Why Intuition isn't always right

In 2 million years, human brain has nearly trippled in mass, gaining new structures... mainly the prefrontal cortex which most importantly acts as an experience simulator... have experiences in our head before we try them out in real life. No other animal can do this quite like we can.

Impact bias is the tendency for this simulator to work badly - things actually have far less impact, less intensity, & much less duration than we expect them to have.
