Martial Arts and the Empty-Data Problem: When the Analysis Framework Looks Better Than the Truth

On a March evening in Chiang Mai, I opened a martial arts analysis file and found every data cell empty. No fighter names. No events. No organizations. A complete eight-dimension analytical framework, with six tables and dozens of criteria rows — but nothing inside each cell but blank space. I sat still in front of the screen for about ten minutes. Those ten minutes taught me more than a hundred fights I have watched.

Forty-three years of writing have taught me one thing: in sport, blank space is more frightening than numbers. A number can be wrong, and we can fix it. Blank space we tend to fill with belief — and belief with nothing behind it is the mother of every rumor. Data does not lie, but the people who read it do.

The awkward label

The most telling thing about that file was not any detail, but the label. It tagged the domain as "martial arts." But to analyze martial arts, one must first answer a question: is this modern professional combat sports, or traditional performance martial arts (taolu), or sanda?

These three have three different logics — and choosing the wrong one breaks the entire analysis that follows. The file stopped at a vague label and never classified. This is a mistake I meet again and again in sports journalism: people say "martial arts" as if it were a single sport. But MMA, boxing, kickboxing, Muay Thai, freestyle wrestling, BJJ and sanda are distant cousins with a common ancestor, not siblings in one house.

An MMA bout is decided by win record, finish rate, takedown defense and striking accuracy. A taolu form is scored on difficulty and performance, awarded by a panel of judges on a defined scale. There is no shared measure between the two. Apply the wrong "win — loss — finish rate" framework to a taolu form and the result is meaningless in a systematic way. It is not randomly wrong. It is wrong the way a mis-programmed machine is wrong.

We once thought speed belonged to the individual, until the system collapsed. In 2026, at Chiang Mai stadium, when I analyzed forty Thai 400m hurdlers, I made exactly the same labeling error: I called them all "athletics." But hurdling and flat sprinting are two different problems. My data columns only started to mean something when I separated hurdling out, and only then did I discover the athletes were skipping the first three-step acceleration phase. A wrong label breaks the frame; a wrong frame breaks the conclusion. And a vague label, pressed to answer, invites the analyst to invent what is missing.

Why blank space is honest

There is a temptation every writer has felt: when the frame is already beautiful, we want to fill it. A table has a cell for "fighter accuracy" — we invent a number. A column has a row for "finish rate" — we add a percentage. At a glance, no one checks.

I set a rule for myself years ago: when data is empty, write "insufficient information to assess," and leave the blank. Emptiness labeled honestly is worth more than a number filled in confidently. Interestingly, that file did exactly this: in every cell, instead of inventing, it wrote "insufficient information — cannot assess." It named no fighter, invented no transfer figure, staged no fake fight.

The problem lay elsewhere: an entire pipeline had failed before the file was even born, and that failure was hidden by the beautiful exterior of the analytical frame. In martial arts, a smoothly written analysis — with tables, with terminology, but no real data — will be read as truth; while a line saying "insufficient data" is read as a sign of incompetence.

Money and the four organizational tiers

If the file had data, here is what it should have said about the organizational tier. Professional martial arts is arranged in a clear hierarchy. The top tier is global-scale promotions, where exclusive contracts bind fighters to one house and where "title fragmentation" is used as a bargaining weapon. The middle tier is regional promotions with resources but no depth. The bottom tier is emerging promotions, where fighters must sign contracts longer than their own career. In boxing the system is more complex: four major bodies overlap, each with its own ranking, and fans are routinely confused by a fighter ranked high by one and low by another.

The key point: any martial arts analysis only means something when we know which tier the fighter stands in, who they signed with, for how long, and where the money goes. An athlete never falls from lack of strength, but because the structure around them cracked first. I have seen this in another sport: relay. In 2026, when a Southeast Asian 4x400m relay team collapsed in the heats, colleagues blamed the retired star. I counted their baton-passing sessions in a week: two, against the opponent's five. The collapse was not in one person's legs, but in the whole system's training schedule.

Health, weight and rules

At the health tier, martial arts carries a burden the scorecard never reflects. Fighters accumulate blows to the head over the years. Number of fights, number of knockouts, number of times stepping onto the canvas while concussed — these are numbers that never appear in a record but decide a person's long-term future. A fighter's body ages not only by the calendar, but by the blows taken.

Weigh-in is a grey zone of the rules. The window between the weigh-in and the fight is usually twelve to thirty-six hours, allowing rehydration. A fighter can cut below their division, then rehydrate to step in five to ten kilograms heavier than the opponent. By the rules, nothing is wrong. Medically, it is a physiological shock with risks of severe dehydration, kidney damage and cognitive decline. This is the most easily overlooked metric in analysis, because it does not sit on the record; but it explains why a fighter looks weak in round one and explodes in round three. Chiang Mai taught me that numbers keep secrets better than people do — and weight is among the best at keeping secrets.

The counterintuitive view

The common assumption is: the more detailed the analysis, the more trustworthy. In martial arts this is often false. An analysis can be worthless from its very first data cell, if that cell is unverified. Detail does not mean accuracy; on the contrary, it often hides the lack of data behind a formal shell.

In the other direction, a line saying "insufficient information" is often read as a confession of weakness, but it is the most professional sign. There is a deeper layer: in martial arts, the audience's emotion is a real data source. Emotion, hard to measure, is the best diagnostic signal of what the audience will pay for, and money follows emotion faster than it follows technique. That is the paradox of the trade: an analyst honest about technique may be less famous than a confidently predicting one.

My vantage point

I was born in Vietnam, have worked over twenty years in Thailand, and must say this at the start of every martial arts analysis, because it concerns my vantage point. I stand between two martial arts traditions. Muay Thai is Thailand's national sport and carries huge cultural pressure on any analysis of it. Vietnamese martial arts, from traditional to modern combat, follow a very different trajectory. When I write about Asian MMA, I must remind myself that my impression of "regional identity" may be a prejudice — and prejudice, even unintentional, is still an organized form of invention. I once had to publicly correct my own belief about Southeast Asian martial arts, after real data at Chiang Mai stadium showed me the problem lay in selection systems and sustainable funding, not in talent. An empty stadium is the greatest mirror for the sports industry — look into it and you see for whom you exist.

A thought to take away

Faced with a beautiful table and an honest blank, the martial arts industry usually chooses the table. Fans want numbers, sponsors want drama, newsrooms want content. A blank satisfies no one.

But every time a writer decides not to fill the blank, they keep the reader's trust for next time. The sports industry will not collapse from a lack of rumors; it will collapse from a lack of people willing to say they do not yet know. Every record is written in the ink of conditions — only the naive believe in forever. In martial arts, where drama sells tickets faster than technique, daring to leave a blank is harder than daring to issue a title.

A question for the reader: when you read a martial arts analysis full of numbers and full of confidence, do you ever ask yourself where those numbers came from — or whether they were simply placed there to fill the blank?
