Professional Norms

In The You On AI Field Guide

In the Challenger case, the original standards — zero O-ring erosion, zero tolerance for unresolved anomalies — existed as explicit engineering specifications. Vaughan could document the gap between specification and practice because the specification was written down. In AI-augmented knowledge work, the equivalent specifications — understand what you build, verify what you deploy — exist as professional norms rather than formal requirements.

The invisibility of professional norms makes their drift particularly insidious. An organization can audit its compliance with a written policy; it cannot easily audit its compliance with an implicit expectation. When new practitioners enter the field, they absorb the practiced norms, not the specified ones, because the specified ones may never have been specified.

Diane Vaughan

The generational consequence is acute. Senior practitioners trained in the pre-AI environment internalized norms of comprehension and independent judgment as integral to competent practice. Junior practitioners trained with AI assistance from the outset may internalize narrower norms — does it work, does it pass, does it satisfy — as the standard of competence the environment rewards.

The reform of professional norms requires cultural rather than regulatory intervention. The standards cannot be restored by memo or checklist because they were never established by memo or checklist. They must be maintained through the same mechanisms that established them: training that explicitly addresses the standards, mentorship that models them, and institutional recognition that rewards their practice.

Origin

Andrew Abbott

The concept draws on the sociology of professions, particularly the work of Andrew Abbott on jurisdictional claims and Eliot Freidson on professional autonomy. Vaughan's framework extends this tradition by showing how professional norms operate as implicit standards whose drift is harder to detect and correct than the drift of formal specifications.

Key Ideas

Implicit rather than codified. Professional norms shape practice through training and culture, not through written regulation.

Identity-constitutive. Norms define what it means to be a competent practitioner in the field, not merely what behavior is expected.

Doubly invisible drift. The drift is invisible in the usual way normalized deviance is invisible, and additionally invisible because there is no document to measure against.

Generational transmission risk. New practitioners absorb practiced norms rather than specified ones, with no formal mechanism to detect the gap.

Cultural reform required. Restoration of drifted norms cannot be achieved through regulation; it requires training, mentorship, and institutional recognition.
