Insufficient Evidence: The Forgotten Principle Behind Every Refereeing Controversy

Insufficient Evidence: The Forgotten Principle Behind Every Refereeing Controversy

Opening

The 94th minute. The referee stands at the edge of the penalty area, one hand on his earpiece, eyes fixed on the big screen in the corner of the stadium. Three camera angles are replayed in sequence. None shows a clearly conclusive handball. Four minutes later he drops his hand, points for a corner, and lets play continue.

The on-field decision stands. Not because the referee was right. Because nobody could prove him wrong.

I recorded that moment in my notebook the way I record every contested incident: time, situation, shirt numbers involved, evidence threshold, verdict. Then I opened another file — the data extraction for an analytical piece assigned to me that week.

Title: blank. Source: blank. Information points: none. Entities involved: unidentified. Time sensitivity: not assessed.

Four minutes before the VAR screen, I thought I was watching a difficult incident. After opening the file, I understood that the hardest situation in this job is not the ambiguous incident. It is the incident that does not exist.

Context

To understand why an empty file is worth writing about, you have to go back to how football defines evidence.

Football's laws contain no concept of maybe. In the penalty area, the ball either touches the hand or it does not. A player is either offside or not. Referees can be wrong, but the law itself leaves no room for vagueness. The vagueness lives on another level: the threshold of evidence required to overturn a decision already given.

IFAB sets that threshold in four words: clear and obvious error. The default always tilts toward the on-field decision. The referee does not have to prove he is right. Whoever wants to change the outcome must prove he is wrong — and must do so with images, not feelings.

I learned that principle later than I expected. On my first day on the job, I thought my work was to deliver conclusions. A few years later I understood that my work is to check whether there is enough basis to deliver a conclusion at all. Those are very different tasks, and most mistakes in this profession come from merging them.

The extraction I opened that day had nine sections. Tactical and technical analysis. Club finance and the transfer market. Results and the public-opinion cycle. League landscape and team positioning. Rules and compliance. Management and the dressing room. Risk profile. Media narrative and expectations. Football industry transmission.

Nine sections, each with tables, columns and rows. Cells assessing tactical sophistication, cells comparing squad value, cells modelling sanctions across worst-case, central and optimistic scenarios. A complete, professional, high-grade analytical structure.

And every cell said the same thing: insufficient information.

No club was named. No player was mentioned. No transfer fee, no expected-goals figure, no possession share, no date to cross-check against.

To a football reader, such a file looks like a failure. To a practitioner, it is a result. This is where I want to slow down.

Core

The on-field decision stands — and that is a conclusion, not an evasion.

In football, insufficient evidence is one of three valid verdicts. The other two are uphold and overturn. A referee is never marked down for concluding there was nothing to overturn, provided he looked at everything he needed to look at. By contrast, a referee who overturns a decision purely because of crowd pressure drops a grade in the match supervisor's report the same evening.

The same principle applies to writers. When a file has no title, no source and no entities, the only honest verdict is that there is insufficient information to judge. Every other sentence — this team presses high, that club has financial problems, the coaching staff is losing the dressing room — belongs to the category of verdicts without evidence. In football, those are the verdicts that get reversed fastest and hurt most.

The same incident, two ways of blowing the whistle — the law is never ambiguous, only the person holding the whistle is. I first wrote that line after a four-hour argument with a colleague about an offside call. I still use it, but now in a broader sense: the ambiguity sits neither in the law nor in the data. It sits in the moment someone decides on a conclusion before collecting enough data.

I have a professional rule I have enforced on myself since 2026: never publish a tactical claim without at least three concrete data points behind it. Three figures, not three impressions. That rule was born from a near-miss.

In 2026, when European leagues returned after their shutdown, UEFA allowed five substitutions per team while the Premier League kept three. I was assigned a two-thousand-word analysis of that inconsistency. My first draft flowed beautifully: different rules create different advantages, teams with squad depth benefit, elite football is entering an era of rotation. Reading it back, I realised I had not a single number to support any of it. It was all plausible-sounding inference.

I scrapped the draft and spent one hundred and twenty hours rewatching ten Bundesliga matches — the league that had adopted the five-substitution rule. I logged every substitution by minute, by scoreline at the time, by the position of the player coming on. The result: an average of 3.2 substitutions per match fell between the 60th and 75th minute. That figure turned a hunch into an observable sample. Four days later the piece ran, and its structure was entirely different from the first draft: rule first, data second, conclusion last.

