Modern consumers are routinely assured that an abundance of options is an unambiguous good, a self-evident marker of freedom and prosperity. Supermarkets stock dozens of varieties of a single humble condiment, and streaming platforms dangle thousands of titles before their subscribers at the touch of a button. Conventional economic thinking holds that each additional alternative can only enhance welfare, since a rational agent may simply ignore whatever does not suit him and select from the remainder. This assumption quietly underpins much of modern retailing and the sprawling emporia in which it takes place. Yet a growing body of psychological research suggests that the relationship between choice and satisfaction is far more equivocal than this tidy logic implies. The intuition that generous variety is an unmixed blessing, so natural that it scarcely seems worth defending, rests on shakier foundations than one might suppose. Beyond a certain threshold, ( 1 ), leaving people less inclined to purchase, less confident in the decisions they do make, and more susceptible to lingering regret afterward. The very profusion that markets celebrate can quietly corrode the pleasure of choosing. In this domain, at least, generosity has a curiously paradoxical limit.
The mechanism behind this reversal is instructive and surprisingly intuitive once stated. When the field of candidates is small, a shopper can weigh the trade-offs with relative ease and arrive at a defensible verdict without undue strain. As the array expands, however, the cognitive burden of comparison mounts steadily, and the opportunity cost of any single selection becomes painfully conspicuous. Every attractive feature forgone in the chosen item is embodied by some rejected alternative, and the mind dwells uneasily on these phantom losses long after the transaction is complete. In a celebrated experiment, shoppers offered a limited display of jams proved markedly more likely to buy than those confronted with an extensive one. The larger assortment drew curious onlookers in impressive numbers but ( 2 ), a paralysis born not of indifference but of an overtaxed capacity to discriminate. The abundance that attracted them was precisely what prevented them from committing.
None of this implies that variety should be abolished, for a world of enforced uniformity would be its own kind of tyranny, and few would trade genuine options for a single mandated product. The insight is rather that choice carries hidden costs which designers of markets, policies, and institutions ignore at their peril. Thoughtful curation, sensible default settings, and the grouping of options into manageable categories can preserve genuine autonomy while sparing people the corrosive burden of unlimited deliberation. A well-designed menu guides without dictating, offering enough to satisfy varied tastes but not so much as to overwhelm. What consumers ultimately crave is not the maximum conceivable number of alternatives but the quiet confidence that they have chosen well. Recognising that more is not invariably better ( 3 ), a discipline that benefits harried individuals and the institutions that serve them alike.
(1) 正解 2. additional choices can become a burden
第1段落は選択肢が一定量を超えると満足を損なうという逆説を述べる。空所直後に「購入意欲が下がり、後悔しやすくなる」とあるので、追加の選択が負担になるという2が正解。
(2) 正解 2. seldom translated into sales
第2段落のジャム実験で、少数陳列の方が購入率が高かったと対比されている。大きな品揃えは見物客を集めたが購入には結びつかなかったとする2が正解。
(3) 正解 1. amounts to a form of restraint
第3段落は多いことが常に良いとは限らないと認めることが節度・自制につながると結ぶ。1が正解。
