Truth Assessment

When the truth matters and you need more than a gut feeling, structured behavioral assessment provides a documented, methodical approach to evaluating statement consistency and credibility.

KB Tenacious offers an integrated truth assessment service grounded in trained behavioral observation, cognitive interview technique, and technology-assisted analysis, not entertainment-grade lie detection. 

What This Service Does

 

We conduct comprehensive credibility assessments combining trained behavioral analysis, technology-assisted physiological observation, and, when warranted, coordinated polygraph examination, to produce a single consolidated findings report.
 

Behavioral & Technology-Assisted Assessment:

  • Structured cognitive pre-interview and statement collection

  • Behavioral observation during interview - micro-expression and macro body language analysis

  • Computer-aided facial action and expression analysis running simultaneously with interview

  • Contactless physiological observation as an independent corroborating data layer

  • Paralinguistic cue observation - voice pattern, rate, and speech error analysis

  • Cognitive load and response latency indicators

  • Statement analysis - word choice, tense shifts, omissions, and qualifiers

  • Inconsistency tracking and narrative consistency analysis

  • Structured interview and negotiation technique

  • Written findings report with documented observations across all channels
     

Polygraph Examination (available through coordinated partnership):

  • APA-standard polygraph examination conducted by a certified examiner

  • Examination integrated directly into our assessment process, our technology-assisted observation runs alongside the examiner's work without interference

  • We coordinate with a trusted examiner partner, or work with an examiner of the client's choosing where appropriate

  • Findings incorporated into a single consolidated report alongside our behavioral and technology-assisted observations

All truth assessment services require written consent under RCW 9.73. Accuracy is not guaranteed. Findings represent trained investigative observations - not legal conclusions. A realistic accuracy ceiling of 88–93% under good conditions is our stated standard; we will not overstate our capabilities.
