What the PURSUE files conclude

How many of the declassified files explain what was seen, how many leave it unresolved, and what the unresolved ones rest on. Every number counts only what the record itself states — the agency, the investigators, a witness or a document it cites — not our opinion. How this was counted. For the overall statistics, see PURSUE by the numbers.

How this was counted

Each file was read by Claude Haiku, an AI model, from our analysis of that file: its summary, key findings, stated conclusion and credibility notes. It recorded what the record itself concludes, which mundane explanations the record raises, and what the account rests on. Explanations that only our own analysis suggests are not counted.

“Explained” means the record presents a mundane cause as its assessment, even when hedged as probable. “Assessed as benign” without an identification counts as unresolved: it is a threat call, not an explanation. A record AARO filed on its “Unresolved UAP Report” form, or that says the operator was unable to positively identify the object, counts as unresolved even when it also disclaims any analytical judgment. Files that report no single incident — papers, letters, artwork and compilations of many reports — are left out of the shares.

The classification is AI-assisted and can be wrong. If a file is misread, please tell us. The verdicts are also columns in the open PURSUE dataset.
