I love this story.
A reminder of the inspiration of teachers in education throughout our careers.

Wow this is a breakthrough in validation of predictive models that fully accounts for point estimates used in predictions being only point estimates. Great work @richarddriley.bsky.social and colleagues! #Statistics #StatsSky

Sounds cool!

What’s a multiverse good for anyway? Julia M. Rohrer, Jessica Hullman, and Andrew Gelman Multiverse analysis has become a fairly popular approach, as indicated by the present special issue on the matter. Here, we take one step back and ask why one would conduct a multiverse analysis in the first place. We discuss various ways in which a multiverse may be employed – as a tool for reflection and critique, as a persuasive tool, as a serious inferential tool – as well as potential problems that arise depending on the specific purpose. For example, it fails as a persuasive tool when researchers disagree about which variations should be included in the analysis, and it fails as a serious inferential tool when the included analyses do not target a coherent estimand. Then, we take yet another step back and ask what the multiverse discourse has been good for and whether any broader lessons can be drawn. Ultimately, we conclude that the multiverse does remain a valuable tool; however, we urge against taking it too seriously.

New preprint! So, what's a multiverse analysis good for anyway?>

5 Things We Learned About Journal Peer Review in 2025 - Absolutely Maybe Back in 2019 I wrote a couple of posts summarizing what we had learned from research about peer review at journals. Since…

Lots to think about in my annual roundup of peer review research:
- AI, mostly bad; some suggestions of ways it may help
- Evidence on financial rewards for peer review
- Influence of editors' biases
More on equity & diversity; librarians & systematic reviews

I feel like someone’s gotta say something, so I guess it’s going to be me. I’m 100% certain that p-values are useful.

Plot of modeling new NIH grants after a switch to 100% MYF. There is a large drop in grants in the first year with a gradual recovery over 5 years.

There is a lot of talk lately about multi-year funding (MYF) at NIH. This is mostly a paperwork issue, but it can have a dramatic impact on the number of grants that get funded. I was curious how this would impact grant numbers over time, so I did some simple modeling. 1/n

National media should really be covering the fact thay every major school, museum, and arts institution in the Twin Cities, and hundreds of local businesses are closed tomorrow to protest federal occupation.

Nothing like this at this scale has happened anywhere in America anytime in living memory.

The US has officially terminated its partnership with the World Health Organization.

Gratitutde to all NIH study section participants who are participating in rescheduled meetings now and in January. Thank you for your service and thanks also to the hard working NIH staff who are making these happen. 🥰🧪

The way I see it, we have a few options:

1. General strike

2. Mass protests in DC for as long as it takes

3. Wait for Republicans to protect the country and therefore lose the country

No one is coming to save us.

Academic publishing is for academics not for profit. That’s one thing, and one thing academics can do for themselves and colleagues. Choose where you submit and volunteer time reviewing and editing thoughtfully.

Academic publishing is in trouble and GenAI is causing these problems to float to the surface in dramatic ways.

Yes we do; no chat can’t. I agree the problem identified in the abstract is with “editorial checks”. Might also be bad actors but that requires case by case adjudication. The problem is not the analysis of existing data.

Maxwell was rescued from Nairobi National Park as a calf. He's blind – and because rhinos use vision to assess rivals, he can never safely return to the wild. We built him a boma within the National Park, a special home to call his own, enjoy mud baths and interact with neighbours: swt.bio/maxwell

Excited to share a new paper just published in Neuroepidemiology! We used 22 years of longitudinal data from the Health and Retirement Study to answer a surprisingly unsettled question: How fast does memory decline in older adults without dementia? 🧵👇

🧠 A major study in Nature Medicine challenges common belief about education & dementia protection: higher education didn’t slow brain ageing; it provided a higher starting point. This advantage may be established in childhood, not built through schooling itself.

Multi-Year funding analysis, a 🧵

I have been trying to find a robust way of quantifying and understanding multi-year (forward funding).

First, some background:

Most NIH grants are for multiple years (2 to 5, typically).

However, the are usually funded on an annual basis.
