Harmon calls his circles embryos—they contain all the elements needed for a satisfying story—and he uses them to map out nearly every turn on, from throwaway gags to entire seasons. If a plot doesn’t follow these steps, the embryo is invalid, and he starts over. To this day, Harmon still studies each film and TV show he watches, searching for his algorithm underneath, checking to see if the theory is airtight. “I can’t not see that circle,” he says. “It’s tattooed on my brain.”
