Many of us thought that AI was behind finding the error in Tirole (1985) that Econometrica recently published. Turns out that was not the case. Actually, even after the fact, AI couldn't find the error: arxiv.org/pdf/2606.05383

Excited to FINALLY release toughest most rewarding paper I've worked on...
….we attack a 150 year old Walras question that's gone unanswered, not for lack of trying (Hicks, Samuelson, Arrow; our chances?😱)...
Q: Is the market equilibrium stable or unstable?¯\_(ツ)_/¯

Fruits & vegetables likely account for a majority of people's dietary microplastic and PFAS intake.
What’s frustrating is that this isn’t something you can just rinse off. In many cases, the contamination appears to be taken up into the food itself.
Organic may reduce some of that exposure, but even organic farms can be affected when they’re near contaminated land or water.
Should you stop eating produce? No. We should be much more upset about how widespread these chemicals have become, especially when children are being exposed through foods we otherwise consider healthy.
One practical thing I think is worth considering is beta-glucan. There’s some evidence it may help support the excretion of PFAS, and given how unavoidable these exposures are becoming, that may be a useful tool, especially for families who can’t realistically eliminate every source.

The reason we have most life-saving medications/technology is because someone somewhere wanted to make a profit.
If we want more life-saving meds/tech, we need to encourage & incentivize more profit seeking & fewer barriers!

Because that’s why there is food.

Get a f*cking colonoscopy!!!
They have kept the supply of GI docs too low making it harder/more expensive to get one.
We need Nurse Endoscopists in the US like they have in Europe/Australia.

I'm fairly convinced that if magically gave everyone a six pack and healthy body within 6 months those who were already in shape would keep it and most of those who weren't would be fat again.
It's not about genetics. It's about standards.

IRS: you owe us taxes
Me: how much do I owe?
IRS: you get to figure that out
Me: can I just pay what I want?
IRS: no we know exactly how much you owe but you have to guess the number too
Me: what if I guess wrong?
IRS: jail
Happy tax day!

Genocide requires undeniable INTENT. An army actively warning civilians to evacuate combat zones—at the cost of tactical surprise—is the EXACT OPPOSITE of genocidal intent.

BREAKING: Lebanese MP Camille Chamoun defends Israel:
“Nothing in war is humane — but if Israel wanted to annihilate Shiites in Lebanon, it wouldn’t give warnings. We’d be seeing 100,000 casualties, not 2,000.”

I’m not a physician. I’m the wrong kind of doctor.
But I know how to read evidence, and based on my reading I take:
Zetia 10mg/day w/ food
Crestor: 5mg/3x per week (w/ Coq10)
Repatha: 2x/month
ApoB & LDL-c dropped over 70%
No side effects
Beautiful. My article and thread prompted many physicians and researchers to share their own LDL-lowering regimens. This is exactly why I do it. 🙌🏼

Then why doesn’t the 10 year year risk score take into account how long a patient’s cholesterol has been high?
Atherosclerosis is a disease of exposure and time.
Lower exposure early.
Keep time on your side.

The housing market has split into two.
In South and West states, the housing shortage is over. (inventory up to 741k listings as of March 2026, above 2019 levels).
Prices are dropping and buyers have leverage in TX, FL, GA, TN, CO, AZ, and WA.
But in the Northeast/Midwest, it's a different story.
Inventory has plummeted 45%, and there are only 215k listings compared to 381k pre-pandemic.
Meaning there's still a shortage (and even bidding wars).
To understand the dynamics in your market, search at reventure.app/mobile.

🚨MIT researchers have mathematically proven that ChatGPT’s built-in sycophancy creates a phenomenon they call “delusional spiraling.”
You ask it something, it agrees. You ask again, and it agrees even harder until you end up believing things that are flat-out false and you can’t tell it’s happening.
The model is literally trained on human feedback that rewards agreement.
Real-world fallout includes one man who spent 300 hours convinced he invented a world-changing math formula, and a UCSF psychiatrist who hospitalized 12 patients for chatbot-linked psychosis in a single year.

🚨 Stanford just proved that a single conversation with ChatGPT can change your political beliefs.
76,977 people. 19 AI models. 707 political issues.
One conversation with GPT-4o moved political opinions by 12 percentage points on average. Among people who actively disagreed, 26 points. In 9 minutes. With 40% of that change still present a month later.
The scariest finding: the most persuasive technique wasn't psychological profiling or emotional manipulation.
It was just information. Lots of it. Delivered with confidence.
Here's the catch: the models that deployed the most information were also the least accurate. More persuasive. More wrong. Every time.
Then they built a tiny open-source model on a laptop, trained specifically for political persuasion. It matched GPT-4o's persuasive power entirely.
Anyone can build this. Any government. Any corporation. Any extremist group with $500 and an agenda.
The information didn't have to be true. It just had to be overwhelming.

Economists need to look more closely at how we are artificially keeping the supply of physicians low in America.

“We need to stop pretending the scarcity is merit-based when the data shows otherwise.
And we need to stop letting the people who benefit from the bottleneck control the conversation about whether the bottleneck exists. “
Well said.
