How Diplomacy Knows: From Evidence to Institutional Judgment

Diplomats.Digital | Research & Insights | October 2026

---

A diplomatic report can be accurate when it is written and misleading by the time it reaches the person making a decision.

A qualification may disappear in a summary. Two apparently independent sources may originate from the same account. A preliminary assessment may become an official position. New evidence may correct an earlier conclusion, while the original judgment continues to circulate through other institutions.

None of these problems began with artificial intelligence.

Diplomacy has always worked with incomplete information, competing accounts and decisions that cannot wait for certainty. What has changed is the scale and speed at which information is produced, processed and shared, and the number of systems involved along the way.

Today, diplomatic knowledge moves through embassies, headquarters, intelligence services, international organisations, private platforms and increasingly AI-assisted workflows. Each can contribute valuable insight. Each can also change how information is selected, interpreted or presented.

This raises a question that deserves greater attention in the future of foreign affairs:

How can diplomatic institutions ensure that what they know remains reliable, usable and accountable as it moves from evidence to action?

The answer begins well before the digital age.

1. A Diplomatic Function with a Long History

The need to understand conditions beyond one's own political territory is as old as organised diplomatic engagement. Different civilisations developed their own approaches to observation, reporting and the interpretation of foreign societies.

In the second century BCE, Zhang Qian's missions to Central Asia provided the Han government with firsthand information about states and territories beyond its established political reach. His reports informed subsequent diplomatic engagement and contributed to a wider circulation of knowledge along what became known as the Silk Roads, as documented by historian Shujing Wang.

The example illustrates a familiar diplomatic function: a representative travels beyond the centre of political authority, gathers knowledge unavailable through ordinary domestic channels and brings it back for strategic consideration.

Centuries later, Venice developed one of the best-documented traditions of diplomatic reporting.

From at least the thirteenth century, returning Venetian ambassadors were expected to provide relazioni describing the countries where they had served, their political institutions, rulers and relations with other powers.

The reports offered the Venetian Republic a means of preserving observations that might inform future negotiations.

There is a less obvious detail in this history.

In his study How to Read Venetian Relazioni, Filippo de Vivo shows that these reports were often first delivered orally and subsequently circulated in multiple manuscript versions. Some entered official archives; others spread beyond their intended institutional audience.

The movement from an ambassador's account to an enduring written record was therefore neither uniform nor neutral. Different versions could emerge as a report was presented, recorded, copied and circulated.

The underlying issue remains recognisable today: the information received by an institution is shaped partly by the process through which it travels.

Other diplomatic traditions developed comparable, though historically distinct, practices.

From the early eighteenth century, Ottoman ambassadors produced detailed sefâretnâme, or mission reports, describing foreign political institutions, societies and technological developments. The European University Institute's OTTOGLOB project examines these records as an important source for understanding diplomatic knowledge production beyond the European tradition.

These examples do not establish a single global origin or linear history of diplomatic reporting. They show how different political systems confronted a recurring problem: making knowledge gathered elsewhere available to decision-makers.

As foreign ministries and permanent diplomatic networks became more institutionalised, correspondence, memoranda, instructions and archives increasingly supported that function.

The Foreign Relations of the United States series, published since 1861, is one prominent example of how diplomatic documentation can preserve the relationship between information, institutional deliberation and foreign-policy decisions for later examination.

By the twentieth century, the systematic collection and analysis of external information had become an established government activity. In 1941, the United States created the Foreign Broadcast Monitoring Service to record, translate and analyse foreign broadcasts, distributing material and assessments to relevant agencies.

The function of diplomatic reporting also received explicit international legal recognition.

Article 3(1)(d) of the 1961 Vienna Convention on Diplomatic Relations identifies the lawful ascertainment of conditions and developments in the receiving state, and reporting on them to the sending government, as functions of a diplomatic mission.

The qualification by lawful means remains essential.

Technological access does not automatically establish legal authority. This distinction applies to contemporary digital monitoring, personal data, technical forensics and AI-assisted analysis just as it applies to other investigative methods.

The historical lesson is clear: gathering and interpreting information have long been part of diplomatic practice. The methods have changed considerably. The requirement to exercise judgment has remained.

