You’ve seen it before. It’s that viral video of a spinning dancer or a static image of a colorful tree versus a gray, mechanical engine. The caption usually screams something like, "If you see the dancer turning clockwise, you’re right-brained and creative!" It’s a fun little internet distraction. We love categories. We love being told that our tendency to lose our car keys or our knack for poetry is hardwired into a specific hemisphere of our gray matter. But honestly? The left brain right brain picture test you just took on social media is mostly a lie.
That sounds harsh. I know.
But here’s the thing: your brain is way more interesting than a binary toggle switch. While these optical illusions and "personality quizzes" are great for a five-minute lunch break, they barely scratch the surface of how lateralization—the actual science of brain asymmetry—works. We’ve been fed a diet of pop psychology that suggests the left hemisphere is a cold, calculating spreadsheet while the right hemisphere is a barefoot artist painting at sunset. Reality is much messier. It’s also much more integrated.
The Myth of the "Creative" Right Brain
The obsession with the left brain right brain picture test started with genuine science that got telephone-gamed into oblivion. Back in the 1960s, neurobiologist Roger Sperry conducted "split-brain" experiments. He worked with patients who had their corpus callosum—the thick bundle of fibers connecting the two halves of the brain—severed to treat epilepsy.
Sperry discovered that the two halves did have different specialties. The left side usually handled language and logic; the right side was better at spatial recognition and face processing. He won a Nobel Prize for this in 1981.
Then, the self-help industry grabbed it.
Suddenly, every personality quirk was a result of "hemispheric dominance." If you liked math, you were stuck in your left brain. If you were "vibey" and liked music, you were a right-brain person. This is a massive oversimplification. In a healthy brain, the two sides are in constant, lightning-fast communication. You don't use "half" your brain to do anything. Even a simple task like talking involves both. The left side might pick the words, but the right side handles the intonation and the emotional context. Without both, you'd sound like a GPS navigation voice with no soul.
Why the Spinning Dancer Messes With Your Head
Let's talk about that dancer. It’s the most famous left brain right brain picture test out there. Created in 2003 by web designer Nobuyuki Kayahara, it’s technically a "reversible silhouette illusion."
Because the image lacks depth cues—there are no shadows or 3D markers—your brain has to make an executive decision about which way she’s spinning. If you see her turning clockwise, some bloggers claim you're a "right-brain" creative. If it’s counter-clockwise, you’re a "left-brain" analyzer.
Except, that's not what's happening.
Your perception of the dancer has everything to do with your visual processing and almost nothing to do with whether you’re good at algebra. It’s about "bistable perception." Your brain hates ambiguity. It picks a direction to make sense of the visual data. Research has shown that most people see her spinning clockwise because we have a "viewing-from-above" bias. We naturally assume we are looking down at the ground where she’s standing. If you can make her switch directions, congrats! You’ve just demonstrated "perceptual rivalry," not a secret talent for interior design.
The Real Science of Lateralization
If the "test" is fake, is the whole concept of left vs. right bunk? Not entirely.
Scientists call it lateralization. It’s real, but it’s subtle. For instance, about 95% of right-handed people have language processing localized in the left hemisphere. For lefties, it’s more diverse—some use the right, some use both.

Take a look at how we process music. Pop psych says music is "right-brained." Wrong. While the right hemisphere might handle the melody and timbre, the left hemisphere is often busy analyzing the rhythm and the structure. If you’re a professional musician, you actually use your left brain more when listening to music because you’re analyzing it like a language.
What a 1,000-Person Study Proved
In 2013, researchers at the University of Utah analyzed the brain scans of 1,011 people aged 7 to 29. They looked at "resting-state functional connectivity." Basically, they wanted to see if some people had more active networks on one side versus the other.
The result? Nothing.
Lead author Jeff Anderson, M.D., Ph.D., noted that while some functions are localized to one side, there was no evidence that individuals had a stronger "overall" left-side or right-side network. You aren't a "left-brained person." You are a person with a brain that uses different specialized modules depending on the task at hand. The left brain right brain picture test might tell you how you perceive a silhouette, but it won't tell you if you're better suited for law school or art school.
Why We Love These Tests Anyway
We crave identity. It’s human nature.
Categorizing ourselves into "Left Brain" or "Right Brain" feels just like checking our astrological sign or our Myers-Briggs type. It gives us a framework to explain our weaknesses. "Oh, I’m just so right-brained, I can’t do taxes!" It’s a convenient excuse. But it’s also limiting.

When you tell a kid they are "right-brained," they might stop trying in math class because they think their biology is against them. That’s dangerous territory. The brain is incredibly plastic. It changes based on what you do. If you practice logic, those neural pathways get stronger. If you paint every day, your visual processing centers evolve. You aren't born with a "side" that dictates your destiny.
The Problem With "Brain-Based" Learning
This myth has leaked into schools, too. You’ll find teachers trying to "teach to the right brain" by using more pictures and less text. While using visuals is a great teaching tool for everyone, it’s not because half the class has a dominant right hemisphere.
Educational psychologists call these "neuromyths."
Believing in a left brain right brain picture test as a diagnostic tool for learning styles is actually counterproductive. According to the OECD (Organisation for Economic Co-operation and Development), these myths can lead to ineffective teaching strategies. The best way to learn is "multi-modal"—using your whole brain. Read it, see it, do it. Don't silo your mind into a box it doesn't actually live in.
How to Actually "Test" Your Brain
If you really want to understand your cognitive profile, skip the Facebook quizzes. You want to look at executive function and cognitive flexibility.
Can you switch between tasks easily? That’s your frontal lobe working.
Can you remember a string of numbers? That’s working memory.
Can you recognize a friend’s face in a crowd? That’s your fusiform face area.
None of these are "left" or "right" in a vacuum. They are parts of a massive, interconnected web. If you want to improve your "right brain" (creativity), don't look at pictures of spinning ladies. Go learn a new skill that challenges your spatial reasoning. If you want to boost your "left brain," dive into a complex logic puzzle or start learning a new language.
Real Insights to Take Away
- Ditch the labels: Stop calling yourself "left-brained" or "right-brained." It’s a self-imposed ceiling on your potential.
- Use the whole thing: Creative problem-solving requires both logic (to define the problem) and intuition (to find novel solutions).
- The tests are games: Enjoy the left brain right brain picture test for what it is—a trick of the light and a quirk of the eye, not a neurological map.
- Neuroplasticity is king: Your brain is a muscle. It doesn't matter which "side" you think you favor; you can develop the other side through practice.
Next time you see an image that claims to reveal your inner psyche based on whether you see a duck or a rabbit, remember: it’s your brain being efficient, not your personality being revealed.
To actually sharpen your mind, focus on sleep, aerobic exercise, and lifelong learning. These are the only "brain hacks" that actually hold up under a microscope. If you’re curious about how your specific cognitive strengths stack up, consider looking into legitimate neuropsychological assessments like the WAIS-IV (Wechsler Adult Intelligence Scale), which measures actual performance across various domains rather than relying on optical illusions.

Stop trying to figure out which side of your brain you use and just start using all of it. The complexity of your bilateral mind is much more impressive than any "test" you'll find in a sidebar ad. Take the "results" of these picture tests with a massive grain of salt, or better yet, ignore the results and just appreciate the weird way your eyes and brain coordinate to make sense of a chaotic world. That’s where the real magic is.
