Research Platform

Credibility Systems

Structured therapeutic and research tools for disclosure review, preparation, and ethical assessment support.

Credibility Systems hosts reflective, educational, and pilot-stage tools for organising assessment-relevant information. The platform supports structured disclosure preparation, therapeutic question development, relationship-trust reflection, and research into decision-support methods. These tools do not provide determinations of fact, clinical diagnoses, legal conclusions, or substitutes for professional care.

Pilot tools available on the platform

These tools are designed for reflection, preparation, and structured discussion. They are not truth tests, diagnoses, legal evidence, or substitutes for professional support.

Therapeutic Disclosure Preparation

What Credibility Systems supports

The platform hosts structured tools and pilot-study materials for therapeutic preparation, disclosure review, and assessment-support research.

Pilot Questionnaires

Structured questionnaires designed for pilot testing in credibility research contexts.

Behavioural Indicator Frameworks

Frameworks for organising and evaluating behavioural indicators relevant to credibility assessment.

Bayesian Probability Models

Tools for exploring how prior probabilities, base rates, and test accuracy interact in decision-making.

Base-Rate & Predictive-Value Tools

Calculators and reference materials for understanding positive and negative predictive values.

Risk-Banded Reporting Research

Research into how risk bands can structure reporting and communicate assessment outcomes.

Participant Information & Consent

Materials to support informed consent and ethical participation in pilot studies.

Areas of investigation

Current and planned research themes across the platform.

Bayesian Decision-Support Models

Exploring how Bayesian reasoning can improve structured credibility decisions by integrating prior probabilities with observed data.

Behavioural Questionnaires

Developing and piloting structured questionnaires for research into behavioural indicators relevant to credibility assessment.

Risk-Banded Reporting

Investigating how risk categories and banded reporting can structure the communication of assessment outcomes.

Polygraph Screening Methodology

Research into the evidence base, methodology, and limitations of polygraph screening within structured credibility frameworks.

Base Rates & Predictive Values

Examining how base rates of deception, sensitivity, and specificity affect the predictive value of credibility assessment tools.

Disclosure Preparation Frameworks

Developing frameworks that support structured review of disclosure clarity, completeness, timeline anchoring, and focused polygraph question development.

Ethical Notice

Tools and questionnaires on this site are reflective, educational, or research-oriented measures designed to identify patterns of concern, uncertainty, and perceived trust strain. They are not forensic, clinical, or evidential reports, they do not provide determinations of fact, and they must not be used to pressure, monitor, challenge, test, punish, or coerce another person.

Research Platform & Professional Practice

Credibility Systems is the research and pilot-development platform associated with the Centre for Forensic Neuroscience.

The platform develops structured tools for research, reflection, assessment preparation and professional decision-support. It does not provide forensic findings or determine truth, deception, guilt or liability.

Operational forensic assessment, professional polygraph examination, investigative consultation and case-specific reporting are provided separately by the Centre for Forensic Neuroscience.
