Question 1

1. Mental set: sticking to a familiar strategy because it worked before, even when it is ineffective in a new context. (correct answer)
2. Confirmation bias: searching only for information that supports a belief while ignoring contradictory evidence.
3. Availability heuristic: basing judgments on easily recalled examples rather than on careful evaluation of evidence.
4. Anchoring bias: relying too heavily on an initial number when making later estimates or predictions.

Explanation: Mental set is the tendency to stick with a familiar problem-solving strategy because it worked successfully in previous situations, even when it becomes ineffective or inefficient in a new context that requires different approaches. This differs from confirmation bias (selective information processing), availability heuristic (ease of recall), and anchoring bias (initial information influence). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts for decision-making, but mental set specifically involves inflexible strategy persistence. While familiar approaches can be efficient, mental set prevents adaptation when circumstances change. The student's continued use of history class note-taking methods in calculus, despite it hurting understanding, demonstrates mental set - persistence with a previously successful strategy that's inappropriate for the new context.

Question 2

1. Heuristic: a quick mental shortcut that speeds decisions but may sometimes produce errors under uncertainty or time pressure.
2. Algorithm: a systematic, step-by-step procedure that, when followed correctly, guarantees a solution to the problem. (correct answer)
3. Insight: a sudden, novel realization that restructures the problem and produces an "aha" solution without stepwise trial.
4. Availability heuristic: judging likelihood based on how easily examples come to mind, often influenced by vivid or recent events.

Explanation: Problem-solving strategies fall into two main categories: algorithms and heuristics. An algorithm is a systematic, step-by-step procedure that guarantees a correct solution when followed properly, like following a recipe exactly. Heuristics are mental shortcuts that speed up decision-making but may sometimes produce errors. The three main heuristics are availability (judging likelihood by how easily examples come to mind), representativeness (judging probability by similarity to prototypes), and anchoring (being overly influenced by initial information). While heuristics can lead to cognitive biases, they are adaptive tools that allow efficient decision-making under uncertainty. In this case, following a recipe step-by-step guarantees the correct cake every time, making it a clear example of an algorithm.

Question 3

1. Framing effect: decisions change depending on whether the same outcome is described as a gain or as a loss.
2. Hindsight bias: viewing past events as more predictable than they were once the outcome is known. (correct answer)
3. Anchoring bias: letting an initial number dominate later estimates, even when the anchor is arbitrary or irrelevant.
4. Mental set: repeating a previously effective strategy even when it no longer fits the problem's requirements.

Explanation: Hindsight bias, also known as the "knew-it-all-along" effect, occurs when people believe they predicted an outcome after learning what actually happened, overestimating their prior certainty. This differs from the framing effect (how information presentation affects decisions), anchoring bias (over-reliance on initial information), and mental set (persistence with familiar strategies). The three main heuristics - availability, representativeness, and anchoring - are generally adaptive but can lead to various biases. Hindsight bias is particularly problematic because it can lead to overconfidence in future predictions. Omar's claim that he knew the election winner all along, despite earlier uncertainty, demonstrates classic hindsight bias.

Question 4

1. Availability heuristic: estimating frequency based on how easily examples come to mind, amplified by repeated vivid exposure. (correct answer)
2. Anchoring bias: relying too heavily on the first burglary statistic seen and adjusting insufficiently afterward.
3. Mental set: using an old home-security strategy even when new threats require a different approach.
4. Insight: a sudden "aha" realization about crime rates that appears without any evidence or information.

Explanation: The availability heuristic involves estimating frequency or likelihood based on how easily examples come to mind, which can be amplified by repeated vivid exposure through media or personal experience. This differs from anchoring bias (initial information influence), mental set (strategy persistence), and insight (sudden understanding). The three main heuristics - availability, representativeness, and anchoring - are generally adaptive tools for decision-making under uncertainty, but they can lead to systematic biases when memorable examples don't reflect actual statistical patterns. Media exposure can particularly distort availability-based judgments. The homeowner's belief that burglaries are extremely common after watching many burglary videos demonstrates the availability heuristic, as the repeated vivid exposure makes burglary examples highly accessible in memory.

