Judit became the strongest female chess player in history. At 15 years and 4 months, she broke Bobby Fischer’s record to become the youngest grandmaster ever at the time.

The outcome is unambiguous. The lesson most people drew from it is wrong — not because the experiment failed, but because it succeeded in a very specific kind of environment. That specificity is largely invisible to the measurement systems we use to evaluate expertise. What “Wicked” Actually Means Chess is what researchers call a “kind” learning environment. The rules don’t change. Feedback is immediate. Patterns recur reliably enough that ten…
