Study models of excellent performance to build a representation of the target

Absorb what elite performance looks like in concrete detail before trying to produce it.

Why it works

A mental representation is only as good as the model it is built from. Detailed study of excellent performance — not just exposure to good enough — provides the high-resolution target that the learner’s attempts can then be compared against. The gap between the observed model and the learner’s own performance is the feedback source that drives each iteration of practice.

How to do it

1. Identify multiple concrete examples of excellent performance in your target domain.
2. Study them closely enough to be able to predict what comes next — not just recognize it when it appears.
3. Articulate specifically what distinguishes the excellent from the merely good.

Evidence

Expert memory for domain-relevant patterns (expert chunking) is one of the most replicated findings in expertise research, originating with Chase and Simon’s chess studies. The role of studied models in building these patterns is consistent with deliberate practice theory. (observational)

These are observational studies comparing experts and novices; the causal direction — that studying models builds expert representations — is supported mechanistically but harder to isolate experimentally.

Common mistake

Studying mediocre or "good enough" examples because excellent models are harder to access, building a representation calibrated too low to drive high-level performance.