Question 5

1. Representativeness heuristic: judging probability by stereotype match while neglecting base rates and actual prevalence. (correct answer)
2. Availability heuristic: estimating likelihood from recall ease, especially after recent news about firefighters.
3. Anchoring bias: overreliance on an initial number, adjusting insufficiently when learning more information.
4. Algorithm: using a guaranteed sequence of steps that always identifies occupations correctly from appearance alone.

Explanation: The representativeness heuristic involves judging probability based on how well someone matches a stereotype or prototype while neglecting important statistical information like base rates and actual prevalence in the population. This differs from availability heuristic (ease of recall), anchoring bias (initial information influence), and algorithms (systematic procedures). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that can be adaptive for quick decision-making but may lead to systematic errors when stereotypical thinking overrides statistical reasoning. Base-rate neglect is a common consequence of representativeness heuristic. The student's assumption that a muscular, brave person is a firefighter, while ignoring that firefighters are actually quite rare in the population, demonstrates representativeness heuristic with base-rate neglect.

Question 6

1. Anchoring bias: an initial value strongly influences later judgments, and adjustments for new information are too small. (correct answer)
2. Availability heuristic: judging the grade based on which class moments are easiest to recall, not on scores.
3. Representativeness heuristic: assuming the grade will match a "typical student" stereotype rather than actual performance.
4. Hindsight bias: after receiving the final grade, believing you predicted it accurately all along.

Explanation: Anchoring bias occurs when initial information acts as a reference point that strongly influences later judgments, with people typically making insufficient adjustments even when they receive additional relevant information that should change their estimates. This differs from availability heuristic (ease of recall), representativeness heuristic (prototype matching), and hindsight bias (believing you predicted outcomes). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts for decision-making under uncertainty, but anchoring can lead to systematic errors when initial information unduly constrains later thinking. The student's grade prediction based heavily on their first quiz score, with only slight adjustments despite later higher scores, demonstrates classic anchoring bias.

Question 7

1. Insight: a sudden restructuring of the problem that produces an "aha" solution rather than gradual trial-and-error steps. (correct answer)
2. Algorithm: a guaranteed, systematic procedure that solves the problem if all steps are followed correctly each time.
3. Availability heuristic: relying on easily recalled examples to judge likelihood, which can distort risk estimates.
4. Only negativity: assuming shortcuts are always irrational and therefore refusing to use any quick decision strategies.

Explanation: Insight is a sudden reorganization or restructuring of a problem that leads to an "aha!" moment and immediate understanding of the solution, without gradual trial-and-error steps. This contrasts with algorithms (systematic step-by-step procedures) and heuristics like availability (ease of recall). While heuristics are mental shortcuts that can be adaptive for quick decision-making under uncertainty, insight represents a different type of problem-solving that involves creative restructuring. The three main heuristics are availability, representativeness, and anchoring, but insight operates through a different cognitive mechanism. The student's sudden realization that adding an auxiliary line solves the geometry proof represents classic insight problem-solving.

Question 8

1. Functional fixedness: difficulty perceiving an object's alternative uses beyond its typical function, limiting creative solutions. (correct answer)
2. Anchoring bias: overreliance on an initial value that skews later judgments, even when the anchor is unrelated.
3. Confirmation bias: focusing on evidence that supports an existing belief while discounting information that challenges it.
4. Algorithm: a stepwise method that guarantees a correct solution, but requires time and careful execution.

Explanation: Functional fixedness is the inability to see new uses for familiar objects beyond their typical function, which can block creative problem-solving. This cognitive obstacle differs from anchoring bias (over-reliance on initial numbers), confirmation bias (selective information processing), and algorithms (systematic procedures). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that can be adaptive but sometimes lead to errors. Functional fixedness specifically limits creative thinking by constraining how we perceive objects. Talia's inability to imagine using a coin as a screwdriver demonstrates functional fixedness because she can only see the coin in its conventional role as money, not as a potential tool.

