War is often described as a contest of force. It is also a contest of knowledge.
Who knows what is happening? Who knows what the other side intends? Which report is accurate? Which image is authentic? Which loss estimate is reliable? Which silence means nothing, and which silence means something? Which event is local, and which event reveals a larger change?
The strange feature of modern war is that information can be abundant while understanding remains scarce. Satellites, smartphones, sensors, social media, commercial data and continuous news feeds produce extraordinary visibility. Yet more information does not automatically produce more truth. It can produce more noise, more contradiction and more opportunities for manipulation.
The central information problem of war is therefore not simply collection. It is judgement.
War Creates an Epistemic Crisis
Epistemology is the study of knowledge: how we know what we claim to know. War puts epistemology under pressure because participants have strong incentives to hide information, protect sources, influence audiences, preserve morale and shape interpretation.
Even truthful information may be incomplete. A witness sees one street. A commander sees one sector. A government sees classified reporting but may still lack certainty. A journalist may have excellent local evidence but no access to strategic planning. A satellite image may show physical change without explaining intent.
This produces a hierarchy of uncertainty. Some facts are directly observed. Some are inferred. Some are estimated. Some are claimed by interested parties. Serious analysis keeps these categories separate.
The Fog of War Is Uneven
The phrase “fog of war” can sound as if everyone is equally confused. They are not.
Different actors possess different sensors, access, language skills, intelligence relationships, technical capabilities, local knowledge and decision authorities. A frontline unit may know the immediate terrain better than national headquarters. Headquarters may understand the wider political picture better than the unit. Civilians may understand local conditions that outsiders misread. An ally may know something one partner does not.
eduKateSG develops this idea in How War Sees | The Fog Is Uneven. The important lesson is that uncertainty has a geography and an institutional structure. Information is distributed unevenly across the system.
Data Is Not Intelligence
Data is a recorded observation. Intelligence is a reasoned judgement built from data, context, comparison and uncertainty.
A photograph is data. Knowing where and when it was taken requires verification. Understanding what it means requires context. Deciding whether it indicates a broader pattern requires comparison. Estimating what may happen next requires judgement.
This distinction is fundamental because modern systems can collect enormous amounts of data. The bottleneck often moves from collection to interpretation. Analysts must decide which signals matter, which reports conflict, which sources are independent and which apparent confirmations are actually copies of the same original claim.
More sensors can therefore create a new form of scarcity: not scarcity of observations, but scarcity of attention.
The Intelligence Cycle Is a Discipline of Questions
At a high level, intelligence work can be understood as a disciplined sequence: define what needs to be known, collect relevant information, process it, analyse it, communicate judgements and revise the question as new evidence arrives.
The sequence matters because bad questions produce expensive irrelevance. An organisation can collect perfectly and still fail if it collects the wrong things. It can analyse well and still fail if decision-makers do not understand confidence levels. It can communicate quickly and still fail if institutional culture punishes unwelcome conclusions.
Good intelligence therefore depends on organisational honesty. Analysts must be able to say “we do not know,” “the evidence is mixed,” or “our previous judgement was wrong.” In war, those sentences can be strategically valuable.
Secrecy Protects Knowledge but Can Also Trap It
Secrecy is necessary in war because sources, capabilities and plans can be damaged if exposed. But secrecy has costs. Information that is protected too aggressively may fail to reach people who need it. Organisations can become fragmented into compartments that each see only part of the picture.
This creates a permanent institutional tension: protect information enough to preserve advantage, but share it enough to enable coordinated action.
The tension exists beyond military organisations. Governments, intelligence services, police, emergency agencies, technology companies, journalists and humanitarian organisations all work with different disclosure rules. Coordination becomes difficult when one institution cannot reveal why it believes something.
Classification Changes the Shape of Debate
When important evidence is classified, public debate operates with an incomplete record. This does not mean classified claims are necessarily true or false. It means outsiders face an asymmetry: they may be asked to evaluate a conclusion without seeing all of its supporting evidence.
Democratic systems therefore depend on institutional mechanisms that can examine secret information without making everything public: legislative oversight, courts, inspectors, internal review and authorised auditing. Trust is stronger when secrecy is bounded by accountability rather than treated as self-validating.