The lesson was not that data matters. Everyone knows that. The lesson was that where data does not exist, the claim must not exist either. The pandemic taught me that rules also need to breathe. But it taught me something else too: when the rules breathe, the writer must hold his own breath and keep checking.

There is another kind of data I now verify twice before publishing: names. In 2026, as an intern, I live-reported a group-stage match between France and Saudi Arabia and misnamed the forward Amine Gouiri four times in the first half alone. The editor corrected it and reprimanded me sharply. Afterwards I spent two weeks rewatching group-stage footage to memorise the names and shirt numbers of one hundred and twenty players.

Since then I keep a private data sheet with FIFA-standard romanisations of player names. Before publishing, I cross-check name, shirt number and position at least twice. It sounds excessive for something so small. But the first mistake is not there to be erased; it is there to be cross-referenced later. A misspelled name is not a typo. It is evidence that the writer did not check the source. And once a reader catches one wrong name, they have every right to doubt every remaining number.

By 2026 I was employed full-time at a sports outlet in Shenzhen. World Cup quarter-final: Portugal against Morocco. Morocco won 1-0 through Youssef En-Nesyri in the 42nd minute, with goalkeeper Yassine Bounou keeping a clean sheet under late pressure. I spent forty-eight hours rewatching the footage to analyse how Morocco broke their opponent's pressing rhythm, with a running load of roughly 11.4 kilometres per player per match.

I wrote three thousand five hundred words on Morocco's out-of-possession 4-1-4-1: a back four holding an extremely short horizontal distance, a midfield four sealing the internal passing lanes, a single pivot sweeping behind. The editor asked me to cut it to one thousand five hundred words because readers need information fast. I learned to compress the entire analysis into five points, each tied to one number, and published within two hours.

A high defensive line is a bet; I only record the moment the gambler shows his cards. Portugal pushed up chasing an equaliser, and the price was the space behind their back line. Morocco did not need possession to win. They needed one gap, at one moment.

I tell these three stories not to talk about myself. I tell them to show that every correct conclusion in this job rests on a volume of verification far larger than the conclusion itself. A twenty-word claim can require forty-eight hours of tape. A single figure like 3.2 can require one hundred and twenty hours. A correct name can require two weeks of memorisation.

Which brings the empty extraction back into the story.

The tactical table in that file has four rows: sophistication, execution, personnel fit, key data. All four say insufficient information to determine. That sounds meaningless, but it is in fact a precise diagnosis. You cannot assess the sophistication of a tactic when you do not know whose tactic it is. You cannot assess personnel fit without a squad. You cannot discuss key data without expected goals, without PPDA, without possession share.

The finance table is the same. Broadcast revenue, commercial revenue, wage bill, net debt — four cells, four blanks. A financial balance sheet needs at least one cost figure and one revenue figure. Without both, any claim about sustainability is a guess dressed in terminology.

The risk table is where I paid most attention, because it shows the limits of the method most clearly. The risk matrix has six categories: sporting, financial, personnel, rules, public opinion, systemic. Each needs a level, a likelihood, an impact and a mitigation. No entity, no risk. You cannot model a worst-case scenario for a club that has not been named.

This is the point many football writers skip: risk is a property of an entity, not of a topic. Without a subject there is no risk. With a subject but no data, the risk still exists — it simply cannot be measured, and those two states must be recorded differently.

The industry transmission section returns the same result. The transmission diagram has three layers: upstream academies and talent supply, midstream clubs and competitions, downstream broadcasting, commercial and derivative markets. An event only travels along that diagram if it has a point of origin. No origin, no transmission path.

And the media narrative section — which I consider the most important of the nine — is also empty. It asks three questions: what is the current narrative, which phase of the cycle is it in, and how much of the heat is generated by social accounts rather than underlying data. None of those can be answered when no narrative has been supplied.

There is one distinction I want to make clearly here, because it is routinely misunderstood. Insufficient information is not the same as inconvenient information.

Inconvenient information is when the data exists but does not match the original hypothesis. That was the 2026 substitutions piece. The data existed; it simply did not support the elegant angle I wanted to write. The writer has two options: revise the conclusion, or discard the data. Choosing the second means forfeiting the right to write about that subject ever again.

