As we go through life, we’re constantly trying to figure out what other people are thinking and feeling. Psychologist Liane Young says this ability to assess other people’s thoughts is an extraordinary feat of cognition. This week, in a favorite episode from our archives, we explore this mental superpower — and how it can lead us astray.

In our conversation with Liane Young, we explore:

*The uniquely human ability to think about the minds of other people, which scientists refer to as "theory of mind."

*How and when young children develop this ability to intuit what's happening in other people's minds.

*Why our understanding of other people's minds affects our moral judgments — and how those judgments can be disabled.

*How misreading another person's intentions can affect our lives in both small and significant ways.

Then, in the second part of this week's show, we welcome back researcher Fred Luskin, who responds to listeners' questions about grudges. If you missed the original conversation with Fred Luskin, listen to our episode No Hard Feelings.
