Why does Coca-Cola sponsor research on obesity? Why did BP introduce the personal carbon footprint calculator? In our new working paper, we offer an explanation: emphasizing individual action shifts whom people hold responsible for solving the problem.

@davidhagmann @alexolegimas Very cool idea. Here's a first cut from ChatGPT for today, the 17th https://t.co/Qtwm1LxFtr

@alexolegimas I’d love a news source that took popular headlines from 1-2 years ago and reported on how they turned out. Even without additional reporting, I think a lot of headlines age very poorly

@ChrisMurphyCT You're being played by people who want regulatory capture. They are scaring everyone with dubious studies so that open source models are regulated out of existence.

Sometime ago i was contacted by some university admins about some procedural things that were totally unnecessarily complicated. I got spammed so much that I put them into a spam folder and forgot about it. This week while fishing for a coupon I accidentally discovered that all
There was a meeting with Duke med school leadership and they allowed anonymous questions to be submitted by faculty. One question was, given all the budget cuts and layoffs why are there so many vice deans and what exactly do they do? Awkward. But apparently many faculty members

This is an amusing policy (that I’m sure their staff is ignoring), but I just can’t imagine that someone thinks sharing this with a journalist makes their company look good. Clearly, they don’t understand absolute effect sizes and you can make your own inferences about what else

I was honestly surprised by my finding that activism had replaced science for many folks. I thought it was going to be a controversial finding and folks would be offended at the accusation. (Some are.) But what I'm seeing at ASC is: it's not only well known (by those who support
How has the normative turn in social science affected our ability to produce and use theory? Using a case study of punishment studies during/after the normative turn, I find authors are mistaking normativity for theory. Published today in @Theory_Society!

Econ seminar culture is built on the assumption that the audience knows something that the speaker doesn't, and that the speaker values that information. A very important thing the audience knows and the speaker doesn't: Is the speaker making any sense at all? If nobody has any

My student Michael Cuna is on the econ job market this year. He has an excellent paper showing the impact of the hidden curriculum on educational outcomes, particularly in the case of first-gen students. The paper also demonstrates the potential for AI tools to close these gaps.
@CunaMichae77590’s JMP studies the hidden curriculum—unwritten rules for success. Combining data and field experiments, he finds first-gen students engage less in key actions, e.g. networking, due to low awareness. Read more: https://t.co/vi1XlIj8S3

While a 50yr vs. 30yr mortgage doesn't do much in terms of affordability, I'm surprised there aren't any mortgages with increasing payments to account for inflation and wage growth. $2k/month in 2025 at age 25 is much harder to pay than $2k/month in 2055 at age 55

A recent SCOTUS case prompts a question I have sometimes wondered about: If you're counsel below, SCOTUS grants cert in your case, and all of a sudden all these hotshot SCOTUS advocates call you up and offer to represent your client pro bono, do you have an ethical obligation to

On AI safety lobbying: Fascinating to see the reaction on X to @DavidSacks post yesterday especially from the AI safety/EA community. Think a few things are going on (a) the EA/ AI safety / "doomer" lobby was natural allies with the left and now find themselves out of power.

I've seen a few conversations where someone says something like this: I've been using an open-source LLM lately -- I'm a huge fan of not depending on OpenAI, Anthropic, or Google. But I'm really sad...
Scott Weiner’s rushing to defend Anthropic tells you everything you need to know about how closely they’re working together to impose the Left’s vision of AI regulation.

Most correlations are not causal. Public health advice provides us with plenty of examples to understand 'Why?' Consider sugar. It's notably declined as a share of the American diet ever since dietary recommendations went out against it. The people who adopted the advice to

The progress of science is great example of non-Bayesian updating. It incredible how many resources need to be extended to move beliefs back to the null on concepts that became “canon” based on few underpowered studies. Beliefs are so sticky that it may not be possible at all.
Another replication finds no evidence for stereotype threat—the fear of being judged based on negative stereotypes about the performance (eg maths) of a certain group one identifies with (eg women)—like here, in 5 countries, by Stoevenbelt et al: https://t.co/PnAKMzCEpm

In a new paper, we find that sycophantic #AI chatbots make people more extreme--operating like an echo chamber. Yet, people prefer sycophantic chatbots and see them as less biased. Only open-minded people prefer disagreeable chatbots.

The US totally rejects all efforts by international bodies to assert centralized control & global governance of AI. Ideological fixations on social equity, climate catastrophism, & so-called existential risk are dangers to progress & obstacles to responsibly harnessing this tech
Today at the UN Security Council, Director @mkratsios47 shared the @WhiteHouse’s message on AI in a new era of international peace and prosperity. Global regulation of AI won’t lead to a safer world. Rather it will stifle innovation and centralize power. https://t.co/XUyUIZ48R0
