Imagine you're at a party, or hosting one for your kids, and a group of guys introduce themselves as Tyler, Kyler, and Skyler. "Omigosh, that is seriously kind of amazing -- we're Elsie, Kelsey, and Chelsea! You guys just missed Kennedy and Serenity, but I'm sure they'll be back soon..."
I don't know about you, but when there are so many made-up names that rhyme with each other, it doesn't create an it-just-happened-that-way kind of delightfulness. It sounds hamfisted, like forcing a rhyme between "mobster" and "lobster". The evident self-consciousness just makes the whole thing seem phony and off-putting. It's campy, not charming. (By the way, those are all real names in the top 1000 for babies born in 2011.)
I've been looking through how similar the popular names sound over time, and once it's all collected and analyzed, I'll hopefully write something up here. But to show how wildly these things can cycle, let's take a quick look at four years that began four iconic decades -- 1920, 1950, 1980 and 2010. Below are the names in the top 100 for girls that rhyme.
1920 -- 19 rhyme
Jean, Irene, Eileen, Pauline, Maxine, Kathleen, Geraldine
1950 -- 37 rhyme
Ann(e), Dian(n)e, Joann(e), Suzanne
Jean(ne), Irene, Eileen, Kathleen, Christine, Darlene, Maureen
1980 -- 30 rhyme
Misty, Christy (Kristy)
Tina, Gina, Katrina, Christina (Kristina)
2010 -- 36 rhyme
Chloe (Khloe), Zoe(y)
Brianna, Gianna, Arian(n)a
Hannah, Anna, Savannah
Isabella, Ella, Gabriella, Bella, Stella
Hailey, Kaylee, Bailey
Layla, Kayla, Makayla
Mia, Leah, Maria, Aaliyah, Amelia, Valeria, Sophia (Sofia)
When you weight the names not only by whether or not they have a rhyming partner, but by how many such partners they have (i.e. just twins or octuplets), the picture is even clearer that 1950 and 2010 were high points in mindless conformity, while 1920 and 1980 were low points. I qualify "conformity" with "mindless" to distinguish it from a meaningful, heart-felt kind. Meeting the neighbor's kids who are named Huey, Dewey, and Louie doesn't fill me up with fellow-feeling -- it just sounds goofy. If anything it's alienating, making me wonder what planet I've landed on.
It's a cheap display of willingness to play on the same team. Actively keeping an eye on each other's kids, hosting them at sleepovers, and sending them around to trick-or-treat would be costly and honest displays of team-mindedness. When people want to cocoon, they have to at least hold up a fig leaf of community spirit, so we get these overly eager, almost caricatured forms of togetherness.
Treat this as news you can use, and hold off having kids until this index starts to fall for awhile. Then you'll know that the rest of society is backing away from hive-like social behavior and returning to neighborly trust, making way for communities worth raising children in.
