Model Uncertainty
Uncertainty arising from the possibility that the model itself is wrong, meaning the chosen theoretical framework may deviate from reality and cannot be eliminated through parameter estimation.
Timeline (last 90 days)
In the field of AI risk, model uncertainty is far greater than parameter uncertainty, which means that even if some parameters can be estimated precisely, the overall conclusion remains highly unreliable.
The pragmatic path for policymakers is: for problems dominated by parameter uncertainty, give range estimates and annotate assumptions; for problems dominated by model uncertainty, prioritize scenario narratives and robustness analysis rather than single-point probabilities.
