likely erroneous answer is B (To gather a small amount of quantitative data to set a baseline). A pilot test typically involves only one or two users, which is statistically meaningless for setting quantitative baselines. Using pilot data for quantitative measurement would introduce noise and is contrary to the purpose of refining the study protocol.



47. In the psychological mechanics of UI metaphors, what is "Chunking"?

Correct Answer: B. A cognitive process that turns a sequence of small steps (perception, attention, motor action) into a single meaningful unit labeled by the metaphor (e.g., "drag to trash"), reducing working memory load.


Chunking is a mechanism where the brain groups multiple individual items or actions into a single, higher-level cognitive unit. In UX, a metaphor like "drag to trash" allows the user to think of a complex sequence (select file, hold mouse button, move to specific coordinates, release button) as one single action: "delete." This drastically reduces the load on working memory and speeds up decision-making because the user plans and executes at the level of the "chunk" rather than the individual micro-steps.


The most likely erroneous answer is A (Breaking a long webpage into smaller pages). This describes "pagination" or "content splitting," which is a layout decision. While it involves breaking things up, "chunking" in cognitive psychology and metaphor theory specifically refers to the mental binding of information to aid memory and processing, not the visual separation of HTML content.

48. Which "Prompt Augmentation" design pattern utilizes a hybrid user interface with elements like sliders to vary the prompt along specific dimensions (e.g., length, reading level)?

Correct Answer: A. Parametrization.


Parametrization abandons the pure text-prompting paradigm in favor of standard GUI elements. It provides sliders, toggles, or dropdowns that allow users to adjust specific variables (parameters) of the AI's output, such as length, tone, or reading level. This helps users visualize the dimensions of control and modify the output without needing to articulate complex constraints in natural language sentences.


The most likely erroneous answer is C (Style Galleries). While Style Galleries are a form of prompt augmentation, they typically rely on visual examples to allow users to select an aesthetic (like "oil painting" or "cyberpunk"). Parametrization is distinct because it uses scales and dimensions (often quantitative or ordinal, like 1-to-5 length or Kindergarten-to-PhD reading level) rather than just selecting a visual style.



49. What is the specific innovation in the user interaction model of OpenAI's "Deep Research" tool compared to standard chatbots?

Correct Answer: C. It takes initiative in the dialogue by asking the user clarifying follow-up questions to refine the research scope before starting the work.


The "Deep Research" tool shifts the interaction model from a passive "user asks, AI answers" dynamic to a "shared dialogue initiative." Before embarking on the resource-intensive research task (which can take minutes), the AI proactively asks the user clarifying questions (e.g., "Do you want to focus on hiking or skiing?" or "What is your budget?"). This ensures the AI understands the constraints and context, reducing the likelihood of a wasted run and increasing the relevance of the final report.


The most likely erroneous answer is B (It acts as a passive respondent). This describes the standard chatbot interaction model (like GPT-3.5 or basic search). The innovation of Deep Research is precisely that it breaks this passive mold and acts as an active partner that seeks clarification, mimicking a human research consultant.

50. In the "Slow AI" framework for long-running tasks, what is the purpose of "Tiered Notifications"?

Correct Answer: B. To manage user attention by distinguishing between critical blocks (immediate alert), quality-improving decisions (in-app nudge), and simple completion notices, avoiding notification fatigue.


For AI tasks that run for hours or days, constant notifications would be overwhelming ("notification fatigue"). Tiered notifications solve this by categorizing alerts based on urgency. Tier 1 (Critical) interrupts the user immediately because the process is blocked. Tier 2 (Quality decisions) notifies gently, allowing the AI to continue working while waiting for input. Tier 3 (Completion) notifies based on user preference. This respects the user's attention while ensuring the AI task doesn't stall unnecessarily.


Sorting messages by priority is a well-established practice that ensures attention to the most important issues first. AI should embrace this idea. (Seedream 4.5)


The most likely erroneous answer is A (To charge users different prices). While cost control is a factor in Slow AI (budgeting tokens), "tiered notifications" specifically refers to the interaction design strategy for alerting the user, not the pricing model of the service.



51. Why is "Breaking the Browser" (specifically the Back button) considered a top UI annoyance?

Correct Answer: B. Because it violates a firmly established user expectation and mental model that the Back button will return them to the previous state, causing disorientation and loss of control.


