The Left Brain vs. Right Brain Myth: Why It’s Time to Ditch This Outdated Science

March 17, 20252 min read

What Science Actually Says (Spoiler: You Use Your Whole Brain)

Your brain doesn’t work in halves. Both hemispheres are constantly communicating and working together, all the time.

Here’s what the research actually shows:
✅ Creativity isn’t just “right-brained.” Studies using fMRI scans show that problem-solving, imagination, and artistic skills activate both hemispheres.
✅ Logic and analysis aren’t just “left-brained.” Even when processing numbers or language, both sides of the brain light up.
✅ Your brain is an interconnected network. You don’t “use one side more” than the other, every thought and action requires input from both hemispheres.

The left-brain/right-brain idea is as outdated as floppy disks and fax machines (which, if you saw my last post, you’ll know I have opinions about).

Why This Myth is Holding You Back

If this was just a harmless little misunderstanding, I wouldn’t care. But here’s why it actually matters:

📌 It stops people from trying. How many people have avoided learning something new because they think they’re “just not wired that way”?

📌 It creates self-limiting beliefs If you’ve spent your life believing you’re “not a numbers person” or “not creative,” you might not even try to develop those skills.

📌 It reinforces a fixed mindset. And here’s the real kicker your brain is incredibly adaptable. You are constantly learning, changing, and rewiring. The idea that you’re stuck in a thinking style? It’s just not true.

So, What Now?

If you’ve ever labeled yourself as “left-brained” or “right-brained”, it’s not your fault. We’ve all been told this at some point.

But now you know better. So maybe the real question is…

What would you have done differently if you never believed this myth in the first place?

Because your brain isn’t a box. And you were never meant to live in one.

Have you ever been told you’re “just not wired” for something? What did it stop you from doing? Let’s talk.
