definition: On the ward, trustworthiness is something a clinician grants an AI aid case by case: an output is trustworthy when it can be checked against the patient in front of them, its known failure modes, and its stated confidence, and when overriding it carries no procedural penalty. Clinicians operationalize this as calibrated reliance — following the tool where evidence shows it outperforms unaided judgment, and distrusting it for presentations outside its validated population. A tool that cannot be safely doubted is, in this register, not trustworthy however strong its aggregate accuracy.
do statement: Check an AI recommendation against the individual patient and the tool's validated scope, rely on it where warranted, and override and report it where not.
example: E.g., an ICU nurse treats a sepsis alert as trustworthy for medical admissions but escalates rather than relies on it for post-surgical patients outside its validation cohort.
dispute status: contested
dispute note: Clinical human-factors specialists count warranted distrust and override as part of trustworthy use, while deployment leads often read low acceptance rates as a trust failure to be engineered away.

definition: For patients, trustworthiness attaches to people and institutions before it attaches to systems: an algorithm is trustworthy to the extent the clinician using it is honest about its role, consent is real, and the hospital has a track record of acting in patients' interests — especially for communities with histories of medical mistreatment. No certificate substitutes for this relational warrant; a technically assured system deployed without candor can still be untrustworthy in the only sense that matters to the person in the bed.
do statement: Ask whether and how an AI system is involved in your care, what it is for, and who answers when it errs, before accepting its role in decisions about you.
example: Distrust rooted in cases like the US care-management algorithm that understated Black patients' needs (Obermeyer et al. 2019) shapes whether patient communities accept new clinical AI at all.

definition: For hospital executives authorizing clinical AI, trustworthiness is an evidentiary and liability judgment made at procurement: a system is trustworthy when it holds the required regulatory status (CE marking under the MDR, FDA clearance), its clinical validation covers the intended population, indemnity and vendor support are contracted, and its use fits credentialing and insurance conditions. The deployment decision converts this dossier into institutional risk acceptance; once the evidence gates are passed, the organization treats the system as trustworthy for its authorized indication and directs staff to use it accordingly.
do statement: Evaluate the regulatory, clinical-validation, and liability evidence for an AI system, and decide whether to accept deployment risk for a defined clinical indication.
example: A board approves an FDA-cleared diabetic-retinopathy screening system (e.g., IDx-DR, cleared 2018) for primary-care use on the strength of its pivotal-trial evidence and cleared indication.
dispute status: documented_dissensus
dispute note: Anchors one side of a documented dissensus: whether ex-ante clearance and trial evidence suffice to warrant trust at a specific deployment site, against the local-monitoring position held by governance stewards.

definition: For clinical-AI engineering teams, trustworthiness is a decomposable, measurable bundle: a system is trustworthy insofar as each NIST-named characteristic — valid and reliable, safe, secure and resilient, accountable and transparent, explainable and interpretable, privacy-enhanced, and fair with harmful bias managed — is specified as a requirement, measured against targets on representative data, and evidenced in documentation that survives independent review. The framing is explicitly verificationist: meeting stakeholders' expectations in a verifiable way. A claim without a metric, a test set, and an acceptance threshold is not an engineering claim; trustworthiness is built and demonstrated, not conferred by reputation.
do statement: Translate each trustworthiness characteristic into measurable requirements with test evidence and acceptance thresholds, and document results for independent verification.
example: E.g., a sepsis-model team ships a release only when AUROC, calibration drift, subgroup performance deltas, and failover behavior all meet pre-registered thresholds on a held-out multi-site dataset.

definition: Clinical-AI development shops following the EU ethics line operationalize trustworthiness as conformity with the HLEG's three-part test — lawful, ethical, robust — cashed out through seven requirements: human agency and oversight; technical robustness and safety; privacy and data governance; transparency; diversity, non-discrimination and fairness; societal and environmental well-being; and accountability. In practice this is a design-gate checklist: each requirement gets an owner, design evidence, and a trade-off log, using the guidelines' assessment list adapted to the clinical workflow. Trustworthiness here is an obligation architecture the builder must satisfy, not a performance number.
do statement: Map each HLEG requirement to an owned design deliverable with evidence and a recorded trade-off rationale, gating release on completion of the assessment list.
example: E.g., a radiology-AI team's release gate includes a completed HLEG-derived assessment list, with the transparency requirement discharged through clinician-facing model documentation.
dispute status: contested
dispute note: Teams split on whether HLEG conformance is a distinct engineering deliverable or duplicative of MDR quality-management obligations; the assessment list's voluntary status keeps this variance live.

