    The Choices Before Us: Can Fewer Options Lead To Better Decisions?

    An abundance of choices is a good thing, right? In the United States, where choice is often equated with freedom and control, the answer tends to be a resounding 'yes.' But researchers say the relationship between choice and happiness isn't always so clear-cut. This week, we talk with psychologist Sheena Iyengar about making better decisions, and how she's thinking about the relationship between choices and control during the coronavirus pandemic.

    Playing Tight And Loose: How Rules Shape Our Lives

    We all know people who prefer to follow the rules, and others who prefer to flout them. Psychologist Michele Gelfand defines these two ways of being as "tight" and "loose." She says the tight/loose framework can help us to better understand individuals, businesses, and even nations. This week, we look at the core traits of tight and loose worldviews, and how they may shape our lives — from interactions with our spouses to global efforts to fight the coronavirus.

    The Bomb That Didn't Explode: Why Our Fears About Population Growth Didn't Come True

This week on Hidden Brain, we explore how our planet's population is changing, and what that means for us in the century to come.

    Passion Isn't Enough: The Rise Of 'Political Hobbyism' in the United States

    Many Americans feel an obligation to keep up with political news. But maybe we should be focusing our energies elsewhere. Political scientist Eitan Hersh says there's been a rise in "political hobbyism" in the United States. We treat politics like entertainment, following the latest updates like we follow our favorite sports teams. Instead, he says, we should think of politics as a way to acquire power and persuade our neighbors to back the issues we support.

    Secret Friends: Tapping Into The Power Of Imagination

    Where is the line between what is real and what is imaginary? It seems like an easy question to answer: if you can see it, hear it, or touch it, then it's real, right? But what if this way of thinking is limiting one of the greatest gifts of the mind? This week, we meet people who experience the invisible as real, and learn how they hone their imaginations to see the world with new eyes.
