SCOOP: The State Dept has started asking career diplomats up for promotion if they voted for Trump in 16, 20, 24.
Federal law prohibits politically based hiring for career staff.
State tells @washingtonsun it's screening for "fidelity" and execution of the president's vision👇

On The Report Card, @natmalkus and @dcoxpolls discuss how technologies such as social media, AI, and location tracking are affecting teenagers; what gender relations are like among high school students; and how teens today think about family, religion, politics, and America. aei.org/podcast/american-ado…

President Putin is a murderer.
His soldiers use rape as a weapon.
He has launched wars costing thousands of lives.
His agents have stolen children and destroyed families.
Russia today is what President Reagan correctly called it: the evil empire.

Do high school sports help on discipline?
New AEI report with Sam Hollon. Varsity athletes are suspended at less than 1/2 (!) as often as nonstudents. In season (likely causal) athlete risk falls further.
46% lower out of season, 62% lower in season.

Are you an undergrad interested in @AEI's mission and want to learn from our scholars in seminar-style discussions? If so, apply to our Winter Honors Program, hosted in Charleston, SC, in Jan. 2027. More info at the link ⬇️ aei.org/whp/

$43B to paper over your predictable policy mistakes, plus another $30B in "emergency" aid and tens of billions more from the "usual" farm subsidies.
Insanity.

所谓优雅的数学结构，本质上是人类为了迁就自己那点可怜的脑容量，被迫发明出来的拐杖。
一个顶尖人类数学家的工作内存，撑死也就同时追踪五六个变量的交互。
当你在算一个偏微分方程或者组合不等式时，一旦展开到三阶以上，几十个交叉项涌出来，人脑就直接宕机了。
所以人类数学家极其厌恶展开高阶项，一旦看到高阶项发散，人类的本能反应是此路不通，赶紧退回来找对称性、找不变量、搞同调代数或者几何直观，试图不展开式子就把问题绕过去。
但 AI 没有这个生理缺陷。
对于上万个并发的 Agent 来说，同时追踪一万个五阶交叉项的系数变化，跟我们算 1+1 一样轻松。
在它的视野里，根本不需要什么几何直观，它直接站在高维的代数展开式里往下看，人类觉得像乱麻一样的百项高阶余项，在它眼里就是一张明明白白的线性方程组。
既然把式子硬展开到第七阶，再凑几个待定系数就能让所有讨厌的发散项精准归零，它为什么要费劲去帮你发明一个人类能看懂的新概念？
这 700 个结果背后最无奈的黑色幽默：我们终于拿到了上帝账本里的答案，却发现上帝算账根本不用微积分，他老人家是直接拿计算器硬按出来的。

Those working in the chronic absenteeism space have had few occasions to celebrate since the pandemic.
But, as @natmalkus writes in a new piece, "that might be changing" as "in many states, districts and schools are picking up the pace on absenteeism."

I am seeing hope in early returns on chronic absenteeism. My latest @AEIdeas.

Petraeus: Ukraine is killed and wounded 46,000 in the past month alone, while Russia recruits a little over 30,000.
When Starlink was completely shut down, Ukrainian front-line commanders texted me that they were losing control of their formations. 1/

President Trump is right to want peace between Ukraine and Russia. But his actions are making that harder to achieve by emboldening Putin's aggression.

With federal graduate student loan caps now law under OBBBA, universities can no longer rely on effectively unlimited Grad PLUS loans. How are grad schools responding?

This is a fun paper by @natmalkus and @SamHHollon on the benefit of high school sports. They find varsity athletes’ daily suspension risk was 46% lower out of season and 62% lower in season.
This is partly due to differences between athletes and nonathletes, of course. But the extra in-season drop is evidence that playing helps students stay out of trouble.

46% lower out of season, 62% lower in season.
By sport, football and wrestling have much higher rates, but still below nonathletes. Partly, but not all, because they are overwhelmingly boys.
Full paper below, & this is the third on high school sports. Huge thanks to Sam Hollon, @IHSAA1 & @EducateIN