Deception Exploits Expectations
Deception is as old as organised conflict. Its general purpose is to influence what another actor believes about reality. But deception is not simply “lying.” At the strategic level, it works through expectations, ambiguity and the limits of observation.
The safest way to study deception educationally is not as a manual of techniques but as a reminder about inference. Analysts should ask whether an observed pattern has alternative explanations, whether a source may be motivated to shape perception, and whether confidence is being driven by evidence or by prior belief.
The deeper lesson is defensive: the more certain we feel, the more important it is to ask what evidence would prove us wrong.
Propaganda Is Not the Same as Falsehood
Propaganda is communication designed to shape attitudes and behaviour for political purposes. It may use false claims, but it can also use selective truths, emotionally powerful framing, repetition, symbolism and omission.
This is why fact-checking alone is not enough. A statement can be factually correct while still being presented in a way that hides scale, context or comparison. Conversely, emotionally loaded material can feel persuasive before its factual basis has been established.
War increases the demand for simple narratives precisely when reality is least simple. Audiences want heroes, villains, turning points and certainty. Information systems reward speed and emotional clarity. The result can be a widening gap between what is shareable and what is knowable.
Rumour Fills Empty Space
Rumour grows when three conditions meet: the issue matters, reliable information is scarce, and people are anxious.
War produces all three.
Rumours can spread through communities because people are trying to reduce uncertainty. Sharing is often social rather than malicious: someone forwards a warning because they want to protect others. This is exactly why responsible public communication matters. Authorities that communicate slowly, inconsistently or dismissively leave a vacuum that informal networks will fill.
Trust therefore becomes part of information infrastructure.
Public Trust Is a Strategic Resource
A government can possess excellent technical information and still struggle if the public does not trust its communication. Trust is built before crisis through consistency, transparency about uncertainty, correction of errors and visible competence.
This matters because emergency instructions require receivers. A warning only works if people notice it, understand it and believe acting on it is worthwhile.
eduKateSG explores this wider civic problem in How Singapore Warns and Shelters the Public in a Crisis. The connection to war is not that every crisis is war. It is that trusted communication is a capability in its own right.
Open-Source Intelligence Changed Who Can Observe War
Commercial satellite imagery, public databases, ship and aircraft tracking, social media, geolocation, archived webpages and other open sources have widened access to evidence. Researchers, journalists and civil society groups can now examine events that once depended almost entirely on official reporting.
This is an important democratisation of observation, but it is not automatic truth. Open sources can be misdated, mislocated, edited, selectively presented or copied across many accounts. The same discipline still applies: provenance, independence, corroboration and uncertainty.
One of the most useful habits is evidence triangulation: asking whether genuinely independent routes point toward the same claim. eduKateSG develops that method in How Evidence Triangulation Works | When Independent Routes Point Toward the Same Claim.
A Thousand Reposts Are Not a Thousand Sources
Digital information creates a counting illusion. A claim may appear across hundreds of accounts while tracing back to one original post. Repetition can feel like confirmation even when no independent evidence has been added.
This is why source genealogy matters. Ask where the claim began, which accounts are merely repeating it, whether later reports add new evidence, and whether apparently separate sources share the same underlying origin.
In war reporting, independence is often more valuable than volume.
Images Feel Certain Even When Context Is Not
Visual evidence is powerful because seeing feels like knowing. But images answer only some questions. A photograph may show that something existed at some moment. It may not show who caused it, what happened before, what happened after or whether the caption is accurate.
Video has the same problem. Clips can be real but miscaptioned. They can be old but presented as new. They can show a genuine event while excluding nearby context. Verification therefore separates the authenticity of media from the truth of the narrative attached to it.
The disciplined reader asks two questions: “Is this media authentic?” and “Does it prove the claim being made?” Those are not the same question.
Numbers Need Provenance Too
Casualty figures, equipment-loss counts, displacement estimates, economic losses and territorial measurements can become central to public understanding. Yet wartime numbers are often provisional.
Good analysis asks who produced the number, what methodology was used, what period it covers, what is included or excluded, and whether later revisions exist. A precise-looking number can hide broad uncertainty. An approximate range can sometimes be more intellectually honest.
