Left-Brained vs. Right-Brained: Myth Debunked for Both Men and Women

The idea that people are either "left-brained" (logical, analytical) or "right-brained" (creative, intuitive) is a persistent neuromyth with no scientific basis.

• Functional MRI and PET studies show bilateral engagement for virtually all complex tasks.
• Language lateralization (usually left) and spatial attention (usually right) are specific functions, not global personality types.
• No study has found a correlation between hemispheric dominance and personality traits in men or women.

Cognitive style differences exist but arise from distributed network efficiency, not hemispheric dominance. The myth likely persists due to oversimplified pop-psychology interpretations of split-brain research.
