How Charts Lie

Note This is placeholder / sample text

Cairo’s argument is essentially that charts lie in a small number of predictable ways: they obscure uncertainty, they use the wrong form for the data, they cherry-pick the range or comparison, or they exploit our perceptual biases. The book walks through each category with real examples drawn mostly from journalism and politics, which makes it concrete in a way that a more abstract treatment wouldn’t be.

What I found most useful is the chapter on uncertainty. We are very bad, culturally, at visualizing ranges and confidence intervals — both because designers omit them and because audiences misread them when they’re included. Cairo is honest that there is no clean solution: showing uncertainty more accurately often makes charts harder to read and less persuasive, which creates pressure toward false precision. That tension doesn’t get resolved, which I appreciated.

The book is aimed at a general audience and reads accordingly — accessible, occasionally a bit repetitive. If you already have a background in statistics or visualization, you will move through it quickly. But the examples are good enough that it’s worth the time regardless of where you’re starting from.
