Psychologist Anders Ericsson's research on expertise defines deliberate practice. In golf, it is a specific type of structured, focused practice with four elements. The first is a specific improvement goal for each session. The second is pushing slightly beyond your current ability. The third is immediate, meaningful feedback, and the fourth is full mental concentration throughout. It differs from "play," which is enjoying golf without an improvement focus. It also differs from "naive practice," which is repeating shots without specific goals or reflection. Ericsson argued that accumulated deliberate practice is a major driver of expert performance. How much of the difference between players it explains is still debated.

In golf, deliberate practice means every session starts with a specific technical goal. Goals like "maintain wrist hinge to hip height in the downswing" or "start each putt on the intended line" work well. A vague goal like "work on my iron swing" does not. The goal is specific enough to judge on every shot. Feedback can come from immediate observation: did I achieve the specific goal on this shot? It can also come from an outside source, such as video review, a coach, a mirror, or alignment sticks. The practice also demands full attention. Checking your phone between shots, chatting casually, or hitting balls mindlessly is not deliberate practice, however many balls you hit.

For most everyday golfers, the lesson of deliberate practice is to practice differently, not to practice more. The idea is that hours of mindless ball-hitting produce less progress than fewer hours of focused practice. Compare a golfer who hits 300 mindless range balls a week with one who hits 50 balls a week in full deliberate practice. The first golfer is unlikely to improve as fast. Full deliberate practice means specific goals, immediate feedback, full focus, and reflection at the end of each session.
