How SI separates signal, interpretation and proof.
These definitions protect the line between what was observed, what was interpreted, what was modelled and what was validated. They make uncertainty visible instead of allowing confident language to outrun the evidence.
39. Signal
Evidence construct · SI-DEF-039It is something that may matter and deserves interpretation.
A Signal is an observed pattern, event or change that may contain decision-relevant information about risk, opportunity, behaviour or market movement.
Where it fits: Emerges from observation and must be separated from noise through interpretation and evidence confidence.
Repeated or material changes in search, technical conditions, reviews, demand, representation, competitors or journeys.
Not automatically a cause, conclusion or action priority.
Reported with source, period, scope, recurrence, magnitude, context and confidence.
May trigger monitoring, validation, materiality assessment or escalation.
40. Noise
Evidence construct · SI-DEF-040It looks like movement but may not matter.
Noise is variation, data or activity that obscures, imitates or lacks sufficient connection to a decision-relevant condition.
Where it fits: The competing condition Search Intelligence must distinguish from signal.
Random volatility, measurement error, duplication, irrelevant scope, short-lived anomalies and non-material variation.
Not merely an inconvenient result; an apparent anomaly may later prove to be a signal.
Documenting volatility, uncertainty, data quality and reasons for exclusion or continued monitoring.
Correctly identifying noise prevents wasted action and weak governance decisions.
41. Evidence
Evidence construct · SI-DEF-041It is the factual basis for what SI says and recommends.
Evidence is verifiable information used to support, challenge or limit a factual claim, interpretation, risk assessment or decision.
Where it fits: Captured through observation, interpreted by Human Intelligence and governed through the Evidence Trail.
Data, captures, logs, research, customer statements, technical outputs, reports, records and validated observations.
Not the same as interpretation, certainty or proof of causation.
Every material item retains source, date, scope, method, context, limitations and confidence.
Gives decisions an auditable trust path.
42. Interpretation
Intelligence construct · SI-DEF-042It connects facts to possible meaning and consequence.
Interpretation is the reasoned explanation of what evidence may mean within its commercial, technical, customer and organisational context.
Where it fits: The central Human Intelligence activity between observation and governance.
Contextual analysis, comparison, causal hypotheses, materiality, competing explanations and decision implications.
Not fact; must not be presented without its evidence basis and uncertainty.
Reported separately from observed facts and labelled with confidence and limitations.
Enables action while preserving evidence discipline and challenge.
43. Materiality
Governance/evidence construct · SI-DEF-043It determines whether something matters enough to require attention or action.
Materiality is the assessed significance of a search-driven condition based on its plausible consequence, scale, urgency, persistence, exposure and decision relevance.
Where it fits: Converts interpreted evidence into governance priority.
Commercial value, customer harm, trust, risk, technical severity, category position, recurrence, reversibility and strategic relevance.
Not determined by metric size alone; may differ by sector, product, journey or risk appetite.
Reported through defined criteria, assumptions, evidence confidence and rationale.
Supports prioritisation, escalation and proportionate response.
44. Evidence Confidence
Measurement construct · SI-DEF-044It shows how sure SI can be that the evidence supports the claim.
Evidence Confidence is the assessed strength, reliability, relevance and repeatability of the evidence supporting a conclusion.
Where it fits: Qualifies every material observation, inference, model and validation.
Source quality, recency, consistency, triangulation, relevance, repeatability and known limitations.
Not Customer Decision Confidence; does not state how confident the customer felt.
Reported as a defined level with rationale, not as an unexplained score.
Determines how strongly a decision may rely on the evidence and whether further validation is required.
45. Observed
Evidence-status label · SI-DEF-045We directly saw or recorded it.
Observed is the status assigned when a fact or condition was directly captured or recorded within the stated method and scope.
Where it fits: The strongest direct evidence-status category but still requires context and limitations.
Result presence, captured AI output, log event, technical error, transaction, stated response or direct interaction evidence.
Does not mean causal, complete or representative beyond the capture conditions.
