The chosen study is a 1998-1999 survey of approximately 25 orangutans (Pongo pygmaeus) in the Meratus forest in Borneo. The Meratus forest has had no naturally occurring orangutan population since 1997, and it is a popular location to "reintroduce rehabilitant orangutans and translocate wild individuals (Grundmann, 300)."

The researchers found that the orangutans could be grouped into three separate classes; the experts, the students, and naïve ones.
