In most examples, the reason for choosing the “wrong” data is simple: it’s readily available, while the more relevant data is harder to find. One way to limit the risk of dangerous shortcuts is to label the data with precision. “Consumption” and “production” of sugar are different. But sometimes even an accurate label can be grossly misleading, as the example of “Homicides recorded by police in 2016” demonstrates.

There is no substitute for two basic disciplines of rigorous analysis. The first is to read the fine print patiently. In the Office of National Statistics report on crime in England and Wales for 2016, you’d have had to read down to page 25 of a 58-page report to find an explanation about the Hillsborough deaths. The other is simply to ask. Back in the day when gathering numbers meant—mostly—interviewing people with access to them, it was natural enough to ask them questions that put numbers in context. Now that the world’s information is available at our fingertips, it has become all too easy to skip that step.
