Why was this flagged?

Because enough people clicked the flag link. If enough of them click the flag link on this one, it'll get flagged too!

Flagging is there for stuff that's off-topic or generating low-quality discussion in the views of the people clicking the flag link. Sometimes the admins will step in to unflag the article if it looks like neither of these apply, and/or if it would be helpful to have a containment topic for discussion of a particularly popular contentious topic.

>That is why they're doing it. They're looking for pretexts to reduce headcount. They don't give a s* if the positive is false or not. At least we're still at the stage where they're bothering to find pretext. There is still hope.

Is there? They are already a few rungs up from illegal criminals. Not much further to get to anyone since these are approved visa holders. Im just waiting for them to declare all Californians as non-citizens at this point.

That would be doing Californians a favor tbh. Then we'd have an excuse to leave this rotten union.

Coastal Oregon and coastal Washington can come too.

The MRI analogy is not good. The false positive risk is only against the present-day distribution of MRIs mostly taken of symptomatic patients; if we had the dataset of "annual MRIs for everyone" we would very quickly recalibrate our sensitivity to the new baseline.

... yeah? You'd expect the false positive rate to be HIGHER when you're not looking at an enriched patient subset. That's why we're careful about recommending certain kinds of screening. See also: PSA screening.

Well, you missed my point. I'm not talking about "you look at the MRI and see something and say it's a positive", I'm referring to the process of reading MRIs as like a statistical model (even if in practice it exists in the minds of radiologists) which is trained on the corpus of MRI data. That model will depend in some way on the distribution of positive/negative examples in the corpus; if the corpus changes the model has to then be updated to match.

Point is, the false positive concern is only a concern if you use the old model with the new corpus. Don't do that! That's dumb!

The net effect of MRIing everyone on public health would likely be enormously positive as long as you don't do that.

MRIs produce shadows that are indistinguishable from cysts or tumors all the time. They are benign, but no amount of data will reduce them. And telling someone "you have a shadow here, it's probably benign" makes people anxious and they go, "maybe I should boost it?" Which is needlessly invasive.

huh, well, if it's true that "no amount of data will reduce them" then my point is wrong, but I highly doubt that's true.

Tautology isn't a useful reply to this question. At best it's a distraction, and at worst deflection. That people clicked the flagged link is already apparent by virtue of the post having been marked as flagged. That doesn't engage with why it was flagged.

I’m ready for it. Good luck to the rest of the country without our food and industry lol.

This won't happen in practice because it's incredibly impractical. It would require massive amounts of manpower and be very expensive.

Also visas expire, so why not simply implement better checks for new visas. Most of the 55M visas are probably fine, so you have to spend an exorbitant amount of resource on finding very few issues. It's much cheaper to add additional check to new visa applications.

55M is also just a crazy amount of visas for a country with 350M citizens. Especially given that I'd guess that a large amount of people travel to the US on a visa waive program.
