the researchers note that the sister raised in the US had suffered three previous concussions

+

the twin raised in Korea described growing up in a loving and harmonious family home, the adopted sister reported a harsher upbringing, colored by regular conflict and the divorce of her adoptive parents

It does seem as if there would be explanations for the unusual difference.

That's kind of an understatement. Three traumatic brain injuries is not exactly something that can be ignored when discussing differences in mental faculties.

Concussion, and Traumatic Brain Injury, are two very different diagnosis.
The two shouldn't be conflated.

All concussions are traumatic brain injuries, not all traumatic brain injuries are concussions.

And there's a reason for the two different terms. Concussions (or mild TBI), is a brief dysfunction of the brain. Full TBI is substantial often permanent damage.

Using the term TBI for concussion, is an example of manipulative intensifying language, to make something sound worse than it is.

Lol brain injury is cumulative (e.g. football players) in what way is calling brain injury what if is "manipulative intensifying language" lmao

This isnt me defending the US btw, apparently its the kind of place you get lots of concussions (the nice, non traumatic kind tho ;3)

If there are two correct and common terms; One broad that includes far more severe effects, and one narrow that specifically excludes the worst. Then choosing to use less accurate term is misleading and manipulative, intentionally or not.

I'm not conflating anything. A concussion is literally considered a mild TBI.

A concussion is a mild traumatic brain injury that affects brain function. Effects are often short term and can include headaches and trouble with concentration, memory, balance, mood and sleep.

https://www.mayoclinic.org/diseases-conditions/concussion/symptoms-causes/syc-20355594

Concussion is a type of mild TBI that may be considered a temporary injury to the brain but could take minutes to several months to heal.

https://www.ninds.nih.gov/health-information/disorders/traumatic-brain-injury-tbi

The Centers for Disease Control and Prevention (CDC) defines concussion as a traumatic brain injury (TBI) caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth.

There seems to be this trend of masochistic behavior in the US. Where we take pride in our injuries and illness, bragging about working and pushing ourselves while we are suffering. The whole time telling ourselves it’s not that bad. It’s definitely stood out more since Covid, it’s stupid behavior though.

Thank the puritans who evolved into evangelicals and baptists for that.

“Religious freedom” to make others suffer is why they came here. The idea for separation between church and state did not come out of nowhere.

That does exist.
Just like the tendency to make things sound worse than they are.

Why use the broader term instead of the more narrow, when both are accurate? Could it be in this case to associate a relatively minor injury with its most extreme version?

The same way that stapling your finger and being shot, are both wounds.

It can be ignored if your only priority is dunking on America. I feel sorry for this young person being made into the poster child for everyone who would like to take America down a peg. Even the concussions will somehow get attributed to “the way things are there.”

Right, this assertion is invalidated and agenda-driven.

It’s invalidated because multiple concussions would probably damage the brain and reasonably lower IQ. Also, the potential abuse that was hinted at would of course potentially affect IQ as well. It’s agenda-driven because it trivializes all of the above in order to push what seems to be an anti-USA agenda.
