In many personal improvement books I've read, people make a distinction between 2 parts of our brain:
- the logical brain, dealing with logic, judgement, thinking; what makes Humans different than Animals
- the lizard brain inherited from our ancestors, dealing with emotions and instincts, which takes shortcuts to react to the immediate problems, such as a saber tiger croping up to eat us.
The facts are, the lizard brain sometimes take actions/decisions without making the logical brain aware of that, which is at the origin of many brain biases.
I am wondering if there's a sound reason why Mother Nature didn't evolve us so that we would be made aware of our lizard brain decisions after the fact (i.e. a kind of summary for our logical brain). I mean, is there's something physical or an evolutionary reason that would prevent that?
