If there has never been anyone recorded to have used 100% of their brain capacity, how can 10% of the brain’s capacity be quantified?

Asked by Hypocrisy_Central (26879points) September 6th, 2014

I am sure we all have heard it at one time or another, that humans only use 10% of the brain’s capability, maybe slightly higher for MENSA quality people. If you were never able to reach the end, how can you know what percent you are in? For example, if you came upon a crevasse and you could not see the bottom, and dropped your binoculars and it landed about 15 ft. down the crack, how can someone say it fell in only 8% of the crevasse so you should be able to retrieve it. In order to know what 10% of what the brain can do, you have to know what 100% of the brain can do. How do they know the 10% they say we use is really 60% of what the brain is capable from a thinking, reasoning perspective?

Just because no one has been recorded using their brain to full capacity doesn’t mean we couldn’t figure out what its full capacity is. I’ve never filled up my bathtub all the way, but I know how much water it can hold. It doesn’t matter, though, because the “10% of your brain” statistic is a myth.

It’s a guesstimation by those with big egos.

The brain contains areas of specialization that are interconnected in complex ways. Not all of them are active at any given moment. While the efficiency of the brain’s activity can be improved through new experiences and practice, I do not think that this is the same thing as increasing its capacity.

That 10% claim has no scientific basis whatsoever. It’s just something someone pulled out of their ass long ago and people keep repeating because they like to sound knowledgeable but never bother to check if what they’re repeating is bullshit.

Most people do in fact use all of their brains. PET scans and MRI have clearly shown that nearly all of the brain is being used at any given time. The “we only use 10% of our brain” urban legend has been around for a long time, but that’s all it is.

It can’t be estimated. It’s all a crapshoot.

When you see the so-called experts bandying about numbers and supposed ‘facts’ like this,then run for the hills.

I for the most part, have 100% of my body working, but it doesn’t mean I am using it in an active, conscious sense. The blood to my toes and the muscle there in are working for if a flame got too close, my toes and legs would move from it because they work, but if I am seated doing whatever, they are not actively being used. Has anyone actively, consciously used 100% of what their brain is capable of doing?
