๐Ÿ“–Reading Passage (C1)

Read the passage carefully before attempting Exercise 1 (Multiple Choice) and Exercise 2 (Fill in the blanks dropdown) below.

Imagine you are offered two jars of jam to taste-test: one containing four flavours, the other twenty-four. Which display would make you more likely to buy? Most people, instinctively, would gravitate towards the larger selection, seduced by the apparent generosity of choice. Yet a now-famous study conducted by psychologists Sheena Iyengar and Mark Lepper at Columbia University found precisely the opposite effect: shoppers presented with fewer options were significantly more likely to make a purchase. This counterintuitive phenomenon, known as the paradox of choice, encapsulates a deeper truth about the human mind — that more information does not necessarily lead to better decisions, and may, in fact, paralyse us entirely.

For much of the twentieth century, economists operated on the assumption that human beings are fundamentally rational agents, calculating costs and benefits with something approaching mathematical precision before arriving at optimal outcomes. This model, elegant in its simplicity, has been progressively dismantled by decades of behavioural research. Pioneered by Daniel Kahneman and Amos Tversky in the 1970s, the field of cognitive psychology introduced the concept of heuristics — mental shortcuts that allow the brain to process complex information quickly. Efficient though these shortcuts often are, they introduce systematic biases that distort our perception of risk, probability, and value. We are, it turns out, not nearly as rational as we would like to believe.

Among the most pervasive of these biases is anchoring, whereby the first piece of information encountered exerts a disproportionate influence over all subsequent judgements. A product initially priced at £500 and then reduced to £350 feels like a bargain, even if £350 was the intended price all along. Equally insidious is the sunk cost fallacy — the tendency to continue investing time, money, or effort in a failing endeavour simply because of what has already been spent. Not only does this bias affect individual consumers and investors, but it has also been shown to influence military commanders, politicians, and institutional leaders who perpetuate disastrous policies rather than acknowledge that their original judgement was flawed.

What complicates the picture further is the role of emotion in decision-making. Neuroscientist Antonio Damasioโ€™s research on patients with damage to the emotional centres of the brain revealed something striking: without the capacity to feel, these individuals were unable to make even the most trivial decisions, despite possessing intact reasoning ability. Far from being the enemy of good judgement, emotion appears to be an essential component of it — providing the motivational pull that rational analysis alone cannot supply. The implication is not that we should surrender entirely to our feelings, but rather that dismissing emotion as mere irrationality misrepresents how the mind actually functions.

Recognising our cognitive vulnerabilities, then, is arguably the first step towards making more considered choices. Strategies such as deliberate reframing, seeking disconfirming evidence, and imposing cooling-off periods before major commitments have all been shown to reduce the influence of bias. Yet there is a certain irony embedded in the very notion of overcoming bias through conscious effort, given that the biases themselves often operate below the threshold of awareness. Rarely has the gap between what we believe about our own rationality and what the evidence actually suggests been so stark — or so humbling.

Perhaps the most unsettling conclusion to emerge from decades of decision-making research is this: the feeling of certainty that accompanies a decision is, in itself, no reliable guide to its quality. Confidence and correctness, it seems, are far less correlated than most of us would care to admit.
