For decades, we’ve divided our minds down the middle. “Left-brain” types are analytical, logical, and buttoned-up. “Right-brain” types are creative, intuitive, and a little messy. This tidy split has shown up everywhere—from pop psychology books to corporate training sessions to memes about your “creative” friend who can’t do math.
But here’s the reality: the brain doesn’t work that way. Not even close. And clinging to the left-brain/right-brain myth does more than misinform—it actually limits our understanding of how creativity really works.
Innovation isn’t the property of one hemisphere. It’s a dynamic, full-brain process that pulls from logic and imagination, discipline and inspiration, memory and abstraction. The sooner we let go of the myth, the sooner we can unlock the kind of creativity that changes everything.

Where the Myth Came From
The origin of the left-brain/right-brain theory traces back to research in the 1960s and ‘70s by neuropsychologist Roger Sperry and his colleagues, who studied patients with split corpus callosums (the thick bundle of fibers connecting the two hemispheres). These studies revealed that the left and right hemispheres do, indeed, process information differently.
The left hemisphere was shown to be more involved in language processing, while the right played a stronger role in spatial and nonverbal information. Over time, these findings were oversimplified—and eventually morphed into a pop-culture myth: that people are either left-brained or right-brained, with corresponding talents and traits.
It’s a neat narrative. But it’s wrong.
Creativity is a Whole-Brain Operation
Neuroscientific studies using modern imaging techniques—like fMRI and PET scans—show that both hemispheres are deeply involved in creative thinking. Whether you’re composing music, writing a screenplay, designing a product, or solving a technical problem, your brain recruits multiple regions across both sides.
Take the process of writing a novel. You’ll draw on:
- The left hemisphere for grammar, word retrieval, and linear story structure
- The right hemisphere for tone, metaphor, and emotional resonance
- The prefrontal cortex for planning and attention
- The limbic system for emotional connection
Even activities traditionally seen as “purely creative” light up logic centers. And analytical work often benefits from imagination. That breakthrough marketing strategy? It needed data—but also a bold narrative. That new app interface? It took code—and a strong aesthetic.
Why the Myth Still Persists
Part of the appeal of the left/right-brain story is that it gives people an identity. “I’m just not creative—I’m left-brained.” Or, “I’m a creative type—I can’t handle numbers.” These labels feel safe. They offer an excuse to stay in our comfort zones.
But real growth happens when we challenge that story. You can be an artist who learns statistics. A scientist who writes poetry. A business leader with a killer eye for design. Not only is this possible—it’s how innovation thrives.
Our cultural moment demands hybrid thinkers: people who can synthesize across domains, connect unrelated ideas, and move fluidly between analysis and intuition. That’s not left-brain or right-brain. That’s full-brain.
Brain Supplements: Supporting Cognitive Versatility
If creativity involves coordination across brain regions, then supporting that connectivity is key. This is where brain supplements—also known as nootropics—can be useful allies. Certain formulations are designed not just to boost focus or memory in isolation, but to improve overall brain communication and integration.
Nootropic ingredients like Lion’s Mane mushroom and phosphatidylserine may support neural plasticity—the brain’s ability to form new connections. Others, like Alpha-GPC or Acetyl-L-Carnitine, are known for aiding the synthesis of acetylcholine, a neurotransmitter vital for learning and synaptic signaling. When the brain’s networks fire more efficiently, you’re better equipped to bridge the gap between logic and imagination, pattern and play.
These supplements aren’t a shortcut to brilliance, but they can form part of a routine that supports the kind of mental agility required for modern creative work.
Training Both Sides of the Mental Circuit
You wouldn’t train just one side of your body at the gym—so why train just one side of your mind? To foster holistic creativity, you need to engage both the structural and the spontaneous, the deliberate and the intuitive. That might mean:
- Analytical creatives: Taking improv classes, exploring abstract painting, or writing fiction
- Intuitive thinkers: Studying logic puzzles, learning basic programming, or taking a statistics course
- Daily mental cross-training: Mixing structured tasks (like budgeting) with open-ended play (like mind mapping or doodling)
This blend builds what educators call cognitive flexibility—the ability to switch between mental modes, perspectives, and problem-solving strategies. It’s not only good for creativity—it’s essential for navigating complexity in work, relationships, and decision-making.
Rethinking the Way We Think
Letting go of the left-brain/right-brain myth isn’t about erasing personality differences. Some people do think more linearly. Others are more freeform. That’s part of the rich diversity of minds. But those preferences aren’t destiny. They’re starting points.
Innovation, in its truest form, demands integration. It calls on us to think beyond categories, both in the world and in ourselves. So the next time someone tells you they’re not the “creative type,” remind them: creativity isn’t a side of the brain. It’s the way the whole brain works—when we let it.
It’s not about being left-brained or right-brained. It’s about being fully minded.
