# Model Contestability **Domain:** AI Governance / Due Process / Administrative Systems **Doc Type:** Canonical Governance Principle **Maturity:** Developed ## Definition **Model contestability** is the practical ability of an affected person or community to discover that a model influenced an outcome, understand the relevant basis, challenge data and assumptions, introduce contrary evidence, obtain human or independent review and receive an effective remedy. Transparency alone is insufficient. A perfectly documented model remains unaccountable if no one can change its consequential output. ## Requirements - notice that an automated or model-mediated determination occurred; - provenance for the material data and classifications; - an intelligible statement of decisive factors; - domain-specific [[wiki/Score Separability|Score Separability]]; - a review authority independent of the original model operator; - timely correction and restoration of wrongly withheld benefits or rights; and - collective standing where a model harms a community rather than one isolated individual. - a [[wiki/Semantic Feedback Channel|Semantic Feedback Channel]] through which context and alternative causal models can enter the operative system; and - [[wiki/Counterfactual Opportunity|Counterfactual Opportunity]] sufficient to test whether changed conditions defeat the forecast. ## Climate and Administrative Context Climate-risk models influence insurance, credit, infrastructure, relocation and sovereign finance. [[articles/Climate Justice and Global Reparative Systems|Climate Justice and Global Reparative Systems]] treats appealability as part of the administrative stack. [[wiki/Prediction Is Not Jurisdiction|Prediction Is Not Jurisdiction]] supplies the corresponding constitutional limit. [[articles/Ambiguity Will Destroy Man and Machine|Ambiguity Will Destroy Man and Machine]] distinguishes being modeled from being heard. Contestability fails if the subject can submit words but the model continues treating behavior as the only authoritative signal. [[articles/Peak Person and the Predicaments of Prediction|Peak Person and the Predicaments of Prediction]] adds that a challenge cannot succeed if the institution has already removed every opportunity capable of falsifying its forecast. ## Key Insight **An explanation describes power; contestability gives the governed a means to resist and correct it.** ## See Also [[wiki/Appeals Mechanisms|Appeals Mechanisms]], [[wiki/Algorithmic Determinations|Algorithmic Determinations]], [[wiki/Algorithmic Constitutionalism|Algorithmic Constitutionalism]], [[wiki/Fiduciary Governance|Fiduciary Governance]], [[wiki/Construction Transparency|Construction Transparency]]
