The Caveman—or Cavewoman, if you prefer—is the most powerful part of the brain and represents the survival instinct, which is always searching for threats. (It’s also searching for food and mating opportunities, but that’s a topic for another book.) The Caveman is also the most primitive part of the brain. It’s overwhelming focus on survival is a huge deal, and those survival instincts can overpower any other thought or desire. Obviously, we have to be alive to do what we like to do, so survival always trumps anything else. Even if the Caveman incorrectly perceives a threat, its reactions can be overwhelming.
The good and the bad news is that the Caveman is very focused on negatives to protect us. It keeps us alive, but it also often reacts negatively when a positive approach would work better. More bad news: The Caveman is very rigid, reactive, irrational, and can take over in the blink of an eye. We all know someone like this—and we all have this quality inside us, too.
