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.

Envy is one of the most unpleasant of all human emotions. This week, we explore an emotion that can inspire us to become better people — or to commit unspeakable acts.

More than 70,000 people died of drug overdoses last year — 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 earlier this year, 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.

We all know the downsides of being poor. But what about the downsides of being rich? This week, we explore the psychology of scarcity...and excess.

It doesn't just keep them entertained. New research highlights an unexpected positive impact — and also shows that when a parent sings to a child, the parent can benefit, too.

Marriage is hard — and there are signs it's become even harder in recent decades. We examine how long-term relationships have changed, and whether we might improve marriage by asking less of it.

The desire to find our tribe is universal. We like to know who we are and where we belong. This week, how this fascination has led to a thriving industry built on the sale of personality tests.
