THE NEED TO 'GET TO THE TRUTH'?
The Cost of Getting the Truth Wrong
Uncertain Information
Over the past 20 years, we have observed the same challenge across industries: Legal disputes. Business deals. Workplace investigations.
Important decisions are often made using information that may be incomplete, misleading or deceptive - costing time and money.

Clarity Through Analysis
Using our FSLA™ methodology, we analyse a subject's own words to identify indicators of sensitivity, inconsistency and potential deception, helping clients make informed decisions with confidence.
Our work has supported law enforcement investigations, informed multi-million-pound decisions, assisted survivors of domestic abuse and helped resolve complex private and commercial disputes.

MEET THE FOUNDER
Chris Woodruff, the Founder of Deception Detection Lab, created the FSLA™ methodology in the UK to provide objective credibility assessments through linguistics. Over the last fifteen years, he has recognised the advantages of utilising Forensic Statement Linguistic Analysis, in particular the power of analysing ONLY the subjects' own words in getting to the truth.
Alongside training other analysts, Chris has established an international team educating global analysts through independent, evidence-based analysis.

THE FSLA™ FRAMEWORK PROCESS
FSLA™ follows a structured and methodological process.
FSLA™ was developed to provide a structured and evidence-based approach to credibility assessment, risk identification, and informed decision-making. Rather than relying on physiological measurements or mechanical testing, FSLA™ focuses exclusively on the analysis of communication. By examining a person's OWN words, we identify significant linguistic patterns, indicators, and areas requiring further consideration.
Every stage follows a consistent analytical framework, ensuring that conclusions are based on documented observations, objective reasoning, and verifiable linguistic evidence. The result is greater clarity, increased transparency, and actionable insight for legal professionals, investigators, organisations, and private clients.
OBJECTIVITY | CLARITY | INFORMED DECISIONS
