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.

Does anyone use #RedCap for child participant database management? If so, would you be willing to share screenshots etc. of what your user interface looks like or share the template, whichever is easier.

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.

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.

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.

former CDC official Dr. Houry: "I first learned that the secretary had changed our CDC covid vaccine guidance on an X social media post. CDC scientists have still not seen the scientific data or justification for this change. That is not gold standard science."

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."

New people are signing our open letter almost everyday, and it is so heartening to see. Especially good to see familiar names sign.

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.

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

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.

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.

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)

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 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.

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.

Academics:

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/

The psych job market isn’t dead! Join us at UIC!!! We are looking for a clinical psychologist (assistant or associate level)!! Chicago is simply the best, and the department is incredibly lovely! I’m not on search committee, but as the “newest” hire, I’m happy to talk about my experience thus far!

This is excellent!

Trust in elections rises after ‘inoculations’ meant to preempt false fraud claims New U.S.-Brazil study points to ways of countering election misinformation, political scientists say

New study by @brendannyhan.bsky.social, @jasonreifler.bsky.social & colleagues demonstrates that prebunking election fraud rumors — by warning about anticipated false claims & filling conceptual gaps that those claims exploit — helps to reduce belief in falsehoods: www.science.org/content/arti...
