“Fully 15 percent of what comes in the door in Charlestown is not recyclable there.” The best thing you can do is learn what your recycling facility accepts — and doesn’t. But if you’re too busy to read up, here’s a guide that works pretty well at most US facilities… 🧵

Trump does plenty of the former. Putin does none of the latter. Both are despicable, neither are weak. I get that Adam is advocating for a leadership style he admires, but i don’t think it has so much to do with strength.

Well this seems like a cool job.

Like Olivia, I would look down upon HRW if it accepted Ansari's donations. This is an example of higher-order punishment, which is critical for supporting norms. Notice: we have this intuition even though we know the world would be a better place if Saudi money is in HRW's account than in Ansari's.

Another norm supporting our democracy has fallen. “Whatever threshold gets set here is the new floor for future prosecutions when roles are reversed,” Senator Thom Tillis of North Carolina told a CNN reporter. “That’s just the way this town works.” www.nytimes.com/live/2025/10...

Bet there’s a link with curly hair, too. And study of the Talmud. And eating cholent on weekends.

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on. Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts. 1/

This isn’t (yet) a clear example of a norm unraveling, since it’s the same guy violating the norm multiple times. But future governments will have to proactively right this ship, or the norm will be violated again — and the president will effectively be immune from investigation.

There is no law that prevents the president from firing the head of the BLS if they don’t like BLS’s numbers. Just a norm. Now there is neither a law nor a norm.

Three observations: 1. The Roberts Court position on presidential immunity seems slightly less crazy today. 2. It's hard to prevent law enforcement from being abused in such ways, and sucks that Rs let existing norms collapse. 3. Tulsi looks like RFK Jr. www.nytimes.com/2025/07/23/u...

'Unraveling' of a norm, in real-time.

The replication crisis is a great, recent example of norms changing -- and that change resulting in better social outcomes.

The golden rule of spin: if you have nothing good to say, say nothing at all.

These sorts of 'beachhead' violations of a norm (don't violate due process) are the sorts of things that cause the norm to unravel. I hope the norm holds, but IMO, this is *very* dangerous.

Question for legal scholars: As someone who once worked for an independent agency, I appreciate the value that their independence provides. If SCOTUS decides that independent agencies are unconstitutional, what are alternatives for ensuring a more stable, apolitical civil service?

A friend is wrapping their PhD at Harvard. They have a job lined up, but planned to defend and walk in a few months. Following today’s announcement, their advisor moved the defense. To tomorrow. That is how it’s done.

Incredible that which team of men-who-run-around-in-circles you root for says something about you and your values.

Garber’s got the gift of gab

This is the most sensible explanation for Trump’s tariffs that I’ve seen. He may also have some quaint ideas about how tariffs are good for society. But if they didn’t bolster executive power we wouldn’t have them.

One of the things that makes me particularly skeptical of DOGE’s stated aims is that government efficiency is much less about the number of employees and much more about the number of regulations. For a timely example, see: open.substack.com/pub/persuasi...

New ep! I talk to @erezyoeli.bsky.social about how game theory underpins our societies: strategyaaron.substack.com/p/a-beautifu...

A part of the culture war people don’t talk enough about: whether society should place expectations on individuals to behave in ways that are beneficial for others. Anti-woke anti-vaccine anti-foreign-aid is in large part just anti-helping-others.

USAID had a program that… identified and promoted its most efficient programs. It was run by one of the world’s foremost experts on evaluating foreign aid programs, Dean Karlan. He just quit. Folks, this isn’t about efficiency.

Once you enter the punishment phase of a subgame perfect strategy, then the aim is to inflict sufficient harm to deter future transgressions. That’s it. That’s what all these commentaries miss.

Hey #AcademicSky, what are examples of good scholarship on building a sense of belonging in the workplace? I'm looking to expand and diversify the material I have... any suggestions? That includes your own work! Cite yourself, please.

Emic justifications for 'don't transgress against a norm even when the harm is de minimus': www.nytimes.com/2025/01/15/m... Etic explanation: norms can't condition on continuous variables (how much harm), but can on categorical ones (did the transgression occur). papers.ssrn.com/sol3/papers....

Dad’s a pilot. Both grandfathers were pilots. Uncle, cousin, and brother… pilots. Can confirm.

Norms are categorical. If you permit small transgressions, you’re permitting large ones. papers.ssrn.com/sol3/papers....

Jill Jordan and @dgrand.bsky.social have a nice one-ed on this very topic: www.nytimes.com/2019/03/30/o...

This NYT article lists guar and xantham gum as indicators that a food may be ultra-processed. While this may be true, my understanding is that guar and xantham are not, themselves, ultra-processed or otherwise bad for you. Am I wrong about this? www.nytimes.com/2025/01/08/w...

Katherine Zarrella argues, in today's Times, that price increases of luxury products reflect not only increased demand, but an incentive to 'price out' some consumers. Implicitly, this analysis uses the logic of costly signaling. 🧵 www.nytimes.com/2024/12/19/o...
