The OECD was the audience we had in mind when we wrote this paper. Its reports are among the most influential in shaping education policy around the world. There is no better place to discuss what the evidence says on whether students benefit from same-sex teachers .

"genAI" doens't "learn" (tech execs' term) since it has no brains. Instead, it stores and regurgitates - PLAGIARISM.... "many AI developers use a more technically accurate term when talking about these models: lossy compression."

What I’d like to know @nytimes.com is how to boycott these companies. Effectually i would to see a table of the services or products made by these sometimes obscure companies, so we can prefer competitors with values we can get behind.

Can’t believe European leaders are discussing legality of US invasion of Venezuela. A summary of US actions in Venezuela: Kidnapping a citizen in their own country Expropriating their natural resources Seizing power until somebody deemed adequate is found. Who is next: Canada, Greenland?

Entshittification — today we’ve had it with Netflix. Now we can’t even use Chromecast. This blogpost sums it up. « Netflix - like Airbnb, Uber, and the rest of the share economy from the 2010s - just isn't what it used to be anymore. » www.whistleout.com.au/PayTV/News/w...

We’re all thinking it, Netflix sort of sucks now

Netflix won the streaming wars but we're still reeling from the fallout.

Totally!! Check out the video from his BBC Proms 2015 concert and his 2024 concert at the Philharmonie de Paris, both are out of this world!! In the 2024 concert he uses a weird sort of glass instrument at the beginning, fascinating

Holy shit. So Elon decides it would be nice to know what region of the world people are posting from. So they add that little feature. 2 hours later they figure out that many Trump supporters with millions of followers are posting from other countries. Surprise! That "feature" is now gone.

CSWEP strongly condemns Larry Summers’ behavior as revealed in the email correspondence with the late Jeffrey Epstein. While abuse of power in the economics profession is not new, rarely has the intent behind such abuse been so clearly stated.

À really interesting short study — based on a survey in the US, the public supports Unis championing initiatives (environmental, DEI, free speech, …) beyond research & ed, but finds political engagement inappropriate. Women & liberals support DEI initiatives but men & conservatives do not.

« The era when American politics could make or break global climate co-operation is over. The world is no longer waiting for Washington. This time the global south is leading the way. » — a great piece by an architect of the Paris agreement @economist.com economist.com/by-invitatio...

The climate action that matters is in the global south, argues an architect of the Paris agreement

But, writes Christiana Figueres, innovation still has to outpace climate impacts

Yes I agree! Hallucinate makes it sound like LLMs think and make mistakes, but that’s not hat it is.

Researcher at OpenAI studied why LLMs hallucinate: it’s a fundamental feature of the approach, it’s not an engineering glitch that will be solved with more money or data.

Evidence from random roommate assignment and a gaming ban for minors in China once again show what I now believe incredibly strongly: smartphones and social media destroy civilization via @arpitrage.bsky.social

Abstract
Concerns about excessive mobile phone use among youth are mounting. We present estimates of both behavioral and contextual peer effects, along with comprehensive evidence on how students' own and their peers' app usage affect academic performance, physical health, and labor market outcomes. Our analysis draws on administrative data from a Chinese university covering three student cohorts over four years. We exploit random roommate assignments, differential exposure to a policy shock (gaming restrictions for minors), and differential exposure to a discrete event (the introduction of a blockbuster video game) for identification. App usage is contagious: a one s.d. increase in roommates' in-college app usage raises own usage by 5.8%. High app usage is harmful across all measured outcomes. A one s.d. increase in app usage reduces GPAs by 36.2% of a within-cohort-major s.d. and lowers wages by 2.3%. Roommates' app usage reduces a student's GPAs and wages through both disruptions and behavioral spillovers, generating a total negative effect that exceeds half the magnitude of the impact from the student's own app usage. Extending China's three-hour-per-week gaming restriction for minors to college students would boost their initial wages by 0.9%. High-frequency GPS and app usage data show that heavy app users spend less time in study halls, are more frequently late or absent from class, and get less sleep.
