CORRECTION: In this episode, we say that there were only two names left on the 2021 list of Atlantic hurricane names until we resume use of the Greek alphabet letters. In March 2021, the World Meteorological Association decided to end the use of the Greek alphabet, and provided a list of supplementary names instead.   This episode is a re-broadcast. It originally aired in November 2020.  Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But in 2020, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season. We’ve only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names. Guests: Christina M.

When Isabel Briggs Myers imagined that her homegrown personality test would change the world, she couldn’t have pictured this. Today, millions take the Myers-Briggs Type Indicator each year. Countless organizations use it, from General Motors to the CIA. But there’s one field that mostly rolls its eyes at the test: psychology.  In our final chapter, Isabel rescues her indicator from the verge of extinction, but has to make some compromises. And we explore what the Myers Briggs does (and doesn’t) measure, and why people love it despite psychologists' complaints. Listen to Chapter 1 and Chapter 2 of this series. Guests:  Merve Emre is a writer and English professor at the University of Oxford.

At first, it seemed like Isabel Briggs Myers would have nothing to do with personality typology. That was her mother Katharine’s passion project, not hers. But when Isabel enters a tumultuous marriage, she discovers that her mother’s gospel of type might just be the thing to save it.  In Chapter 2, Isabel picks up her mother’s work, and decides to transform it into a marketable product—but first, she has to convince a group of skeptical PhDs that it actually works. Along the way, one particularly dogged researcher notices some issues with her indicator, threatening to undo everything she’d worked for. If you’re new to the series, listen to Chapter 1.

If you’re one of the 2 million people who take the Myers-Briggs Type Indicator every year, perhaps you thought Myers and Briggs are the two psychologists who designed the test. In reality, a mother-daughter team created the test essentially at their kitchen table. In this episode, we look at the unlikely origins of the Myers-Briggs, going all the way back to the late 1800s when Katharine Cook Briggs turned her living room into a “cosmic laboratory of baby training” and set out to raise the perfect child. In this three-part series, we uncover the strange history of the most popular personality test in the world, and how two women revolutionized personality testing—for better or for worse.  Guest:  Merve Emre is a writer and English professor at the University of Oxford.

Honeymoon: It just seems like a word that would have a lovely story behind it, doesn’t it?  When a listener named Eric emailed us from Centerville, Ohio asking about the word, that’s what we were hoping to find. Instead, we found a more bittersweet origin stretching all the way back to an early modern poem. Plus: We take a look at what’s going on in our brains during the honeymoon period—and whether it’s all downhill from there.  If you want us to cover a word on the show, get in touch!

In 1910, a fruit fly geneticist named Thomas Hunt Morgan noticed something strange in one of his specimens. Out of his many, many fruit flies—all with brilliant red eyes—a single fly had white eyes. This fruit fly turned out to be a very big deal. From those white eyes, Morgan eventually figured out that genes can be sex-linked, confirmed that genes exist on chromosomes, and won the Nobel prize. But he also cemented his legacy another way, with what he chose to name that gene: "white". It might sound uninspired, but it kicked off a tradition that decades later gave us names like spatzle, hamlet, and ken and barbie. Here and there, a name went too far, but overall, fanciful names brought joy to researchers and worked well until genes like these were discovered in humans, and everything went awry. Johanna and Senior Producer Elah Feder team up with Helen Zaltzman of The Allusionist to talk about fruit flies, genes, and whether it’s ok to name a gene after a German noodle. Plus, after much demand, we bring you... the origin of "defenestration"! Guests: Helen Zaltzman is the host of The Allusionist.

If you read the title of this episode and cringed, you’re not alone. At Merriam-Webster, editors and lexicographers receive countless letters grousing about the addition of certain words to the dictionary. And here at Science Diction, we get our fair share of emails pointing out our linguistic missteps.  But the more you dig into the origins of words, the more you notice that when it comes to language, “correctness” is a slippery concept. In fact, some of our most beloved English words - nickname! newt! - were born of mistakes.  In this episode, Merriam-Webster lexicographers Emily Brewster and Peter Sokolowski explain the mistake-ridden origins of our words, how language evolves, and how wrong becomes right. Plus, we answer a listener question about the most exported word in the English language.

