Baby talk may sound kind of weird, but it's actually an awesome evolutionary phenomenon.

A lot of us find baby talk to be very ... weird.

You know, that kind of high-pitched singsong kind of lingo that only seems to occur around small babies or funny-looking dogs? It's totally weird. But we all do it.


"Who-o-o's a good boy? Who is? Who is?"

It just seems to happen, like there's some sort of switch in our brain that turns on and transforms us from articulate human beings into human beings who sound like they swallowed an Auto-Tune machine.

Baby talk isn't limited to a handful of languages, either — it's been observed nearly everywhere — including in English, Arabic, Hindi, and Mandarin-speaking cultures, to name just a few.

A lot of scientists, however, don't find baby talk weird at all. They find it absolutely fascinating.

Language is something we use every day, but it's one of the most interesting puzzles in biology. Figuring out how babies learn to talk can help us understand how our own brains process language and maybe even how language evolved in the first place.

Scientists have found that using baby talk might actually help infants learn words faster.

Of course, scientists usually don't call it "baby talk," preferring somewhat more clinical terms like "parentese," "motherese," or "infant-directed speech."

But one study from the University of Washington found that 2-year-olds whose parents regularly had long conversations with their kids in parentese had more than double the vocabulary of kids who got the least exposure to it.

Why? It turns out babies like the singsongy tone of voice that comes with baby talk.

It's not the made-up words, like goo-goo ga-ga; instead, it's that weird tone of voice we use. There's something about that pattern of long, exaggerated sentences ("Helloooo, lil' bay-bee" vs. "Greetings, small infant," or just "Hey", for example) that babies seem to tune in on.

The high-pitched sounds we use when speaking in baby talk appear to be better at keeping babies' attention than when we speak with more normal intonation and inflections.

Those big, grand exaggerations we tend to use in baby talk also help convey emotion better than our normal adult speech.

Imagine trying to learn a new language — when it comes to figuring out which words are happy and which are sad, would you rather talk to Miss Piggy, whose tone of voice always lets you know what she's feeling, or Sam the Eagle, whose voice remains the same no matter what he's talking about?

Scientists also think the repetitive sounds used when speaking in baby talk (think "ma-ma," "da-da," or "choo-choo") might also help cement the words in a baby's brain.

In a recent study from the University of Edinburgh, scientists put 18-month-old kids in a room with a computer screen.

Something like this, anyways...

In each test, they showed each of the kids two unfamiliar objects. One object was given a repeating made-up name, like "nee-nee." The other object's made-up name didn't have a repetitive sound.

When the researchers later tested the kids again, they found the kids were better at remembering the name of the object with the repeated syllable.

So, parents and friends of parents with infants, now that you know this, go ahead and your singsongy baby talk flag fly.

You might feel weird using baby talk or maybe other people think you're weird for doing so — but armed with this knowledge, you can go right ahead and embrace the baby talk. After all, no matter what other people think, you know what you're really doing.

You're helping your kid learn to speak.

Glenda moved to Houston from Ohio just before the pandemic hit. She didn't know that COVID-19-related delays would make it difficult to get her Texas driver's license and apply for unemployment benefits. She quickly found herself in an impossible situation — stranded in a strange place without money for food, gas, or a job to provide what she needed.

Alone, hungry, and scared, Glenda dialed 2-1-1 for help. The person on the other end of the line directed her to the Houston-based nonprofit Bread of Life, founded by St. John's United Methodist pastors Rudy and Juanita Rasmus.

For nearly 30 years, Bread of Life has been at the forefront of HIV/AIDS prevention, eliminating food insecurity, providing permanent housing to formerly homeless individuals and disaster relief.

Glenda sat in her car for 20 minutes outside of the building, trying to muster up the courage to get out and ask for help. She'd never been in this situation before, and she was terrified.

When she finally got out, she encountered Eva Thibaudeau, who happened to be walking down the street at the exact same time. Thibaudeau is the CEO of Temenos CDC, a nonprofit multi-unit housing development also founded by the Rasmuses, with a mission to serve Midtown Houston's homeless population.

Yesterday I was perusing comments on an Welcometoterranova article about Joe Biden comforting the son of a Parkland shooting victim and immediately had flashbacks to the lead-up of the 2016 election. In describing former vice President Biden, some commenters were using the words "criminal," "corrupt," and "pedophile—exactly the same words people used to describe Hillary Clinton in 2016.

I remember being baffled so many people were so convinced of Clinton's evil schemes that they genuinely saw the documented serial liar and cheat that she was running against as the lesser of two evils. I mean, sure, if you believe that a career politician had spent years being paid off by powerful people and was trafficking children to suck their blood in her free time, just about anything looks like a better alternative.

But none of that was true.

It's been four years and Hillary Clinton has been found guilty of exactly none of the criminal activity she was being accused of. Trump spent every campaign rally leading chants of "Lock her up!" under the guise that she was going to go to jail after the election. He's been president for nearly four years now, and where is Clinton? Not in jail—she's comfy at home, occasionally trolling Trump on Twitter and doing podcasts.

Racist jokes are one of the more frustrating manifestations of racism. Jokes in general are meant to be a shared experience, a connection over a mutual sense of humor, a rush of feel-good chemicals that bond us to those around us through laughter.

So when you mix jokes with racism, the result is that racism becomes something light and fun, as opposed to the horrendous bane that it really is.

The harm done with racist humor isn't just the emotional hurt they can cause. When a group of white people shares jokes at the expense of a marginalized or oppressed racial group, the power of white supremacy is actually reinforced—not only because of the "punching down" nature of such humor, but because of the group dynamics that work in favor of maintaining the status quo.

British author and motivational speaker Paul Scanlon shared a story about interrupting a racist joke at a table of white people at an event in the U.S, and the lessons he drew from it illustrate this idea beautifully. Watch:
