Confined to our homes, many of us are experiencing a newfound appreciation for our social relationships. What we may not realize — and what physicians and researchers have only recently started emphasizing — is the importance of these connections to our physical health. This week, we talk with former U.S. Surgeon General Vivek Murthy about why he considers loneliness a matter of public health, and how we can all deepen our social ties.

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.

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.

What's the point of money? The answer might seem obvious: we need it to get paid for our work, and to buy the things we need. But there's also a deeper way to look at the role of money in our lives.

Our memories are easily contaminated. We can be made to believe we rode in a hot air balloon or kissed a magnifying glass — even if those things never happened. So how do we know which of our memories are most accurate? This week, psychologist Ayanna Thomas explains how memory works, how it fails, and ways to make it better.

Do you ever catch yourself yelling at your Alexa? Or typing questions into Google that you would never ask aloud? This week, we explore our changing relationship with technology.

More than 70,000 people died of drug overdoses in 2017 — many of them from heroin and other opioids. One of the most widely-used tools to confront this crisis is a drug called naloxone. It can reverse an opioid overdose within seconds, and has been hailed by first responders and public health researchers. But in 2018, two economists released a study that suggested naloxone might be leading some users to engage in riskier behavior — and causing more deaths than it saves. This week, we talk with researchers, drug users, and families about the mental calculus of opioid use, and why there's still so much we're struggling to understand about addiction. This episode originally aired in October 2018.

As a society, we talk about sex more openly today than ever before. But so much still goes unsaid. This week on the Hidden Brain radio show, complicated stories of intimacy and attraction.

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.