Reports must state what was observed, where, when and how.
Observed facts form the base of the Evidence Trail.
46. Inferred
Evidence-status label · SI-DEF-046The evidence suggests it, but we did not directly observe the full event.
Inferred is the status assigned when a conclusion is reasonably drawn from observed evidence but was not directly captured or validated.
Where it fits: Sits between observation and modelling and requires explicit reasoning.
Likely encounters, confidence movement, causal pathways and customer transitions supported by patterns or triangulation.
Must not be presented as observed fact.
Reports show the supporting evidence, alternative explanations and confidence level.
Enables useful interpretation while protecting credibility.
47. Modelled
Evidence-status label · SI-DEF-047It is an estimate produced by a defined model.
Modelled is the status assigned when a conclusion, estimate or scenario is generated through an explicit analytical model using stated assumptions and inputs.
Where it fits: Uses evidence and assumptions to support planning or prioritisation.
Demand opportunity, avoided loss, probability, scenario, impact range and forecast.
Not observed fact or guaranteed outcome.
Reports disclose model logic, inputs, assumptions, ranges, sensitivity and limitations.
Supports decisions where direct measurement is incomplete but must not create false certainty.
48. Validated
Evidence-status label · SI-DEF-048The conclusion has been checked and supported by more than one reliable basis.
Validated is the status assigned when an observation, inference or model has been independently corroborated through additional reliable evidence, direct customer confirmation or repeatable testing.
Where it fits: Strengthens the evidential status of a prior conclusion.
Triangulated data, repeated tests, customer research, operational confirmation and outcome evidence.
Does not remove all uncertainty or prove universal causation.
Reports state the validation method and remaining limitations.
Validated findings can support stronger governance action and control design.
49. Unknown
Evidence-status label · SI-DEF-049We do not currently know.
Unknown is the status assigned when available evidence is insufficient to establish a defensible conclusion.
Where it fits: A legitimate evidence status that may trigger further observation or accepted uncertainty.
Unmeasured effects, missing data, inaccessible journeys, unresolved causal questions and unverified claims.
Must not be converted into zero, no risk or assumed safety.
Reports state what is unknown, why and what evidence would reduce uncertainty.
Naming unknowns prevents false confidence and supports responsible risk decisions.
50. Early-Warning Signal
Evidence/intelligence construct · SI-DEF-050It is evidence that something important may be developing before the final result appears.
An Early-Warning Signal is a credible, decision-relevant indication of emerging change or exposure identified before the full commercial consequence becomes visible in conventional outcome reporting.
Where it fits: A qualified signal that enters validation, materiality and governance before lagging outcomes.
Competitor movement, technical deterioration, representation change, demand shift, review pattern and category disruption.
Not a prediction or certainty that harm or opportunity will occur.
Reported with evidence confidence, lead time, plausible consequence and monitoring or response recommendation.
Enables earlier mitigation, protection or opportunity capture.
51. Contribution
Measurement construct · SI-DEF-051It helped shape the result.
Contribution is the supported role that an exposure, encounter, Search Moment, action or channel played in influencing an outcome without claiming exclusive causation.
Where it fits: Connects intermediate decision influence to Business Outcomes under uncertainty.
Multi-touch influence, trust support, validation, demand creation, journey progression and risk reduction.
Not attribution; does not claim that one factor caused the outcome alone.
Reported with evidence basis, confidence, alternative contributors and limits.
Supports value interpretation without overstating causation.
52. Attribution
Measurement construct · SI-DEF-052It decides what receives credit for the result.
Attribution is the assignment of causal credit or responsibility for an outcome to one or more contributing exposures, encounters, actions or channels according to a stated method.
Where it fits: A stronger causal claim than contribution; requires a clearly defined methodology.
Single-touch, multi-touch, experimental, econometric or validated customer evidence approaches.
Not automatically established by a conversion path, last click or correlation.
Reports disclose the attribution method, assumptions, data limitations and uncertainty.
Governance should use attribution cautiously for investment and accountability decisions.