The Back button is the user's "emergency exit" and primary navigation tool. Users have a deeply ingrained mental model that clicking Back will reverse their last action or return them to the previous screen. When a website breaks this (e.g., by trapping them in a redirect loop or doing nothing), it strips the user of control and freedom (Heuristic 3), causing panic, disorientation, and a feeling that the site is broken or malicious.


The most likely erroneous answer is C (Because it makes the website load slower). While performance is important, the specific grievance with "breaking the browser" is about navigation control and predictability, not page load speed. A fast-loading page that traps the user is still a major usability failure.

52. According to the "Usability Scaling Law" theory, what represents the massive "tacit knowledge" bottleneck that must be overcome to train AI for better usability prediction?

Correct Answer: A. The fact that most usability knowledge is trapped inside the heads of experienced professionals or in unstructured recordings, estimated to be 100x more than what is published in guidelines.


The theory posits that while published guidelines (explicit knowledge) are available, the vast majority of usability wisdom exists as tacit knowledge—intuitions and learnings locked inside the minds of UX professionals or buried in unanalyzed video recordings of user sessions. This "dark matter" of UX knowledge is estimated to be 100x larger than the published corpus. To scale AI's usability prediction capabilities, this tacit knowledge must be captured, structured, and fed into the models.


The most likely erroneous answer is A (The high cost of buying hard drives). Storage costs are negligible in the context of AI training. The bottleneck is not the cost of storage but the availability and format of the data (it is unstructured and private), which prevents it from being easily ingested by AI models.



53. In the "AI-First Company" model, what is the role of the "Super-user" compared to the "Auditor"?

Correct Answer: D. The Super-user is a pragmatic tinkerer who refactors workflows and turns messy processes into reliable prompts/policies, while the Auditor is a skeptic who hunts for failure patterns and bias.


These are two critical new roles for managing AI at scale. The Super-user is the internal champion and builder; they figure out how to make the AI work for specific business processes, refactoring workflows to be AI-native. The Auditor plays the opposing role of the safety inspector; they look for drift, hallucinations, bias, and errors, holding the authority to "pull the plug" if the system becomes unsafe or unreliable.


The most likely erroneous answer is A (The Super-user is a customer... Auditor checks finances). This confuses AI-specific operational roles with standard business definitions. In the context of AI-First organizations, "Super-user" and "Auditor" refer specifically to the management and oversight of autonomous AI agents, not general customer segmentation or financial accounting.


⭐ Source: "AI-First Companies" (Sep 11)


54. What concept describes the design leader's shift in "Founder Mode" regarding Product-Market Fit (PMF)?

Correct Answer: B. PMF is redefined internally: the "product" is the design organization's output, and the "market" is the rest of the company that must accept and use it.


In "Founder Mode," design leaders must stop acting like service providers and start acting like owners of the design vision. They must achieve "internal Product-Market Fit." Here, the Product is the design organization itself (its systems, philosophy, and output), and the Market is the internal organization (engineering, product management, executives). The leader's job is to ensure the design organization provides value that the rest of the company "buys" and adopts, aligning the design team's output with the company's strategic needs.


The most likely erroneous answer is C (PMF means finding an external market for the company's design system). While some companies do sell their design systems (like Salesforce Lightning), the "Founder Mode" concept for design leaders is primarily about internal alignment and influence within the enterprise, ensuring the design team isn't sidelined or treated as a mere service bureau.



55. Recently developed AI capabilities allow for "Video-to-Music" transformation. What does this entail?

Correct Answer: C. Using a video clip as a prompt to generate a music track that matches the video's mood and action.


Video-to-Music is a multimodal AI capability (launched by ElevenLabs) where the user uploads a video file, and the AI analyzes the visual content—the pacing, mood, and action—to generate a bespoke music track that fits the video. This automates the role of a film composer or music supervisor for short clips, creating a cohesive audiovisual experience from a visual prompt.


The most likely erroneous answer is A (Converting a music video into a text transcript). This describes transcription or captioning, which are established technologies. The "Video-to-Music" innovation specifically refers to the generative creation of audio based on visual input.



56. What is "Calibrated Trust" in the context of Human-AI collaboration?

Correct Answer: C. The user trusts the AI's capabilities enough to use it, but remains vigilant about its limitations, neither rejecting it due to bias nor accepting errors uncritically.


