Americans are so accustomed to the standard intersection that we rarely consider how dangerous it can be — as well as costly, time-wasting, and polluting. Is it time to embrace the lowly, lovely roundabout?

Bjorn Andersen killed 111 minke whales this season. He tells us how he does it, why he does it, and what he thinks would happen if whale-hunting ever stopped.  (This bonus episode is a follow-up to our series “Everything You Never Knew About Whaling.")

In three stories from our newest podcast, host Zachary Crockett digs into sports mascots, cashmere sweaters, and dinosaur skeletons. 

In the final episode of our whale series, we learn about fecal plumes, shipping noise, and why "Moby-Dick" is still worth reading. (Part 3 of "Everything You Never Knew About Whaling.")

For years, whale oil was used as lighting fuel, industrial lubricant, and the main ingredient in (yum!) margarine. Whale meat was also on a few menus. But today, demand for whale products is at a historic low. And yet some countries still have a whaling industry. We find out why. (Part 2 of “Everything You Never Knew About Whaling.”)

Whaling was, in the words of one scholar, “early capitalism unleashed on the high seas.” How did the U.S. come to dominate the whale market? Why did whale hunting die out here — and continue to grow elsewhere? And is that whale vomit in your perfume? (Part 1 of “Everything You Never Knew About Whaling.”)

Actually, the reasons are pretty clear. The harder question is: Will we ever care enough to stop?

Sure, you were “in love.” But economists — using evidence from Bridgerton to Tinder — point to what’s called “assortative mating.” And it has some unpleasant consequences for society.

But as C.E.O. of the resurgent Microsoft, he is firmly at the center of the A.I. revolution. We speak with him about the perils and blessings of A.I., Google vs. Bing, the Microsoft succession plan — and why his favorite use of ChatGPT is translating poetry.

Probably not. The economist Kelly Shue argues that E.S.G. investing just gives more money to firms that are already green while depriving polluting firms of the financing they need to get greener. But she has a solution.

Gun control, abortion rights, drug legalization — it seems like every argument these days claims that if X happens, then Y will follow, and we’ll all be doomed to Z. Is the slippery-slope argument a valid logical construction or just a game of feelingsball?

He turned a small Hollywood talent agency into a massive sports-and-entertainment empire. In a freewheeling conversation, he explains how he did it and why it nearly killed him.

Sure, markets work well in general. But for some transactions — like school admissions and organ transplants — money alone can’t solve the problem. That’s when you need a market-design wizard like Al Roth. Plus: We hear from a listener who, inspired by this episode, made a remarkable decision.

Museums are purging their collections of looted treasures. Can they also get something in return? And what does it mean to be a museum in the 21st century? (Part 3 of “Stealing Art Is Easy. Giving It Back Is Hard.”)

The world’s great museums are full of art and artifacts that were plundered during an era when plunder was the norm. Now there’s a push to return these works to their rightful owners. Sounds simple, right? It's not. (Part 2 of “Stealing Art Is Easy. Giving It Back Is Hard.”)

How did a freshly looted Egyptian antiquity end up in the Metropolitan Museum of Art? Why did it take Kim Kardashian to crack the case? And how much of what you see in any museum is stolen? (Part 1 of “Stealing Art Is Easy. Giving It Back Is Hard.”)

Whether it’s a giant infrastructure plan or a humble kitchen renovation, it’ll inevitably take way too long and cost way too much. That’s because you suffer from “the planning fallacy.” (You also have an “optimism bias” and a bad case of overconfidence.) But don’t worry: we’ve got the solution. 

Every language has its taboo words (which many people use all the time). But the list of forbidden words is always changing — and those changes tell us some surprising things about ourselves. Note: The swear words in this episode have been bleeped out. To hear a version of this episode without the bleeps, go to freakonomics.com.

Delaware is beloved by corporations, bankruptcy lawyers, tax avoiders, and money launderers. Critics say the Delaware “franchise” is undemocratic and corrupt. Insiders say it’s wildly efficient. We say: they’re both right.

Many companies say they want to create more opportunities for Black Americans. One company is doing something concrete about it. We visit the South Side of Chicago to see how it’s working out.
