Marketers have long recognized that perceived scarcity, the sense that a product or opportunity ①are available only in limited quantity or for a limited time, can dramatically increase its desirability, even when the item's intrinsic qualities remain entirely unchanged. This phenomenon, known as the scarcity effect, operates on a simple psychological principle: when something appears difficult to obtain, people tend ②to infer that it must be valuable, since truly worthless items rarely generate genuine competition for possession. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer exploits this inference, ③prompting customers to make hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products ④are rated as more desirable and often command higher prices when framed as scarce than when the same products are presented as widely and continuously available. The effect intensifies further when scarcity is attributed to high demand rather than to limited supply alone, since competition from other buyers ⑤introduces an additional layer of urgency absent from mere supply constraints.

Among the many tools available to those who design choice environments, few are as quietly powerful as the default option, the alternative that ①takes effect automatically unless a person actively selects something else. Because changing a default requires deliberate effort, many individuals simply accept whatever arrangement has been preselected for them, regardless of whether that arrangement actually ②serve their interests best. This tendency has been documented across a remarkably wide range of contexts. Countries that automatically enroll citizens in organ donation programs, requiring an explicit request to opt out, consistently report far higher donor registration rates than countries that require citizens ③to actively opt in. Employers who automatically enroll new hires in retirement savings plans likewise see participation rates ④climb dramatically compared with employers who leave enrollment entirely voluntary. What makes default options so influential is not merely convenience; a default also functions as an implicit signal about what is considered normal or recommended, subtly ⑤shaping perceptions even among individuals who believe themselves to be deciding independently.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, allowing paralyzed patients to control a robotic arm or type a message using thought alone. As the technology ①improves, some developers envision a future in which brain-computer interfaces extend beyond restoring lost function toward enhancing healthy minds. This prospect raises a philosophical question that medicine alone cannot answer: if a device can alter memory, mood, or decision-making, at what point does the assistance stop being a tool and start ②reshaping the very identity of the person using it. Neuroethicists argue that mental privacy, the ability to keep one's own thoughts ③exposed to external access or manipulation, may need to be recognized as a fundamental right before this technology becomes ④widespread. This concern is likely to grow ⑤more urgent as the devices become more powerful.

A few years ago, spotting a manipulated video required a trained eye and ①specialized software. Today, freely available applications allow almost anyone to swap a face or fabricate a voice ②convincingly enough to fool casual viewers within minutes. This shift has quietly ③reinforced one of the oldest assumptions in human communication: that seeing and hearing something is a reasonably reliable way to confirm it happened. Journalists now face the burden of verifying footage that once would have been accepted as ④self-evident proof. Perhaps more troubling than any single fake video is the broader effect on public trust, in which genuine footage can be ⑤dismissed as fabricated simply because deepfakes exist.

When individuals face uncertainty about how to behave, they frequently look to the actions of others for guidance. This reliance on collective behavior can be remarkably ①efficient, since it allows individuals to benefit from the accumulated judgment of a crowd without having to gather and evaluate every relevant fact themselves. However, social proof can also lead entire groups astray when the initial signal that triggers imitation is itself ②unreliable or coincidental. A restaurant that happens to attract a long line early in the evening may continue attracting customers throughout the night simply because passersby interpret the queue as evidence of ③inferior quality. Financial markets exhibit an analogous pattern: investors who observe others buying a particular asset often join the buying themselves, reasoning that so many participants cannot all be mistaken, a dynamic that can ④inflate prices well beyond any reasonable estimate of underlying value. Because conformity can substitute for independent judgment so ⑤seamlessly, individuals rarely notice when their own decisions have become mere imitations rather than genuinely deliberated.

Financial markets occasionally experience episodes in which asset prices rise far beyond any level that careful analysis of underlying fundamentals could justify, a phenomenon commonly attributed to herd psychology. During such episodes, individual investors often conclude that continuing to buy is reasonable simply because so many others are doing the same, rather than because any independent evaluation supports the purchase. Understanding market bubbles thus requires looking beyond conventional economic fundamentals toward the ___________ that binds individual investors into a single, momentum-driven crowd.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. (A) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed much faster. (B) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. (C) A factory worker displaced this year, therefore, cannot simply wait for a new industry to emerge decades from now.

주어진 문장: As a result, the combined effect of heat-absorbing surfaces and limited greenery can raise nighttime temperatures in cities by several additional degrees. Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known as the urban heat island effect, which intensifies in summer and threatens public health. ① This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, preventing urban areas from cooling down. ② Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. ③ To address this problem, urban planners have begun implementing mitigation strategies designed to lower surface and air temperatures. ④ One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. ⑤ In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. ① ② ③ ④ ⑤

Yet this reluctance to accept a small certain loss often leads to a much larger loss later, when the declining trend continues unabated. Loss aversion strongly influences how investors manage their portfolios during periods of market decline. ( ① ) When the value of a stock begins to fall, many investors postpone selling, hoping that the price will rebound to its original level. ( ② ) This tendency is closely tied to the psychological discomfort of converting an unrealized loss into a realized one, since selling forces the investor to formally acknowledge the loss. ( ③ ) Research on trading behavior consistently shows that investors hold declining stocks for longer periods than rising ones, a pattern that runs counter to the basic principle of cutting losses early. ( ④ ) Financial advisors therefore encourage clients to set predetermined selling thresholds in advance, before emotional attachment to a particular price can distort their judgment. ( ⑤ ) By committing to a rule beforehand, investors can partially neutralize the emotional bias that loss aversion introduces into decision-making.

This evidentiary standard, ironically, has made behavioral interventions more rigorously tested than many of the traditional programs they were designed to complement. Government adoption of behavioral insights has generally been governed by a strict evidentiary standard: officials demand proof that a proposed intervention works before authorizing its use. ( ① ) This demand led to the routine use of randomized controlled trials, in which a proposed change is tested on a small population before being rolled out more broadly. ( ② ) Such trials allow policymakers to determine with reasonable confidence whether an intervention produces the intended effect before committing significant public resources to it. ( ③ ) Many long-standing government programs, by contrast, were implemented decades ago without ever being subjected to comparably rigorous evaluation. ( ④ ) Behavioral units within government have, as a result, gradually earned a reputation for evidence-based rigor that extends well beyond their original, narrow mandate. ( ⑤ ) That reputation has, in turn, given behavioral approaches an outsized voice in policy discussions relative to their still-modest budgets.
