It is undeniably true that Malcolm Gladwell is best known for his full-length books. However, over the course of his long career, he has written several dozen articles. Nineteen of those articles are collected in What the Dog Saw (published in 2009).
All of these stories attempt to show readers the world through the perspective of different people (who are described in the section titles), all while incorporating concepts like criminal profiling, mental illness, and the differences between early and late "bloomers" as Gladwell calls them. The book is divided into three categories: 1) "Obsessives, Pioneers, and other varieties of Minor Genius", 2) "Theories, Predictions, and Diagnoses," and 3) "Personality, Character, and Intelligence."
When it debuted, What the Dog Saw became an instant New York Times bestseller and received incredibly positive reviews. The Guardian, for example, loved the book and wrote that "one virtue of What the Dog Saw is that the pieces are perfectly crafted: they achieve their purpose more effectively when they aren't stretched out."
