The "Martial Arts" Label and the Empty Chair in Vietnam's Sports Classification System

Inside an internal dataset, there is an empty field. That field was supposed to define the subject class under analysis: modern combat sport, where results are scored by rounds, margins and finish rates; traditional martial arts, where scores are built from difficulty and performance value; or sanda, where a single clean strike can end the bout. Instead of three clear directions, the field carries one label: "martial arts".

An empty chair never lies — it only exposes what we would rather not hear. A blank label is not neutrality. It is an admission that the classification system stopped working long ago, and that nobody in the production chain noticed.

In 2026, at a World Cup group-stage match in Russia, I mispronounced Luka Modrić's name three times in the first half. Nobody corrected me on air. The system only reacted once social media had already reacted hours earlier. The lesson was not that I was wrong, but that the system only repairs itself when it has been seen. With a blank classification field, there is nothing to see, and therefore nothing to fix.

I read one name wrong, but the system has read all of us wrong. That is why I began paying attention to empty chairs in sports data — not because they cause errors, but because they prove the error existed before anyone typed a word.

In Vietnam, the term "martial arts" is used so broadly that almost nobody treats it as a problem. A SEA Games bulletin can group taekwondo, judo, boxing, karate, pencak silat, wushu and vovinam under "combat disciplines". It is convenient for headlines, for bundling stories, and for counting medals. But it erases the single most important fact: each discipline runs on its own scoring logic, and that logic determines how an athlete is measured, coached and selected.

The SEA Games 31 held in Hanoi in 2026 is the clearest example I have sat through. On the same competition day, I watched wushu taolu in the morning and sanda in the afternoon. Two sessions, two entirely different evaluation systems, filed under one name. In the morning, athletes walked onto a stage alone, judged on difficulty, precision of posture, rhythm and expression. No opponent, no rounds, no finish. In the afternoon, two fighters stepped onto a platform where everything turned on distance, tempo and timing. One side was scored by an artistic eye, the other settled by contact.

When I asked a young coach why both sat in the same selection category, he answered honestly: "Because both are wushu." That answer is administratively correct and professionally wrong. It confirms something I have recorded for years: labels are not designed to describe essence. They are designed to allocate resources, schedule events, and assign responsibility.

Every mispronunciation is a system trying to say something. A wrong label is no different. When a system calls taolu and sanda the same thing, it is saying it does not want to distinguish. And when a system does not want to distinguish, the person who pays is always the one training inside that label.

I have spent most of my career covering Olympic sports and athletics, where scoring logic is transparent to the point of cruelty: time, distance, height. A 100-metre race leaves no room for subjectivity. Combat sport and martial arts are different. There, most of the value sits in what a stopwatch cannot capture, and that is precisely why misclassification becomes dangerous. When you cannot measure with numbers, you must classify with language. When the classifying language breaks, the entire system of perception around that discipline breaks with it.

Wushu taolu athletes can earn near-perfect scores without striking anyone, because there is nobody to strike. Results come from the combination of judges' technical marks and difficulty value. In sanda, the same athlete, in the same uniform, is judged by clean scoring contacts, by knockdowns and pushes off the platform, and by finishing situations. Two logics, two selection pipelines, two completely different physical models.

Apply round-based, margin-based, finish-rate logic to a forms routine and you will conclude the athlete "has no combat record". Apply difficulty and performance logic to a sanda bout and you will conclude the fighter "lacks aesthetic posture". Both conclusions are meaningless, yet both can appear in print and both can shape a federation's investment decisions.

I once saw an athlete marked down in a technical report purely because the report applied the wrong framework — using a "combat win rate" criterion to evaluate a forms practitioner who had never needed to compete in combat. Applying the wrong analytical frame produces systematically wrong conclusions, not random ones. Random errors get caught and corrected. Systematic errors get repeated, and once repeated long enough, they harden into default truth.

Three logics cannot be swapped. Modern combat sport runs on outcome logic. Forms disciplines run on execution logic. Point-scoring combat sports — judo, karate, taekwondo sparring, pencak silat — run on accumulation logic within a time limit. A model that works for boxing fails for poomsae. A model that works for poomsae means nothing in MMA. When a newsroom files all of them under "martial arts", it automatically selects the wrong frame for at least two of the three groups.

The counter-intuitive point is this: the industry's default response is to demand more data. More metrics, more tables, more columns, more algorithms. The real problem is that we measure before we classify. We collect indicators before deciding which indicators mean anything in which discipline. We count without defining.

An empty column is not missing data. It is a signal that the column should never have existed. When someone fills a zero into the "combat win rate" column of a forms athlete, that zero says nothing about the athlete. It says something about the person who designed the table.

Vietnamese sports media carries a structural error, and the error is not a lack of resources. It is the habit of classifying by administration rather than by technical essence. Federations group disciplines to manage budgets. Newsrooms group them to schedule coverage. Both groupings exist side by side, serve different purposes, and neither is designed to describe the sport accurately.

The frightening part is durability. A random error disappears once someone catches it. A systemic error reproduces itself every season, every recruitment cycle, every budget line. It becomes the foundation. Once it is the foundation, fixing it is no longer fixing an article — it is changing how an entire system sees itself.

I do not think that is impossible. I only think it does not start with adding data. It starts with admitting there is an empty field, and asking why it stayed empty so long without anyone noticing.

At 49, what two cultures have taught me is this: every system has a dark side. The shared feature is not laziness. The shared feature is that clear classification costs effort, while vague classification costs nobody accountability.

So I offer no firm conclusion. I offer a diagnosis, and leave the empty chair to keep exposing.

An empty season is not short of spectators — it is short of data about the heart. And a system short of data about the heart is usually very confident about the numbers it does not understand.

I still keep the note-taking habit I formed in 2026, when I was the only female commentator in the press room at a Rajamangala Asian Cup qualifier. That night I did not argue with the man who laughed at me. I simply charted one midfielder's movement for ninety minutes. Those notes were later cited because they were precise, not because they were loud.

That approach works for a classification label too. I do not need to shout that "martial arts" is a meaningless category. I only need to place three columns side by side — one for sanda, one for taolu, one for point-scoring combat — and let readers see that the three cannot share one ruler.

When three columns cannot share one ruler, merging them under a single label stops being simplification. It becomes erasure. What I want to leave behind is not a solution but a way of looking: the next time a bulletin lists "combat disciplines", ask which were settled by contact, which by difficulty, which by accumulation. If the bulletin cannot answer, the problem is neither you nor the athletes. The problem is the field nobody has filled in.

After 33 years observing this industry, one belief holds firm: a mature sporting nation is not measured by medals. It is measured by its ability to describe itself accurately. The empty chair is still there. Nobody sits in it, but it is still speaking.