Precision is not the same as accuracy.
AI Makes the Information Problem Larger
Artificial intelligence can help process large datasets, translate languages, detect patterns and organise evidence. It can also generate convincing text, images, audio and video. This expands both analytic capacity and the surface for manipulation.
The important response is not to assume that everything is fake. That creates paralysis. The better response is provenance: preserve source history, verify media when possible, compare independent evidence, distinguish direct observation from model output and label uncertainty.
AI therefore increases the value of old disciplines. Source criticism becomes more important, not less.
Information Can Move Faster Than Institutions
A viral claim can reach millions before a government, newsroom or research organisation has verified it. Institutional caution is slower because evidence takes time. This creates a difficult public perception: the cautious actor can look less informed than the reckless actor simply because the reckless actor publishes first.
The solution cannot be to abandon verification. It is to communicate uncertainty more effectively. Institutions can say what is known, what is not known, what is being checked and when an update will follow.
Silence is sometimes necessary, but unexplained silence is easily filled by speculation.
Information Advantage Is Not Omniscience
Superior sensors, analytics or intelligence networks can create real advantage. They do not remove uncertainty. Systems fail. Signals are ambiguous. Human intentions change. Opponents adapt. Data arrives late. Models extrapolate from incomplete observations.
This is why robust strategy must survive imperfect knowledge. Plans that require certainty are fragile. Institutions need branches, contingencies and mechanisms for updating decisions when assumptions fail.
The deeper advantage is therefore not knowing everything. It is discovering error sooner.
The Receiver Matters
Information is only useful when it reaches someone capable of interpreting and acting on it. A warning ignored is not operationally equivalent to a warning understood. A brilliant analysis sent to the wrong decision-maker may have no effect. A public message written for experts may fail ordinary citizens.
This makes communication a receiver problem. Who is the audience? What do they already know? What can they do? What uncertainty do they need to understand? What action is expected?
War intensifies these questions because receivers may be exhausted, frightened, overloaded or operating with incomplete connectivity. Clarity becomes a form of resilience.
How Students Can Read War Information Responsibly
A strong reader can use a simple discipline:
- Separate observation from interpretation. What was directly seen, and what is being inferred?
- Identify the source. Who made the claim, and what access do they have?
- Check independence. Are multiple reports genuinely separate?
- Check time and place. Is the material correctly dated and located?
- Look for methodology. How was a number or estimate produced?
- Read beyond the headline. Does the underlying evidence support the strongest wording?
- Preserve uncertainty. “Unknown” is a legitimate category.
- Compare serious disagreement. What evidence would explain why credible analysts differ?
- Update. Early reporting is often revised.
- Avoid emotional forwarding. Urgency is not verification.
These habits are useful far beyond war. They are part of information literacy in any complex society.
Truth Has a Time Problem
In conflict, false certainty can be immediate while reliable knowledge takes time. Investigators may need access. Records may be incomplete. Witnesses may be displaced. Satellite imagery may need comparison. Institutions may release data only later. Archives may open years afterward.
This means historical understanding often improves after the event. The first draft of war is written under uncertainty. Later drafts benefit from documents, testimony and distance.
Students should therefore resist the idea that contemporary information is automatically superior because it is immediate. Nearness gives access to detail; time can give access to context.
The War Series: Four New Lenses
- How War Changes Time — mobilisation, tempo, delay and adaptation.
- How War Changes Distance — geography, reach, supply and the cost of moving power.
- How War Changes Information — intelligence, secrecy, deception and the problem of knowing.
- How War Changes Institutions — emergency power, industry, society and the difficult return to peace.
The Larger Lesson
War changes information because it makes knowledge consequential, contested and incomplete.
Secrecy can protect. It can also isolate. Sensors can reveal. They can also overwhelm. Propaganda can persuade without being entirely false. Open sources can democratise observation without eliminating error. AI can accelerate analysis while making fabrication easier. Institutions can possess data and still fail if they cannot communicate uncertainty honestly.
The mature question is therefore not, “Do we have information?” It is, “What do we know, how do we know it, how confident are we, and what would change our mind?”
That question is one of the strongest defences against the fog.
