Brevity is an undervalued skill. It takes *work* to identify what is essential and to convey the key points clearly in limited words.

(Tweet/Skeet-type writing is actually great practice for this kind of work).

NYT headline: “Kennedy Advises New Parents to ‘Do Your Own Research’ on Vaccines” Subheader: “In an interview with Dr. Phil, the health secretary offered false information about vaccine oversight and revealed a lack of basic understanding of new drug approvals.”

“And I’m like, what do you mean, you ‘do your own research’? You running a double-blind study in your living room, dawg?”

Yes, good data visualisation is important. But "good data visualisation" is increasingly (wrongly) equated with "data visualisation that looks nice."

Good data visualisation is meaningful and interpretable.

Aesthetics are second order, and only matter if they contribute to the above.

Mahmoud Khalil’s Son Arrives After ICE Refuses to Let Him Attend Birth Mr. Khalil, a permanent resident detained in Louisiana, had requested a monitored furlough for the birth. His request was denied in less than an hour.

The Department of Homeland Security denied Mahmoud Khalil permission to attend the birth of his first child, who was delivered at a New York hospital on Monday, according to emails reviewed by The New York Times.

The Kleptocracy Presidency Under Trump, conflicts of interest are just part of the system.

"We are living through a revolutionary change," @anneapplebaum.bsky.social writes of the Trump era. "For the past decade, American government and business alike have slowly begun to adopt the kleptocratic model pioneered by countries such as Russia and China."

Netflix makes disrespectful Austen adaptations and I didn't spend all my youth becoming a basic girl who defines herself by loving Pride and Prejudice to squander that by watching this mess

City Contracts Director Resigns Suddenly, Latest Adams Appointee to Bow Out Lisa Flores was one of Eric Adams’ first appointments, in charge of tens of billions of dollars of business with nonprofits and private vendors.

NEW: City Contracts Director Resigns Suddenly, Latest Adams Appointee to Bow Out

Since 1979, the U.S. Department of Education has spent over $3 trillion with virtually nothing to show for it. Despite per-pupil spending having increased by more than 245% over that period, there has been virtually no measurable improvement in student achievement: Math and reading scores for 13-year-olds are at the lowest level in decades. Six-in-ten fourth graders and nearly three-quarters of eighth graders are not proficient in math. Seven-in-ten fourth and eighth graders are not proficient in reading, while 40% of fourth grade students don’t even meet basic reading levels. Standardized test scores have remained flat for decades. U.S. students rank 28 out of 37 OECD member countries in math. President Donald J. Trump and his administration believe we can, and must, be better. Instead of maintaining the status quo that is failing American students, the Trump Administration’s bold plan will return education where it belongs — with individual states, which are best positioned to administer effective programs and services that benefit their own unique populations and needs. Instead of a bloated federal system that burdens schools with regulations and paperwork, the Trump Administration believes states should be empowered to expand educational freedom and opportunity for all families. Why would we keep doing the same thing over and over again and expect a different result?

Two noteworthy things about the White House press release ahead of today's announcement regarding ED:

(1) It's all about K-12, while most federal money goes to higher ed.
(2) Most of the links are to NCES reports...and NCES is now down to about three employees.

‘I Want to Stand Up for Higher Ed’: Protesters Rally Against Education Dept. Cuts As demonstrators gathered in Washington, D.C., researchers met across town to discuss the toll that drastic reductions at the agency would have on their work.

"[Baker] began her [chair comments] by acknowledging that the US 'no longer has an effective federal apparatus for education policy' and discussed how a diminished department will affect the policy implications outlined in the papers presented at her session."

NH’s new ID requirements send some would-be voters home to grab passports, birth certificates The law requires all new voters to show proof of their U.S. citizenship. For some, that meant making multiple trips to and from the polls before finally casting a ballot on Tuesday.

As predicted, women in New Hampshire had a hard time voting yesterday because of the new proof of citizenship law:

“It doesn’t have my married name on it,” she said. Town voting officials then sent her away a second time, to get her marriage certificate.

👀🚨Sarah Chung, Jing Liu and I have a new NBER WP! We use daily wind direction as an instrument for air pollution, paired with daily data from a large school district in CA to estimate the effects of daily air pollution on students and teachers. 1/ www.nber.org/papers/w33549

"These results suggest, for both NYC and all school districts, that while school infrastructure investment matters for student outcomes, how this funding is targeted is key."

The usual suspects are out there yelling "There are 23 million government workers! Fire most of them!" No awareness that most work for local governments, and most of *them* are schoolteachers. Federal employment hasn't grown since the 1950s

Really cool work showing how increased interracial contact in childhood (in US schools) impacts long-run racial attitudes!
- Whites exposed to more Black peers in school end up living in areas with more Blacks in adulthood.
