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.

Can we affect the rise and fall of the economy?

If you live in a big city, you may have noticed new buildings popping up — a high-rise here, a skyscraper there. The concrete jungles that we've built over the past century have allowed millions of us to live in close proximity, and modern economies to flourish.

This week, we revisit our 2018 conversation about the healing power of nature with psychologist Ming Kuo.

There is a long legacy of leaders exploiting the bodies of vulnerable people in the name of science. This week, the history of eugenics and medical experimentation on enslaved people in the U.S.

At some point in our lives, many of us realize that the way we hear our own voice isn't the way others hear us.

Many of us intuitively feel that the bitter partisanship of American politics is bad for our nation. So should we be concerned about the health of our democracy? This week on Hidden Brain,we revisit two of our favorite conversations about U.S. politics. We start by talking with political scientist John Hibbing about the psychological differences between liberals and conservatives. Then, we explore the role of conflict in democracy with historian David Moss.

We know our actions affect those around us. But how do we know whether our impact is positive? This week on Hidden Brain, what it means to do good in the world.
