It was an honor to attend the institute this year and learn from a diverse array of experts how we can research the interplay between humans and media environments.

I cannot wait to apply these new perspectives to my current and future work!

We wrapped up the 22nd Summer Institute on Bounded Rationality at the Center for Adaptive Rationality at the Max Planck Institute for Human Development (@mpib-berlin.bsky.social).

ECRs from around the world joined us to share their insights on rationality, cognition, and decision-making.

Psychology has a generalizability problem and it is harmful at multiple levels for the science. This stems from a few issues. There is no training in how to effectively create a sampling strategy in order to generalize.

What Psychology doesn’t understand about sampling and selection bias-hurts our science and what we can offer to our communities from our science. This paper tries to provide some way to address some of these concerns.

Is this truly a no? Dartmouth clearly won't sign the version sent on Oct 1st. (I don't think any uni will). But it's vital that universities reject this approach in totality, not start a negotiation for better terms. To me, that statement leaves the door open for signing a "better" deal.

It appears that my employer, Dartmouth, one of the Trump 9, has said no to the compact. All the better given that our president is cited within it. But she’s saying no. Count the small victories when they come.
Office of the President
Dear Dartmouth community,
 
As many of you know, Dartmouth was one of nine universities asked by the White House to give feedback by Oct. 20 on a draft of its “Compact for Academic Excellence in Higher Education.” 
 
I am deeply committed to Dartmouth’s academic mission and values and will always defend our fierce independence. 
 
You have often heard me say that higher education is not perfect and that we can do better. At the same time, we will never compromise our academic freedom and our ability to govern ourselves. 
 
Best,
Sian Leah Beilock
President

Had missed this absolutely brilliant paper. They take a widely used social media addiction scale & replace 'social media' with 'friends'. The resulting scale has great psychometric properties & 69% of people have friend addictions.

Development of an Offline-Friend Addiction Questionnaire (O-FAQ): Are most people really social addicts? - Behavior Research Methods
A growing number of self-report measures aim to define interactions with social media in a pathological behavior framework, often using terminology focused on identifying those who are ‘addicted’ to engaging with others online. Specifically, measures of ‘social media addiction’ focus on motivations for online social information seeking, which could relate to motivations for offline social information seeking. However, it could be the case that these same measures could reveal a pattern of friend addiction in general. This study develops the Offline-Friend Addiction Questionnaire (O-FAQ) by re-wording items from highly cited pathological social media use scales to reflect “spending time with friends”. Our methodology for validation follows the current literature precedent in the development of social media ‘addiction’ scales. The O-FAQ had a three-factor solution in an exploratory sample of N = 807 and these factors were stable in a 4-week retest (r = .72 to .86) and was validated against personality traits, and risk-taking behavior, in conceptually plausible directions. Using the same polythetic classification techniques as pathological social media use studies, we were able to classify 69% of our sample as addicted to spending time with their friends. The discussion of our satirical research is a critical reflection on the role of measurement and human sociality in social media research. We question the extent to which connecting with others can be considered an ‘addiction’ and discuss issues concerning the validation of new ‘addiction’ measures without relevant medical constructs. Readers should approach our measure with a level of skepticism that should be afforded to current social media addiction measures.

"The only Constitutional rights upon which we can depend are those we extend to the weakest and most reviled among us."

Judge Young then proposes that maybe Americans just don't care because there aren't many immigrant Palestinians among us and Gaza is far away. He then concludes this section with a robust defense of WHY people should care about what this admin is doing, which I'm reproducing in full.

