Abstract
Generative artificial intelligence, deepfakes, and synthetic identities are reshaping the information acquisition and verification environment in human intelligence (HUMINT). Yet important knowledge gaps remain: mature methods are often undervalued, pseudo-frontier technologies are overstated, source reliability is conflated with information credibility, and the boundaries of AI responsibility remain unclear. This study applies an evidence-native open-source synthesis framework that integrates international norms, government standards, systematic reviews, meta-analyses, empirical research, and authoritative R&D programs. Source grading, structured analysis, an eight-dimension evaluation framework, and a maturity–risk matrix are used to identify technical effectiveness, scope conditions, and governance requirements. The findings indicate that, relative to accusatorial and pressure-based strategies, rapport-based, noncoercive information-gathering interviews are positively associated with the production of verifiable information, in part because they reduce defensiveness, suggestibility, and memory contamination. AI can augment transcription, cross-language retrieval, entity resolution, identity proofing, and training; however, independent truthfulness adjudication, machine-learning lie detection, and automated emotion recognition still lack adequate external validity. The report therefore reconceptualizes HUMINT as a sociotechnical system in which professional judgment, verifiable evidence chains, and constrained AI operate together. It proposes a capability stack, deployment matrix, and quality-gate framework to support institutional training, technology procurement, audit oversight, and the protection of rights.
