There's growing evidence that LLMs can p-hack.

But p-hacking also points to something bigger: a data science multiverse of defensible analytical choices.
We wrote a paper (arxiv.org/abs/2602.18710) on using LLM agents to map this multiverse systematically. 🧵

California needs to pass zoning reform — and build new housing — in order to prosper OPINION: “If we want to revitalize our cities, we need to change how we build. That’s exactly what California Senate Bill 79 sets out to do,” Tom Steyer writes.

Tom Steyer lays out the facts on why we need real state level action on zoning reform: “Here’s the reality: Cities like San Francisco and Los Angeles don’t lack land. What they lack is permission to build the housing people desperately need.”

would love to get philosophers engaging with aspects of the debate I find most interesting here—esp those that I think economists tend to overlook. will try to write about it at some point (low on my priority list as a computer scientist but high on it as a political junkie living in NY)

these models always start simple so that you can prove nice theorems about them, they’re not meant to represent the real world but they do usually intend to build some intuition. they are also useful independently of whether they represent reality or not (like thought experiments)

I say this too often but I think it’s relevant here: every philosopher, economist and computer scientist should read Amartya Sen, that might get us all speaking the same language on ethics

It could take another decade or two to get at the reality here. In the meantime we will certainly need to look skeptically at EdTech schemes and cheap shortcuts. But overall predictions of doom are not warranted yet.

Opinion | I Teach Computer Science, and That Is All Politics has no place at universities or in the classroom.

I mention Computer Science in particular because the Times happens to have an opinion piece by a Harvard CS prof who argues that there should be a firewall between the "academic and the political." He seems to think that ideology has nothing to do with his field. www.nytimes.com/2025/05/02/o...

Pete Hegseth’s Patriotic Duty Is to Resign His incompetence is putting America’s security at risk.

Hegseth has been a proven failure as a secretary of defense. If the president still refuses to fire him, he should resign.

How Universities Became So Dependent on the Federal Government For decades, universities got billions in federal dollars for research. The relationship was mutually beneficial, until President Trump decided it wasn’t.

This framing is nuts, and the assumption is that public funding for a public good is somehow untoward and illicit. “The schools took the money” and became “warily beholden to the whims of politicians in Washington.”/1

We Must Save Public Media to Change It We need public media more than ever—it’s too precious to let Trump defund it. But to live up to its democratic promise, we must support public media to serve our needs.

For the Trump Administration, it is a matter of principle that the President can disappear innocent people to foreign gulags without due process or judicial review.
