A striking proportion of individual investors believe their own stock-picking ability to be above average, a statistical impossibility given that only half of any population can genuinely outperform the rest, yet a pattern that ①persists with remarkable consistency across surveys. This tendency, known as overconfidence bias, leads investors ②to trade more frequently than a more cautious assessment of their own skill would justify. Extensive research comparing the trading records of numerous individual accounts has demonstrated that investors who trade most frequently ③tends to earn substantially lower returns than those who trade rarely, largely because transaction costs accumulate and because frequent trading often reflects overconfident reactions to short-term noise rather than genuine insight. Overconfidence also manifests in the tendency to underestimate the range of possible outcomes, ④causing investors to concentrate their holdings in a small number of assets they feel certain about rather than diversifying across a broader portfolio. Paradoxically, then, the very confidence that motivates investors to act decisively often ⑤undermines the outcomes they are trying to achieve.

Identical information can provoke strikingly different reactions depending on how it ①is worded, a phenomenon economists call the framing effect. Patients told that a surgical procedure carries a ninety percent survival rate tend to consent to it far more readily than patients ②told that the same procedure carries a ten percent mortality rate, even though the two descriptions convey exactly the same statistical reality. This discrepancy arises because language does more than transmit facts; it also supplies an emotional lens through which those facts ③interpreting. Positive framing, which emphasizes what will be preserved or gained, tends to encourage risk-averse choices, whereas negative framing, which emphasizes what might be lost, often ④pushes people toward riskier alternatives in an attempt to avoid the loss altogether. Recognizing how deeply framing shapes judgment is therefore essential, not because the underlying facts change, but because the very same facts, ⑤dressed in different language, can lead reasonable people toward entirely opposite conclusions.

People often recognize, in calm reflection, that their future selves will be tempted to ①abandoning a goal they currently value. Rather than relying solely on willpower at the critical moment, they may choose to restrict their own future options in advance, a strategy ②known as precommitment. By making certain choices costly, inconvenient, or impossible to reverse, individuals can protect a long-term goal from a short-term impulse that has not yet ③arisen. A person hoping to save money might lock funds into an account that penalizes early withdrawal, removing the very temptation that would otherwise be difficult to ④resist. Similarly, someone ⑤determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken.

As solar and wind power expand rapidly across national grids, engineers face a challenge that ①receive far less public attention than the construction of the generating facilities themselves. Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, ②producing supply that fluctuates constantly. One proposed solution involves large-scale battery storage systems, ③which absorb surplus electricity generated during periods of high output and release it later when generation declines. Grid operators must therefore invest in infrastructure capable of ④accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are ⑤expected to provide.

When people recall precisely where they were and what they were doing at the moment they learned of some momentous public event, the resulting memory often feels extraordinarily vivid, as though it had been etched into the mind with photographic precision; researchers have termed such recollections flashbulb memories. Proponents of this concept once argued that the emotional intensity and surprise accompanying such events trigger a distinct neural mechanism that preserves details with unusual fidelity, effectively exempting them from the gradual decay that afflicts ordinary memories. Subsequent longitudinal studies, however, have complicated this picture considerably: when researchers compared accounts gathered within days of an event to accounts gathered years later, they discovered that details had frequently been altered, omitted, or even fabricated, even though the individuals reporting them expressed unwavering confidence in their accuracy. This persistent mismatch between subjective certainty and objective consistency implies that _______________.

Imagine a distant planet identical to Earth in every visible respect, except that the clear liquid its inhabitants call "water" is not H2O but a different compound, XYZ, that happens to look, taste, and behave exactly the same. (A) Even though the two speakers hold identical thoughts and mental images when they use the word, their statements refer to two different substances, because the underlying chemical composition fixes what a word ultimately picks out. (B) When an Earthling and a Twin Earthling each say the word "water," they seem to mean the same thing, since neither could tell the substances apart without a chemistry lab. (C) Philosopher Hilary Putnam used this scenario to argue that the meaning of a word is not determined solely by what happens inside a speaker's head.

