Henrich defends this sweeping thesis with several studies, including a test known as the Triad Task. Subjects are shown three images—say, a rabbit, a carrot, and a cat. The goal is to match a “target object”—the rabbit—with a second object. A person who matches the rabbit with the cat classifies: The rabbit and the cat are animals. A person who matches the rabbit with the carrot looks for relationships between the objects: The rabbit eats the carrot.
