- Expertise is defined from three perspectives: absolute task performance, relative performance to others, or underlying psychology, with a focus on the latter as the natural development of human capacity.
- Experts rely on tacit knowledge, which is hard to articulate and involves intuition, pattern recognition, anomaly detection, and adaptation, rather than explicit facts or protocols.
- Pattern recognition is central to expertise, enabling experts to quickly understand situations and act, but experts also adapt to novel patterns they have never seen before.
- Gut instinct is not magic but stems from subconscious pattern matching; it should be considered as information but validated through experience and reflection.
