# Pre-Event Inference **Pre-event inference** reconstructs hidden present conditions and forecasts conditional trajectories before a terminal event occurs. It asks which latent states remain compatible with incomplete observations, how their relative probabilities change, and which lawful new observation would best discriminate among them. This is a synthesis concept connecting inverse problems, state estimation, data assimilation, uncertainty quantification, and value-of-information analysis to prediction-led intelligence. Technical applicability does not establish that any particular research program was operationally deployed for counterterrorism. ## Relationships - **methods:** [[wiki/Inverse Problem|Inverse Problem]], [[wiki/State Estimation|State Estimation]], [[wiki/Data Assimilation|Data Assimilation]], and [[wiki/Uncertainty Quantification|Uncertainty Quantification]]. - **collection choice:** [[wiki/Value of Information|Value of Information]] and [[wiki/Collection Management|Collection Management]]. - **operational domain:** [[wiki/Predictive Policing|Predictive Policing]] and [[wiki/Probabilistic Precrime|Probabilistic Precrime]]. - **technical bridge:** [[wiki/Oden as Predictive-Science Rosetta Stone|Oden as Predictive-Science Rosetta Stone]]. - **collection route:** [[wiki/Counterterrorism Collection - Predictive Policing and Probabilistic Precrime|Predictive Policing and Probabilistic Precrime]]. ## Sources / Provenance - [RAND — Predictive Policing: The Role of Crime Forecasting in Law Enforcement Operations, 2013](https://www.rand.org/content/dam/rand/pubs/research_reports/RR200/RR233/RAND_RR233.pdf) - [[research/Oden Institute - Theater-to-Person Predictive Scale|Oden Institute — Theater-to-Person Predictive Scale]] **As of:** 2026-09-23
