Donald Schön
1930–1997
Schön studied how professionals actually think in practice — not by applying theory, but through “reflection-in-action,” adjusting in real time to unique situations that textbooks never anticipated.
The Reflective Practitioner
The Reflective Practitioner (1983) examined architects, psychotherapists, engineers, and managers at work. He found that competent practitioners don’t solve problems by applying rules. They have a “conversation with the situation” — trying something, reading the response, adjusting, trying again.
This is fundamentally different from the “technical rationality” model that dominates professional education: define the problem → select the theory → apply the solution. In practice, the problem isn’t given — it has to be framed. The theory doesn’t apply cleanly. The situation talks back.
Reflection-in-Action
Schön distinguishes between reflection-on-action (thinking about what you did afterward) and reflection-in-action (thinking about what you’re doing while you’re doing it). The latter is the mark of expertise: the ability to be both actor and observer, adjusting in real time.
This is what session logs and break reviews attempt to capture: not just what happened, but the quality of attention while it was happening. The trusted system’s review flow is Schön’s reflection-in-action, formalized.

“The practitioner allows himself to experience surprise, puzzlement, or confusion in a situation which he finds uncertain or unique.”