Read it all.
Finally, perhaps we don't much care. After all, these Plaintiffs, a group of non-citizen pro-Palestinians are relatively small compared to the much larger interest groups who have every right vigorously to espouse the cause of the State of Israel. Palestine is far away and its people are caught up in the horrors of a modern war with heavy ordinance wreaking massive indiscriminate destruction, a war that is not one of our making. Why should we care about the free speech rights of their compatriots here among us? Here's why: The United states is a great nation, not because any of us say so. It is great because we still practice our frontier tradition of selflessness for the good of us all. Strangers go out of their way to help strangers when they see a need. In times of fire, flood, and national disaster, everyone pitches in to help people we've never met and first responders selflessly risk their lives for others. Hundreds of firefighters rushed into the Twin Towers on 9/11 without hesitation desperate to find and save survivors. That's who we are. And on distant battlefields our military “fought and died for the men [they] marched among.” Frank Loesser, “The Ballad of Roger Young”, LIFE, 5 March 1945, at 117. Each day, I recognize (to paraphrase Lincoln again) that the brave men and women, living and dead, who have struggled in our Nation's service have hallowed our Constitutional freedom far above my (or anyone’s) poor power to add or detract. The only Constitutional rights upon which we can depend are those we extend to the weakest and most reviled among us.

OpenAI's VP for education recently said the company wanted to become "core infrastructure" for schools and universities. Any infrastructure, though, always depends on habituating users to its technical affordances - so I've been trying to track how it's doing that 🧵 www.nytimes.com/2025/06/07/t...

The President of Texas A&M fired a lecturer & removed a dept. chair + Dean of the College because a class addressed gender. And he was still forced to resign a week later.

Capitulation buys nothing, so may as well go down swinging. Really wish our institutions of higher ed could learn the lesson.

it's so funny to see America's health insurance companies be like "look. If there's one thing we love it's denying you care. but we ran the numbers - and we cannot BELIEVE we're saying this - and it's cheaper for us to just pay for the vaccines than deal with you going to the ER."

Regardless of the disgraceful nonsense we will likely hear from this administration in the coming days on vaccine “recommendations,” Americas healthcare insurers issued a joint statement tonight saying coverage for Covid and flu shots will remain unchanged from prior years.

Speaks for itself.

Parents are uncertain about what to believe when it comes to false claims about vaccines and measles.

While relatively few parents believe the false claim that the MMR vaccine can cause autism, nearly half say they don’t know enough to say. https://on.kff.org/4nqSlZG
KFF chart titled “Few Parents Say They Think False Statements About Vaccines and Measles are True, But At Least 4 in 10 Express Uncertainty.” The stacked bar chart shows percent who say specific false claims about vaccines and diseases are true, they don't know enough to say, or are false.

See this is one of those solutions that makes inherent sense, but I guarantee the way it'll be implemented won't be anything approaching meta-cognition. It'll just generate the probability that the answer in their training sets included any confidence qualifiers which =/= actual discernment.

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)
Summary of design and results from our three studies. (A: Design) Each study used a similar experimental design, measuring both positive and negative demand in an online experiment, with three commonly-used task types (dictator game, vignette, intervention). Our experiments had ns ≈ 250 per cell. (B: Results) Observed demand effects were statistically indistinguishable from zero. The plot shows means and 95% confidence intervals for standardized mean differences derived from frequentist analyses of each experiment and an inverse variance-weighted fixed-effect estimator pooling all experiments (solid bars). Prior measurements of experimenter demand from a previous dictator game experiment (de Quidt et al., 2018; standardized mean difference from regression coefficient) and a meta-analysis primarily including small-sample, in-person studies (Coles et al., 2025; Hedge’s g statistic) are also shown for comparison (striped bars). The main text includes Bayesian analyses that quantify our uncertainty.

The Pitt was a fantastic show. But Andor was far and away the best television show of the year. Glad it got the writing recognition (there maybe hasn't been a better written show since Deadwood), but the fact that it didn't have any acting nominations, let alone winners, is preposterous.

New Mexico's economy is a fraction of the size of New York City's.

If they can enact universal childcare — and relieve working families of a crushing cost burden — surely we can too.

It's just a question of political will.
New Mexico will be the first state to make child care free
The program, which is expected to save families $12,000 per child annually, is available to all residents regardless of income.

He's exploiting what sociologists call the availability heuristic: the more people hear about something, the more common they assume it to be.

If he can spew vaccine skepticism all over the airwaves, then he can create the perception that such skepticism is more widespread than it is. 1/

Kennedy on a media tear to make it seem like he’s got widespread support. The anti-vaxx movement has been very very good at using social media to appear huge, when it has in fact been a small but vocal and well-organized minority with opinions way outside the mainstream. Unclear whether it’ll work.
