Fun fact that I just learned from some peak offseason content. Although I can practically see into Fenway from Lansdowne Station, there are 8 MLB stadiums closer to public transit

As an everything bagel enjoyer, I'm not sure I like everything bagel BLANK becoming such a popular and negative shorthand
This is a smart piece by @mtkonczal.bsky.social on why the Trump administration has stumbled over itself and failed so badly at consolidating power, despite its advantages: everything-bagel authoritarianism, or the inability to tell any part of its coalition "no."
Everything-Bagel Authoritarianism
If you want to dismantle a liberal, pluralist democracy, you need to be able to tell parts of your far-right coalition “no.”

Among other catastrophic effects of the resurgence of vaccine-preventable diseases, this new work shows how it drives student absences (and undoubtedly learning as well)
In 2000, measles was declared eradicated in the U.S. Today, declining child-vaccination rates are driving the largest measles resurgence we've seen in 3+ decades. How do these outbreaks impact schooling? @tomdee.bsky.social and I examine this question in West Texas, the country's largest outbreak.

Beware natural scientists doing social science
You wouldn't trust an economist doing physics or chemistry or astronomy. So don't trust the reverse
You wouldn't trust an economist doing physics or chemistry or astronomy. So don't trust the reverse
There is a growing problem of big name natural-science journals publishing social science that is "problematic".
This reflects a inability to accept the statistical standards and skills in social science are often much much higher than in many areas of the natural sciences.