lens facet: infrastructural
definition: In clinical-AI governance and audit practice, trustworthiness is a maintained state, not a granted status: it exists only while the surveillance infrastructure that would detect its loss is running. Stewards operationalize it as a live evidence chain — model inventory entry, deployment-site validation, performance and drift dashboards, incident and override logs, and a defined suspension trigger — reviewed on a schedule. Regulatory clearance is an entry condition; a cleared system with no local monitoring is treated as unmanaged risk, because trustworthiness claims decay silently as populations, practice patterns, and upstream data change.
do statement: Certify a clinical AI system only against a running local-monitoring regime; verify drift, override, and incident evidence on schedule and trigger suspension when thresholds fail.
example: External validation of a widely deployed proprietary sepsis model found far weaker performance at the study site than vendor-reported figures (Wong et al. 2021), the archetypal case for site-level evidence.

definition: For the credit analyst or trader using model outputs, a model is trustworthy when the model-risk apparatus says so and says so currently: it appears in the model inventory with a valid independent validation, it is being used within its approved purpose and population, known limitations and compensating controls are stated, and ongoing monitoring has not breached thresholds. Front-line users are not expected to re-derive the mathematics; they are expected to know the approval status and scope of every model they rely on, and to escalate use outside scope rather than improvise around it.
do statement: Confirm a model's validation status, approved scope, and stated limitations before relying on its output, and escalate any proposed use beyond that scope.
example: E.g., an underwriter declines to apply a retail default-probability model to a new buy-now-pay-later portfolio because the approved-use statement covers only classic instalment credit.

definition: For bank boards and senior management under supervisory model-risk guidance, trustworthiness is never a property of a model alone but of the control framework around it: models are presumed wrong in some respects, so warranted reliance is created by effective challenge — independent validation, ongoing monitoring, inventory completeness, and clear ownership — sized to each model's materiality. A decision-maker demonstrates trustworthy use to a supervisor by evidencing this framework, not by vouching for any model; accepting a model's output means accepting a documented residual model risk within the institution's stated appetite.
do statement: Set model-risk appetite, fund independent validation proportionate to materiality, and accept or restrict each model's use based on evidenced residual risk.
example: E.g., a risk committee approves an IFRS 9 provisioning model for reporting but caps its use in stress projections until validation resolves flagged instability in downturn scenarios.

definition: For model developers in a bank, trustworthiness is demonstrated reproducibility under challenge: development must produce not just a performing model but an evidence pack — data lineage, assumptions and limitations, benchmark comparisons, sensitivity and stability analyses, outcomes tests — sufficient for an independent validator to reproduce and attack the work. A model whose results cannot be regenerated from documented inputs, or whose behavior under stressed conditions is uncharacterized, is untrustworthy regardless of backtest performance, because supervisory practice treats undocumented soundness as unsound.
do statement: Build models with documented lineage, assumptions, and testing sufficient for an independent party to reproduce the results and probe behavior under stressed conditions.
example: E.g., a developer's credit-scoring handover includes seeds, frozen datasets, and sensitivity runs so validation can reproduce the reported discrimination metrics exactly before challenge testing begins.

definition: For model validation and internal audit functions, trustworthiness is the auditable output of effective challenge: a model earns and keeps trusted status through independent validation evidencing conceptual soundness, ongoing monitoring, and outcomes analysis, recorded in the inventory with findings, limitations, and remediation deadlines. Trust talk without artifacts is itself a finding; the function's stance is institutionalized skepticism, in which every model is challengeable and trust is exactly as durable as its most recent evidence. Trustworthiness is thereby fully proceduralized: what passes the challenge regime is trustworthy, what bypasses it is not.
do statement: Assess models through documented independent challenge, record findings and use restrictions in the inventory, and withdraw trusted status when revalidation or monitoring lapses.
example: E.g., internal audit downgrades a pricing model to restricted use because its annual revalidation lapsed, regardless of its live performance record.

