To some degree, the critic arises out of that negativity bias in that our brains are oriented towards threat and toward survival. The critic really started as a survivor mechanism in early infancy and childhood when we were trying to navigate our early family system and culture; when we're learning how to fit in so we could optimize that flow of love and affection. It was an internal voice telling us to shut certain patterns and reactions down, that negativity bias that's always looking for what's wrong, looking for the threat.