Question 9

1. Anchoring bias: the initial rating becomes a reference point, and later information shifts judgment only slightly. (correct answer)
2. Hindsight bias: after eating there, believing the experience was predictable and you "knew it all along."
3. Framing effect: changing evaluation depending on whether reviews emphasize positives or negatives, despite equal content.
4. Mental set: using a previously successful approach to choose restaurants even when the context is different.

Explanation: Anchoring bias occurs when initial information becomes a reference point that strongly influences later judgments, with people typically making insufficient adjustments even when they receive additional relevant information. This differs from hindsight bias (believing you predicted outcomes), framing effect (presentation influence), and mental set (strategy persistence). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that can be adaptive for quick decision-making but may lead to systematic errors. Anchoring is particularly powerful because first impressions or initial values continue to influence thinking even when contradicted by later evidence. The person's insistence that their first impression of a restaurant rating is correct, despite reading many newer reviews, demonstrates anchoring bias.

Question 10

1. Mental set: tendency to stick with a previously successful problem‑solving method, even when a new strategy is better. (correct answer)
2. Availability heuristic: estimating likelihood from how easily examples come to mind, especially vivid or recent cases.
3. Representativeness heuristic: judging probability by similarity to a prototype, often overlooking base rates and true frequencies.
4. Algorithm: a method that always guarantees the correct solution, but is typically slower than shortcuts.

Explanation: Mental set is the tendency to persist with a previously successful problem-solving approach, even when the current situation would benefit from a different strategy. This differs from the three main heuristics: availability (ease of recall), representativeness (prototype matching), and anchoring (initial information influence). While algorithms guarantee correct solutions, they can be time-consuming. Mental set can be problematic because it prevents flexible thinking and adaptation to new circumstances, though familiar strategies can sometimes be efficient. The physician's preference for a familiar treatment plan, despite new evidence supporting different approaches, demonstrates mental set - sticking with what worked before rather than adapting to new information.

Question 11

1. Availability heuristic: judging risk by how easily vivid images or examples come to mind, not by actual statistics. (correct answer)
2. Representativeness heuristic: judging probability by prototype match, ignoring base-rate safety data and frequencies.
3. Algorithm: using a guaranteed step-by-step process that always yields an accurate risk perception.
4. Functional fixedness: inability to see alternative uses for objects, limiting creative solutions to travel planning.

Explanation: The availability heuristic involves judging risk or likelihood based on how easily vivid examples or images come to mind, rather than on actual statistical data or objective risk assessments. This differs from representativeness heuristic (prototype matching), algorithms (systematic procedures), and functional fixedness (limited object perception). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts for decision-making under uncertainty, but they can lead to systematic biases when memorable examples don't reflect true statistical patterns. Vivid, dramatic scenarios often have disproportionate influence on risk perception. The person's decision that a plane is unsafe because they can vividly imagine a crash, despite knowing low accident rates, demonstrates the availability heuristic overriding statistical reasoning.

Question 12

1. Algorithm: a systematic procedure that exhaustively searches possibilities and guarantees a correct solution if applied correctly. (correct answer)
2. Availability heuristic: choosing an answer because it is easy to recall, especially if it appeared recently.
3. Insight: a sudden restructuring of the clue that yields an immediate "aha" answer without stepwise testing.
4. Only negativity: rejecting systematic methods because they are slow, assuming speed is always better than accuracy.

Explanation: An algorithm is a systematic, step-by-step procedure that guarantees finding the correct solution when applied properly, though it may be time-consuming compared to mental shortcuts. This differs from heuristics like availability (ease of recall) and insight (sudden understanding). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that can be adaptive for quick decision-making under uncertainty, but they don't guarantee correct solutions like algorithms do. While heuristics can sometimes lead to cognitive biases, algorithms provide reliable but often slower problem-solving approaches. The systematic testing of every possible letter combination until finding the correct crossword answer represents an algorithmic approach because it exhaustively searches all possibilities and guarantees success.

