- Humans have an ability called theory of mind: We are able to think about others' thoughts and emotions
- Research shows that great apes may have a richer appreciation of others' minds than expected
One of the things that defines humans most is our ability to read others' minds -- that is, to make inferences about what others are thinking. To build or maintain relationships, we offer gifts and services -- not arbitrarily, but with the recipient's desires in mind. When we communicate, we do our best to take into account what our partners already know and to provide information we know will be new and comprehensible. And sometimes we deceive others by making them believe something that is not true, or we help them by correcting such false beliefs.
