Downey does a solid job of explaining why statistical analysis can fail, but overall, the book is a mixed bag.
A data scientist explains the common pitfalls of statistical analysis.
Sometimes we seem to be drowning in data and statistics that are complex, contradictory, and opaque. Downey, a professor emeritus of computer science at Olin College and author of several books on computer programming, sets out to make understanding it easier. In this book, the author works his way through a number of problems. He sees statistical analysis as an important and useful tool for decision-making, but he admits that things can go terribly wrong, regarding issues ranging from health diagnoses to chess rankings to earthquake predictions. He examines common errors like the base rate fallacy, selection bias, and length-biased sampling, using visualizations rather than equations wherever possible. The chapter on how flawed analysis affected the early attempts to track the spread of the Covid-19 pandemic is particularly illustrative—and worrying. Modeling can generate counterintuitive outcomes, such as Simpson’s paradox, in which aggregates do not (apparently) match the components. A key issue in statistical analysis is finding the right place in a dataset to start, and Downey does not provide much guidance on this element. He assumes that publicly available data is reliable, but this is not always the case, and politicians and advocates from across the spectrum are usually experts at manipulating numbers to support their own conclusions. Guidance from Downey on how to separate valid source data from misleading material, perhaps in a concluding summary chapter, would have been useful. Broadly, we might have expected more practical advice from an author who clearly knows his subject. This is an interesting book, but many sections require a close reading and a basic familiarity with the math, so it is not for everyone.

A virtuoso performance and an ode to an undervalued medium created by two talented artists.
The veteran actor, comedian, and banjo player teams up with the acclaimed illustrator to create a unique book of cartoons that communicates their personalities.
Martin, also a prolific author, has always been intrigued by the cartoons strewn throughout the pages of the New Yorker. So when he was presented with the opportunity to work with Bliss, who has been a staff cartoonist at the magazine since 1997, he seized the moment. “The idea of a one-panel image with or without a caption mystified me,” he writes. “I felt like, yeah, sometimes I’m funny, but there are these other weird freaks who are actually funny.” Once the duo agreed to work together, they established their creative process, which consisted of working forward and backward: “Forwards was me conceiving of several cartoon images and captions, and Harry would select his favorites; backwards was Harry sending me sketched or fully drawn cartoons for dialogue or banners.” Sometimes, he writes, “the perfect joke occurs two seconds before deadline.” There are several cartoons depicting this method, including a humorous multipanel piece highlighting their first meeting called “They Meet,” in which Martin thinks to himself, “He’ll never be able to translate my delicate and finely honed droll notions.” In the next panel, Bliss thinks, “I’m sure he won’t understand that the comic art form is way more subtle than his blunt-force humor.” The team collaborated for a year and created 150 cartoons featuring an array of topics, “from dogs and cats to outer space and art museums.” A witty creation of a bovine family sitting down to a gourmet meal and one of Dumbo getting his comeuppance highlight the duo’s comedic talent. What also makes this project successful is the team’s keen understanding of human behavior as viewed through their unconventional comedic minds.

PERSPECTIVES
An ebullient nature lover’s paean to birds.
A charming bird journey with the bestselling author.
In his introduction to Tan’s “nature journal,” David Allen Sibley, the acclaimed ornithologist, nails the spirit of this book: a “collection of delightfully quirky, thoughtful, and personal observations of birds in sketches and words.” For years, Tan has looked out on her California backyard “paradise”—oaks, periwinkle vines, birch, Japanese maple, fuchsia shrubs—observing more than 60 species of birds, and she fashions her findings into delightful and approachable journal excerpts, accompanied by her gorgeous color sketches. As the entries—“a record of my life”—move along, the author becomes more adept at identifying and capturing them with words and pencils. Her first entry is September 16, 2017: Shortly after putting up hummingbird feeders, one of the tiny, delicate creatures landed on her hand and fed. “We have a relationship,” she writes. “I am in love.” By August 2018, her backyard “has become a menagerie of fledglings…all learning to fly.” Day by day, she has continued to learn more about the birds, their activities, and how she should relate to them; she also admits mistakes when they occur. In December 2018, she was excited to observe a Townsend’s Warbler—“Omigod! It’s looking at me. Displeased expression.” Battling pesky squirrels, Tan deployed Hot Pepper Suet to keep them away, and she deterred crows by hanging a fake one upside down. The author also declared war on outdoor cats when she learned they kill more than 1 billion birds per year. In May 2019, she notes that she spends $250 per month on beetle larvae. In June 2019, she confesses “spending more hours a day staring at birds than writing. How can I not?” Her last entry, on December 15, 2022, celebrates when an eating bird pauses, “looks and acknowledges I am there.”
