TL;DR

Dr. Jill Bolte Taylor, a Harvard neuroscientist who survived a massive left-hemisphere stroke, argues the brain has four anatomically distinct parts (left-thinking, left-emotion, right-emotion, right-thinking) that produce four predictable personalities.

Key insights

  • The brain is divided into four anatomical parts: left thinking (logical, analytical, ego-centered, language, social norms), left emotion (past pain, trauma, cravings, addiction, emotional reactivity),
  • Most of society functions skewed to the left-thinking portion, treating everything else as unconscious, but Taylor argues these are all conscious and can be deliberately used.
  • Emotions physiologically last only 90 seconds from the moment you think a thought; staying angry longer requires rethinking the thought and re-stimulating the emotional loop.
