Jeremy informs his friend that most people only use around
ten percent of their total brain power. How should his friend
reply to this claim?
"That sounds interesting, but I'll only believe
it's true if I hear it from my psychology
"That is a controversial idea among
psychologists and is currently hotly debated in
the field."
"That sounds like pseudopsychology. In fact,
there is no evidence that people only use ten
percent of their brains."

Answer :

Final answer:

The belief that we only use 10% of our brains is a myth debunked by neurologists, and there is no scientific basis for this claim.


The claim that humans only use 10% of their brains is a myth that has been debunked by neurologists like V.S. Ramachandran. Every part of the brain is utilized, just not simultaneously, similar to how a traffic light uses all its colors at different times. There is no scientific evidence supporting the notion that we only use a small portion of our brains.
