The Designer's Obligation
The structural duty — analogous to medical and structural-engineering obligations — that knowledge of mechanism imposes on those who design tools affecting millions who cannot see the mechanism themselves.
The designer's obligation is the ethical and structural duty
Raskin's framework imposes on technology designers whose work shapes the cognitive environment of millions. The obligation is grounded in the same principle that governs pharmaceutical, food-safety, and structural-engineering regulation: specialized knowledge creates an asymmetry of understanding
between the provider and the public, and the asymmetry generates obligations that the public cannot discharge through its own efforts. The patient cannot study pharmacology. The consumer cannot test nutritional content. The building occupant cannot evaluate structural integrity. The user of an AI system cannot see the engagement architecture
