recent Axios story on maternal health policy referenced
"findings" that a majority of people trusted their doctors and nurses. On the surface, there's nothing unusual about that. What wasn't originally mentioned, however, was that these findings were made up.
Clicking through the links revealed (as did a subsequent editor's note and clarification by Axios) that the public opinion poll was a computer simulation run by the artificial intelligence start-up Aaru. No people were involved in the creation of these opinions.
The practice Aaru used is called silicon sampling, and it's suddenly everywhere. The idea behind silicon sampling is simple and tantalizing. Because large language models can generate responses that emulate human answers, polling companies see an opportunity to use A.I. agents to simulate survey responses at a small fraction of the cost and time required for traditional polling.

As I’ve said a million times, I’m not particularly against smart uses of AI

This is the stupidest use I’ve seen yet though

Moral Economics: Al Roth and Ray Fisman at Cambridge Public Library, Monday May 11

Some of my Boston/Cambridge friends asked how to get tickets now because they're afraid it will sell out (the price is right), and others because they're afraid that if they don't come Ray and I will be speaking to an empty hall...

The machines are fine. I'm worried about us. On AI agents, grunt work, and the part of science that isn't replaceable.

Two thoughtful essays about the impact of LLMs on graduate education:

From personal experience I think the self-control problem mentioned in the first essay is very real.

And all I will continue to say is…imagine the worst, and be ready to defeat it. Is Trump gonna fuck with/try to cancel the midterms? Believe it, defeat it. Will Trump try to run for a 3rd term? Believe it, defeat it. We didn’t imagine the worst after the 2020 election, and Jan 6 happened. Not again.

Trump Lawyer Rebuked at ABA for Saying DOJ in a ‘Better Place’ A typically collegial white collar legal conference turned testy when one of the president’s defense attorneys faced incredulous and at one point rancorous pushback for praising Trump’s Justice Depart...

"'I wanted to thank Mr. Lauro for admitting the emperor has no clothes—the rule of law is dead because the people in this room and the Department of Justice pissed off President Trump,' … said @mitchellepner.bsky.social, a former federal prosecutor ….

“The Last Republican” — now free to watch on YouTube.

“A compelling portrait of political courage in an era when courage is in short supply.”

“It’s less a political documentary than a study of the personal cost of telling the truth in modern politics.”

50th Anniversary of Mathematics of Operations Research (and 50 papers, one for each year)

The 1981 paper is Roger Myerson's famous paper on auctions.

My 1982 paper had earlier been rejected by the JPE,with a letter from the editor, George Stigler, saying that the only economics in the paper was in the title.

Opinion | Is This the Most Important Supreme Court Case of the Century?

If we keep electing men like Trump, they will keep undermining that foundation, until it finally collapses.

One day that may well happen. But on Friday, the Supreme Court said not this day. On this day the presidency is stuffed back into its box. On this day the Constitution holds.