definition: In newsroom practice, an AI output is trustworthy only after it has survived the same verification as a stringer's tip: every checkable fact traced to an original source, quotes confirmed to exist, statistics reproduced from primary data. Because generative tools fabricate fluently, reporters operationalize trustworthiness negatively — the model is a drafting aid whose claims are presumed unverified, and trust attaches to the verification trail, not the tool. An output no one can source-check by deadline is unusable however plausible it reads; publishing it converts the tool's failure into the desk's.
do statement: Treat generative-AI claims as unverified leads; trace facts, quotes, and figures to original sources before publication, and flag anything that cannot be checked.

definition: For audiences, trustworthiness is a scarce collective resource that synthetic media depletes: readers and viewers operationalize it through provenance heuristics — the outlet's name, disclosure labels, whether an image carries credentials — because unaided perception can no longer distinguish authentic from generated content. The stakes are systemic: each undisclosed deep fake taxes the credibility of everything genuine, and the liar's dividend lets bad actors dismiss real evidence as fake. Audience trustworthiness judgments are thus less about any single artifact than about which institutions still warrant default belief.
do statement: Judge AI-era content by its provenance signals and the disclosing institution's record rather than surface realism, and withhold belief from unprovenanced media.
example: Fabricated images of an explosion near the Pentagon briefly moved US markets in May 2023 after circulating from verified-looking accounts, showing how thin surface-credibility heuristics have become.
dispute status: contested

definition: For editors-in-chief and creative directors, trustworthiness is the masthead's accumulated credibility with its audience, and every AI deployment is priced against it: the question is not whether a tool performs but whether its use, if fully known to readers, would spend or grow that credibility. Operationally this means disclosure policies set ahead of need, bylines that never launder machine authorship, and willingness to forgo efficiency where discovery would read as deception. Trust here is relational and revocable — earned over years of visibly honest practice and lost in one exposed shortcut.
do statement: Decide where AI may touch the product, set disclosure and byline policy before deployment, and weigh every efficiency gain against its audience-credibility cost.
example: Sports Illustrated's publisher faced a 2023 credibility crisis when product reviews appeared under fabricated AI-generated author personas, triggering public backlash and content removal.

definition: For tool and pipeline builders in media production, trustworthiness is carried by provenance infrastructure: systems are trustworthy when they emit and preserve verifiable signals — cryptographically signed content credentials, edit histories, machine-readable markings of synthetic media — that downstream platforms and audiences can check. The builder's obligations are interoperability and tamper-evidence: marks must survive transcoding and normal editing workflows, and their absence must be detectable. The EU AI Act's marking duties for synthetic content turn this plumbing from good practice into a compliance surface, making provenance emission part of the product definition.

definition: For standards editors, ombudspeople, and rights stewards in media organizations, trustworthiness is compliance made inspectable: AI-content disclosure duties honored, labeling consistent with policy, and licensing and attribution chains for training data and generated assets documented so a rights claim can be answered. The operational test is reconstructive — for any published piece, can they establish after the fact what was generated, under what license, disclosed how, and approved by whom? Where the chain breaks, the item is treated as unpublishable or retractable, because an unanswerable provenance question is itself the trust breach.
do statement: Audit published work for disclosure compliance and reconstructable rights chains, and require retraction or relabeling where AI involvement cannot be documented.

definition: For teams building government digital services, trustworthiness must be engineered into the administrative plumbing: every automated determination logged with the input data, rule or model version, and responsible unit that produced it; citizen-facing reasons generated as a design requirement; manual-processing fallbacks and appeal hooks built as first-class paths rather than exceptions. The builder's test is reconstructability — years later, under a freedom-of-information request or judicial review, the service must show exactly why a given citizen got a given outcome.

definition: For supreme audit institutions, inspectorates, and data-protection authorities, a public-sector AI system is trustworthy only insofar as answerability is demonstrable: a legal basis identified for each processing step, decision logic documented deeply enough for a court to test it against administrative-law standards of reasoned decision-making, and responsibility traceable to an accountable official rather than dissolving into the system. The operational instrument is adversarial reconstruction: if the state cannot explain and lawfully justify an individual outcome when challenged, the system is untrustworthy as a matter of law, whatever its aggregate performance.

