It’s science: only children are more likely to be creative thinkers

Growing up solo leads to measurable differences in brain development that makes only children think differently than kids with siblings.

It’s science: only children are more likely to be creative thinkers

As a one-and-done mom of an only child, I’m familiar with the stereotypes. I’ve been warned my son will grow up to be lonely and selfish, and while there may be a kernel of truth to the popular notion that only-children are more likely to be narcissistic, the latest neuroscience suggests they’re actually more likely to be creative thinkers.


A growing body of research on only-children indicates that there are plenty of cognitive benefits from this kind of childhood, and according to a study published in the journal Brain Imaging and Behavior earlier this year, growing up solo leads to measurable differences in brain development that makes only-children think differently than kids with siblings.

Researchers at Southwest University in China tested hundreds of college-age young adults for IQ, creativity and personality traits and looked at the participants’ brains using MRI machines.

What they found was that the brain structures of only-children and those with siblings are visibly different.

The MRI results showed differences in gray matter volume: The brains of only-children had more volume in an area linked to language perception and processing and less volume in an area associated with personality and social behavior.

The cognitive tests backed up what the researchers saw in the MRI machines.

While there was no difference in the IQ scores, the only-children’s test results indicated higher levels of one measure of creative thinking, flexibility, and lower levels of agreeableness than those who grew up with siblings.

Basically, whether or not a kid is raised with siblings does impact their brain development. Neither outcome is necessarily better, but they are different.

According to the study’s authors, there’s still more work to be done before science can say exactly why the brains of solo kids are different, but it’s possible that the higher score on flexibility may be due to parents having more time for, and higher expectations of, only-kids.

Previous studies point to academic benefits of being having one’s parents full attention. According to a meta-analysis of more than 100 studies of only-children, parent-child relationships are an important factor in why only-children surpass most peers (the exceptions being firstborns and people from two-child families) on achievement and intelligence tests.

The research indicates that only-children are like firstborns in that they’re achievement-oriented, but that the stereotypes that paint them as smart yet lonely are unfounded. They’re no less sociable or more neurotic than other kids, just maybe a little more flexible and creative in their thinking.

Products that solve your biggest breastfeeding challenges

Including a battle plan for clogged ducts!

When expecting a baby, there is a lot you can test-run in advance: Take that stroller around the block. Go for a spin with the car seat secured in place. Learn how to use the baby carrier with help from a doll. But breastfeeding? It's not exactly possible to practice before baby's arrival.

The absence of a trial makes it all the more important to prepare in other ways for breastfeeding success—and it can be as simple as adding a few of our lactation aiding favorites to your registry.

21 questions to ask your partner instead of, “How was your day?”

2. If you could do any part of today over again, what would it be?

After a long day of doing seemingly everything, when our partners get home it kind of becomes a habit to ask, "How was your day?" In between prepping dinner, handing off the kids, finishing your own work, we don't exactly get much value from this question. Sure, it may open up the opportunity to complain about that awful thing that happened or excitedly share that presentation you killed at work—but it usually stops there.

I could do a better job of really talking in my relationship. After 12 years and two kids, sometimes all we can come up with post bedtime routine is, "You good? I'm good. Fire up the Netflix."
