Fake martial arts: The psychology behind 'no-touch' knockouts
What leads people to believe in "chi" attacks and "no-touch" knockouts?
- A small fraction of martial arts teachers claim to possess extraordinary powers, like being able to knock out opponents without touching them.
- A recent video essay explores the psychological factors that drive people to believe in fake martial arts.
- These factors might also help to explain why there's often some degree of blind self-deception regarding the efficacy of traditional martial arts.
Outside of traditional martial arts lies a strange world where energy attacks and "no-touch" knockouts replace punches and kicks.
You can get a glimpse of it through YouTube videos showing fights that more closely resemble "Dragon Ball Z" than real-life combat. Take, for example, practitioners of the Balinese martial art Yellow Bamboo, who believe they can blast their opponents with God-charged beams of "chi" (it doesn't fare well against non-believers). Or George Dillman, the "no-touch" master who seems to have convinced dozens of his students that he could knock down — and even knock out — opponents without touching them.
And then there's Yanagi Ryuken, a Japanese man who claims to have psychic abilities, and has been described as a master of Daito Ryu Aikido. Here he is deftly defeating a flock of his students.
In 2006, Ryuken, who was 65 at the time, accepted a challenge match against 35-year-old Iwakura Tsuyoshi, a Japanese journalist and mixed martial artist. Here's what happened:
Ryuken said he lost because his psychic abilities were temporarily weakened due to illness. It's impossible to know whether Ryuken's faith in his own psychic abilities was pummelled that day, but he reportedly continued to train students in his special style.
In any case, it's a brutal sight. It also highlights the darker, not-so-funny side of fake martial arts: people looking to defend themselves are being sold shoddy techniques that fail in real-world fights.
Why do people buy into fake martial arts?
In a recent video essay, YouTuber Super Eyepatch Wolf explores that question by taking a look at the history of fake martial arts, and some of its noted "masters."
The 30-minute video is well worth a watch. If nothing else, check out the last segment, which outlines the story of Xu Xiaodong, a Chinese mixed martial artist who's spent years challenging and defeating fake martial arts teachers. In response, the Chinese government lowered his "social credit" score.
Super Eyepatch Wolf notes that fake martial arts groups are similar to cults, in that both promise "simple human comfort" and protection from fear. In the case of martial arts, that fear is physical violence from others.
"This was the same psychological manipulation that let Charles Manson control his followers, making them act in strange, bizarre ways, and even commit murder," Wolf says, noting that the same promise of comfort and community also enabled members of the Heaven's Gate cult to commit mass suicide.
Similar to cult leaders and "no touch" masters are so-called "faith healers," like Benny Hinn. With all three, Wolf notes, the formula boils down to: "Put all your faith into this one individual, and they will give you the means to guard yourself from the evils of this world."
"...there's a tremendous amount of comfort in that, the idea that these people can teach you techniques that will make you immune from physical danger, creating an illusion so strong, it's led to these kinds of footage we've been looking at..."
But what about traditional martial arts? Might a similar, yet subtler, form of self-deception about the true strength of students' or teachers' abilities also occur in, say, karate or Wing Chun dojos?
In a 2012 blog post, neuroscientist and author Sam Harris suggests two ways that mainstream martial artists come to delude themselves regarding their abilities. One is that training occurs in a controlled, predictable environment, and so learned techniques can become a "mere pantomime of combat that does little to prepare a person for real encounters with violence." Also, some techniques are too dangerous to perform in a dojo, so practitioners just assume that they'd be effective in a real fight, even though "reports from the real world suggest otherwise."
An even deeper dive into self-delusion in the martial arts comes from a 2010 paper written by Gillian Russell, a philosophy professor at the University of North Carolina at Chapel Hill. Russell's key argument is that martial arts tend to encourage "epistemic viciousness," which she defines as the "the possession of vices that make one bad at acquiring true beliefs, or give one a tendency to form false ones."
To summarize, Russell describes several factors that might encourage bad beliefs among martial artists, including:
- The dojo acts like a church. For example: Members feel guilty if they don't go; social norms and dress codes are moralized; practitioners treat the art as sacred, unquestionable.
- The problem of investment. Both teachers and students often invest a lot of time and resources into one specific practice. This investment makes them less likely to entertain evidence that their specific techniques might not be effective, or that there might be another martial art that is superior.
- Students must rely on a teacher. It's impossible to learn martial arts online or from a book; students need an authority to teach them. This inevitably means there will be a period during which students can't accurately judge whether their teacher is teaching effective (or safe) techniques. Also, most martial arts are hierarchical, requiring students to show deference to teachers and senior members. This submission may cause students to put more stock into certain beliefs.
- The art appeals to history and tradition. "Just as there is a tendency to defer to seniority in the martial arts, so there is a tendency to defer to history," Russell writes. She notes that many martial arts promote too much "epistemic deference" to old teachings, while being unwilling to incorporate new techniques or information. She then draws a comparison: "If you tell a long-distance runner that Pheidippides, the original marathon-runner, said that athletes should not spend time thinking about their equipment, but should focus their minds on the gods, he might say something like 'oh yes, that's interesting' but he wouldn't infer that he should stop replacing his running shoes every 400 miles. Runners think that the contemporary staff of Runner's World know more about running than all the ancient Greeks put together."
Of course, traditional martial arts can provide people with real self-defense skills, discipline, and a sense of aesthetic beauty and community. But martial arts also illustrate how blind spots can cloud judgement. After all, the physical, mental and emotional stakes are high in martial arts, not to mention that martial artists invest tons of time and money into training.
Altogether, these conditions may make people more vulnerable to cognitive biases: Practitioners want to believe what they're doing is effective, that they'll be protected from outside threats, and that their community is on the right path, even if evidence says otherwise.
Obviously, blind spots aren't limited to martial arts. As Russell notes, you can see similar phenomena in a parent who thinks her kid is an unrecognized genius, or in spouses who wildly overestimate how attractive strangers would rate their husband or wife.
"The last case, in particular, might tempt us to think that some epistemic vices are sort of cute. But it would be stupid to believe that epistemic vice is acceptable in the martial arts, since this is an area where it is morally important to have true beliefs, and not just cute ones," Russell writes. "The question of whether you can stop a train with your ki, or whether a stretch will be detrimental to your students' health, or whether a technique could kill someone—these are not questions on which you should want to be endearingly mistaken."
Northwell Health is using insights from website traffic to forecast COVID-19 hospitalizations two weeks in the future.
- The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
- The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
- Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.

