How Charts Lie: Getting Smarter about Visual Information

by Alberto Cairo Narrated by Jonathan Yen

Overview

We've all heard that a picture is worth a thousand words, but what if we don't understand what we're looking at? Social media has made charts, infographics, and diagrams ubiquitous-and easier to share than ever. We associate charts with science and reason; the flashy visuals are both appealing and persuasive. Pie charts, maps, bar and line graphs, and scatter plots (to name a few) can better inform us, revealing patterns and trends hidden behind the numbers we encounter in our lives. In short, good charts make us smarter-if we know how to read them.



However, they can also lead us astray. Charts lie in a variety of ways-displaying incomplete or inaccurate data, suggesting misleading patterns, and concealing uncertainty-or are frequently misunderstood, such as the confusing cone of uncertainty maps shown on TV every hurricane season. To make matters worse, many of us are ill-equipped to interpret the visuals that politicians, journalists, advertisers, and even our employers present each day, enabling bad actors to easily manipulate them to promote their own agendas.



In How Charts Lie, data visualization expert Alberto Cairo teaches us to not only spot the lies in deceptive visuals, but also to take advantage of good ones to understand complex stories.

As this entertaining addition demonstrates, the "how to lie with statistics" genre is alive and well.

Cairo (Chair, Visual Journalism/Univ. of Miami; The Truthful Art: Data, Charts, and Maps for Communication, 2016, etc.) points out that "charts may lie…because they display either the wrong information or too little information. However, a chart can show the right type of information and lie anyway due to poor design or labeling." In a cheerful introductory chapter, the author explains that, while writing was invented about 5,000 years ago and charts weren't used until the late 1700s, both are encoded forms of communication with a structure and vocabulary. Readers receive well-researched information about the makeup of a chart along with the warning that this knowledge, like rules of grammar, is necessary but not sufficient. It's essential to pay attention. Cairo begins with a U.S. map, almost entirely red, that many claim shows the overwhelming popularity of Donald Trump in 2016. But how could that be if he received only 46 percent of the vote? The trick is that the map label shows not voters but counties with Trump majorities. Since large counties (rural) mostly voted for him and small counties (urban) didn't, such a map is overwhelmingly red. The map, although real, is used to lie. In the generously illustrated chapters that follow, the author delivers a painless, if often uncomfortable education. On a trivial level, one must know what a chart is measuring. A chart of homeless schoolchildren in Florida reveals counties with more than 20 percent. The streets are not full of sleeping students because "homeless" is not defined as "no home" but rather as "lacking a fixed, regular nighttime residence." There are plenty of no-brainers, sadly widely ignored, such as, "correlation is not causation." The graph showing that cigarette smoking increases in nations with a greater life expectancy does not prove that smoking is healthy.

An ingenious tool for detecting flaws in charts, which nowadays seem mostly deliberate.
