"I Have Already Settled It for Myself" Publication day notes on what we can learn from a preschooler about making art

It's publication day for ORIGINAL SIN! On Substack, I wrote about my pub day jitters, and what my 3-year-old has to teach me about making art:

"AI detectors" are themselves AI, and yet are endlessly trusted by people on here if they say that a newspaper article is AI.

AI detectors are snake oil. None of them reliably works. And UK broadsheet are not yet using AI to write articles. No, that link to the deal you found doesn't prove it.

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.

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.

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.

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.

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.

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.
