In their classic How to Analyze People on Sight, published in 1921, the Benedicts divide humanity into five types, all of which are full of the most deliciously blatant stereotypes known to man. Fat people enjoy life! "Cerebral" types have large heads! Muscular people like to work, but don't like to think too hard. Also, they have square jaws. People with a large lung capacity should marry other people with large lungs. The beginning of the work makes it clear the course in which it will run. "The most essential thing in the world to any individual is to understand himself. The next is to understand the other fellow. For life is largely a problem of running your own car as it was built to be run, plus getting along with the other drivers on the highway. From this book you are going to learn which type of car you are and the main reasons why you have not been getting the maximum of service out of yourself."
