Dunning-Kruger effect in practice:
In 53k forecasts across 100 projects, people who are more confident are actually much less accurate.

Few things I love more than when I see a paper report on how research was put to use at scale!!👇
New study on fixing college admissions. In Chile’s centralized system, personalized, in-platform info helped students avoid common app mistakes & improved outcomes🧵⬇️

First Father’s Day as a new dad—and I’m still in awe. In the early 90s I doubted I’d ever see marriage, fatherhood, family. Yet here we are: two husbands, one *amazing* son, and a world that has made progress possible. So grateful! 🥰🥰

RegLab developed a scalable solution to use AI-based research assistant ("STARA") to crawl 10's of millions of words in federal/local legal codes & identify reporting requirements. Many of these are outdated. The SF City attorney wants to cut 1/3rd of them dho.stanford.edu/wp-content/u...

This isn't just a problem in SF though. The @WashingtonPost.com described the explosion of mandated reports as a congressional “black hole” with reports that can consume months of staff time w/ only a subset informing policy, legislators or the public www.washingtonpost.com/sf/national/...

As @ezraklein.bsky.social notes, “We’ve allowed an administrative state to accumulate like barnacles on a ship around the executive branch.” You might call this "policy sludge"

The improvements have already spread to 500+ kilns in Bangladesh
Now is the time to accelerate this work to tens of thousands of other kilns that could benefit across South Asia
It’s a rare best buy for climate & development. A win-win that works w/out out a government mandate

Moreover, the intervention is ridiculously cost-effective: for every $1 spent, society gained $65 in carbon benefits alone.
And that’s WILDLY conservative—it excludes health benefits, assumes only 1 year of adoption, and uses the low end of emissions reductions.

These results weren’t a fluke—kiln owners wanted to change.
Most adopted the new practices. Some even snuck into trainings they weren’t assigned to.
Most interventions fade. Not this one. Adoption rose the next season. Owners stuck with it. Stunning!

Their fix?
Low-cost tweaks to how bricks are stacked and coal is fed into kilns—no new equipment required. Just better training, and partnerships with kiln owners.

Regulation has failed. High-tech upgrades haven’t scaled.
But a unique partnership tried a new approach: understand kiln operators' real constraints—and align environmental progress with their incentives.

In Bangladesh, 7,000+ coal-fired brick kilns ring cities like Dhaka. They cause up to 40% of deadly air pollution. Air pollution harms health, productivity and shortens lives.
Residents live nearly 9 years shorter than they should.

How did one county prevent people from falling into homelessness by over 80% & generate $2.47 in public benefits for each $1 spent on the program?
and what does this mean for other counties tackling homeless?
really impressive work by our friends at Santa Clara County & LEO.
