I was listening to NPR the other day and I heard a story on my favorite program, RadioLab. They were discussing a study that showed that your brain knows what you are going to do before you yourself consciously do.
Before you even realize you are going to eat another cookie; your brain is sending a signal to your hand to reach for it. Then, once you have decided to have that cookie, your body is already reaching for it.
It’s weird to think about that. I don’t like the idea of my brain making decisions and sending signals without me. (Not that it takes some great genius to know that I’m going to eat another cookie).
I already knew my brain was keeping secrets from me. Like the name of the person I just met 7 seconds ago. Or what I had for dinner last night.
But this feels different. Like my brain is out there doing things without my permission. Like it is some sentient being.
How does it know? I don’t know things myself for so long sometimes. I feel like my brain is sitting up there all smug. Watching me struggle to make up my mind and figure out how I feel. When it already knows what I am going to do.