The ecological footprint, a widely cited measure of how much biologically productive land and water a population requires to sustain its consumption, has become one of the most familiar tools for communicating humanity's environmental impact. By converting diverse activities, from driving to eating meat, into a single unit of land area, the measure allows policymakers to grasp whether a lifestyle exceeds what the planet can regenerate. (A) Because the footprint aggregates dissimilar impacts, such as carbon emissions and water scarcity, into one composite figure, it can obscure important differences among problems that require distinct policy responses. A region might reduce its footprint by lowering carbon emissions while simultaneously depleting a local aquifer, yet the aggregate number could still appear to improve, concealing damage that demands urgent attention. (B) This simplicity, however, is also the source of its most persistent criticism. (C) Furthermore, the method assumes that all bio-productive land is roughly interchangeable, treating a hectare of forest as equivalent to a hectare of farmland, even though the two provide markedly different ecological functions.

Scarcity cues of this kind are becoming increasingly common across online retail platforms, appearing on everything from hotel bookings to concert tickets. A shopper browsing an online store notices that a particular item is marked as "only three left in stock." ( ① ) Before seeing this notice, the shopper had regarded the item with only mild interest, uncertain whether it was worth purchasing at all. ( ② ) After seeing the notice, however, the same shopper suddenly feels a pressing urge to complete the purchase before the remaining stock disappears, even though nothing about the item itself has changed. ( ③ ) This shift in urgency illustrates how scarcity cues can transform hesitation into immediate action within moments. ( ④ ) Retailers are well aware of this dynamic, which is why such notices frequently appear even when actual stock levels are difficult for customers to verify independently. ( ⑤ ) Whether the stated scarcity is genuine or exaggerated, its psychological effect on the shopper's behavior remains remarkably similar.

주어진 문장: This effect has been demonstrated so consistently across age groups and subject areas that few findings in cognitive psychology are considered more reliable. Dual coding theory, first proposed to explain why certain kinds of information are remembered more readily than others, holds that the mind processes verbal and visual material through two partially independent channels rather than a single unified system. ( ① ) According to this account, words and other linguistic symbols are encoded primarily through a verbal channel that represents meaning in an abstract, sequential form, while pictures and concrete objects are encoded through an imagery channel that preserves spatial and perceptual detail. ( ② ) When information engages both channels simultaneously, as when a textbook pairs a written explanation with an accompanying diagram, the resulting memory trace benefits from two separate, mutually reinforcing pathways of retrieval rather than just one. ( ③ ) This redundancy explains the well-documented picture superiority effect, whereby concrete, easily visualized words tend to be recalled more accurately than abstract terms that resist mental imagery. ( ④ ) Consequently, dual coding theory has profound implications for instructional design, suggesting that combining carefully chosen visuals with concise verbal explanations can strengthen students' long-term retention of complex material. ( ⑤ )

주어진 문장: As a result, the frequency of an event in someone's memory can feel like solid proof of its real-world frequency, even when the two have little real connection. Imagine two travelers preparing for the same trip: one refuses to fly after watching news coverage of a recent plane crash, while the other books a flight without hesitation. ( ① ) Statistically, air travel remains far safer than driving the same distance by car, yet vivid, emotionally charged images tend to dominate human judgment more powerfully than dry statistics ever could. ( ② ) This tendency, in which people estimate how likely an event is based on how easily examples come to mind rather than on actual data, quietly shapes countless everyday decisions. ( ③ ) News broadcasts that repeatedly feature rare disasters can leave viewers convinced that such events are common, even though official records clearly show the opposite. ( ④ ) Advertisers and politicians alike exploit this pattern, knowing that a single striking anecdote often persuades audiences more effectively than pages of careful statistics ever manage to. ( ⑤ ) Recognizing why memorable examples overshadow objective probability therefore matters, both for making sound personal choices and for noticing when public fear has drifted far from measurable reality.