For example, if the tool forecasted a surge in COVID-19 hospitalizations in two weeks, Northwell Health could begin:</p><ul><li>Making space for an influx of patients</li><li>Moving personal protective equipment to where it's most needed</li><li>Strategically allocating staff during the predicted surge</li><li>Increasing the number of tests offered to asymptomatic patients</li></ul><p>The health-care field is increasingly using machine learning.

"I think [Northwell Health's new predictive tool] really is a great first example of how we should be attacking a lot of things as we go forward."</p>
Making machine-learning tools openly accessible<p>Northwell Health has made its predictive tool <a href="https://github.com/northwell-health/covid-web-data-predictor" target="_blank">available for free</a> to any health system that wishes to utilize it.</p><p>"COVID is everybody's problem, and I think developing tools that can be used to help others is sort of why people go into health care," Dr. Cruzen said. "It was really consistent with our mission."</p><p>Open collaboration is something the world's governments and health systems should be striving for during the pandemic, said Michael Dowling, Northwell Health's president and CEO.</p><p>"Whenever you develop anything and somebody else gets it, they improve it and they continue to make it better," Dowling said. "As a country, we lack data. I believe very, very strongly that we should have been and should be now working with other countries, including China, including the European Union, including England and others to figure out how to develop a health surveillance system so you can anticipate way in advance when these things are going to occur."</p><p>In all, Northwell Health has treated more than 112,000 COVID patients. During the pandemic, Dowling said he's seen an outpouring of goodwill, collaboration, and sacrifice from the community and the tens of thousands of staff who work across Northwell.</p><p>"COVID has changed our perspective on everything—and not just those of us in health care, because it has disrupted everybody's life," Dowling said. "It has demonstrated the value of community, how we help one another."</p>
It's hard to stop looking back and forth between these faces and the busts they came from.
- A quarantine project gone wild produces the possibly realistic faces of ancient Roman rulers.
- A designer worked with a machine learning app to produce the images.
- It's impossible to know if they're accurate, but they sure look plausible.

The freemium online app intelligently generates new images from existing ones and can combine multiple images into…well, who knows. It's addictive — people have so far used it to generate nearly 72.7 million images, says the site — and it's easy to see how Voshart fell down the rabbit hole.</p><p>The Roman emperor project began with Voshart feeding Artbreeder images of 800 busts. Obviously, not all busts have weathered the centuries equally. Voshart told <a href="https://www.livescience.com/ai-roman-emperor-portraits.html" target="_blank" rel="noopener noreferrer">Live Science</a>, "There is a rule of thumb in computer programming called 'garbage in garbage out,' and it applies to Artbreeder. A well-lit, well-sculpted bust with little damage and standard face features is going to be quite easy to get a result." Fortunately, there were multiple busts for some of the emperors, and different angles of busts captured in different photographs.</p><p>For the renderings Artbreeder produced, each face required some 15-16 hours of additional input from Voshart, who was left to deduce/guess such details as hair and skin coloring, though in many cases, an individual's features suggested likely pigmentations. Voshart was also aided by written descriptions of some of the rulers.</p><p>There's no way to know for sure how frequently Voshart's guesses hit their marks. It is obviously the case, though, that his interpretations look incredibly plausible when you compare one of his emperors to the sculpture(s) from which it was derived.</p><p>For an in-depth description of Voshart's process, check out his posts on <a href="https://medium.com/@voshart/photoreal-roman-emperor-project-236be7f06c8f" target="_blank">Medium</a> or on his <a href="https://voshart.com/ROMAN-EMPEROR-PROJECT" target="_blank" rel="noopener noreferrer">website</a>.</p><p>It's fascinating to feel like you're face-to-face with these ancient and sometimes notorious figures.