"Calibrated Trust" is the sweet spot between skepticism and gullibility. Users need enough trust to overcome "algorithm aversion" (refusing to use a helpful tool), but they must avoid "automation bias" (blindly accepting whatever the AI says). It involves understanding what the AI is good at and where it might fail, allowing the user to leverage the AI's speed while applying human judgment to verify critical outputs.


The most likely erroneous answer is A (The user blindly trusts every output). This is over-trust or automation bias, which is dangerous because AI can hallucinate. Calibrated trust explicitly includes vigilance and verification mechanisms; it is about appropriate trust, not total trust.



57. What is the recommended usability best practice for the "Unsubscribe" experience in email newsletters?

Correct Answer: B. Provide a clear "Unsubscribe" link in the footer that works with a single click (or a simple confirmation), and optionally offer an "opt-down" frequency choice.


The best practice focuses on reducing friction. If a user wants to leave, letting them go easily prevents frustration and, crucially, prevents them from marking the email as spam (which hurts deliverability for everyone). A one-click unsubscribe is the gold standard. Offering an "opt-down" (e.g., "Receive fewer emails" or "Weekly digest only") is a good retention strategy to offer alongside the unsubscribe option, but it should never replace the ability to exit completely and instantly.


The most likely erroneous answer is A (Require users to log in). This is a "dark pattern" or high-friction barrier. If users have to remember a password to stop receiving emails they don't want, they will likely give up and use the "Report Spam" button instead, which damages the sender's reputation with email providers.



58. In the "12 Steps for Usability Testing," why are "Post-Session Debriefs" recommended immediately after each test session?

Correct Answer: C. To conduct a "memory dump" with observers while details are fresh, helping the team spot patterns and build shared understanding before formal analysis.


The "Post-Session Debrief" is a critical step for synthesizing qualitative data. Human memory is short; observers will forget specific details or reactions within hours. By gathering the team immediately after a session (for 15 minutes) to discuss what they saw, the team captures fresh insights, identifies recurring patterns early, and builds a shared mental model of the user's struggles. This makes the formal analysis phase faster and more accurate.


In a post-test debriefing, let all observers have their say. In addition to capturing more information, encouraging participation also builds buy-in for later implementation of the findings. (Nano Banana Pro)


The most likely erroneous answer is D (To criticize the participant's performance). This violates the cardinal rule of usability testing: you are testing the design, not the user. Debriefs are for criticizing the product's failure to support the user, never for criticizing the user.

59. In the context of "Think-Time UX," what is the "Background Imperative" (Design Pattern 14) regarding long-running tasks?

Correct Answer: B. Any task taking longer than a few seconds must be backgroundable, allowing the user to multitask without a modal dialog blocking the interface.


The "Background Imperative" dictates that the interface must not be held hostage by the machine’s processing time. If a task takes longer than a few seconds, users naturally want to switch contexts or perform other work while waiting. A system that locks the UI with a modal dialog during such tasks treats the user's time as worthless. Instead, progress indicators should be persistent but unobtrusive (e.g., in a status bar), allowing the user to continue working elsewhere in the application while the long task completes.


The user should be able to turn to other tasks while the computer cranks away in the background. (Seedream 4.5)


The most likely erroneous answer is A (The system should automatically change the background color). This is a literal misinterpretation of the term "background." The pattern refers to the execution state of the process (running in the background vs. blocking the foreground), not the visual styling of the user interface's backdrop.



60. According to the analysis of "Declining ROI From UX Design Work," why has the return on investment for usability projects dropped significantly since the dot-com era?

Correct Answer: C. Because the field has achieved "victory": the low-hanging fruit of terrible design has been picked, and most interfaces now meet a baseline of decent usability, meaning further improvements yield smaller marginal gains.


In the early days of the web (circa 1998), usability was often catastrophic, meaning a small investment in fixing obvious flaws could double or triple conversion rates, yielding astronomical ROI (sometimes 10,000%). Today, thanks to established design patterns and decades of work, most interfaces are "decent." This "UX saturation" means we are now optimizing details rather than fixing broken workflows. While valuable, these incremental improvements cost more to identify and yield smaller comparative returns than the "quick wins" of the past.


The most likely erroneous answer is A (Because user research has become more expensive due to inflation). While costs rise, the fundamental driver of the ROI decline is the diminishing returns on usability improvements, not the input cost of research itself. The source explicitly frames this decline as a sign of the field's success and maturity, not an economic failure of the research methods.

61. In the study of "AI Jobs" by researchers at the University of Oxford, what was the net effect of AI on the job market between 2018 and 2023?

