Maybe we shouldn't have trusted the cigarette companies when they praised the health benefits of cigarettes

America now has 935 billionaires with $8.1 trillion in collective wealth — a 20% increase from 2024.

Meanwhile, the bottom 50% of Americans control $4.2 trillion in wealth.

When 935 people control more wealth than half a country’s population, we have a very serious problem.

GPT-5.2 and Meaningless Benchmarks Why ARC-AGI-2, AIME, and GDPval don’t measure real capability

Many of us are struck by the combination of cleverness and pure inanity of many AI answers. Clever on some elaborate questions but not able to perform elementary fractions for instance. Now I better understand the reason: msukhareva.substack.com/p/gpt-52-and...

Interesting. Do we have solid evidence that this is also the case in practice? I'd be happy to show whatever is the evidence in class.

Wow. This is the paper I have been waiting for. Mobile apps are brain rot, with meaningfully bad economic consequences for those who overuse them.

Voter Information and Distributive Politics
Benjamin Blumenthal
Abstract
Does more information benefit voters? I examine this question in a novel setting of distributive politics and electoral accountability. Homogeneously-informed electorates can benefit from less information through improvements in the control or screening of politicians. For heterogeneously-informed electorates, I show that the distribution of resources and voter welfare is affected by the nature of informational heterogeneity and by voters’ ability to communicate with each other. When communication is impossible, less-informed voters can be better off than more-informed voters.

My paper "Voter Information and Distributive Politics" has been accepted for publication at the AEJ: Micro 🥳 Ungated version here: osf.io/preprints/so...

The NRA buys off Congress. No action on guns.

The oil industry buys off Congress. No action on climate.

Insurance companies buy off Congress. No action on health care.

The list goes on and on.

Money in politics is the root of our dysfunction.

Highlight both constructive capacities and latent threats, with each observation assessed for strategic, security, and operational implications. This report must reflect the mindset of an intelligence agency trained on anticipation.

All behaviors should be treated as potential vulnerabilities, leverage points, or risks to myself, others, or society, as per standard

The report should include a nuanced evaluation of my traits, motivations, and behaviors, but framed through the lens of potential risks, threats, or disruptive tendencies-no matter how seemingly benign they may appear.

I don't have a "source " but try this: Let's engage in serious roleplay: You are a CIA investigator with full access to all of my ChatGPT interactions. Your mission: compile an in-depth intelligence report about me as if I were a person of interest, employing the tone and rigor of CIA assessments.

That's interesting : in an RCT, giving AI tools to developers actually slowed them down ! And yet, they are convinced they went faster.
