NHI

Non-Human Intelligence — a term increasingly used in U.S. government UAP discourse to refer to any intelligence not of human origin, with deliberate breadth (terrestrial-but-non-human, extraterrestrial, interdimensional, etc.).

Non-Human Intelligence (NHI) is a term that emerged into U.S. government UAP discourse during the 2023–2024 congressional cycle, particularly in the context of testimony by former intelligence official David Grusch before the House Oversight Subcommittee in July 2023. The term has since been incorporated into draft legislative language including the proposed UAP Disclosure Act.

Why the term matters

NHI is deliberately broader than the older terms “extraterrestrial” or “alien.” It encompasses:

Extraterrestrial intelligence — life originating off-Earth.
Cryptoterrestrial hypotheses — intelligence native to Earth but biologically or technologically distinct from Homo sapiens.
Interdimensional or “ultraterrestrial” hypotheses — entities operating in physical dimensions inaccessible to standard observation.
Future-human hypotheses — descendants of humanity returning through some form of time-displacement.
Artificial intelligence of unknown origin.

The breadth is intentional: it allows policy and legislative work to proceed without committing to any specific theory of origin while addressing the empirical question of whether non-human-originated intelligence is interacting with human systems.

Status in the public record

As of the most recent AARO reporting cycle (Case #00471, FY2025 report), the U.S. Department of Defense has not publicly affirmed the existence of NHI in the meaningful sense. The 2024 AARO Historical Record Report Volume I explicitly concluded that no evidence has been found of a U.S. government program reverse-engineering NHI technology.

Council usage

The Council uses NHI in the same broad sense the term is used in current U.S. legislative drafting. Use of the term in a case file does not imply the Council has reached any verdict on the existence or characteristics of any non-human intelligence; it is used only to describe claims, hypotheses, or testimony that themselves invoke the concept.
