In the wake of the controversy that greeted his paper, Everett encouraged scholars to come to the Amazon and observe the Pirahã for themselves. The first person to take him up on the offer was a forty-three-year-old American evolutionary biologist named Tecumseh Fitch, who in 2002 co-authored an important paper with Chomsky and Marc Hauser, an evolutionary psychologist and biologist at Harvard, on recursion. Fitch and his cousin Bill, a sommelier based in Paris, were due to arrive by floatplane in the Pirahã village a couple of hours after Everett and I did. As the plane landed on the water, the Pirahã, who had gathered at the river, began to cheer. The two men stepped from the cockpit, Fitch toting a laptop computer into which he had programmed a week’s worth of linguistic experiments that he intended to perform on the Pirahã. They were quickly surrounded by curious tribe members. The Fitch cousins, having travelled widely together to remote parts of the world, believed that they knew

Cargo cult activity in the Pacific region increased significantly during and immediately after World War II, when large amounts of manpower and materials were brought in by the Japanese and American combatants, and this was observed by the residents of these regions. When the war ended, the military bases were