When the first COVID-19 vaccines were approved for emergency use last December, it felt like - at last! - our nightmare was nearly over. Then came reports of botched distribution efforts, from broken websites to factory mix-ups. Scientists created the vaccine in record time, but it was beginning to look like that might’ve been the easy part. But if you think vaccine distribution was a logistical nightmare in 2021, try doing it in the early 1800s. In 1796, Edward Jenner discovered that cowpox worked as a vaccine against smallpox. All you had to do was pop a cowpox sore on someone’s skin and transfer the lymph fluid (a.k.a. pus) into a cut on a second person. Soon, they'd develop a few sores, but when they recovered, they'd be immune to smallpox, a far more serious disease. This worked well enough for short distances, but when smallpox began to destroy Spanish colonies in the Americas, Spain had to figure out a way to move the vaccine across the ocean. Their solution was resourceful, effective, and very ethically dubious. Science writer Sam Kean brings us the story of the world's first vaccination campaign.

In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those  showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing extroverts of being shallow and incessantly chatty party monsters, and extroverts declaring introverts self-absorbed shut-ins who are just jealous because extroverts are actually happy. (A contention that studies support.) It all feels like a very 21st Century, internet-era drama. But the history of the dubious and divisive introvert-extrovert binary began 100 years ago, when Carl Jung fell out with Sigmund Freud, and tried to make sense of where they’d gone wrong. In the process, Jung coined a couple of new terms, and unleashed an enduring cultural obsession with cramming ourselves into personality boxes.

In 1953, in the coastal town of Minamata in Japan, locals noticed some cats were acting strangely—twitching, spinning in circles, almost dancing. The reality was far darker. What looked like dancing was really convulsions. The cats drooled, spun in circles, and flung themselves into the sea. The cause of this strange behavior, residents discovered, was mercury. Mercury—a silvery liquid, named for a quick-footed Roman God—has captivated humans since ancient times. It’s found in Egyptian tombs that date to 1500 BCE, and the first emperor of unified China believed it was the elixir of life. But what happens when it invades a town, and seeps into our brains?

Vervet monkeys steal it out of people's hands. Chimpanzees in Guinea are known to climb up palm trees and drink it. There’s even a theory that loving it was an important adaptation for our pre-human ancestors, that the smell of fermentation helped them track down very ripe, calorie-rich fruit.  Alcohol has been deeply ingrained in our lives from the beginning, possibly since before we were human. And while the drive to drink is older than civilization, many have worked hard to reign it in. In 1920s America, these desires clashed like never before. It’s a story of a battle between chemists, and the unthinkable lengths the U.S. government went to to try to pry away our favorite mind-altering substance.

In 1920, a Czech writer was stumped. He’d written a play about a future where machines that looked like people do our bidding. They were the perfect workers: obedient, hard working, and never demanded a pay raise. But what was the writer to call these marvelous machines? There wasn’t yet a word for this type of creation.  He had initially chosen labori, from the Latin for labor, but something about the word wasn’t quite right. It seemed...stiff, bookish. This play wasn’t just about machines who labored. It was about machines we exploited, relentlessly. And eventually, the writer landed on a word that fit better: Robot.  Robot comes from an old Czech word for drudgery and servitude. Though in his play - like so very many robo-dystopias to come - the writer showed that a mind we create to serve us, isn’t necessarily a mind we can control.

On December 5th, 2012, a bill landed on President Barack Obama’s desk, meant to do one thing: remove the word “lunatic” from the federal code. This is because in 2012, you could still find the word in laws about banking and controlling estates, among others. And not only was it offensive, it was antiquated—ancient, in fact. The word lunacy comes from luna—Latin for moon. This is because there was a time when we thought the power to change our moods and minds came from the sky.

In the late 18th century, a doctor showed up in Paris practicing some very peculiar medicine. He would escort patients into dimly lit rooms, wave his arms over their bodies, and touch them with a magnetic wand. Patients would react to these treatments violently: crying, sweating, convulsing or shrieking. But then they would emerge healed. According to the doctor anyway. Many believed he was a fraud, but despite his dubious methods, this doctor inadvertently gave us a new approach to healing—and a new word: mesmerize.
