Hidden Brain

Why is it so hard to guess where we're meant to be? To predict where we'll end up? Nearly all of us have had the experience of traveling down one road, only to realize it's not the road for us. At the University of Virginia, Saras Sarasvathy uses the lens of entrepreneurship to study how we plan and prepare for the future. We kick off our new "Innovation 2.0" series by talking with Saras about how we pursue goals and make decisions.

If you're a parent or a teacher, you've probably wondered how to balance play and safety for the kids in your care. You don't want to put children in danger, but you also don't want to rob them of the joy of exploration. This week, we talk with psychologist Peter Gray about how this balance has changed — for parents and children alike — and what we can do about it.

We've all had those days when all we want is a little treat. Maybe it's a bag of chips, an ice cream sundae or a glass of wine. But sometimes, these desires become all-consuming. This week on the show, psychiatrist Judson Brewer helps us understand the science of cravings, and how we should respond to them.

Anthropologist Tom Pearson was devastated after his daughter Michaela was diagnosed with Down syndrome. When he began to examine that emotional response, he found himself wrestling with questions that have roiled his field for decades. Early anthropologists would often compare people of different backgrounds and abilities, asking questions like: How is one group different from another? Which one is stronger or smarter? And how do we understand people who don’t fit our expectations? This week, we talk with Pearson about his family’s story, and the evolution of our thinking on disability and difference.

If you've ever taken an economics class, you were probably taught that people are rational. But about 50 years ago, the psychologists Daniel Kahneman and Amos Tversky began to chip away at this basic assumption. In doing so, they transformed our understanding of human behavior. This week, we remember Kahneman, who recently died at the age of 90, by revisiting our 2018 and 2021 conversations with him.
