We're all pretty good at picking out nonsense in the fancy language of old-school bullshit. But bullshit is much more easily cloaked in the complex, seemingly authoritative language of math, science, and statistics. Calling Bullshit shows us that you don't need a lot of technical expertise to call out problems with data. You just need the ability to think clearly and a bit of practice spotting the common tricks used in the way that numbers are presented. By exuberantly unpacking examples of selection bias and muddled data visualization, clearly distinguishing between correlation and causation, and examining the susceptibility of science to modern bullshit, Bergstrom and West give us a set of powerful intellectual tools to identify and refute this quantitative nonsense. Calling bullshit has always been crucial in a healthy society. Now that it has evolved, it's time to relearn the art of skepticism. Book jacket.
