Stories like this pop up often here. My take: this happens when the author is not making it clear what the advancement is relative to their own past work
It’s not reviewers being stupid. At best it’s bad writing. At worst it’s authors obfuscating to make the contribution seem bigger than it is

I was forced, finally, to use MS Teams. I still don't understand what it does. Seems superfluous. Idk what I'm supposed to do with it.

I just created a series of seven deep-dive videos about AI, which I've posted to youtube and now here. 😊
Targeted to laypeople, they explore how LLMs work, what they can do, and what impacts they have on learning, well-being, disinformation, the workplace, the economy, and the environment.

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding.
RegCheck was built to help make this process easier.

Event-study plots in DiD are incredibly persuasive—but, honestly, not always honest.
Why?
If parallel trends or no anticipation fail, DiD estimates are biased. Testing against a zero-effect null then becomes misleading.

Germany’s far right loosens its embrace of Trump
As public opinion in the country increasingly turns against the U.S. president over his threats to seize Greenland, the AfD is seeing the downside of its strong alignment with him.

Monday: Schools are remotely today, which means here is a pdf of what your child should do with your supervision.
Tuesday: Here is the list of upcoming daycare closures.

What ICE/BP is doing to Minneapolis is awful.
And it's taking everything they have. By population, Minneapolis is America's 45th largest city.
Keep both in mind at once: the regime's desire for authoritarian domination is bottomless, and they'll act on it, but their capacity to do so is limited.
