A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market ①do exactly that under the right conditions. Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are ②synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities ③that reach conditions rarely found in a backyard compost heap or the open ocean. Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, ④complicating the assumption that a biological origin automatically makes a material more sustainable. Researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops, hoping to ⑤sidestepping this competition for land while preserving the benefits that first made bioplastics appealing.

Conventional economic wisdom holds that more options are always preferable to fewer, since a larger set of alternatives increases the likelihood that any individual will find one that precisely ①matches their preferences. Empirical research on consumer behavior, however, complicates this assumption considerably. When shoppers are presented with an extensive array of choices, they frequently experience heightened anxiety about making the wrong selection and, paradoxically, ②become less likely to make any purchase or decision at all. This phenomenon, commonly ③called choice overload, arises because evaluating numerous alternatives demands considerable cognitive effort, and the fear of forgoing a superior but unexamined option can overwhelm the pleasure of selecting from a limited set. Furthermore, individuals who do eventually choose from an overwhelming array often ④reports lower satisfaction with their selection than those who chose from a modest handful of options. Businesses that recognize this dynamic have begun deliberately ⑤curating smaller, carefully selected assortments.

Classical economic models typically assume that people discount future rewards at a constant rate, ①valuing a reward received later somewhat less than an identical reward received now. Empirical observation, however, reveals a different pattern: people apply a much steeper discount to the immediate future than to the distant future, a phenomenon ②termed hyperbolic discounting. This inconsistency explains why an individual might sincerely resolve tonight to wake up early and exercise tomorrow, only to postpone the plan once tomorrow actually arrives and the immediate discomfort of getting out of bed ③become vivid and present. When the reward or cost in question lies safely in the future, its emotional weight remains muted, ④allowing rational long-term goals to dominate one's stated intentions. Once that same reward or cost draws near, however, its immediacy triggers a disproportionately strong emotional pull, frequently ⑤overriding the very plans made earlier with such apparent confidence.

Policymakers seeking to improve public welfare without restricting individual freedom have increasingly embraced an approach known as nudging, which alters the environment in which choices are made rather than mandating particular outcomes. A nudge preserves every option that was previously available; it simply arranges those options so that the choice deemed most beneficial becomes easier or more visible than the alternatives. Despite ongoing debate over its ethics, governments across many countries have adopted nudge-based programs, reporting outcomes that are frequently ___________ compared with those achieved through traditional regulation or public information campaigns alone.

The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases. (A) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. (B) Yet editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation. (C) Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

Confirmation bias becomes particularly consequential in political discourse, where citizens must evaluate competing claims about complex issues. (A) As a result, exposure to more information does not necessarily produce more accurate beliefs; it can instead deepen existing divisions by giving each side additional material that appears to validate its own position. (B) Voters who favor a particular policy tend to seek out news sources and commentators who share that view, while largely avoiding those who might challenge it. (C) This selective consumption means that two people examining ostensibly the same news environment can end up with radically different, mutually reinforcing interpretations of events.

주어진 문장: This shows that expertise alone does not guarantee immunity from such intuitive shortcuts. Suppose you meet a quiet, gentle man who speaks softly, tends a small garden, and organizes his bookshelf with meticulous care. ( ① ) Asked whether he is more likely a florist or a truck driver, most people instinctively choose florist, since his personality matches the stereotype so neatly. ( ② ) This judgment, however, ignores a crucial fact: truck drivers vastly outnumber florists in almost every country, which means that, statistically, he is far more likely to belong to the larger group regardless of how well he fits the flower-shop image. ( ③ ) Relying on resemblance to a familiar category rather than on underlying numerical proportions, known among researchers as representativeness, leads people to overlook these base rates almost automatically. ( ④ ) Even trained professionals, who should know better, often fall into the same trap when a vivid description feels more convincing than plain statistics. ( ⑤ ) Consequently, teaching people to pause and ask how common something actually is, instead of merely how typical it appears, can meaningfully improve the accuracy of everyday predictions and reduce costly errors in judgment.

This finding is particularly striking given that the two groups of employees faced no difference whatsoever in the financial terms of the plan itself. Employers have long experimented with how retirement savings plans are presented to new hires. ( ① ) In one common arrangement, employees receive a form and must actively check a box to begin contributing a portion of their salary to a savings account. ( ② ) Under this opt-in arrangement, a substantial share of eligible employees never get around to enrolling, often citing simple procrastination rather than genuine disinterest in saving. ( ③ ) When employers instead enroll employees automatically and require them to check a box only if they wish to withdraw, participation rates climb to well over ninety percent. ( ④ ) Only the framing of the choice, not its economic substance, appears to determine whether employees end up saving for retirement. ( ⑤ ) This gap between the two arrangements reveals just how powerfully a default setting can shape decisions that people generally regard as carefully considered.

None of these individual passersby, however, has any direct evidence that the food itself is worth the wait. Consider how a line forms outside a small restaurant on an otherwise quiet street. ( ① ) The first few patrons may have arrived simply because of a personal recommendation or a delayed reservation, factors entirely unrelated to the restaurant's actual quality. ( ② ) As the line grows, passersby begin to notice it and, assuming that such popularity must be earned, decide to join the queue themselves. ( ③ ) Each additional person who joins makes the line appear even more compelling to the next passerby, creating a self-reinforcing cycle of imitation. ( ④ ) They are, in effect, relying entirely on the visible behavior of strangers as a proxy for information they do not personally possess. ( ⑤ ) The restaurant's true culinary merit, whatever it may be, has become almost irrelevant to the continued growth of the line.

Consequently, even seasoned professionals who believe themselves immune to such influence often fail to notice how much their final judgment has shifted. The anchoring effect can be surprisingly resistant to conscious correction. ( ① ) Even when individuals are explicitly warned in advance that a number they are about to see is randomly generated and therefore meaningless, their subsequent estimates still drift toward that arbitrary figure. ( ② ) This occurs because the mind uses the initial number as a starting point and then adjusts insufficiently away from it, a process that leaves the final judgment biased toward the anchor. ( ③ ) Experimental studies have repeatedly demonstrated this effect across a wide range of tasks, from estimating historical dates to appraising real estate. ( ④ ) The bias persists not because people lack expertise, but because the adjustment process itself is inherently incomplete. ( ⑤ ) Awareness of the anchoring effect, therefore, does not guarantee immunity from it, which is precisely what makes the bias so difficult to counteract in practice.
