Stressing at the Airport? Just chill…ICE is on the way!

The Department of Homeland Security has been shut down for 36 days. This is the third funding lapse in six months. More than 400 TSA officers have quit since February 14. On March 14, 55 percent of scheduled staff didn’t show up at Houston Hobby. Airlines are warning of chaos through Easter. On Saturday, President … Read more

Dispatches from the Underground: March 20, 2026

A new recurring feature, starting this week. A few items from the news — sometimes updates to arguments this blog has already made, sometimes new events the existing framework illuminates without quite rising to a full post — followed by a couple of things we’re watching that haven’t ripened yet. Everything here is shorter than … Read more

Your Basket May Vary (or, “The Average Is Not Your Neighbor”)

Yesterday’s post argued that a national aggregate can accurately represent no one’s actual experience when the underlying data are structured the right way — or, more precisely, the wrong way. The incarceration example was instructive precisely because it was symmetrically uncomfortable: the same Simpson’s paradox that embarrasses the reform-is-working narrative also embarrasses the cities-are-dangerous one. … Read more

All Statistics Are Local

A friend and colleague gave a talk today about incarceration trends in the United States (she knows who she is, and I owe her a coffee). The importance of the problem — and the genuine messiness of the data — got me thinking about how difficult it is to convey the right lessons from debates … Read more

Honest and Effective (Or, “Montana Has a Type”)

On March 5, at 4:52 p.m. Mountain Time, Kurt Alme filed to run for the United States Senate in Montana. At 4:55 p.m., incumbent Senator Steve Daines withdrew from the same race. At 5:00 p.m., the filing deadline closed. At 5:02 p.m., Daines endorsed Alme. Jon Tester, Brian Schweitzer, Steve Bullock — none of them … Read more

Bam. (A Short Post. Seriously.)

Regular readers of this blog — yes, both of you — will know that I recently published a piece called “Can a Game Know Its Own Rules?” It was — and I say this as the person who wrote it — very long. I am told it has been read by dozens of people, some … Read more

What the Prince Doesn’t Know Can Still Get You Fired

Bismarck is credited with the observation that laws are like sausages: it is better not to see them being made. The remark is probably apocryphal, which is itself somehow on-brand for a quote about the virtues of not looking too closely at things. Either way, the folk wisdom it encodes is real and ancient: what … Read more

Why the Thing That Might Take Your Job Is So Nice To You

Let me tell you something you already know: ChatGPT, Claude, Grok — whatever flavor you’ve adopted — is very, very nice to you. Suspiciously nice. “Your presentation looks great, here are a few minor suggestions” nice. “That’s a fascinating question” nice. “I can see why you’d approach it that way” nice. You know this. You’ve … Read more

Can a Game Know Its Own Rules?

Hi again! The question I’m about to pose is one that, I’m reliably informed, clears rooms at cocktail parties. But I think it sits at the foundation of why institutions are so hard to reform — and why the people who try to reform them so often end up making things worse. That’s for next … Read more

The IRS Is Here to Help. So Is ICE.

It’s been almost ten years since I’ve written here. The last time I posted, Donald Trump had just clinched the GOP nomination, his Banzhaf power index had hit 1.0, and I was calculating the proportion of his campaign contributions that were unitemized.1 That was June 2016. I stopped writing because the general election demanded a … Read more
