Primes¶
- Side Effect
- A school system optimizing a declared test-score metric hits the prime's Goodhart pattern: the declared effect (scores) improves while the shared substrate (genuine learning, teacher trust) deteriorates — teaching-to-the-test — and the corrective the prime prescribes is to instrument the substrate (broader assessments) rather than the declared metric alone.
This sourceStatement of Campbell's Law — that a quantitative indicator used for decision-making becomes corrupted and distorts the social process it monitors, as in teaching-to-the-test.

Mechanisms¶
- Acceptance Criteria
- Its failure mode is that a deliverable can pass every criterion and still be bad, because the criteria measure the measurable and quietly stand in for the quality you actually cared about
This sourceWarns that decision-linked quantitative indicators face corruption pressure and can distort the processes they are intended to monitor.

- Performance-Linked Renewal
- Its central failure mode is measure fixation: once survival hinges on a metric, effort migrates to the metric rather than the mission — teaching to the test, and cream-skimming the easy cases to hit targets while the hardest-to-serve are quietly dropped.
This sourceShows how decision-linked performance indicators redirect effort: teaching to test items, concentrating on easy cases, and neglecting those most in need.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 4 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