2. When Evidence Reaches the Decision Table

One of the clearest historical illustrations of the distinction between evidence and judgment comes from the Cuban Missile Crisis.

On 14 October 1962, a U-2 reconnaissance flight obtained photographs showing Soviet missile installations under construction in Cuba. Analysis provided verified evidence that significantly changed the United States' understanding of the situation.

The images were consequential. They did not determine the political response.

President John F. Kennedy and his advisers still had to consider Soviet intentions, the risks of escalation, available military and diplomatic options, and the consequences of acting too quickly or too slowly.

The documentary record maintained by the U.S. Department of State's Office of the Historian reveals competing recommendations and difficult choices under uncertainty.

This case is an illustration of national security decision-making with major diplomatic consequences, rather than a demonstration of one particular diplomatic investigative method.

Its broader lesson remains valuable.

Evidence can establish what is happening. It cannot, on its own, determine what a government should do about it.

That distinction becomes more important as information passes through institutions with different responsibilities.

A technical analyst may assess whether a cyber operation occurred. A regional specialist may consider its political significance. A legal adviser may examine available authorities. A diplomat may assess the implications for bilateral relations. Political leadership ultimately decides among the authorised courses of action.

All may work from the same evidence and arrive at different recommendations.

That does not necessarily indicate poor analysis. They may be evaluating different risks, obligations and consequences.

Reliable diplomatic judgment therefore requires a clear relationship between the factual basis, the interpretation, the recommended options and the authority responsible for choosing among them.

3. What Research Tells Us About Diplomatic Knowledge

Academic research has increasingly examined diplomacy as a professional and institutional practice of producing knowledge.

In At Home with the Diplomats (2012), Iver B. Neumann draws on research into the everyday work of a European foreign ministry.

He identifies an important distinction between diplomats serving abroad, whose work involves gathering and interpreting information, and diplomats at headquarters, who spend substantial time producing the documents, speeches and policy texts through which government positions are developed and communicated.

Both are engaged in knowledge production, although their work takes different forms.

Costas M. Constantinou expands this perspective in Between Statecraft and Humanism: Diplomacy and Its Forms of Knowledge (2013).

He examines diplomatic understanding beyond information and intelligence gathering, emphasising the relationship between knowledge, reflection and advocacy.

This is particularly relevant because accurate information does not necessarily produce an adequate understanding of a political situation. Historical context, social meaning, professional relationships and competing interpretations can affect what the available facts mean for diplomatic engagement.

Merje Kuus adds another dimension in Diplomacy and Audit: Technologies of Knowledge in Europe (2016), examining how audit cultures and measurable standards influence diplomatic knowledge production.

Measurement can strengthen consistency and accountability. It can also shape what institutions choose to recognise as valuable knowledge.

Some of the most consequential aspects of diplomatic judgment — context, trust, informal influence and professional discretion — are difficult to capture through simple indicators.

More recently, Jérémie Cornut and Nicolas de Zamaróczy examined 408 diplomatic cables sent by the United States Embassy in Dar es Salaam between 2005 and 2009.

Their 2021 study demonstrates how diplomatic documents reveal professional practices, including which voices and types of knowledge receive greater attention.

The implication deserves consideration: an authentic diplomatic document can accurately reflect what an institution recorded while still providing an incomplete account of the environment it describes.

Together, these studies point towards a broader understanding of diplomatic knowledge.

Its reliability depends on source quality, analytical methods, professional expertise, institutional routines and the ability to recognise what remains uncertain or outside the institution's field of observation.

The growing role of systematic investigation

A recent contribution to this discussion is Abdulaziz Mohamed Al-Horr's Investigative Diplomacy: A New Paradigm for Modern Diplomatic Practice (2026).

The work, associated with Qatar's Diplomatic Institute, proposes integrating systematic investigation, multi-source verification, evidence-driven analysis and specialised analytical techniques into diplomatic practice.

Al-Horr develops a four-layer analytical approach covering official narratives, institutional structures, networks and systemic conditions. He also addresses ethical safeguards, organisational design, professional skills and simulation-based training.

