Answer 1

whoever said that(a lot do) may or may not be right...im not here for that....listen up: UNLESS SOMEONE HAS SOLID EVIDENCE TELL THEM **** YOU AND walk away

Answer 2

This is an old misunderstanding by many people in our culture.

However, it is possible that we are not using our minds to its full potential. We live day to day only drawing on ten percent of our thinking abillity. I'm sure for the most part, you do not sit around all day solving difficult Calculus problems. If you were doing that, you would probably be using 70 to 90 % of your POTENTIAL brain power.

On the other hand, every tiny piece of your brain is designated a specialized task for running your body!
each part of your cerebral cortex controls a muscle or an eye or ear etc. Under that is the limbic system which controls memory and other things. below that is the brain-stem which contols heart rate and breathing etc. YOU are currently using
ALL of your brain, it's just the "volume control" is set to play at 10% unless you are doing serious problem solving.

Answer 3

I use 27 percent of my brian. The brain-power statement is common, but that doesn't make it necessarily true. Many activities that we do don't require use of much brain-power, and others that would require brain-power are simply limited by the amount of multi-tasking you can do. If I were trying to write this and memorize the Book of Matthew at the same time, I doubt I could do that, but not so much because of lack of brain power.

Answer 4

It's not that there is 90% that *never* gets used; it's that you use less than 10% at any given time.

However, government employees often use *far* less than 10%. Note the link below, about a French tax official

Answer 5

Our advanced technology lets us scan brains and measure all activity that occurs in any part of the brain.

Answer 6

That's a myth. We use all of our brains. However, we rarely use more than a small percentage at one time. I think that might be where the myth got started.

They measure these things a lot of different ways.
