Designing for humans. Encoding for machines.

The Trust Stack is a diagnostic system that helps organizations assess whether public-facing content, communications, and experiences are clear, consistent, supported, and credible enough for people and AI systems to interpret accurately.

It identifies where credibility is strong, where it breaks down, and what to improve to strengthen discovery, engagement, and action.

From Dimensions to Observable Evidence

The Trust Stack does not treat credibility as a loose impression. Each dimension is broken into specific signals, and each signal is assessed through observable attributes that show whether credibility is present, clear, and supported.

5 Dimensions

The core areas of credibility the Trust Stack examines.

20+ Credibility Signals

The specific signs within each dimension that can strengthen or weaken confidence.

100+ Observable Attributes

The concrete features reviewed to determine whether each signal is present, clear, and supported.

Explore the five dimensions

Each dimension turns an abstract trust question into observable risks, signals, and design opportunities.

Do I know who made this and where it came from?
Clear authorship and origin make it easier to recognize what is official, accountable, and safe to engage with.
Risk if Provenance fails
    Impact when Provenance works
      What to look for
        Design & Innovation Opportunities

          One system, two outcomes

          For organizations
          For people

          Differentiation and Discovery

          Make your value easier to find, understand, and distinguish from alternatives.

          Clarity

          People can understand who is behind an experience, what is being claimed, and what matters.

          Conversion + Revenue

          Increase purchase, renewal, and referral by reducing hesitation at key decision points.

          Confidence

          People have clearer reasons to believe, compare, continue, or disengage.

          Risk Reduction

          Reduce avoidable doubt, complaints, competitive confusion, and reputational drag.

          Agency

          People are better able to verify, decide, and act without relying on unclear, unsupported, or misleading signals.

          Human & Machine Signals

          In AI-shaped environments, credibility has to be clear enough for people to evaluate and structured enough for machines to interpret.

          Trust Layer Human Signal AI System Signal
          Provenance People see clear origin, authorship, and accountability Structured metadata enables models to trace, index, and validate source identity
          Resonance Tone, context, and content align with intent and situation Clear semantics, stable entities, and intent signals allow accurate interpretation
          Coherence The story holds true over time and across channels Consistent narratives, entities, and structures enable cross-context understanding
          Transparency Intent, system behavior, and choices are evident and understandable Machine-readable disclosures, logic, and permissions make policy and control clear
          Verification Claims are supported by tangible evidence, not assumptions Authenticated sources, citations, and identity signals confirm accuracy and reduce uncertainty
          Experience Layer

          Where the Trust Stack fits.

          The Trust Stack does not replace model governance, security, legal, or regulatory review. It focuses on a different layer: whether credibility is clear and readable in the experience itself.

          A system may be technically robust, but if people cannot understand what it is doing, why it is recommending something, or whether it is safe to act on, confidence still breaks. This is the layer the Trust Stack is designed to evaluate.

          From Diagnosis to Action

          Find where credibility is already breaking down before it becomes a performance problem.

          Before launch, the Trust Stack helps teams evaluate whether credibility signals are clear, supported, and structured enough for people and AI systems to interpret. After launch, it helps identify where confidence weakens and what is contributing to hesitation, confusion, abandonment, or loss of trust.

          This page defines: Define the Trust Stack system and explain how each dimension supports trust, clarity, and business performance.

          This page is for: Product, brand, CX, governance, and innovation teams evaluating credibility across digital experiences.

          Primary business claim: The five dimensions help organizations diagnose credibility, reduce friction, and make value easier to recognize and verify.
