The IATA chief said yesterday the crack spread (diff between processed fuels and crude from the refiner) had shot up from a normal 40% to 100%β€”so airlines are getting hit particularly hard.

Jim Cramer suggests on CNBC that Trump could β€œbomb Tehran into the Stone Age” until Iran reopens the strait, citing U.S. bombings of North Vietnam in the 1970s. Carl Quintanilla points out to him that Hanoi won that war.

Affirm all your great points, but jeebus, the faux social science-ness of focus groups was already terrible, now imagining anyone deducing anything from these bots. Coming to campaign near you.

Not only did team USA lose to Italy but now we have to do math, which is even worse.

A short guide to email opening lines β€œI hope you are well” and other classics

Good but misses the truly passive-aggressive US email openings:
"Just circling back on this." / "Bumping this to the top of your inbox." Ostensibly collegial. Actually: you ignored me, and now you know that I know.
The false promise of brevity: "Quick question:" Followed by four paragraphs.

In the criminal justice system, bread-based offenses are considered especially heinous. In France, the dedicated detectives who investigate these vicious felonies are members of an elite squad known as the Bread Busters. These are their stories.

People who were calm even during the roiling markets the Sunday/Monday after the tariffs last April are using a lot of exclamation points tonight.

I know they have their uses (increasingly so with AI) but the below is why I could never give oral exams: the cringe is just too much for me. (Good lord this kid had how long to prepare for this? And yet, he had immense power.)

Never thinking one step ahead: if American personnel face casualties while escorting many ships under, say, Chinese flags, how long is that going to work with the public?

Spotted that and thought the sameβ€”but then I got two paragraphs later about the injuries and thought, welp, the too-stupid-to-be-plausible has been very plausible a lot lately.

Where Trump's money comes from (and other mysteries) This week's newsletter covers a range of topics: The president's complex network of companies, how weather has gotten worse, a new tool to visualize the whole world at once. But I did reserve some tim...

Inspired by ProPublica’s new database, I created a visualization of the nearly 400 LLCs that make up Trump’s business empire.

(In the table above the top quartile group have 38.8% AI exposure; the table compares that group with those with 0% exposure.)

Table titled "Differences between high and low exposure workers," showing demographic, education, and labor market characteristics for two groups drawn from the Current Population Survey: workers with no AI exposure (n=42,546) and workers in the top quartile of AI exposure (n=32,301). High-exposure workers have 38.8% AI task coverage versus 0% for the unexposed group. High-exposure workers are more likely to be female (54.4% vs. 38.8%), white non-Hispanic (65.1% vs. 54.5%), and Asian non-Hispanic (9.1% vs. 4.7%), and less likely to be Hispanic (13.8% vs. 24.8%) or Black non-Hispanic (9.7% vs. 13.2%). Education levels differ sharply: high-exposure workers are far more likely to hold a bachelor's degree (37.1% vs. 13.3%) or graduate degree (17.4% vs. 4.5%), while low-exposure workers are more likely to have only a high school diploma (38.9% vs. 17.7%) or less than a high school education (13.2% vs. 2.3%). In labor market outcomes, high-exposure workers earn a higher average hourly wage ($32.69 vs. $22.23) and are less likely to be union members (5.3% vs. 11.7%).

Anthropic out with a study on jobs most affected by AI. (It hews close to BLS/Fed studies, so not a hype job.) cdn.sanity.io/files/4zrzov... This table compares two groups of workers before ChatGPT launched (Aug–Oct 2022) to show who is most at risk from AI displacement.

Chart showing in many countries, people see their fellow citizens as morally good.

Chart showing in many countries, people see their fellow citizens as morally good.

We asked people around the world to rate the morality and ethics of others in their country.

The U.S. is the only place we surveyed where more adults describe the morality and ethics of others living in the country as bad than good. See our full morality report here: www.pewresearch.org/...
