Let just say that tony buzan is right(even if he isn't)?

Question

that we use less than 1% of our brain potential what would we be capable if we used 100%?

Answer 1

BadBeast not know.

Only using .1% of brain right now.  

Answer 2

It's an unanswerable question!

Look at neuropsychology (google it) or google 'brain scans' and go to images. You will see that we use every part of the brain.

Buzan and similar are using our brain potential to increase their wealth potential without any of the evidential.

Answer 3

At increased brain capacity we would know that our mind is not in our brain only, and it truly is unlimited. I hope it helps.