His proposal reflects the increasing relevance of investigative disciplines to foreign affairs, particularly where diplomatic institutions must understand concealed networks, contested information or complex transnational activities.

These methods draw on established traditions in intelligence analysis, investigative journalism, scientific inquiry and diplomatic reporting.

Their integration into diplomatic practice can be valuable. Claims of a fundamental paradigm shift, however, require more than a coherent methodology. Comparative evidence of institutional application and results would be needed to establish the scale of such a transformation.

The wider significance is the renewed attention to methodological discipline: how institutions formulate hypotheses, evaluate evidence, test alternative explanations, communicate uncertainty and convert their findings into diplomatic options.

The development of investigative capability is part of a much longer evolution in how diplomacy produces knowledge.

The next question is what happens to that knowledge once it leaves the analyst's desk.

4. The Point Where Knowledge Becomes Vulnerable

Consider a foreign ministry receiving reports of an emerging international crisis.

An embassy submits a carefully qualified assessment. Headquarters prepares a shorter briefing. Another government department adds information from its own sources. A coordination team combines the material into a common situation report. Senior leadership receives recommendations for action.

Every stage serves a legitimate institutional purpose.

Yet each also involves interpretation.

The information may be accurate at the point of collection while its meaning changes through successive summaries, translations, selections and decisions.

Five distinctions help identify where this can happen.

These distinctions are supported by established analytical practice.

For example, the United States' Intelligence Community Directive 203 requires analysts to distinguish underlying information, assumptions and judgments, explain material uncertainty and communicate confidence appropriately.

The directive applies to the U.S. intelligence community. It is relevant here as a documented example of analytical discipline, rather than as a universal standard for foreign ministries.

The Berkeley Protocol on Digital Open Source Investigations provides another methodological reference, particularly for preserving and evaluating digital material in investigations of alleged violations of international criminal, human rights and humanitarian law.

Diplomatic institutions operate under different mandates, but the general questions about authenticity, integrity, context and responsible use are relevant across many analytical settings.

The institutional conversion problem

Verification addresses the quality of the evidentiary basis. Institutions also need to preserve the connection between evidence and the decisions it informs.

This is where a different category of weakness can emerge.

An original report may be sound, but its qualifications disappear in a policy summary.

A change in evidence may reach the author of an assessment but not the units that acted upon it.

An embassy and headquarters may retain different versions of an evolving situation.

A successor may inherit an established recommendation without understanding the assumptions behind it.

We can think of this as a problem of institutional conversion: how information becomes interpretation, priority, authority, coordinated action and learning.

It connects directly with the Diplomats.Digital Capability Framework, which examines whether ministries have the institutional conditions to turn signals into reliable action across headquarters, missions and relevant functions.

The practical question is whether important context remains available at the points where consequential decisions are made.

An institution does not need to reproduce every source in every briefing. It does need arrangements proportionate to the stakes, allowing relevant officials to understand what supports a judgment, who has interpreted it, who is authorised to act and what should happen if the evidence changes.

5. AI Adds a New Layer to an Old Problem

Artificial intelligence can make diplomatic information processing considerably faster.

It can assist with translation, summarisation, document comparison, information retrieval, pattern identification and exploratory analysis.

For foreign ministries working across languages, time zones and extensive mission networks, these capabilities can be useful.

The risks emerge when speed or apparent completeness is mistaken for reliability.

An AI system may produce a coherent summary that omits an important qualification. It may present repeated sources as independent confirmation, misinterpret context or generate a plausible reference that does not support the claim being made.

The challenge has three connected dimensions.

AI as an analytical tool. Institutions must determine which uses are appropriate, how outputs are verified and what level of human review is necessary before an AI-assisted finding influences consequential action.

AI as an information intermediary. Search, ranking, translation and summarisation systems increasingly shape what officials encounter and how they understand it. This raises questions about source accessibility, traceability, provider dependencies and the preservation of context.

AI as part of the information environment. Synthetic media, automated content production and AI-enabled influence activities create additional challenges for authenticity, attribution and information integrity.

Existing governance guidance provides useful starting points.

