FALSE — NASA Study Does NOT Prove 10% Brain Myth

Verified on April 1, 2026

The idea that we only use 10% of our brain is a century-old myth. Recent NASA research actually focuses on how spaceflight physically shifts the brain, not how much of it we use.

How strongly independent, cited sources support this verdict.

Claim reviewed

A new NASA study allegedly proves that humans only use 10% of their brains.

Analysis summary

The claim is a long-standing myth; recent NASA-funded research actually focuses on physical brain shifts in space, not usage percentages, and confirms humans use 100% of their brain capacity.

Evidence profile

56 / 100 weighted evidence score H:0 / M:2 / L:0

Key findings

  • Modern neuroscience, supported by fMRI and PET scans, shows that humans use virtually 100% of their brains, even during sleep or simple tasks.
  • A recent NASA-funded study published in March 2026 actually investigated how the brain physically shifts and deforms within the skull during spaceflight, which has no relation to the 10% usage myth.
  • The '10% myth' is a century-old misconception likely originating from misquoted 19th-century psychologists and has been repeatedly debunked by the scientific community.
