Bonobos Show They Understand Ignorance: A Breakthrough in Theory of Mind Research
2025-02-04
A new study demonstrates that bonobos possess theory of mind, understanding others' lack of knowledge and acting accordingly. Researchers designed an experiment where bonobos helped an experimenter find hidden treats. Results showed bonobos pointed faster and more often when they realized the experimenter didn't know the treat's location. This indicates bonobos track and respond to differing perspectives, suggesting theory of mind might be more evolutionarily ancient than previously thought, and potentially present in our common ancestor.
