Is the left brain/right brain myth true?

The concept of being "left-brained" or "right-brained" is largely a myth. While there are some functions in the brain that are lateralized to the left or right hemisphere, such as prosody (the lilting and falling of speech) and aspects of language, the popular notion that some people are more logical and others more emotional based on brain hemisphere dominance is not supported by scientific evidence.

Andrew Huberman clarifies that the idea of left-brained and right-brained personalities does not have a solid scientific basis. Instead, both hemispheres interact and contribute to various cognitive functions and learning processes, such as speech, mathematics, and language learning. Increased connectivity between the two hemispheres, mediated through the corpus callosum, enhances overall brain circuit capacity rather than influencing emotional or logical capacities specifically 1.

He also adds that while certain brain functions show some lateralization, the exaggerated differences portrayed in popular psychology about one hemisphere being responsible for logic and the other for emotions are incorrect. The real scientific evidence paints a more integrated and interconnected picture of hemispheric functions 2.
