We don't use "10% of our cerebral capacity," whatever that means.

Rating: 1/10 (12 January 2019)

That humans use only 10% of our brains is a myth proclaimed from the stage by fortune tellers, fraudulent psychics, and mentalist entertainers.
No brain scientist has ever--or would ever--say this.
If you've ever seen a brain scan, then you know that the assertion that you use only 10% of our brain this is meaningless and backed by no evidence.
