Detect deception. Evaluate authenticity. Protect the truth.
CSAA is the forensic pathway of the NOUS Cognitive Intelligence Platform. It applies Neural Oscillation Signature Theory to determine whether a narrative is authentic, constructed, or deceptive — using only the language itself.
The Cognitive Signature Authenticity Assessment (CSAA) analyzes natural language — written or spoken — to determine the cognitive authenticity of a narrative. It does not detect lies through behavioral cues or physiological responses. Instead, it reads the cognitive signature embedded in how a person constructs language.
Every authentic experience leaves a distinct cognitive fingerprint in language. Fabricated narratives, rehearsed statements, and deceptive accounts produce measurably different cognitive patterns. CSAA identifies these differences through a deterministic, reproducible analytical pipeline.
The methodology is published in peer-reviewed literature (DOI: 10.2139/ssrn.6447802) and has been validated across multiple population groups with zero overlap between authentic and constructed narratives on all discriminant dimensions.
Constructed account with no basis in genuine experience. Characterized by absent cognitive load markers, implausible detail uniformity, and missing sensory fragmentation typical of real memory.
Narrative that has been rehearsed or guided by a third party. Detected through unnatural narrative structure, vocabulary inconsistency with the speaker’s baseline, and scripted emotional cadence.
Account containing a mix of authentic and fabricated elements. The system identifies segment-level shifts in cognitive signature, pinpointing where the narrative transitions between genuine recall and construction.
Narrative exhibiting progressive exaggeration or severity inflation over multiple accounts. Detected through trajectory analysis across longitudinal samples, comparing cognitive signature stability over time.
Evaluate witness statements, suspect narratives, and victim accounts for cognitive authenticity. Provides objective, quantified evidence to supplement traditional investigative methods.
Support Daubert-admissible expert testimony with published methodology, quantified error rates, and reproducible results. Pre-trial assessment of deposition authenticity.
Detect fraudulent claims through cognitive signature analysis of claimant statements. Identify exaggeration patterns, coached narratives, and fabricated injury accounts.
Internal investigation support. Evaluate employee statements during HR investigations, compliance reviews, and workplace incident assessments.
Assess cognitive authenticity of debriefings, intelligence reports, and source statements. Complement existing counterintelligence methodologies.
Monitor cognitive patterns in offender narratives. Detect risk escalation, deception in parole assessments, and treatment compliance evaluation.
Narrative received. SHA-256 hash generated. Timestamp and source recorded.
NOUS pipeline analysis. Each stage output hashed. Full audit trail preserved.
Five-dimension assessment. Deterministic: identical input always produces identical output.
Federal forensic format. Examiner qualifications, methodology, findings, limitations.
Source data purged within 72 hours. Only hashed report retained.
CSAA is an investigative support tool. It does not determine guilt or innocence. Results are probabilistic assessments of cognitive authenticity and should be used as one component of a comprehensive investigation. Beverly Index LLC does not render legal opinions. The NOST methodology is published and peer-reviewed (SSRN DOI: 10.2139/ssrn.6447802; Frontiers in Psychology MS 1834364 under review). Formal sensitivity and specificity metrics are under development. All assessments are conducted by or under the supervision of the Principal Investigator. CSAA reports are designed to meet Daubert admissibility standards; however, admissibility determinations are made by the presiding court.
