" Judgments based on intuition seem mysterious because intuition doesn’t involve explicit knowledge. It doesn’t involve declarative knowledge about facts. Therefore, we can’t explicitly trace the origins of our intuitive judgments. They come from other parts of our knowing. They come from our tacit knowledge and so they feel magical. Intuition sometimes feels like we have ESP, but it isn’t magical—it’s really a consequence of the experience we’ve built up. "