Credit: NASA and NOAA<p>For <a href="https://data.giss.nasa.gov/gistemp/" target="_blank">its 2020 analysis</a>, NASA gathered surface temperature measurements from more than 26,000 weather stations. This data was incorporated with data from satellites as well as sea-surface temperatures taken from ship and buoy instruments. Once tallied, NASA's data showed 2020 barely edged out 2016 as the warmest year on record, with average global temperatures 1.02°C (1.84°F) above the baseline mean (1951-1980).</p><p>In a separate analysis of the raw data, NOAA found 2020 to be slightly cooler than 2016. This distinction is the result of the different methodologies used in each—for example, NOAA uses a different baseline period (1901–2000) and does not infer temperatures in polar regions lacking observations. Together, these analyses put 2020 in a statistical dead heat with the sweltering 2016 and demonstrate the global-warming trend of the past four decades.</p><p>"The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend," <a href="http://email.prnewswire.com/ls/click?upn=OXp-2BEvHp8OzhyU1j9bSWuwMvMWelqIco5RbfBrouY-2BQCsSv6FnrhBjR9xReGqV57KGOs0rVc5GKMmgs-2FJKbOzjb0sJ6yjzUvrv2w75ulYk3EUck8pSjkzYhoy5ADXO0eOcn7LDjqsHyK2gp2NRf2UysMK-2F9SN4oYUmRylQcRtSUo6-2FcYeK-2B9naUetByXNCR2gF8u_FU3lc-2FvIcVOtjb4iEuBVjFYoW0IRF5dtM-2FDfzzkhmYHO5IVgq387-2BxdHEMunBZ1-2Fy0-2BJDgXnZEYvN604G1TWJfy4M4HKnIouyasgRyWEHIYmPTiDXeFrd9FqRmsl0JQfksEElkp2ITvgyFkkivWV3GiFH7z7tl1cTZ2rNh2c-2FbCRKQxkH4-2BChgYT6uWeYOvXusiC4cDsZkEBvw7lOEdPsPq78JT8F5x5gc5cMRaRJY-2FZ8q8peaKsS7Mfc5OQ6yjyEU5YUHR4QKJ1Fn-2FDuwJ5jk4Gm28sxJZNXX9IEO-2FOHlhyRcJbl6rMWcoeJZDEd-2BM8UJ5ZY-2FYqc1DHevd1Mz-2B1fQ-3D-3D" target="_blank">Gavin Schmidt</a>, director of the NASA Goddard Institute for Space Studies, <a href="https://www.sciencedaily.com/releases/2021/01/210115103020.htm" target="_blank" rel="noopener noreferrer">said in a release</a>.

"In May, some places were 18°F above the average. There was a town in Siberia […] that reported a high temperature of 104°F. If that gets verified by the World Metrological Organization, it will the first there's been a weather station in the Arctic with a temperature above 100°F."</p><p>The Arctic is warming at three times the global mean, thanks to <a href="https://nsidc.org/cryosphere/arctic-meteorology/climate_change.html#:~:text=Over%20the%20past%2030%20years,climate%20change%20in%20the%20Arctic." target="_blank">a phenomenon known as Arctic Amplification</a>. As the Arctic warms, it loses its sea ice, and this creates a feedback loop. The more Arctic sea ice loss, the more heat introduced into the oceans; the more heat introduced, the more sea ice loss. And the longer this trend continues, the more devastating the effects.</p><p>For example, since the 1980s, there's been a 50 percent decline in sea ice, and this loss has exposed more of the ocean to the sun's rays. That energy then gets trapped in the ocean as heat. As the <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content" target="_blank" rel="noopener noreferrer">ocean heat content</a> rises, it threatens rising sea levels and the sustainability of natural ecosystems. In 2020 alone, 255 zeta joules of heat above the baseline were introduced into Earth's oceans.

They make for an eye-catching headline, sure. But those headlines can sometimes mask the fact that these years are part of decade-long trends, trends providing a preview of what a climate-changed world will be like. </p><p>And in case there was any question as to whether these trends were the result of natural processes or man-made conditions, Schmidt and Vose did not mince words. </p><p>As Schmidt said in the briefing: "Many, many things have caused the climate to change in the past: asteroids, wobbles in the Earth's orbit, moving continents. But when we look at the 20<sup>th</sup> century, we can see very clearly what has been happening. We know the continents have not moved very much, we know the orbit has not changed very much, we know when there were volcanoes, we know what the sun is doing, and we know what we've been doing."</p><p>He continued, "When we do an attribution by driver of climate change over the 20<sup>th</sup> century, what we find is that the overwhelming cause of the warming is the increase of greenhouse gases. When you add in all of the things humans have done, all of the trends over this period are attributable to human activity."</p><p>The data are in; the consensus is in.
