What's The Antidote To Political Apathy?　TED Radio Hour GUY RAZ, HOST: So here in Washington, D.C., where we produce this show, the population is roughly 650,000 people. And of those people, about 450,000 are eligible to vote. But of those, in the last mayor's race, just 36,000 people elected the new mayor. That's 5 percent of the city's entire population. Call it apathy, or sloth, which is our next sin. DAVE MESLIN: You're not using your body. Maybe you're not using your mind. It's a physical laziness but also maybe a spiritual laziness. RAZ: This is Dave Meslin. He's a community organizer in Toronto. And in his job, he runs into political apathy all the time. People don't vote. They don't follow the issues. They don't even know who represents them in government. They're sloths. But actually, according to Dave, they're not. I mean, you don't think that, like, that people tune out of politics or whatever's going on in ...

And then if you ask, is this going to pose you a personal risk or really harm you or your family? - then most people say no. RAZ: This is Per Espen Stoknes. STOKNES: I teach at the Norwegian Business School in green economics. And I'm also a climate psychologist, researching in how people respond to the climate science and climate news. RAZ: Per Espen has been trying to figure out why it's so hard to communicate the urgency of climate change to most pe...
