Anyone who has ever taken any sort of psychology class can tell you that the 10% myth is absolutely incorrect.

the 10% myth was basicly to tell people that if we used the full power of the brain we could teleport ourselves, travel through time, etc...

not too long ago, a movie was released called '' Limitless ''

its about a guy that takes pills to let himself access 100% of hes brain

here's the trailer Click Me

Unless you provide a source we'll have to assume you've come up with that yourself.

Although if we really could tenfold our working capacity to a given task, it would provide a much better outcome; I don't see a reason why we would be able to teleport ourselves or travel through time- except inside our consciousness.

Also, what Hyde said.

i saw a long time ago i dont remember the source sorry.
the teleport/travel through time are just examples

it basicly means that the brain at full power would be capable of extraordinary things.
have you ever heard of the terms telekinesis for example?
control objects with your mind.

there isnt any proof but there are people who think that through meditation and relaxing they can enter a state of mind that will let you do "impossible" stuff.

human brain is a mistery

the ancient man created tools (spears for example) to hunt animals.
the modern man created the internet and sent people to space
the future man... well... its up to your imagination :P
