CONCEPT
The Evaluation Gap
Boden’s implied hierarchy of creative judgment—functional, aesthetic, and directional—and the growing distance between the machine’s generative range and the human evaluator’s capacity to assess what the machine finds.
When a machine can generate creative candidates faster and across wider conceptual terrain than any human, the critical question shifts from production to judgment: who evaluates what the machine finds, and with what depth of understanding? Boden’s taxonomy of
exploratory,
combinational, and
transformational creativity implies a matching three-level hierarchy of evaluation: the functional level (does the output work against specified criteria?), the aesthetic level (is it excellent, not merely adequate?), and the directional level (should this exist at all, and is this the right problem?). Each level requires a qualitatively different kind of understanding, and each is built through forms of personal engagement that devices are structurally designed to eliminate. The evaluation gap names the growing asymmetry: the machine’s combinational range now exceeds any individual human’s evaluative range, meaning the machine can connect domains the human cannot properly evaluate. This gap does not make the machine-human collaboration less productive; it makes the human’s evaluative depth—built through the friction of
focal practice—the most critical and
