Why You May Have Heard Humans Only Use 10% of the Brain and Why That's Wrong

Debunking the "10 percent" myth

An individual who has suffered brain damage will be unable to do certain things as a result of that damage. If the 10 percent myth were true, damage to about 90 percent of the brain wouldn't affect daily functioning.

But studies show that damaging even a small part of the brain can interfere with a function. Damage to the Broca's area prevents proper formation of words, but comprehension of language remains intact.

Different learning styles

Systematic studies of learning styles have consistently found no evidence or very weak evidence to support the idea that matching the material to a student’s learning style is more effective.

There is no conclusive evidence that people preferentially use the left or right hemisphere.

Certain functions are processed more by one region of the brain than others, and this is known as lateralization. But we all use our entire brain equally.

The left/right brain hypothesis

The theory that most people are either dominantly analytical (and left-brained) or creative (and right-brained) is false.

The two hemispheres of the brain are linked and communicate extensively together; they do not work in isolation. 

Recent studies suggest that engaging all the senses in a variety of ways (for instance, audiovisual and tactile) can help employees retain new content.