Insufficient information is when the data does not exist. There is no conclusion to revise, because no conclusion ever stood. In that case the writer has exactly one honest option: stop and state that no verdict is possible yet.

Confusing these two states is the origin of most bad content in this industry. Writers meet the second state and treat it as the first. They fill the gap with inference, turn a shortage into an ambiguity, then turn the ambiguity into a verdict that appears to balance both sides. It is the escape hatch of someone who will not commit.

I do not accept that escape hatch. A writer who works to a process and prioritises accuracy at speed cannot end an article with both sides have a point. There must be a final answer. And when the data does not permit an answer, the final answer is precisely: there is not yet enough basis for a verdict.

In other words, decisiveness is not always having a conclusion. It is always stating clearly where you stand on the evidence ladder.

There is one professional pressure that erodes this principle, and I meet it every week: the pressure to publish. An empty file still has to become a product. A vague topic still needs a headline. A match with nothing notable still needs a report.

That pressure does not come from readers. Football readers, in my experience of watching the market, are a fairly sharp audience. They spot quickly when an analysis is just a match report rewritten in ornate language. The pressure comes from operations: metrics, frequency, speed. And that pressure produces a type of product more damaging than outright false news — a product accurate in its facts but wrong in its weight.

I call it conclusion inflation. A small detail gets inflated into a trend. One match gets elevated into a tactical turning point. A press-conference remark gets read as a signal of a collapsing dressing room. None of those sentences is factually false. But the whole structure is false, because the weight of the conclusion far exceeds the weight of the evidence.

In football, this is the equivalent of awarding a penalty from a camera angle that never shows the foot. Nobody says the player did not foul. It is simply that nobody saw it.

I believe in the naked eye, but VAR taught me that the naked eye also knows how to lie. My eye sees the incident the way I want it to have happened. The camera has no desire. That is why the observation process must be designed to work against the observer, not to serve his instinct.

The nine sections of that empty extraction are exactly such a process. They do not let me hide in a single angle. They pose nine independent questions, and all nine demand entities, figures, sources. When all nine return the same status, the conclusion stops being a personal choice. It becomes the output of a process.

Contrarian Angle

This industry pays for confident conclusions, not correct ones. I have to admit that, even though it runs against everything I have written above.

An article claiming Club X has lost the dressing room will be shared many times more than one saying there is not yet enough basis to claim that. A headline with a verdict always beats a headline with a limitation. Search algorithms lean the same way: they reward clarity, decisive answers, quotable content.

But here is the counter-intuitive part. The greatest information value in football does not lie in correct conclusions. It lies in fully recorded negative results. A correct conclusion only confirms what was already known. A negative result reveals the limits of the method — and the limits of the method are the only thing that stops a writer repeating an old mistake.

In medicine, failed trials are still published, because otherwise hundreds of research teams would walk down a road that has already been blocked. In football, we hide negative results and treat that as professional strength.

The consequence is that every season the same unsupported claim reappears, under a new name, at a new club. Nobody can cross-check against last time, because last time was never recorded.

There is one detail in that extraction I consider more important than the rest: the top-priority risk warning, rated high, stating that analysis based on empty input could lead to fabricated conclusions. It is a self-warning. The system protects itself from its own user.

Football has had this kind of self-protection for a long time; we simply rarely see it as a structure. Every time an assistant referee raises his flag and the referee waves play on, that is self-protection. Every time VAR checks twelve angles and upholds the decision, that is self-protection too.

The writer's problem is never a lack of tools. It is a refusal to switch them on.

Takeaway

If I could propose one change, it would be a public evidence standard for football writers, modelled on the way IFAB sets the VAR threshold: every tactical claim must carry at least three verifiable data points; every claim about personnel must cite a traceable source; every financial claim must carry a figure with a unit.

And when all three are missing, the correct answer is not a vague article. It is a short line stating that the file does not yet contain enough data for a verdict.

Discipline is not there to punish; it is there so the match can continue. The insufficient-evidence principle works the same way. It is not designed to silence writers. It is designed so that every conclusion published later still holds up.

And to you, the reader who made it this far: the last time you saw an analysis deliver a confident verdict about a club without a single number behind it, how long did you believe it?