Correct Answer: B. A net positive increase, as the growth in jobs requiring skills complementary to AI (which saw rising wages) outpaced the decline in jobs with skills substitutable by AI.


The study analyzed 12 million job postings and found that AI is creating more opportunity than it destroys. While jobs relying on skills AI can easily substitute (like translation or basic writing) declined, jobs requiring skills that complement AI (like digital literacy and teamwork) grew significantly faster. The result was a net increase in total jobs. Furthermore, the roles with complementary skills saw compensation rise, while those with substitutable skills saw pay drop.


The most likely erroneous answer is A (A net decrease in jobs). This aligns with the common "lump of labor" fear that AI will simply replace humans. However, the empirical data from this large-scale study contradicts that fear, showing that the demand for humans who can work with AI has grown enough to offset the losses in areas where AI works instead of humans.



62. When testing the viability of a UI metaphor, what is the "One-Sentence Test"?

Correct Answer: C. Can you explain the metaphor’s value in one sentence and demonstrate it in one gesture?


The "One-Sentence Test" is a heuristic for evaluating the clarity and utility of a proposed metaphor. If a metaphor is truly effective, its value proposition should be instantly communicable (one sentence) and its interaction model should be immediately graspable (one gesture). If it requires a paragraph of explanation or a complex demo, the metaphor is likely too "cute" or abstract, forcing the user to expend too much cognitive effort to understand the mapping between the real-world source and the digital target.


The most likely erroneous answer is B (Can users describe the interface's function in one sentence). While similar, the specific test defined in the source includes the requirement of a gesture demo ("demo it in one gesture"). This emphasizes the embodied, spatial nature of good metaphors (like "drag to trash") rather than just their verbal description.

63. In the "Form Length Paradox," why do longer forms sometimes achieve higher conversion rates than shorter ones?

Correct Answer: B. Because form completion is a function of the user's motivation versus the perceived friction; if the value of the outcome is high (e.g., a loan application), users accept the friction of a longer form as legitimate.


The relationship between form length and conversion is not linear. While shorter is usually better, users evaluate the legitimacy of the questions relative to the value they get in return. If a user is applying for a high-stakes outcome like a mortgage, a very short form might seem suspicious or unserious. Conversely, if the outcome is low-value (like a newsletter), even a few fields feel like too much friction. High motivation allows users to tolerate the friction of a longer form, provided the fields feel necessary for the transaction.


The most likely erroneous answer is C (Because longer forms appear more authoritative). While "seriousness" is a factor in high-stakes forms, the primary driver is the balance between motivation and friction. Users don't convert because the form is long; they convert despite it being long because their motivation to get the result outweighs the cost of the effort.



64. In the economic analysis of Transformative AI, what does the "Adaptive Buffer" index measure?

Correct Answer: B. The financial and skill-based resilience of workers to withstand displacement by AI, revealing that some high-exposure roles (like programmers) are actually better positioned to adapt than low-exposure roles.


The "Adaptive Buffer" is an economic index designed to measure a worker's capacity to handle the shock of displacement. It includes factors like liquid savings, age, geographic density of jobs, and skill transferability. The research found a counter-intuitive positive correlation: many jobs with high AI exposure (like software developers) also have high adaptive buffers (high savings, transferable skills), meaning these workers are resilient. In contrast, administrative and clerical roles often have high exposure but low buffers, making them the most vulnerable population.


The most likely erroneous answer is A (The amount of memory an AI agent needs). This confuses the concept with technical "buffer memory" in computer science. In the context of the source article on the future of work, the buffer refers to human economic resilience, not machine storage capacity.



65. In the context of "Slow AI" design, what is the purpose of visualizing "Salvage Value"?

Correct Answer: D. To combat the sunk cost fallacy by explicitly showing users what data or artifacts can be saved and reused if they choose to stop a long-running, flawed process mid-stream.


When an AI task runs for hours, users often fall victim to the "sunk cost fallacy"—they hesitate to stop a run that is clearly going wrong because they feel they will lose all the time invested so far. Visualizing "Salvage Value" mitigates this by showing the user that, if they stop now, they can still keep valuable intermediate assets (e.g., "collected dataset" or "partial summary") to use in a future run. This makes the decision to stop and correct course rational and less painful.

The most likely erroneous answer is A (To show users how much money they saved). While cost is a factor in AI, "Salvage Value" in this specific UX pattern refers to retaining data assets from a failed run, not calculating financial savings from using AI versus human labor.


