In 1980 the brothers Stuart and Hubert Dreyfus, working at the Operations Research Center at the University of California, Berkeley, produced an 18-page report for the United States Air Force Office of Scientific Research. The Air Force wanted to know how a pilot goes from following a flight manual in a simulator to flying a jet in a dogfight without consulting mental checklists. The brothers later expanded the work into the book Mind Over Machine. Their model traces a learner from the novice, who follows context-free rules like holding exactly 35 miles per hour, through the advanced beginner who uses experience-based maxims, to the competent performer who chooses a plan and feels real emotional stakes in success and failure.

Beyond competence, intuition takes over. The proficient performer sees what a situation calls for but still decides analytically what to do, while the expert fuses perception and action through what the brothers called direct holistic discrimination. A sixth stage, mastery, was added later for people who accept short-term drops in performance to expand their field. Researchers Fernand Gobet and Philippe Chassy challenged the model, pointing to chess grandmasters who calculate moves far ahead. Stuart Dreyfus answered with the idea of deliberative rationality and argued in a 1982 article that chess is a closed system and a poor guide to messy real-world skill.

• Novices keep following a rule even when context changes, such as driving 35 miles per hour past a crowded school at recess.
• The model holds that competent learners often stall because falling back on the checklist shields them from the sting of personal failure.
• A proficient nurse can sense a patient deteriorating from skin color and breathing before checking the monitor, but still deliberates over the response.
• Examples of mastery include Paul Cézanne reworking visual form, Stephen Curry centering the three-point shot and B.B. King using the electric guitar's sustain.
• The episode closes with the model's claim that a computer stays an eternal novice, stuck applying context-free rules.
