New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵
Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

A decade ago, a “weird” kitten was found on a road near a Bolivian forest. Too small to be a housecat, he had a scrunched-up face, short round ears, long whiskers, & a coat of leopard-like spots. DNA analysis now reveals him as the very first of a newly discovered species & I think I'm in love. 😻🧬🧪👇

On this point, there's a lot of cool things to say, one is: Guest, O. & Martin, A. E. (2026). A Metatheory of Classical and Modern Connectionism. Psychological Review. doi.org/10.1037/rev0... PDF: repository.ubn.ru.nl/handle/2066/...
We propose connectionism has a survival strategy honed by decades
of proverbial summers and winters; engineered high and low funding
periods (Boden, 2006; Dreyfus, 1965; Haigh, 2023; Lighthill,
1972; McCorduck, 2004; Olazaran, 1996). We will analyze such
historical narratives, but first we will examine how the metatheorical
calculus of M-connectionism is—perhaps unexpectedly given its
problematic structure—robust and transmissible. Before that, we
explain the uptake and deployment of the more mainstream calculus
of C-connectionism.

I won't show you all the demographic back and forth, but I'll show you just how easy it is to make an AI-administered survey good, even with the stupid AI tone ("honest" lol), you can dramatically improve LLM output with a good harness Here are inventory instructions: github.com/DrCatHicks/i...
Two honest boundaries up front, so they don't surprise you later: I won't recommend for or against EV, and I won't weigh in on dose changes — those are the oncology team's call. What I can do well here is help you build a clear picture of what to watch for, how strong the evidence behind the safety profile actually is, and what specific, well-timed questions to bring to their next appointment. We can also do this in pieces — answer what's easy now, and we can pick up the rest later.
Here's the inventory. The most important thing to know about EV is that its risk profile is very regimen- and person-specific, so a handful of these answers will genuinely change what I search for and what I tell you to watch. Answer what you can, skip what doesn't apply or you don't know.1. The regimen and setting — this one matters most.
Is this EV on its own, or EV plus pembrolizumab (often written "EV+P")? Pembrolizumab is an immunotherapy that adds a whole separate category of possible reactions, so knowing this reshapes the search. And roughly what setting — advanced/metastatic, or something else you were told?
2. Where they are in the course.
When did treatment start, and which cycle are they on now (or how many infusions so far)? Some of the most serious reactions cluster in the early cycles; others (like nerve symptoms) build up cumulatively over time. Timing changes what's most likely right now.
3. Baseline health that maps onto EV's specific known risks. Any of these that apply:

Blood sugar — any diabetes, pre-diabetes, or higher body weight? (EV can push blood sugar dangerously high, and this risk is concentrated in certain people.)
Nerves — any numbness, tingling, or weakness before starting treatment, from any cause?
Skin — any pre-existing skin conditions, or a history of bad drug rashes?
