Studying Great Apes and Cultural Diversity To Understand the Human Mind

Psychologists want to understand how the human mind is extraordinary among animal minds and where the unique aspects of human minds and behaviors come from. To build scientific understanding of human minds, we must study the wide range of humans across cultures, to know what all humans have in common and which aspects of human minds are diverse. However, this is not enough—studying humans across cultures tells us how humans think and act, not how they are unique among animals. To understand how humans are similar and different from other animals, we must study other animals too, especially our close primate relatives, the great apes, who have minds that are similar to ours in many, but not all, ways. So, to understand human minds and behaviors, researchers should study humans and non-humans at a scale that allows us to explore the origins of the similarities and differences of minds and behaviors across our world today.