Question 13

1. Representativeness heuristic: judging likelihood by how well someone matches a stereotype or prototype, not the evidence. (correct answer)
2. Availability heuristic: estimating probability based on how easily examples are recalled, especially vivid media stories.
3. Algorithm: applying a guaranteed set of logical steps that always yields the correct verdict when followed.
4. Framing effect: choosing differently when the same outcomes are described as gains versus losses.

Explanation: The representativeness heuristic involves judging probability based on how closely someone or something matches a typical example or stereotype, often while ignoring important statistical information like base rates. This differs from the availability heuristic (ease of recall), algorithms (systematic procedures), and the framing effect (presentation influence). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that can be adaptive for quick decision-making but sometimes lead to biases. Representativeness can be problematic when stereotypical thinking overrides evidence-based reasoning. The juror's assumption that the defendant "looks like a criminal" and therefore must be guilty demonstrates representativeness heuristic, as they're matching the person to a criminal stereotype rather than evaluating the actual evidence.

Question 14

1. Availability heuristic: judging frequency, importance, or value based on how readily examples come to mind. (correct answer)
2. Representativeness heuristic: judging probability by similarity to a prototype while ignoring base-rate information.
3. Algorithm: a guaranteed procedure that will always select the objectively best college if followed carefully.
4. Mental set: persisting with an old strategy for choosing schools even when circumstances require a new approach.

Explanation: The availability heuristic involves judging frequency, probability, or importance based on how easily examples come to mind, often influenced by vividness, recency, or emotional impact. This differs from representativeness heuristic (prototype matching), algorithms (systematic procedures), and mental set (strategy persistence). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts that speed decision-making under uncertainty, though they can sometimes lead to biased judgments. The availability heuristic can be problematic when memorable examples don't reflect actual statistical frequencies. The student's college choice based on easily recalled famous alumni demonstrates the availability heuristic, as the ease of recalling these examples influences their perception of the school's quality.

Question 15

1. Framing effect: equivalent information produces different judgments when presented in positive versus negative terms. (correct answer)
2. Anchoring bias: the first number seen becomes a reference point that skews later judgments and estimates.
3. Hindsight bias: after purchase, believing you knew the health value all along and it was obvious.
4. Mental set: applying a previously successful shopping method even when nutrition labels require new evaluation.

Explanation: The framing effect occurs when equivalent information produces different judgments depending on whether it's presented in positive versus negative terms, even when the objective content is identical. This differs from anchoring bias (initial information influence), hindsight bias (believing you predicted outcomes), and mental set (strategy persistence). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts, but the framing effect specifically demonstrates how presentation format systematically influences decision-making. This effect reveals that human judgment is sensitive to linguistic framing, not just factual content. The shopper's perception that "95% fat-free" is healthier than "contains 5% fat," despite the identical nutritional content, demonstrates the framing effect.

Question 16

1. Algorithm: a methodical rule-based procedure that, when followed correctly, guarantees an accurate solution to the problem. (correct answer)
2. Heuristic: a fast shortcut that guarantees correctness but is slower than a full algorithmic approach.
3. Mental set: sticking with a familiar strategy even when it fails, preventing flexible problem solving.
4. Availability heuristic: judging the best answer by what is easiest to recall rather than by logical constraints.

Explanation: An algorithm is a methodical, rule-based procedure that, when followed correctly step-by-step, guarantees an accurate solution to a problem, though it may be more time-consuming than heuristic shortcuts. This differs from heuristics (which are fast but not guaranteed), mental set (strategy persistence), and availability heuristic (ease of recall). The three main heuristics - availability, representativeness, and anchoring - are adaptive mental shortcuts for decision-making under uncertainty but don't provide the guarantee of correctness that algorithms offer. While heuristics can sometimes lead to cognitive biases, algorithms provide systematic reliability. The student's use of a guaranteed set of logical rules to solve a puzzle represents an algorithmic approach because it follows a predetermined method that ensures correct solutions.