definition: In official statistics, trustworthiness is institutionalized through the European Statistics Code of Practice: statistics are trustworthy because the producing authority demonstrably observes professional independence, impartiality, sound methodology, and commitment to quality, verified through peer reviews and published quality reports rather than user-by-user judgment. Stewardship means protecting the production system from political interference and documenting compliance, on the premise that trust in the numbers is derivative of trust in the institution and its audited practice. A correct figure produced outside this regime carries less warrant than the regime itself confers.

op-trustworthiness-financial services-decision maker-002
type: Operationalization
of term: trustworthiness
in sector: financial services
lens facet: critical_societal
definition: For retail-bank and insurer executives, a model's trustworthiness is finally adjudicated outside the institution: a credit or pricing model that has cleared every validation gate can still be publicly untrustworthy if its outcomes strike customers, journalists, and legislators as arbitrary or discriminatory and the firm cannot explain individual decisions in plain language. These decision-makers price reputational and conduct risk alongside model risk: what do the model's decisions look like when screenshotted, can front-line staff give an account a regulator would accept, would an adverse story trigger supervisory scrutiny. A model the institution cannot defend in public is treated as untrustworthy however sound its statistics.
do statement: Weigh a model's public defensibility — explainable individual decisions, conduct-risk exposure, likely regulatory and media reaction — before authorizing customer-facing deployment.
example: After viral complaints of gender-disparate credit limits on the Apple Card in 2019, New York's DFS investigated the issuing bank; its 2021 report found no fair-lending violation, yet the episode became a board-level lesson in public trust.
dispute status: documented_dissensus
dispute note: Anchors the relational position within finance itself: reputational decision-makers hold that validated status does not settle trustworthiness, in documented dissensus with the proceduralized assurance stance of validation and audit functions.

op-trustworthiness-agriculture environment-001
type: Operationalization
of term: trustworthiness
in sector: agriculture environment
lens facet: critical_societal
definition: Among farmers and rural communities, trustworthiness of data and AI systems is earned locally and relationally: does the tool demonstrably work on this soil and in this season, do the data terms let the farmer keep control of what the machine collects, and can a satellite-based decision be contested by someone standing in the field? Certification claims and headline accuracy figures carry little weight against one season of visible failure or one perceived data grab; trustworthiness is operationalized as local validity plus fair data terms plus contestability.
do statement: Demonstrate performance under local conditions, disclose who receives the farmer's data on what terms, and provide contestation routes before asking farmers to rely on the system.
example: The 2018 EU Code of Conduct on agricultural data sharing by contractual agreement, signed by farm and machinery associations, responded to farmers' distrust of agtech by codifying the farmer's role as grantor of rights over farm-generated data.

op-trustworthiness-defense security-001
type: Operationalization
of term: trustworthiness
in sector: defense security
lens facet: contextual_domain
definition: Intelligence practice treats trustworthiness as a graded, evidence-based judgment, never a binary: human sources carry reliability grades built from track record and access; analytic conclusions carry confidence levels, high, moderate, or low, that must be stated with the judgment; and AI-enabled tools are entering the same grammar, trusted for a bounded function, at a stated confidence, on the basis of test evidence and accreditation, with the grade revisited as performance data accrues. To call anything trustworthy without stating for what, on what evidence, and at what confidence is, in this register, a tradecraft error.
do statement: Grade trust explicitly: state what a source, system, or judgment is trusted for, the supporting evidence, and the confidence level, and revise the grade as evidence changes.
example: E.g., an assessment reads 'we judge with moderate confidence' while the AI translation aid feeding it is accredited only for triage, not for evidentiary quotation: two different trust grades inside one workflow.
dispute status: contested
dispute note: How machine tools should be graded is contested: analytic-tradecraft cells extend source-reliability and confidence conventions to AI aids, while test-and-accreditation authorities insist trust attaches to systems only through formal certification of a bounded envelope, not report-style grading.