66. Why are "AI-Native" startups, as described by Y Combinator, changing the role of software engineers to "Product Engineers"?

Correct Answer: A. Because AI writes 95% of the code, engineers shift focus to product management duties, overseeing the entire value flow from idea to user experience.


In AI-Native startups, AI tools like vibe coding generate the vast majority of the actual syntax (95%). This frees the human engineer from the minutiae of implementation. Their role consequently expands to cover the "what" and "why" of the software—understanding user needs, defining features, and managing the product's value proposition. They become "Product Engineers," blending the roles of developer and product manager.


The most likely erroneous answer is C (Because they are no longer writing code, but only writing documentation). While they write less code, the shift is not toward documentation (which AI can also do), but toward ownership of the product outcome. The engineer becomes responsible for the user's value, not just the technical output.

67. When deciding between showing an inactive control in a muted color versus hiding it entirely, why is hiding generally considered the worse option?

Correct Answer: B. Because it causes "Context Loss," where users mistakenly conclude a feature doesn't exist or that they are in the wrong place, violating the principle of discoverability.


Hiding controls that are currently unavailable hurts discoverability. If a user expects to find a "Delete" button but doesn't see it, they may think the software lacks that feature or that they are on the wrong screen ("Context Loss"). A visibly disabled (muted) control acts as a placeholder, teaching the user that the feature exists but requires a specific condition to be met (e.g., selecting an item).


The most likely erroneous answer is D (Because it prevents the user from clicking the button to see an error message). While error messages on click are one design pattern (Option 1 in the source), the specific argument against hiding (Option 3) focuses on the loss of awareness and mental modeling regarding the system's capabilities, rather than the lack of error feedback.



68. In the categorization of Prompt Augmentation features, what distinguishes "Intent Clarification" features?

Correct Answer: B. They serve as translators when the original prompt is unclear or incomplete, helping users better express their true goal (e.g., Prompt Expansion).


"Intent Clarification" features are designed to bridge the gap between a user's vague initial input and the detailed instructions an AI needs. They act as translators: if a user types a simple request, the system expands or refines it to better match the user's likely (but unstated) goal. This lowers the articulation barrier by reducing the precision required from the user in the first step.


The most likely erroneous answer is C (They allow users to select from a gallery of images). This describes "Style Galleries" or "Multimodal Input Features." Intent clarification is specifically about refining the meaning and structure of the prompt itself, usually through text expansion or refinement, rather than visual selection.



69. In the "Mammoth Hunter" analogy for the AI career transition, what does the "Mammoth Hunter" represent?

Correct Answer: B. The legacy UX professional who excels at handcrafted, pre-AI skills (like manual wireframing), which are becoming irrelevant in the new "farming" era of AI abundance.


The analogy compares the transition to AI with the transition from hunting-gathering to agriculture. The "Mammoth Hunter" is the expert at the old way of doing things (legacy UX skills). While highly skilled and respected in the old world, their skills (hunting) are rendered obsolete by the new paradigm (farming/AI). Becoming the "best apprentice mammoth hunter" is a bad career move when the world is switching to farming; similarly, learning manual UX skills is a bad move when AI is taking over execution.


Being the apprentice to the tribe’s best mammoth hunter is a bad career move if agriculture has just been introduced. (Nano Banana Pro)


The most likely erroneous answer is A (The new AI agent that hunts for data). The mammoth hunter represents the human professional clinging to obsolete methods, not the AI tool. The AI represents the new environment (agriculture) that changes the value of human labor.



90. As traditional user interfaces dissolve into AI agents, the discipline of UX design is predicted to morph into something most resembling which existing field?

Correct Answer: A. Service Design: mapping actors, backstage processes, and front-stage touchpoints to ensure coherence even when the "plumbing" is invisible.


As visual UIs (screens) are replaced by AI agents that handle tasks autonomously, the designer's role shifts from crafting visual affordances to orchestrating "systems of intent." This resembles Service Design, which focuses on the holistic coordination of people, infrastructure, and processes (the "backstage") to deliver a service, rather than just the visual touchpoint. The work becomes about designing policies, guardrails, and handoffs rather than pixel-perfect layouts.


The most likely erroneous answer is B (Graphic Design). This is the opposite of the trend. As the UI disappears ("No UI"), graphic design becomes less central to the core interaction, while the structural and systemic aspects (Service Design) become dominant.
