Why some baby names spike for a decade and then vanish

HostIt's funny how you can almost guess when someone was born just by hearing their name. If I meet a Jennifer or a Jessica, I have a pretty good guess of what their high school photos look like. But it makes me wonder why a name that everyone loves for ten years suddenly starts to feel so dated. Why do we all seem to turn on a name at the exact same time?

GuestIt's a lot like how a song on the radio gets played until you can't stand it anymore. Names follow these waves. For a long time, names were very stable. You would name a child after a father or a grandmother, and those names stayed in the family for hundreds of years. But today, names move through the world more like fashion or catchy tunes. They have a life cycle. They start out as something fresh and different that only a few people are using. Then, more people hear them and think they sound cool and new. But once a name reaches a certain peak, it hits a wall. It stops being a name and starts being a label for a specific slice of time.

HostBut wait, it feels like every kid in a classroom today has a totally different, unique name. If things are moving faster now, would we not see more people with the same names, not fewer?

GuestThat's the strange part of how this works. We're actually in a time where people are more afraid of being boring than ever before. Parents go out of their way to find something that stands out. But the problem is that millions of parents are all looking for that same feeling of being unique at the very same time. They all look at the same lists and watch the same shows. So, you might think you're being bold by picking a name like Luna or Harper, but you're actually part of a huge group of people who are all having that same original thought at once. It's a bit of a trap. You pick a name to be different, but because so many other people had that same goal, you end up creating a new trend that will eventually feel just as stuck in time as the names from forty years ago.

HostI still find it hard to see why we do that. If I go to a party and see five other people wearing the same shirt as me, I want to go home and change. Why do parents keep picking a name once they see it climbing the charts?

GuestWell, most people don't actually want to be the very first person to do something. Being the first person to use a name feels risky. It feels weird or out of place. Most of us wait until we have heard a name a few times before it starts to sound right to our ears. There's this sweet spot where a name sounds familiar enough to be pretty, but not so common that it feels tired. The trouble is that by the time a name feels safe and stylish to most people, it's already on its way to being overused. It's like a bell curve. Once it hits the top ten list, the cool factor is basically gone. The people who want to be ahead of the curve move on to something else, and the name starts its long slide down into being a grandma name.

HostDoes pop culture play a bigger role than we think? I mean, I know a lot of people blamed certain movies or singers for name spikes in the past.

GuestIt definitely does, but not always in the way you would expect. A big movie star might make a name jump up for a year or two, but those names often crash the hardest. There's something called the Tiffany Problem. It's an idea that writers talk about. Even though the name Tiffany has been around since the middle ages, if you put a person named Tiffany in a story about knights and castles, it feels wrong. It feels like she stepped out of a mall in the nineteen eighties. Some names get anchored to a specific moment so tightly that they can't breathe on their own anymore. If a name is tied to a specific character in a huge TV show, it can feel like a costume rather than a real name. Parents eventually shy away from that because they don't want their kid to be a walking billboard for a show that ended twenty years ago.

HostBut some names do come back. My friend just named her baby Hazel, and I remember my great aunt had that name. It doesn't feel like a mall name at all.

GuestThat's because of what people call the hundred year rule. For a name to feel fresh again, the generation that originally used it has to be mostly gone. We tend to dislike the names of our parents and their friends because those names feel like old people names. They feel like the people who gave us chores or worked in boring offices. But names from our great grandparents feel different. They feel vintage and romantic because we don't have those same personal ties to them. A name like Hazel or Alice can come back because it has been away long enough for us to forget the people who wore it when it was common. It feels like a blank slate again.

HostIt's wild to think that our tastes are so tied to who's still walking around.

GuestIt really comes down to the sounds too. We go through phases where we love certain vowel sounds or endings. For a while, every popular boy name had to end with a certain sound, like Jayden or Kayden or Aidan. It felt fresh because it was different from the traditional names like John or Robert. But when twenty different names all share that same rhyming sound, they all start to blur together. They become the sound of that decade. Eventually, people get tired of the rhyme and move toward something completely opposite, like names that are very short or names that sound more rugged. We're always running away from whatever just finished being popular.

HostThe big question is whether the internet has changed this for good. With everything moving so fast now, will any name ever stay popular for more than a few years?

GuestWe might be moving toward a world where names are more like internet memes that flare up and disappear in a blink, leaving us with a patchwork of names that tell a very specific story about exactly when we were born.

HostThose names are basically time stamps, and it's a funny thought that the unique choice we make for a baby today is the very thing that will tell the whole world their age fifty years from now.

GuestA person can change their clothes or their hair, but that name stays as a permanent reminder of what their parents thought was cool in one specific summer.

HostHigh school photos might fade, but a name like Tiffany or Jayden is a bell that keeps ringing for a lifetime.
