“When you’re arrogant and egotistical,” says Dr. Olds, “you’re shutting out complexity, novelty, and unpredictability to preserve a distorted self-image. Any incoming information that could lead to self-doubt is stamped out. It’s a massive data reduction. Humility moves in the other direction, it opens us up and increases incoming information. As a result, there is more opportunity for pattern recognition, more dopamine, and less need for judgmental metacognition.”
