Competence without Comprehension

Dennett distinguishes successful performance from comprehension of its rationale. Biological processes and engineered procedures can produce useful capabilities without human-like understanding, while understanding can itself support further capabilities.

Doing a task successfully and understanding why a method works are different accomplishments. A procedure can exploit a regularity without representing its rationale in human terms. Conversely, being able to explain a principle does not ensure reliable execution under pressure or in a new setting.

Assess both dimensions when they matter. Bounded performance may be sufficient for a narrow tool, while unfamiliar conditions may require explanation, adaptation, or a reliable handoff. The distinction prevents two errors: dismissing useful performance because its process is unfamiliar and inferring broad understanding from a few impressive outputs.

When to use it

Use when assessing unfamiliar methods, bounded automation, procedural learning, or claims that impressive outputs necessarily demonstrate broad understanding.

How it can help

Evaluate performance and explanatory or adaptive capacity separately. Decide which are required for the actual task and what oversight is appropriate.
