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 Damasioโs 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.

Exercise 1
Read the passage about the psychology of decision-making carefully, then choose the correct answer for each question based on the information given in the text.
Example: According to the text, what term describes the tendency to rely too heavily on the first piece of information encountered?
Answer: Anchoring bias

The Psychology of Decision-Making
Think about the last significant decision you made — perhaps changing jobs, ending a relationship, or choosing where to live. Did you weigh up every option carefully, or did something less rational guide you? Before reading, consider these two questions: Why do intelligent people sometimes make poor decisions despite having access to all the relevant information? And to what extent do our emotions, rather than our reasoning, drive the choices we make? Keep these questions in mind as you read the article below.

Reading Strategies & Comprehension Tips
Skimming for Main Ideas
- Read the first and last sentences of each paragraph quickly to identify the central argument of each section before reading in full. Notice how the passage moves from a concrete example (jam jars) to a broader philosophical conclusion.
- The opening anecdote is not simply an interesting story — it functions as evidence for the passage's central thesis. Ask yourself: what does the jam jar experiment prove?
Scanning for Specific Details
- When scanning for names, dates, or research findings, look for proper nouns and numbers. Notice that the passage mentions specific researchers (Kahneman, Tversky, Damasio, Iyengar, Lepper) — questions may ask you to match a researcher to a specific finding.
- Pay close attention to hedging language such as "arguably," "appears to be," and "has been shown to." These signal the writer's level of certainty and are frequently targeted in comprehension questions about the writer's attitude.
Inferring Meaning and Attitude
- The writer's tone is analytical yet subtly ironic. Phrases like "elegant in its simplicity" (paragraph two) appear complimentary on the surface but carry implicit criticism. Consider what is implied, not just stated.
- Look carefully at the final two paragraphs. The writer does not conclude with straightforward optimism — the tone becomes more unsettling. Ask yourself: is the writer ultimately hopeful or sceptical about our ability to improve decision-making?
Common Reading Pitfalls & Traps
Trap 1: Confusing the Example with the Main Argument
The jam jar study is an illustration, not the passage's central claim. A common mistake is to treat the opening paragraph as the main point and miss the broader argument: that human decision-making is systematically, not occasionally, irrational. Questions asking about the writer's main purpose require you to look beyond the opening example.
Trap 2: Misreading the Role of Emotion
The passage does not argue that emotion improves decision-making or that we should trust our feelings. Nor does it suggest emotion is simply harmful. Damasio's findings are cited to show that emotion is necessary — not sufficient — for good decisions. Avoid oversimplifying this nuanced position in multiple-choice contexts.
Trap 3: Overgeneralising the Writer's Conclusion
The final paragraph states that confidence and correctness are "far less correlated than most of us would care to admit" — not that they are entirely unrelated. Watch out for extreme answer options that overstate the writer's position, such as "the writer believes confidence always leads to poor decisions."
Trap 4: False Synonym Confusion
The word insidious (paragraph three) may be confused with serious or harmful, but its specific meaning relates to something that develops gradually and is difficult to detect. This distinction matters when answering vocabulary-in-context questions.
