Slade Wilson has as one of his superpowers “the ability to use more of his brainpower than the average person.” This is kind of a useless power though. It is a common misconception among people to think that humans use only 40% of our brain power. This is true but only if you understand the context of the statement. The human brain has evolved over our history to be quite an efficient organ. In fact we have sufficiently smaller brains than cro-magnons but ours are more efficient making us more intelligent. What we wouldn’t have evolved to do is to have an organ which is 60% useless. Imagine that your heart can pump 150% percent more blood, but just doesn’t. The extra muscle that our body would have to produce would be wasted for an organ that wasn’t justifying so much input. This holds true with the brain as well. So when they say that humans use only 40% of our brainpower its not really accurate. The average human in the span of a regular day will use about 99.9% of their brainpower, just if you used more than 40% at a time your brain would get fried and you would probably be clueless as to what to do. Perhaps some people are better at using their brain power in different ways – in fact some say that the differing viewpoints that people can bring to a conversation are quite valuable if they use different parts of their minds. For instance there are some novel solutions to problems if you are using the creative part of your mind and not just the analytical. Still even then you wouldn’t be using anything close to 100% of brain power because you couldn’t . Brain power includes every single part of our brain from the most refined parts down to the more basic amygdala. So to describe this another way, imagine playing a complicated piano arrangment while screaming at the the music because you find it terrifying. Its not much of a power.
