NPR: Hidden Brain

There's a core belief embedded in the story of the United States — the American Dream. Today we look at the state of that dream as we revisit our 2018 conversation with economist Raj Chetty. We'll ask some questions that carry big implications: can you put an economic value on a great kindergarten teacher? How is it that two children living just a few blocks from each other can have radically different chances in life? And what gives Salt Lake City an edge over Cleveland when it comes to offering people better prospects than their parents?

In a fit of anger or in the grip of fear, many of us make decisions that we never would have anticipated. This week, we look at situations that make us strangers to ourselves — and why it's so difficult to remember what these "hot states" feel like once the moment is over.

Envy is one of the most unpleasant of all human emotions. It also turns out to be one of the most difficult for researchers to study. And yet, there's mounting evidence that envy is a powerful motivator. This week, we explore an emotion that can inspire us to become better people — or to commit unspeakable acts.

Many of us believe we know how we'd choose to die. We have a sense of how we'd respond to a diagnosis of an incurable illness. This week, we have the story of one family's decades-long conversation about dying. What they found is that the people we are when death is far in the distance may not be the people we become when death is near.

Anyone who's tried (and failed) to follow a diet knows that food is more than fuel. This week, we revisit our 2018 episode about the psychology behind what we eat, what we spit out, and when we come back for more.
