The thing that’s most remarkable to me about these betting sites with respect to political issues is that anybody is willing to be a counterparty without also being an insider. Pure adverse selection.

Two categories of analysts who might take a step back, away from the microphone or keyboard, this weekend:

β€”Those who assured us that Trump was the real anti-war candidate.

β€”Those who assured us that invading Iraq was necessary and would work out great.

In Iran, air power alone will not reshape the regime. Since WWI, dozens of U.S., Israeli & allied air campaigns have tried to force political change β€” none installed friendly governments. None! They strengthen nationalism and intensify resistance.

Surely it’s the whales excreting it, which explains why they were so critically important to the ACK economy

Cocaine levels in Nantucket's wastewater are growing exponentially. No one is sure exactly why. After measuring 50% above national levels in September, the island saw even steeper increases later in the year.

It’s funny that there was a very popular movie made about this in the 80s. Except the premise was that AI would figure out that this was bad, actually

Working Paper 34866
DOI 10.3386/w34866
Issue Date February 2026
Modern smartphones present new threats to road safety beyond talking and texting, but the real-world effects are difficult to study. One way to causally assess the impact of smartphones on road safety is to identify arbitrarily timed events during which smartphone-related distraction may exogenously increase – i.e., a situation that relies not on plausibly random variation in who uses smartphones while driving, but when smartphones are used. We investigated the impact of smartphones on road safety by examining traffic fatalities on days when smartphone use likely surges: the release of major music albums. Using event study analysis, we show that music streaming – an indicator for smartphone use, where streaming most often occurs – sharply increases, by nearly 40%, on dates of major music album releases, while U.S. traffic fatalities increase by nearly 15% on those same days. Mobile device use while driving is a known safety issue, but today’s smartphones present new and greater opportunities for driver distraction. Our study indicates how features of these phones may have important impacts on distracted driving and traffic fatalities.

LLMs break our ability to conclude when there is proof of effort. We make high schoolers write essays and do math assignments not because we care about essay or because we don’t know the problem set answers, but because the effort trains them in a certain way. We read customized cover letters as an important signal of interest, because it has traditionally been hard to make a good one, and you could only do it for so many jobs you applied for. Gatekeeping is inevitable, and when the old mechanisms stop working, other measures will step in, like relying on the prestige of the candidate’s institution or their connections to decide who to hire, or what papers to cite or publish.

I think about this a lot with LLMs and education and also publishing. The hope that by undermining failing or unfair systems, LLMs will destroy the hierarchies and unfairness seems... naive. The result will likely be the opposite. jessicahullman.substack.com/p/zeynep-tuf...

US appeals court says law firm's size doesn't limit legal fees A federal appeals court on Tuesday ruled that a trial judge in California improperly slashed the hourly rates sought by a small law firm after it won an antitrust case, saying that a law firm’s size cannot be used to justify awarding lower fees.