Question 17

1. Confirmation bias: prioritizing information that supports an expectation and discounting evidence that contradicts it. (correct answer)
2. Framing effect: changing decisions based on gain-versus-loss wording, even when outcomes are objectively identical.
3. Availability heuristic: basing judgments on what comes to mind quickly, especially vivid or recent examples.
4. Insight: a sudden restructuring of the problem that generates an "aha" solution without incremental reasoning.

Explanation: Confirmation bias involves prioritizing information that supports existing expectations or beliefs while discounting or dismissing evidence that contradicts those expectations, leading to biased information processing. This differs from framing effect (presentation influence), availability heuristic (ease of recall), and insight (sudden understanding). The three main heuristics - availability, representativeness, and anchoring - are generally adaptive mental shortcuts, but confirmation bias specifically involves selective attention to supporting evidence. This bias can severely impede objective analysis and learning, particularly in academic and scientific contexts where evidence evaluation is crucial. The student's rejection of a correct solution because it differs from their expectations, followed by searching for supporting evidence, demonstrates confirmation bias.

Question 18

1. Confirmation bias: selectively attending to or seeking information that supports existing beliefs while minimizing disconfirming evidence. (correct answer)
2. Hindsight bias: after learning an outcome, believing you "knew it all along" and overestimating prior prediction accuracy.
3. Availability heuristic: judging likelihood by ease of recall, especially for vivid examples, rather than by actual statistics.
4. Functional fixedness: inability to see alternative uses for objects, preventing creative solutions to practical problems.

Explanation: Confirmation bias is the tendency to search for, interpret, and recall information in ways that confirm pre-existing beliefs while giving disproportionately less consideration to alternative possibilities. This differs from hindsight bias (believing you predicted outcomes after knowing results) and the availability heuristic (judging likelihood by ease of recall). Functional fixedness involves difficulty seeing alternative uses for objects. While heuristics can be adaptive shortcuts, confirmation bias specifically involves selective information processing. Nia's behavior of reading only positive reviews about her preferred phone brand while ignoring negative reports is a clear example of confirmation bias, as she's selectively seeking information that supports her existing preference.

Question 19

1. Availability heuristic: estimating frequency or risk based on how quickly relevant examples are retrieved from memory. (correct answer)
2. Representativeness heuristic: judging probability by how closely something matches a prototype, often ignoring base-rate information.
3. Algorithm: a systematic set of steps that guarantees the correct answer, though it may take considerable time.
4. Functional fixedness: difficulty seeing alternative uses for objects, which blocks creative problem solving in novel tasks.

Explanation: The availability heuristic is a mental shortcut where people estimate the frequency or likelihood of events based on how easily examples come to mind. This heuristic can be influenced by vivid, recent, or emotionally charged examples that are more memorable. The representativeness heuristic involves judging probability by similarity to prototypes, while anchoring involves over-relying on initial information. These heuristics are generally adaptive but can lead to systematic biases. Maya's overestimation of beach danger occurs because shark attack stories from news are vivid and easily recalled, making them seem more frequent than they actually are, which is the classic pattern of the availability heuristic.

Question 20

1. Algorithm: a structured, step-by-step decision procedure that systematically narrows possibilities and can ensure correct diagnosis. (correct answer)
2. Availability heuristic: choosing the cause that comes to mind first because it happened recently, not because it fits evidence.
3. Insight: a sudden "aha" realization of the cause without testing steps or evaluating alternatives.
4. Functional fixedness: inability to see alternative uses for tools, preventing troubleshooting from progressing.

Explanation: An algorithm is a structured, systematic procedure that follows predetermined steps to solve problems, guaranteeing correct solutions when properly executed, though it may be slower than heuristic approaches. This differs from availability heuristic (ease of recall), insight (sudden understanding), and functional fixedness (limited object perception). The three main heuristics - availability, representativeness, and anchoring - are mental shortcuts that speed decision-making under uncertainty but don't guarantee accuracy like algorithms do. While heuristics can be adaptive and efficient, algorithms provide reliability and systematic problem-solving. Using a diagnostic flowchart that systematically checks each condition in order until finding the computer issue's cause represents an algorithmic approach because it follows a predetermined sequence that ensures comprehensive problem-solving.
