Is "Left-brained people are logical, right-brained people are creative" true?
Somewhere along the way, a real but narrow finding about brain hemispheres got flattened into a personality quiz: are you logical and left-brained, or artsy and right-brained? Magazines ran the quiz, teachers repeated the split, and it felt like neuroscience because it borrowed neuroscience vocabulary. Actual brain scans tell a much less tidy story. Nearly every task, whether it's solving an equation or composing a melody, lights up both hemispheres working together, with no clean division of labor between them.

What you were taught
Left-brained people are logical, right-brained people are creative
What we know now
Brain imaging shows both hemispheres work together for most cognitive functions, and the left/right brain divide is oversimplified.
Was "Left-brained people are logical, right-brained people are creative" taught in school?
Yes — and not as a joke question on a quiz. This psychology claim showed up in textbooks, worksheets, and classroom posters through the 1990s, which is why so many people still remember it as settled fact long after the science moved on.
Is "Left-brained people are logical, right-brained people are creative" true?
No. Brain imaging shows both hemispheres work together for most cognitive functions, and the left/right brain divide is oversimplified. If you want the primary citation, start with Scientific American - The Truth About the Left Brain/Right Brain Relationship.
When was this understanding updated?
The evidence had largely shifted by around 2013. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