op-trustworthiness-education-001
type: Operationalization
of term: trustworthiness
in sector: education
lens facet: infrastructural
definition: For schools and education ministries procuring digital tools, trustworthiness is not a feeling but a checklist that must survive procurement: evidence of pedagogical efficacy, data-protection compliance, security certification, accessibility conformance, and vendor stability, assembled before a tool reaches a classroom. It is operationalized through procurement frameworks, edtech quality marks, approved-supplier lists, and pilot evaluations with defined exit criteria — institutional plumbing that substitutes for the individual teacher's inability to audit a vendor. A tool counts as trustworthy when the assurance chain holds: someone accountable has verified each claim, and the verification is documented and current.
do statement: Procure learning technology through documented assurance criteria — efficacy evidence, data protection, security, accessibility — and re-verify claims at renewal rather than relying on vendor assertions or teacher enthusiasm.
example: e.g., a ministry's approved-edtech list that requires vendors to evidence GDPR compliance, an independent security audit, and at least one controlled efficacy study before schools may purchase with public funds.

op-trustworthiness-engineering manufacturing-001
type: Operationalization
of term: trustworthiness
in sector: engineering manufacturing
lens facet: infrastructural
definition: Machinery earns trust through institutions, not impressions: harmonized standards, type examination by notified bodies, calibration certificates traceable to national institutes, and proven-in-use records accumulated over millions of cycles. Trustworthiness of an AI component is operationalized the same way — as verifiable conformity plus documented track record — and the friction is that learned components fit the machinery badly: they change with retraining, their failure modes resist enumeration, and the field data that would ground a proven-in-use argument restarts with every model update. Until standards settle, plants improvise assurance cases from testing envelopes, monitoring, and constrained update policies.
do statement: Build an assurance case for each AI component combining conformity evidence, tested operating envelope, field monitoring, and a controlled update policy, and state which evidence a retrain invalidates.
example: e.g., a vision safety sensor logs two million incident-free cycles, but the notified body treats the next retrained model as a new device — the accumulated trust record does not transfer.
dispute status: contested
dispute note: Some engineers accept statistical proven-in-use evidence — cycles run without dangerous failure — as the basis for trusting AI components; certification-minded engineers and notified bodies demand process-based conformity evidence, arguing retraining invalidates accumulated field history. What varies is the admissible evidence base.

op-trustworthiness-legal services-001
type: Operationalization
of term: trustworthiness
in sector: legal services
lens facet: infrastructural
definition: In legal-services procurement and practice management, trustworthiness is established through assurance infrastructure rather than declared: vendor due-diligence questionnaires, security certifications, contractual warranties and indemnities, professional-indemnity cover for AI-assisted work, and bar technology guidance. A tool is treated as trustworthy for a task when the firm can show it performed the diligence a reasonable practitioner would perform — the operative question is not whether the system is trustworthy in the abstract but whether documented reliance on it was reasonable, because that record is what the malpractice insurer, the client, and the regulator will each examine after a failure.
do statement: Build and maintain a diligence file for every AI tool used on client matters — certifications, contract terms, testing results, approved-use policies — sufficient to show reliance on it was reasonable.
example: e.g., before approving a drafting assistant for client work, a firm's general counsel requires the vendor's security certification, a no-training-on-client-data clause, and a pilot evaluation, and records all three in the approval file.

op-trustworthiness-logistics transport-001
type: Operationalization
of term: trustworthiness
in sector: logistics transport
lens facet: contextual_domain
definition: For dispatchers and customer teams, trustworthiness is earned reliance on the tracking and prediction layer: an ETA is trustworthy when its track record on that lane justifies promising it to a customer, and a tracking status is trustworthy when the scan discipline behind it is known to be tight. Crews calibrate this constantly, trusting motorway ETAs, distrusting the last mile, and adding informal buffers where the system has burned them. Verifiable track record per lane and data source, not vendor claims, is what moves an output from indication to commitment.
do statement: Track prediction hit-rates and status reliability per lane and data source, promise customers only what the record supports, and withdraw reliance where system performance has degraded.
example: e.g., a dispatch team that quotes system ETAs unchanged for line-haul but adds a thirty-minute buffer on rural last-mile routes where the model's hit-rate is known to be poor.

