How (not) to encourage sustainable travel - on the 1st of July, I will be speaking at a BeScy event together with ​Mike Daniels from The Behavioral Architects and Mike Scott from Cycling UK about the possibilities and limits of behavioral science for changing travel habits lu.ma/28rihhmh
How (not) to encourage sustainable travel? · Zoom · Luma
How would you encourage people to ditch their petrol guzzling, congestion creating car? How would you get citizens out on their bikes, on the bus and trains…

Denmark is best in EU in getting workers back into jobs (twice the average rate). They also do tons of RCTs to find out what works and apply behavior science. Can’t say it’s causal, but it’s an interesting correlation at least.

I 2024 var Danmark bedst i #EU til at få ledige i job. 40,8 pct. af de ledige i et givent kvartal, kom i job i det efterfølgende kvartal, hvilket er væsentligt over EU-gennemsnittet på 24,2 pct. Det er 14. år i træk, at Danmark er EU-mestre i at få ledige i job #dkpol www.ae.dk/analyse/2025...
Danmark er EU-mestre for 14. år i træk: Bedst til at få ledige i job
Gennemsnitligt 40,8 pct. af de ledige i et givent kvartal kom i job i det efterfølgende kvartal i 2024. Det er den højeste andel i EU – for 14. år i træk. Danmark er også bedst til at få langtidsledig...

I have been thinking whether I can somehow include it in my fall class, but its a bit far off topic for that one. But I‘ll recommend it to others and my students in general. I shared it on LinkedIn a while back as well to counter the hype.

I still have one of your „bullshit“ talks (from 2021) as a homework assignment for my students and have them choose their favorite bullshit examples and then we discuss them in class. I am a big fan of you work and LOVE the new AI course. Thanks for providing these resources!

Absolutely loved this mini course to think critically about GenAI! Can only recommend it to anyone!

Modern-Day Oracles or Bullshit Machines?

Jevin West (@jevinwest.bsky.social) and I have spent the last eight months developing the course on large language models (LLMs) that we think every college freshman needs to take.

University of Copenhagen and Zurich are dominating this innovation in field and survey experiments workshop @wzb.bsky.social 😄 so many cool experiments with important policy impact

Day 1 of the Workshop on Cognitive Foundations of Decision Making with presentations by @kaibarron.bsky.social @clarasievert.bsky.social @enhuahu.bsky.social Menglong Guan, Natalie Lee, Paul Grass, Julian Matthes, Luigi Butera, and Benjamin Enke.

Please send it when it’s done!

Interesting! What’s the mechanism for that? They overestimate sales?

Excited to host Benjamin Enke as this year’s Zeuthen lecturer the University of Copenhagen. The lectures run over three days and are complemented by a workshop on the cognitive foundations of decision making.

Our publication on how multi-buy offers increase unplanned overbuying and how this can increase food waste at home is out and open-access! This was probably one of the most complicated field experiments I ever ran, but also one I am very proud of: rdcu.be/enmFi
In-store food promotions increase sales as well as household food waste

Thanks, that one indeed looks good. But also here it’s more a lab in the field experiment with clearly defined tasks. It is not obvious that the productivity gains will translate to real legal work and thus markedly increase productivity. But it’s a good step.

Only one year after replacing their customer service and marketing team with AI agents, Klarna is regretting the decision and trying to re-hire workers. The quality was just too low to justify the cost-savings. So looks like AI isn't taking your job, just yet. futurism.com/klarna-opena...
Company Regrets Replacing All Those Pesky Human Workers With AI, Just Wants Its Humans Back
Years after outsourcing marketing and customer service gigs to AI, the Swedish company Klarna is looking to hire its humans back.

This also raises some questions about PhD supervision and data protection at MIT - some supervisor would have needed to sign a data sharing agreement and a secure server would have been needed for the data. That’s a lot of paperwork.

I think the study is interesting, but the total time of the study was 5 hours, the tasks were carefully chosen, and the consultants who participated selected. I think there is no doubt that AI can speed up coding or writing, but I haven't seen much on how that impacts firm productivity.
cgravert.bsky.social
And harm to the companies using results like this to spend billions on tools that don't work. So far there is very little evidence that AI tools increase productivity for complex tasks. This fake study was one of the only ones.

There is special circle of hell for those who fabricate data

Immeasurable harm to all of us who break our backs to collect real data, to brilliant students who deserved that position, to other students who won’t get trust they deserve — just obscene
MIT Says It No Longer Stands Behind Student’s AI Research Paper
The university said it has no confidence in a widely circulated paper by an economics graduate student.

One of the best AI papers on productivity turned out to be made up - so disappointing! I really liked the paper and had it saved as „best paper on AI“. Too good to be true! As much of AI claims to fame. www.msn.com/en-us/money/...
