"You only use 10% of your brain." Heard that before? I have. Loads of times. It’s such a popular idea, it’s even in the movies. A typical plot might be: "Here, Joe Nobody. Take this pill! It will allow you to use the full 100% of your brain! Wow! Now you're psychic and can move things with your mind! Amazing!" ...or.... "That girl is a genius because she had radioactive accident which changed her DNA and now she can use more than 10% of her brain. And she's psychic and can move things with her mind!" According to pop culture, the fast track to superpowers is using the full 100% capacity of your brain. Now, I'm the first person to say that sci-fi/fantasy is awesome, but this is just nonsense! Why? Because we already use 100% of our brains. Last time I checked, I couldn’t move things with my mind. If I could, my breakfast would be cooking itself right now.
