Happy #WomenInScience day - I've had the privilege of working with many brilliant women during my career, and am always acutely aware that they often have to work harder, be smarter, and do better to be taken equally seriously. Hopefully, we can keep doing better moving forward.

The ggseg ecosystem finally has a proper home! 🧠

For those who don't know, ggseg is an R package ecosystem for visualizing brain atlas data. Think ggplot2, but for brains.

Dark blue hexagon, with a light blue frame. Features a brain facing the left, with the front half as a wire-frame mesh of light blue, and the back half with several polygon segments of different colours. Below is written "ggseg" in light blue.

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

With @jessicahullman.bsky.social and @statmodeling.bsky.social

juliarohrer.com/wp-content/u...
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.

The extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

Paper out today in @nathumbehav.nature.com:

1) those groups (women, African Americans, lower SES, rural) that are underrepresented in science have been less trusting of science.

2) If you improve representation in science, you improve trust among those groups.

I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...

Our paper on the ☀️ "summer slide" 🛝 is out now @pnas.org!

Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️

The "smartphones/social media" discourse suffers from some amazing historical amnesia. There was no 2008 financial crisis and no global pandemic starting in 2020, it's all SCREENS SCREENS SCREENS. Major world events? Just the backdrop against which SCREENS happened.

An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.

Harvard Gazette: Gazette: “You are the mother of two In ten years you have produced three novels and two short-story collections. Can you talk about your process and how you manage work and family?” Groff: “I understand that this is a question of vital importance to a lot of people, particularly to other mothers who are artists trying to get their work done, and know that I feel for everyone in the struggle. But until I see a male writer asked that question, I am going to respectfully decline to answer it.”
