The problem is that some of what got burned into our brains simply wasn’t right, or has since been dismantled by better research. After 50, it’s worth taking a second look at a few of the big ones.
You Only Use 10% of Your Brain
This common classroom claim has been debunked by neuroscientists for years. In reality, brain imaging shows that virtually all parts of the brain have identifiable functions, and even when you’re resting or asleep, your brain is still active in complex ways. The myth likely started as a loose metaphor for human potential and somehow made the leap into science class as literal fact.
Research shows that the brain uses about a fifth of the body’s total energy, and experts at institutions like Johns Hopkins have noted that humans “use virtually every part of the brain.” Technologies like PET scans have made this crystal clear. Positron Emission Tomography scans changed the way we understand the human brain, and they confirm that all humans are using the full extent of it.
