Expertise Forged by Mistakes in Narrow Domains

Bohr’s aphorism overturns the tidy myth of mastery as flawless performance. An expert, he suggests, is not the person who avoids errors, but the one who has encountered, cataloged, and outgrown almost all the errors that matter within a tight scope. In this view, mistakes are not stains on competence; they are the cartography of its borders. Knowing what fails—and why—shapes intuition, enabling fast, accurate judgments when the clock is ticking. This reorientation invites a narrower, deeper gaze: to become expert, constrain the field until the set of possible missteps is learnable. [...]

Innovation as Harmony Between Order and Chaos

Building on this interplay, the scientific method exemplifies how structured exploration leads to discovery. While hypotheses and systematic experimentation represent order, unexpected results or anomalies introduce elements of chaos. For instance, famous accidental discoveries like Alexander Fleming’s penicillin arose precisely because rigid protocols allowed room for unplanned observations. Thus, science advances through a careful dance between established procedure and openness to the unpredictable. [...]
