What have we learned so far about the human brain? It messes with memories, it jumps at shadows, it's terrified of harmless things, it screws with our diet, our sleeping, our movement, it convinces us we're brilliant when we're not, it makes up half the stuff we perceive, it gets us to do irrational things when emotional, it causes us to make friends incredibly quickly and turn on them in an instant.A worrying list. What's even more worrying, it does all of this when it's working properly.
