Don't hate the replicator, hate the game

The world of science has been stuck in an existential crisis over whether we actually know the things we thought we knew. Re-running an old study today doesn't always yield the same result. Same with re-enacting old experiments. Collectively, this is known as the “replication crisis.” Economist Abel Brodeur has come up with one way to help fix this crisis: he’s invented an internationally crowdsourced surveillance system, designed to keep social scientists honest. He calls it the “Replication Games.” Further Listening:Fabricated data in research about honesty. You can't make this stuff up. Or, can you? The Experiment Experiment How Much Should We Trust Economics?This episode was hosted by Mary Childs and Alexi Horowitz-Ghazi.

Book tour and ticket info here.Greenland has said it is not for sale. Denmark has said it can’t even legally sell Greenland. And at a security conference in Munich over the weekend, U.S. lawmakers spent a lot of time trying to walk back some of President Trump’s recent threats to try to buy, or even take over, the territory. But whether Trump can or will or should try to control or purchase a territory that doesn’t want to be sold is not the interesting question. What is interesting is how we got to this moment. And, how we might gracefully get out of it. Greenland is valuable for its minerals and because of its physical location in the world. (It’s easy to keep an eye on other countries from Greenland).Our latest: How the U.S. dropped the ball on the rare earths race. And one way the U.S. gets strategic locations without threatening to buy or take over an entire territory.Further listening: - Is Greenland really an untapped land of riches?- Add to cart: GreenlandPre-order the Planet Money book and get a free gift. / Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.This episode was produced by Willa Rubin with help from Sam Yellowhorse Kesler.

Book tour tickets and details here.Today, the story of three inventions. The first, the sewing machine, was created by a selfish and ambitious inventor who wanted all the credit and was willing to fight a war for it. The second, a more modern invention, was made by an Italian inventor who wanted only to connect the world through video, so “evvvvverybody can talk with evvvvverybody else.”And, a third invention that tied them both together across more than a century. The patent pool.How do people get motivated to invent, and how do they get rewarded for their ideas? Usually through a patent. And, when the thicket of patents becomes too thick, how do we simplify, and make it so inventors can work together? The answer will involve bitter rivals, a sewing machine war, the nine no-no’s of anti-trust, and something called a gob-feeder. Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.This episode was hosted by Erika Beras and Sam Yellowhorse Kesler.

Book tour tickets and details here.The recent protests in Iran are about so many things. Human rights, corruption, freedom. But this time – they are also motivated by economic hardship. Hardship caused, in part, by US sanctions. The US has been sanctioning Iran in one way or another for 47 years. But sanctions, as a tool, only work some of the time, and US sanctions on Iran have not always conformed to what experts consider best practices.On today’s episode: What did US sanctions do to Iran's economy? How did they feed into the latest protests and crackdown in Iran? Sanctions are supposed to avert war, but how different from war are they?To learn more about the protests in Iran and the country’s history, check out our great friends at Throughline:Iran Protests ExplainedIran and the U.S., Part One: Four Days In AugustIran and the U.S., Part Two: Rules of EngagementIran and the U.S., Part Three: Soleimani’s IranSubscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.This episode was hosted by Mary Childs and Nick Fountain.

Planet Money book tour ticket info and dates here. A record number of Americans with poor or just okay credit are behind on their car payments. And once last year’s numbers are tallied, an estimated 3 million cars will have been repossessed in 2025. That would be on par with how bad it got during the Great Recession. What’s going on? And why now? Today on the show, we focus on the micro part of the story to answer the macro question. First, we hear a favorite story of ours from 2019. We follow the lifecycle of a delinquent car loan from three different perspectives: the salesman, the driver, and the repo man. Then we’ll hear an update from them in 2026 as we try to find out why so many Americans are behind on their car payments. Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.This episode is hosted by Kenny Malone and Preeti Varathan.

In the 1990s, Congress created HOPE VI, a program that demolished old public housing projects and replaced them with more up-to-date ones. But the program went further than just improving public housing buildings. HOPE VI was designed to transform neighborhoods with concentrated poverty into neighborhoods that attracted people with different incomes. Some people who moved to HOPE VI neighborhoods earned too much to qualify for public housing. And some even paid for market-rate housing. The idea was that this would help create new opportunities for the low-income people who lived there and even lift people out of poverty.For years though, there wasn’t a clear answer to whether this approach actually succeeded. A new working paper from Raj Chetty and the team at Opportunity Insights finally provides some answers. On today’s show: Who really benefits when people living in poverty are more connected to their surrounding communities? Are there lessons from the HOPE VI experiment that could apply to other kinds of policies aimed at fostering upward mobility?More about Opportunity Insights’ study and a link to their interactive map here.Pre-order the Planet Money book and get a free gift. / Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.To manage podcast ad preferences, review the links below:See pcm.adswizz.com for information about our collection and use of personal data for sponsorship and to manage your podcast sponsorship preferences.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