The NIST Generative AI Profile (2024) identifies risks and risk-management considerations across the AI lifecycle.

UNESCO's Recommendation on the Ethics of Artificial Intelligence (2021) addresses human oversight, accountability, traceability and the need to protect fundamental rights.

Neither document replaces the legal and operational judgment required within foreign ministries.

They reinforce an important institutional consideration: human involvement is meaningful only when people retain sufficient authority, information and practical ability to question or override a system's output.

A signature on an AI-generated briefing is not, by itself, evidence of effective oversight.

Similarly, a system that retains the source document but cannot explain how a material conclusion was produced may offer incomplete traceability.

One relevant technical precedent is the W3C PROV model, which provides a way to describe how information entities, activities and responsible agents relate to one another.

The model was not developed specifically for foreign ministries. Its underlying approach illustrates how information transformations can be represented and traced across systems.

The larger issue is institutional.

When a diplomatic judgment changes, can the institution identify the communications and decisions that still depend on its earlier version?

6. Illustrative DD Scenario: The Advisory That Outlived Its Evidence

An original Diplomats.Digital institutional decision scenario. All events, institutions and circumstances below are fictional.

A foreign ministry receives an early warning about possible restrictions in a strategically important maritime corridor.

A commercial monitoring platform reports an operational disruption. Several media outlets repeat the information, describing the corridor as closed.

An embassy prepares an assessment based on available sources.

It confirms that restrictions have been reported but finds insufficient evidence of a complete closure. The embassy explicitly records the uncertainty and recommends further verification.

At headquarters, an AI-supported system prepares a shorter briefing for an interinstitutional crisis team.

The summary states that multiple sources have confirmed the corridor's closure.

Two material details have been lost: the original uncertainty and the fact that several reports relied on the same underlying source.

Meanwhile, the transport ministry receives information from operators indicating that some vessels continue to transit the corridor.

The two ministries are now working from different assessments of the same situation.

Senior leadership requests a recommendation.

The first decision

The foreign ministry faces several possible responses.

It could issue a precautionary notice describing reported operational restrictions without claiming that a complete closure has been established.

It could seek confirmation through diplomatic and maritime channels.

It could provide targeted information to relevant operators while continuing verification.

The appropriate choice depends on urgency, possible consequences, available authority and the strength of the evidence.

A precautionary response may be justified even when a claim remains unconfirmed. The uncertainty should remain visible in the communication.

The evidence changes

Several hours later, the relevant maritime authority confirms that a temporary pilotage restriction has ended.

The corridor was never completely closed.

The embassy updates its assessment.

Yet the earlier briefing remains in circulation.

A second embassy uses the outdated summary in a commercial discussion. Another department retains the original warning. An automated information system continues to describe the closure as a current fact.

The original analytical question has been resolved.

The institutional consequences of the earlier assessment have not.

The review

During a subsequent review, the ministry establishes that the embassy's original report was appropriately qualified.

The error emerged when the assessment was summarised and circulated without its evidentiary limitations.

The review also finds that the institution cannot easily identify every communication or decision that depended on the outdated version.

No single participant needed to act irresponsibly for this situation to develop.

The failure occurred across routine institutional handoffs.

What the scenario reveals

The quality of an initial assessment and the reliability of its institutional use are related, but distinct.

A ministry can verify information carefully and still lose important context as that information moves between teams and systems.

Correcting the initial document is necessary. Effective correction may also require identifying which dependent communications, recommendations or decisions must be reviewed.

The scenario illustrates three practical requirements: preserve material qualifications, retain clear ownership of consequential transformations, and establish a route for corrections to reach the places where earlier information was used.

These requirements apply beyond maritime crises.

They matter in consular advisories, sanctions analysis, cyber attribution, public diplomacy, humanitarian coordination and negotiations.

They also apply when the initial transformation is performed entirely by people rather than AI.

7. The Evidence-to-Decision Continuity Test

The fictional scenario offers a practical way to examine a real institutional workflow.

Diplomats.Digital proposes an illustrative Evidence-to-Decision Continuity Test: seven questions that can help identify where context, responsibility or the capacity to correct a judgment may be lost.

