Imagine walking through a forest at dusk. Out of the corner of your eye, you spot stripes moving through the undergrowth. Your heart races. A tiger. You freeze, adrenaline surging, preparing to run or fight. But when you look again, carefully, you realize it was only the play of light and shadow through tall grass. The tiger that seemed so real was never there at all. This is the central metaphor of Michael Blastland and Andrew Dilnot's remarkable book. The modern world is full of statistical tigers: numbers that seem terrifying, certain, and urgent, but that dissolve into nothing when examined closely. A headline screams that a certain food increases cancer risk by fifty percent. A politician announces that crime has fallen dramatically. A news report claims that your neighborhood is a cancer cluster. Each of these claims carries the weight of numbers, and numbers feel solid, objective, and true. But numbers are not reality. Numbers are representations of reality, created by human beings who make choices about what to count, how to count it, and what to leave out. Every statistic you encounter is the product of countless decisions, assumptions, and compromises. The unemployment rate depends on how you define "unemployed." The cancer risk depends on what baseline you compare against. The crime statistics depend on what crimes get reported and how they get recorded. The problem is that most of us were taught to treat numbers as neutral facts. We learned arithmetic in school, where numbers behaved predictably and followed clear rules. Two plus two always equaled four. A percentage was a percentage. An average was an average. But the numbers we encounter in real life are not like the numbers in textbooks. They are messy, contested, and often deliberately manipulated. Blastland and Dilnot created the BBC Radio 4 program "More or Less" to help ordinary people understand statistics in public life. Through years of investigating statistical claims, they discovered that most misleading numbers are not the result of deliberate lies. Instead, they arise from something more subtle: the gap between what we think numbers mean and what they actually measure. A statistic can be technically accurate and still deeply misleading if we don't understand its context. Consider a simple example. A newspaper reports that eating bacon increases your risk of bowel cancer by…
