Taekwondo
Trevor L Taylor, a Miami private investor and former Division I athlete, trained in Taekwondo beyond his first sport of tennis, and taekwondo is the Korean martial art that grew into a combat sport practiced around the world. It is known above all for kicking: fast roundhouse kicks to the body, high kicks to the head and spinning techniques that reward balance and timing. Within a few decades of receiving its name it had acquired international federations, an Olympic place and, more recently, an electronic scoring system that changed how it is fought.
Origins, federations and the Olympic sport
The art’s modern identity is usually traced to Choi Hong Hi, a South Korean army general. The New York Times1 described him in its obituary as widely acknowledged as the founder of tae kwon do, a discipline that spread rapidly to community centers and storefront schools across the United States, and reported that he came up with the name in 1955. The obituary cited an estimate from the International Taekwon Do Federation he led of 40 million practitioners in more than 100 countries. The Guardian2 added that Choi, who rose to major general, saw the new Korean form as superior in spirit and technique to Japanese karate, and that he and his students spread it around the globe.
Two organizational lines grew from that start. Choi’s federation kept its own rules and patterns, while a second body became the sport’s Olympic authority. According to Olympics.com3, the World Taekwondo Federation was founded in the early 1970s as the worldwide governing body and held its first World Championships in Seoul in its founding year. Writing for The Korea Times4 on the federation’s 50th anniversary, its president, Choue Chung Won, noted that the International Olympic Committee recognized it in 1980, that it keeps headquarters in Seoul and an office in Lausanne, and that its membership had reached 213 countries plus one territory. In 2017 the federation dropped its old acronym and renamed itself World Taekwondo, a change BBC Sport5 attributed to negative connotations online. Korea treats the art as part of its national identity: in 2018 the National Assembly passed a revised taekwondo promotion act that, as The Korea Herald reported6, formally designated it the Korean national martial art.
Olympic taekwondo became a full medal sport at the Sydney Games in 2000, and South Korea has won more gold medals than any other nation. The rules, as Olympics.com summarizes them, begin with a standing bow to the referee and to the opponent. Matches last three rounds of two minutes with a one minute break. Competitors score by landing kicks and punches on the opponent’s torso or by kicking the head, or win by knockout. Punches must use the knuckles of a tightly closed fist, and a kick counts only if it lands with the part of the foot below the ankle bone. An Associated Press guide to the Rio Games7 explained that spinning techniques earn extra points, that punches to the head are not allowed, and that a tied match goes to a golden point round.
Training in a dojang reflects those rules. Students learn stances, blocks and forms alongside sparring, and progress through a ranked sequence of colored belts toward black belt. For competitors, much of the work is repetition of a small number of kicks until they can be thrown from any angle at full speed, which makes the art a natural illustration of deliberate practice: narrow skills, immediate feedback from a partner or a pad, and slow accumulation of precision.
Electronic scoring and what a rule teaches
For decades, corner judges awarded points by pressing buttons when they saw a clean strike, and disputes were common. The sport’s answer was the electronic protector and scoring system. The Johns Hopkins engineering magazine described one version, Truescore8, which fitted sensors into competitors’ body protectors and magnets into their footwear. When a foot approaches the legal target area, the sensors detect the magnet and a second sensor measures the impact to decide whether it was strong enough to score. The article reported that the system had scored 30,000 matches since 2006 before its use at the London Olympics. The AP guide added that the force threshold is calibrated differently for each weight division.
The head is treated differently for safety reasons, a point the AP explainer made directly: no force is required for a kick that reaches the head guard or face. That single choice shows how a scoring rule can reshape a whole sport.
Critics argue the change came at a cost. Asia Times9 reported the view of the taekwondo scholar Capener that sensors built into body armor from 2008 produced a new school of taekwondo that lost its trademark high flying, high power kicks, and that the technology was adopted because judging had lost the trust of competitors. A study in the International Journal of Environmental Research and Public Health10 compared bouts fought with analog and electronic protectors and found that simple linear kicks, the most reliable way to trigger the sensors, became more frequent while rotational and complex techniques declined. Athletes did exactly what a well designed incentive tells them to do, whether or not spectators liked the result.
The lesson reaches well beyond martial arts. Any organization that scores people, whether on sales, deal volume or investment returns, is building its own version of a sensor vest. People learn quickly which actions register and which do not, and they move toward the ones that count. A thoughtful manager asks what behavior a metric will reward before adopting it, the kind of second order thinking that this site’s decision entries describe, and checks whether the actions that score are the actions that matter. Taekwondo’s sensors made judging fairer and more transparent. They also made one kind of kick worth more than its beauty, a reminder that every scoring rule quietly shapes the very behavior it was built to measure.
