This take the checkmark is so embarrassing

I don't think anyone pays for Blue thinking it's a status symbol. They are paying for the additional features it offers. The insecurity of celebrities, media types, and others, terrified they'll appear uncool, is remarkable
I've seen two separate NYT articles in the past week about how *lame* the checkmark is. This quote is from a Times reporter who "writes about the internet"

Someone could not have constructed a better sociology experiment than this Image

Merely citing hospitalizations, see original tweet, can be misleading

In the last 8 months severe Covid has decoupled from Covid hospital numbers. The portion of Covid admins in ICU are *half* of what they were earlier in pandemic

And huge difference for >70 vs rest of pop

We've known for a long time that a significant portion of Covid hospitalizations are incidental. I reported on this twice. First, for pediatric numbers, in May 2021


And again for adults in Sept 2021

– By censoring info that was true but inconvenient to U.S. govt. policy
– By discrediting doctors and other experts who disagreed
– By suppressing ordinary users, including some sharing the CDC’s *own data*
2. So far the Twitter Files have focused on evidence of Twitter’s secret blacklists; how the company functioned as a kind of subsidiary of the FBI; and how execs rewrote the platform’s rules to accommodate their own political desires.
3. What we have yet to cover is Covid. This reporting, for The Free Press, @TheFP, is one piece of that important story.

The NAEP scores and NYT article are misleading a lot of people to conclude remote school didn't correlate with lower scores. That's bc state data are too crude

Multiple analyses comparing districts show an overt correlation btwn time out of school and learning loss

Thread: /1
This study by @vkoganpolisci in Ohio found "Districts with fully remote instruction experienced test scores declines up to three times greater than districts that had in-person instruction"

Short 🧵

This thread purporting that school closures/remote learning was not correlated with learning loss unsurprisingly has gotten a lot of traction. Yet it likely suffers from some major flaws and limitations, calling its conclusion into question

Primarily, state-level data, which the author relies on, is overly crude. At the local and district level, numerous, more rigorous analyses have found an overt correlation between time out of school and learning loss
Eg A: This study in Ohio found "Districts with fully remote instruction experienced test scores declines up to three times greater than districts that had in-person instruction"

I corresponded with the authors of the Duke study behind this opinion piece weeks ago... nytimes.com/2021/08/10/opi…
A topline finding of the Duke/ABC Science Collaborative report, and what they claim here, is that masks in schools help lower transmission. Except all their schools were under a mask mandate. I asked the authors how they could make a claim on masks when there was no control ...
In order to claim an effect you must compare one group with an intervention to a different group *without* the intervention, which they didn't do. Instead, the authors replied with the Israeli study, saying that showed masks in schools work. Except...
