A 2024 SCU white paper applies a nine-category behavioral coding scheme to 505 Project Blue Book and NICAP reports (1945–1975), finding frequency distributions across military and civilian incident types inconsistent with random natural occurrence.
Brief
Hancock, Porritt, Grosvenor, and Cates coded 505 UAP incident reports from Project Blue Book and NICAP archives against nine discrete behavioral categories, including interactive flight maneuvers, weapons-system interference, strategic installation intrusions, and occupant/entity encounters, spanning both military and civilian domains from 1945 to 1975. The 30-year window is coextensive with the Cold War nuclear buildup, making the installation-intrusion frequency data particularly salient. Observed category-frequency distributions are presented as incompatible with stochastic natural explanations, which would predict more uniform noise across behavioral bins. The study is framed as a replicable taxonomic baseline for future behavioral UAP research rather than a terminal explanatory claim.

Key points
- The sample comprises 505 incidents drawn from Project Blue Book and NICAP archives, spanning 1945–1975.
- Nine behavioral categories are applied uniformly across both government and civilian source archives, enabling cross-source frequency comparison.
- Coded categories include interactive flight, weapons-system interference, installation intrusions, and occupant/entity encounters, each treated as a discrete behavioral class.
- Frequency distributions across the nine categories are described as inconsistent with random natural occurrence, implying structured or goal-directed patterning.
- Weapons-system interference, including reported radar and missile anomalies, is coded as a category distinct from passive observation or misidentification events.
- The dual-source design (Blue Book + NICAP) allows detection of pattern consistency across a government archive and a civilian investigative database simultaneously.
Most interesting
- Occupant or entity encounters are assigned their own behavioral category, placing humanoid-report analysis inside a systematic frequency framework rather than relegating it to an unanalyzable fringe.
- Weapons-system interference is coded as a discrete class, separating it analytically from general electromagnetic anomaly reports and enabling targeted frequency tracking.
- The 1945–1975 window was selected to overlap with the construction and operationalization of U.S. nuclear delivery infrastructure, making the installation-intrusion frequency bin a direct proxy for strategic-site targeting behavior.
- Applying the same nine-category taxonomy to both the government's own Blue Book corpus and the independent NICAP database allows a cross-institutional consistency check on behavioral pattern frequencies.
- At 505 incidents, the sample is large enough to test for non-uniform categorical distributions using standard statistical methods, yet the white-paper format means formal significance values are not centrally reported in the editorial description.
- The SCU, a credentialed volunteer research organization, positions this as a methodological baseline study, an unusual framing that invites third-party replication of the coding scheme against the same or extended datasets.