This is a proposed institutional working test, not an internationally validated standard or a requirement to introduce seven new administrative procedures.

Existing document management, analytical, legal and crisis coordination arrangements may already perform several of these functions.

The test helps assess how reliably they connect.

A ministry can begin with one consequential workflow and one practical exercise.

For example, a crisis coordination team could simulate an initial warning, an AI-assisted summary, conflicting assessments from two institutions and a later correction.

The exercise would test whether participants can identify the authoritative assessment, preserve uncertainty, clarify approval responsibilities and trace which decisions require reconsideration.

The findings can inform targeted changes to existing procedures.

No new technology platform is required for the initial exercise.

Benefits and dependencies

Better evidence-to-decision continuity may offer several institutional benefits, but each depends on conditions that must be established and tested.

The objective is to make important responsibilities clearer without making already complex institutions unnecessarily bureaucratic.

There are limits.

Detailed records may create security and privacy risks. Confidentiality can be essential to diplomatic effectiveness. Access to sensitive evidence may be appropriately restricted. Some forms of professional knowledge cannot be fully documented.

The test must therefore be adapted to each institution's mandate, legal environment, security arrangements and operational needs.

Its value should ultimately be assessed through use, exercises and revision.

8. Knowledge That Survives the Individual

One of diplomacy's most valuable resources is also among its hardest to preserve.

An experienced diplomat may develop a sophisticated understanding of political relationships, informal influence, historical sensitivities and the difference between what an interlocutor says and what their government is likely to do.

Some of this understanding enters official reporting.

Some remains tacit, shaped by experience and relationships.

When the diplomat rotates to another post, the ministry retains the documents. It may lose part of the context that made them useful.

This creates a challenge for institutional continuity.

Diplomatic knowledge should be transferable enough to support successors without suggesting that professional judgment can be reduced to templates or databases.

A useful handover may preserve the assumptions behind an assessment, competing interpretations, unresolved questions and relationships that require careful contextual understanding.

Institutional learning adds another requirement: the ability to revise established assumptions.

James G. March's research on organisational learning examined the tension between refining existing knowledge and exploring new possibilities.

The relevance to diplomacy is substantial.

An institution may become highly effective at producing familiar reports while remaining less capable of recognising when its established way of understanding a situation has become inadequate.

A favourable policy outcome does not necessarily prove that the original assessment was strong. An unfavourable outcome does not necessarily mean that the decision was unreasonable on the evidence available at the time.

Institutions need to examine analytical quality, decision quality and subsequent outcomes separately.

This is also why institutional learning should extend beyond documenting lessons.

The more important question is whether those lessons change the next decision, exercise, handover or procedure.

For foreign ministries, the ability to retain and revise knowledge is part of operational capability. It supports continuity across leadership changes, mission rotations and technological transitions.

DD Looking Forward: Building Institutions That Can Revise What They Know

Foreign ministries have more ways than ever to observe international developments.

They can access public information from across the world, analyse large document collections, consult technical specialists, use AI-supported tools and exchange assessments with partners.

These capabilities will continue to evolve.

The institutional priorities are more enduring.

A ministry needs to know which claims are supported, which assessments remain provisional, who has the authority to act and how decisions should be reconsidered when conditions change.

It also needs room for professional judgment.

A fully documented process cannot eliminate political uncertainty. An algorithm cannot settle competing diplomatic objectives. A common assessment cannot remove every legitimate difference between institutions.

Reliable capability means being able to work through those differences while keeping responsibility clear.

For leaders considering where to invest, a useful starting point is a single question:

If a critical assessment changed tomorrow, would our institution know which decisions and communications need to change with it?

Answering that question requires examining the connections between evidence, interpretation, authority, coordination and learning.

The same question can guide a ministry reviewing its information systems, a diplomatic academy designing a crisis exercise or a mission preparing for a leadership transition.

Technologies will change. Analytical methods will continue to improve. Institutions will adapt to new sources of information and new forms of uncertainty.

The responsibility to exercise sound diplomatic judgment will remain.

The methods of knowing change. The responsibility for judgment remains.
