In a similar study, researchers from the Massachusetts Institute of Technology traveled to a remote location in northwestern Brazil to test members of the Pirahã tribe. The researchers conducted experiments and discovered that the tribespeople don’t have words for numbers. They do have words that mean “some” and “more,” but they don’t have words for precise numbers such as “one” or “three.” Instead, they express quantities in relative terms-that is, in comparison to other numbers or objects. So a tribesperson is not able to say “five trees” or “ten trees” but can say “some trees,” “more trees,” or “many trees.”
