Why We Still Think People Are Left-Brained or Right-Brained

Good Morning.

Somewhere along the way, the brain became a personality test.

The left side was assigned logic, language, and order. The right side got creativity, intuition, and imagination. People began describing themselves accordingly. Accountants were left-brained. Artists were right-brained. A person who enjoyed both spreadsheets and painting apparently had some explaining to do.

The idea wasn’t entirely invented. The brain’s two hemispheres do show meaningful differences. Language is more strongly associated with the left hemisphere in most people, while certain aspects of spatial attention rely more heavily on the right. Studies of patients whose connection between the hemispheres had been severed revealed just how specialized some functions could be.

Popular culture took those findings much further. Differences between two sides of the brain became differences between two kinds of people.

Brain imaging hasn’t supported that conclusion. In one study, researchers examined brain scans from more than 1,000 people and found no evidence that individuals consistently favored one hemisphere in a way that produced a left-brained or right-brained personality.

Yet the idea has been difficult to dislodge.

Part of its appeal may be how easily it turns complexity into recognition. People do vary in their abilities and preferences. Some enjoy precision. Others are drawn to possibility. Placing those differences on opposite sides of the brain gives them a physical explanation that feels both scientific and personal.

It also offers something many personality systems provide: a category that helps us describe ourselves quickly. The label may be inaccurate, but the experience behind it can feel true.

The actual brain asks more of us. Writing a poem involves language, memory, rhythm, judgment, and revision. Solving a mathematical problem can require visual imagination and an intuitive sense of where to look next. Activities we classify as logical or creative rarely remain on their assigned side.

The brain does divide some of its work. It also depends on constant communication across those divisions.

Perhaps that is harder to fit into a quiz. It is also a much better description of how people think.

Longevity

The Long Game
One small thing for a longer life

Did You Know

A pound of muscle and a pound of fat weigh exactly the same, but muscle is denser and occupies less space. That’s why someone can lose fat, gain muscle, and notice that their clothes fit differently even when their weight barely changes.

As we age, maintaining muscle becomes increasingly important for strength, balance, recovery, and independence. The number on the scale may be useful, but it doesn’t always reveal what the body has gained or lost.

Movement is one of the six factors that shape how well we age. The Worthyest Longevity Index measures all six in 4 minutes and gives you a personalized score.

Why Our Bodies and Minds Respond the Way They Do

Some experiences are so common that we rarely stop to ask what's behind them. This collection looks at why mosquitoes prefer some people, warning signs that can precede a heart attack, and why the passage of time seems to speed up as we get older.

Time Flies by Faster as We Get Older. Here's Why.
A year can feel remarkably different at 60 than it did at 10. Psychologists have several explanations for why our perception of time changes with age and what may influence how quickly life seems to pass.

The 4 Biggest Early Warning Signs Before a Heart Attack
A heart attack doesn't always begin with the sudden chest pain people expect. Cardiologists explain several symptoms that can appear beforehand and why recognizing them deserves attention.

So THAT'S Why Mosquitoes Bite Some People More Than Others
If mosquitoes seem to find you no matter who else is around, there may be biological reasons for it. Researchers have identified several factors that can make certain people especially attractive to them.

What Everyday Foods Can Do

Some foods earn attention not because they're exotic, but because of what they may contribute when eaten regularly. This collection looks at a snack that supports metabolism, the relationship between omega-3s and mental health, and what beet juice may do for blood pressure.

Can Omega-3s Support Better Mental Health?
Omega-3 fatty acids are well known for their roles in heart and brain health. Researchers have also been studying their connection to mood and mental well-being, with evidence suggesting some potentially useful effects.

The #1 Snack to Eat to Support Your Metabolism, According to Dietitians
Metabolism is influenced by far more than any single food, but the right snack can provide nutrients that help support it. Dietitians recommend one familiar option that brings several nutritional advantages together.

What Happens to Your Blood Pressure When You Drink Beet Juice Regularly
Beets contain compounds that affect how blood vessels function, which has made beet juice an interesting subject for cardiovascular research. Here's what studies suggest may happen to blood pressure when it becomes a regular part of the diet.

Final Note

This is what we leave you with. A thought to end the day, carry in your pocket, or come back to later. Nothing big. Just something to reflect on.

The Future Rarely Looks Like the Future

The future almost always arrives wearing different clothes than we imagined.

We tend to imagine the future through whatever feels new today. But when it finally gets here, the biggest changes often look ordinary. They become part of the background, woven into routines we barely think about. The strange thing about the future is how quickly it stops feeling like one.
