The volume of social psych papers that ran on prolific and mturk is going to need to shrink soon, and that will have a big impact on a lot of small labs

If we want this to change, then we need to make it feasible TMP factor: Time, money, pain Whether a study gets done depends a lot on how difficult it is. The question is one of ROI. I suspect many researchers are thinking to themselves, “that’s a great thing, but it’s not something I can do”

We have progressed from data collection to data analysis.

this slide is from a colleague's introductory stats course, I think it fits many statisticians' experiences

45. Academia doesn't reward building useful tools nearly as much as it should

14. We mostly evaluate latent variable models with the equivalent of Rorschach tests

5. You should use a precision-recall curve for a binary classifier, not an ROC curve

Wow. Scientists have edited mosquito DNA to prevent the spread of malaria to humans "while supporting essential physiological functions... and negligible fitness costs" to the mosquito population. Potentially ending the mosquito-born spread of malaria to humans. www.nature.com/articles/s41...

Curious how this compares to the cost of living per state

Let's say you want to include age as a predictor in your model. How do you do that? Here's an illustration of three options -- it's for a paper I'm working on (so if you feel like anything could be tweaked...).

🤖Thrilled to share our latest work☄️ Have you ever wondered what LLMs know but they are not saying? We built an auditing framework to study information suppression in LLMs, and demonstrated it to quantify and characterize censorship in DeepSeek. Read more: arxiv.org/abs/2506.12349

Someone please explain why linear algebra isn’t taught more in high school in the United States? Seems like maybe if you’re lucky you get a few lectures on matrices and that’s it.

Is it 2015 or 2025?

Under the Trump agenda, energy will cost more. And when energy costs more, everything costs more. www.nytimes.com/2025/06/04/c...

Many academics are taught “do more” instead of “prioritize”. They are taught the academic superhero myth, that “truly great/smart” scholars can handle it. So they sabotage their own success in service to the cult of personality

I love this technique because it gives a cool way to isolate change and stability components of within-person measurement using latent variables. The stable portion of IATs is far more predictive of other individual-difference measures than one would think given traditional scoring/analyses

That moment when you had completely forgotten about a cool data app you’d made, only to find others posting about it ;) Thanks @calvinklai.bsky.social!

Paper w/ @tcarpenter.bsky.social & @alexgoedderz.bsky.social at PSPB!🚨 The standard IAT is only 5 min long. We found that making the IAT longer by taking it multiple times greatly improves predictive validity. 🧵below, with practical advice about how to run IATs! LINK: osf.io/preprints/ps...

BOTTOM LINE: Aggregating 2 IATs together and using CFA can lead to much higher predictive validity. Finally, I wanted to thank Tom and Alex! This paper came out while they were moving out of academia & I was going on parental leave, so we hadn't publicized it. Better late than never! 😉

FAQ Q1: 4 IATs is a lot!? A: You only need 2 IATs to reap the benefits of aggregating. Q2: It's a lot of work to set up these models. A: Here's a shiny app to make it easy: tcarpenter.shinyapps.io/trait_iat/ Q3: I don't want to learn CFA. A: Averaging IATs together gets you some of the benefits.

What should universities look like 10 to 15 years from now? Lots of intersecting headwinds… dramatic change is likely. Biggest IMO is that teaching universities become cheap again by reverting to “room with chairs and a prof”. Think community college, but with amazing faculty.

Fitting Bayesian models and finding it tedious to iteratively run prior predictive checks and tweak my priors. I’m thinking of a way to automate it. I know the plausible distribution of the data + plausible values for the parameters. The hard part is reconciling them.

Has anyone fit bayesian models with brms in Spark's implementation of R (sparkr)? What's your experience?

“It seems that after contracting COVID-19 in pregnancy, the placenta is exhausted by the infection, and can’t recover its immune function.” Studies also suggest that babies born to mothers who had Covid at ANY point in pregnancy will need to be monitored as they grow:

The more I use AI to teach myself new skills, the more convinced I am that this is one of THE best ways to learn (especially if you have to learn selectively and quickly). However, strategy matters here. I threw some thoughts on using AI for skilling here. www.linkedin.com/posts/tompca...

This is an excellent illustration of interaction effects with a (far too) resonant example.

The lesson in this story is that doing a good job doesn’t matter if no one knows you’re doing a good job so some self promotion is necessary. I think there’s a different lesson in the title — a promotion isn’t from doing your job well, eventually it’s showing you can also do your boss’s job well.

The Star Wars prequels are a trilogy about how an unfair and severe galactic tariff policy causes instability in the democratic political order that ultimately enables an authoritarian to seize power under the guise of restoring peace and prosperity to the republic. Why does this sound familiar….

Bottled water is a big ole bottle of microplastic. Don't buy it, support utilities so everyone has access to clean, less plastic-filled water. My university has a project to vastly improve how we monitor tap water but until NSF and its workers are restored, I fear that is on hold. 🧪 🚰
