during world war 2 the Germans had a maneuver that would cause you to black out
putting pressure on the artery on the side of the neck
I think you’re confusing Nazis with Vulcans.
Welcome to the SDMB, jojopeewee. Which column is this in reference to? Can you post the link? It would be helpful in order for others to comment on the article.
Is it related to this column on “Ninja death grips”?
This might be a judo choke, where pressure on the carotid sinuses and vagus nerve causes black out. That predates WWII by quite a bit.
The study mentioned in the article seems a little weak for a Cecil cite. Did the volunteers know the result of the alleged kyusho strike was supposed to be a knockout? For a valid test, the subjects should be completely unaware of the expectations of the strikers, and thus eliminate suggestion as a cause.

That’s what it sounds like to me.
Choke holds are used by the military and the police to subdue people. Knock them out, not necessarily kill them. The police are a bit nervous about them. Hence the case of Eric Garner:
There are two ways to choke out - an air choke and a blood choke.
Air choke is cutting off the windpipe. In order to do so, it requires traumatic obstruction - crushing the trachea.
Blood chokes cut off the blood supply to the brain. They can be done non-traumatically. However, you do need to limit the length of time you hold the choke.
From the picture on the Eric Garner wikipedia page, it appears Officer Pantaleo did not apply a proper blood choke. His elbow is not directly below the chin. That places part of the forearm across the trachea.
The medical examiner’s report shows there was no damage to the windpipe or neck bones. However, Eric Garner suffered from asthma. He was jumped on, held down, and then left lying face down on the pavement. After he passed out, he was rolled onto his side. He was still breathing on his own, so CPR was not performed. He suffered a heart attack in the ambulance on the way to the hospital.
It appears that his asthma was triggered by being grabbed and held down, possibly exacerbated by positional asphyxia - lying on his chest making breathing more difficult. He also had heart disease, contributing to the heart attack.
