Professor of behavioral genetics with my own twins. I mix behaviour and genetics at Tartu & McGill to understand obesity. I also mix global music as a DJ.

Addiction has become the default framework for interpreting problematic social media use. It shapes how it is measured, discussed, regulated, and what support young people are offered. But does it match the experiences of young people who report feeling addicted to social media? 🧵(1/7)

Väide on täitsa tõene. Thiel ja ta kaaskond just sellest räägivad. "Ta väidab, et tehnoloogiamaailmas leidub inimesi, kes ei võta inimkonna kadumist tragöödiana, vaid järgmise sammuna evolutsioonis. Üks tema tuttav olla öelnud: „Inimesed on asendatav liik.“" ekspress.delfi.ee/artikkel/120...

SocArXiv now has a limit of two papers per week. If authors submit more than that we assume they are LLM-generated and reject them all. Normal humans who need to upload a batch of papers, which sometimes happens, must make arrangements. Also today, ArXiv set a two papers per month limit.

New trial of retatrutide (triple agonist, building on GLP-1s), shows 25% weight loss in the highst-dose group. 25%! Just a few years back, a trial with 10% weight loss would have been big news. These drugs are the biggest public health boon since antibiotics and vaccines.

In the phase 3 TRIUMPH-1 trial involving patients with obesity, retatrutide, a triple hormone receptor agonist, resulted in substantial weight reduction and a decrease in knee osteoarthritis pain and obstructive sleep apnea events. Full trial results: https://nej.md/4ycgSHz

A graph from an Original Article published in the New England Journal of Medicine article titled "Retatrutide, a Triple Hormone Receptor Agonist, for Treatment of Obesity." The graph shows effect of retatrutide on body weight. The trial name, TRIUMPH-1, is in parentheses after the title. The NEJM identity sits at the bottom.

Hey friends, trying to find a reviewer who could provide a review on an empirical EMA paper focused on emotion regulation. I've had 31 declines so getting a little desperate and feel really bad for the authors. Let me know here or per email (firstnamesecondname@gmail.com)

So… we just found out that GPT sol can complete a complex online behavioral/cognitive study producing nearly indistinguishable behavior and subjective reports… right as we are about to launch. Is this doomsday for online cognitive testing?

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.

Amazon's market dominance has actually destroyed adjacent industries, as well as inflating prices across entire market segments and destroying our ability to comparison shop and effectively find the best product for our needs. Here's how:

Amazon's own balance sheet presents the most compelling evidence that we are stuck in the Enshittocene, the era in which everything is turning into a pile of shit, because the worst ideas of the worst people now make the most money. 1/

Hieronymus Bosch's 'The Conjuror,' a painting depicting a medieval con artist playing a shell game for an audience of astonished peasant rubes. The image has been altered: the conman now has Jeff Bezos's grinning head, and the mouths of all the peasants have been replaced with inverted Amazon 'Smile' logos, so they are now frowning.