op-trustworthiness-personal services-001
type: Operationalization
of term: trustworthiness
in sector: personal services
lens facet: contextual_domain
definition: In a reputation economy, trustworthiness is engineered as much as earned: verified-identity badges, host status tiers, hygiene certificates on the door, response-rate statistics, and review counts are the machinery by which platforms let strangers rely on each other. For this sector a system is trustworthy when its signals track reality — when the 4.8-star cleaner really is careful, when verified means checked, and when the platform's own conduct in ranking, fees, and redress earns the reliance it invites from guests, hosts, and workers alike.
do statement: Evaluate whether trust signals — badges, ratings, verification marks — are backed by real checks, and maintain the redress and review-integrity processes that keep reliance on them warranted.
example: Airbnb's Superhost badge conditions a trust mark on measurable conduct — rating threshold, response rate, low cancellations — turning trustworthiness into an operationalized, revocable status guests can rely on.

op-trustworthiness-retail marketing-001
type: Operationalization
of term: trustworthiness
in sector: retail marketing
lens facet: critical_societal
definition: In consumer-facing commerce, trustworthiness is the accumulated warrant customers have for relying on a retailer's data-driven persuasion machinery — and it is an asset measured in conversion and retention. It is operationalized through authentic rather than fabricated reviews and ratings, personalization that stays on the acceptable side of the creepiness line, honest scarcity and pricing claims, and recommendation systems that do not exploit inferred vulnerability. The societal stake is asymmetry: the retailer models the customer far better than the customer can model the retailer, so perceived surveillance or manipulation converts directly into churn and regulatory attention.
do statement: Track trust-sensitive signals — review authenticity, personalization complaints, opt-out spikes — as leading indicators, and veto targeting tactics whose inferred-attribute basis customers would find surveillant if disclosed.
example: Target's pregnancy-prediction scoring became a canonical creepiness case when its mailers revealed a teenager's pregnancy to her father (reported by Duhigg, New York Times, 2012), reshaping how retailers camouflage inferred-attribute marketing.

op-trustworthiness-science research-001
type: Operationalization
of term: trustworthiness
in sector: science research
lens facet: critical_societal
definition: In the research system, trustworthiness attaches to claims and to the institutions producing them, and it is earned through mechanisms that make error findable: independent replication, peer review and post-publication critique, registered reports that fix predictions before data are seen, declared conflicts and funding, and a functioning correction record. Researchers therefore read a warranted-reliance question as a question about process, asking whether a claim was exposed to a serious chance of being found wrong and by whom, rather than about the confidence with which it is stated. Public trust is treated as a consequence of those mechanisms working visibly, not as a communication objective.
do statement: Judge a claim by the error-finding mechanisms it has actually survived rather than by its source's prestige, and expose your own work to comparable scrutiny before asserting it publicly.
example: Large-scale replication efforts, such as the Reproducibility Project in psychology (Open Science Collaboration 2015) and the Reproducibility Project: Cancer Biology, revised the credibility of whole literatures through systematic replication rather than any single paper's internal quality.

op-trustworthiness-technology data-001
type: Operationalization
of term: trustworthiness
in sector: technology data
lens facet: ethical_legal
definition: For teams shipping AI systems, trustworthiness is what the evidence file can demonstrate to a skeptical third party: evaluation-suite results, SLO and incident history, red-team findings, security posture, model documentation, and data-handling records, mapped onto the named characteristics of frameworks like the NIST AI RMF - valid and reliable, safe, secure, accountable, transparent, explainable, privacy-enhanced, fair - and onto customer security questionnaires and AI Act conformity work. It is operationalized as an assurance backlog: a characteristic you cannot yet evidence is a gap with an owner. Trust itself remains the deployer's and user's to give.
do statement: Map your evaluation, monitoring, security, and documentation evidence onto a recognized trustworthy-AI framework, identify the characteristics you cannot yet demonstrate, and treat those gaps as engineering backlog.
example: e.g., an enterprise sales cycle stalls until the vendor can evidence RMF-style characteristics - red-team results, uptime history, data-handling documentation - and the deal closes on the evidence file, not the demo.
