Designing for the Bounded Builder

Designing for the bounded builder is the practical prescription that Simon's framework generates for the AI age. The premise: AI has expanded what individual builders can generate but not what they can evaluate. The binding constraint has shifted to judgment, attention, and the integrative capacities that bounded rationality imposes strict limits on. The design response must therefore shift too — away from structures that optimize generation (the old hierarchies, the old specializations, the old productivity metrics) and toward structures that support evaluation (new decompositions, new pedagogies, new personal practices). The prescription operates at three scales: organizational (building attention architectures that protect evaluative capacity from the flood of AI-generated output), educational (teaching evaluation rather than merely generation, building pattern libraries that enable builders to assess what they have produced), and personal (establishing disciplines that impose representation investment before search, evaluation checkpoints during production, and reflective pauses that prevent the satisficing threshold from rising past the point of diminishing returns). Each scale requires its own design,
