Confusion in gaming disorder measurement Abstract. Measurement is important for the scientific programmes of addictive behaviours. In the present study, we investigated the measurement of gaming d

First post of the year, new paper out today: we present possibly the biggest case of systematic Measurement Schmeasurement in tech use. It seems that most studies on gaming (videogame) addiction/disorder haven't measured gaming after all. This research took years, so long 🧵 doi.org/10.1098/rsos...

I had not heard of a "mode effect" until @georgiatomova.bsky.social invited me to be part of this paper.

If you've not heard of them either, I'm thrilled to share our introductory paper (with DAGs!) in @amjepi.bsky.social

Turns out they're really important for anyone using survey data!

I genuinely had no idea #rstats technically has a module system.

my_module <- new.env()
source("helpers.R", local = my_module)

my_module$add(1, 2)

"in particular mice methods tend to have the best performance. Despite their growing popularity, deep learning-based joint imputation methods, such as miwae, gain, miracle, and remasker consistently underperformed in our analysis." #statistics #statsky #academicsky #skystats

Call for Papers: Psychometrika Special Issue - Psychometric Society Data Intensive Methods in Psychometrics

Excited to share a new call for papers for a special issue in Psychometrika focused on Data Intensive Methods in Psychometrics that I'll be guest editing with @kyliegorney.bsky.social, @jmbh.bsky.social, @leonievogelsmeier.bsky.social, and Ben Domingue: www.psychometricsociety.org/post/call-sp...

Waffle chart showing James Bond's weekly alcohol consumption across 12 novels. Each gold square represents one unit of alcohol. The chart is faceted by book title and year of publication, with consumption rates ranging from 52.4 units per week (Goldfinger) to 132 units per week (You Only Live Twice). Numbers labelled on each facet show the weekly consumption total.

For this week's #TidyTuesday, I visualized James Bond's drinking habits across the 12 novels using a waffle chart, based on the 2013 study "Were James Bond's drinks shaken because of alcohol induced tremor?"

An Audit of Social Science Survey Experiments Abstract. Survey experiments have become a popular methodology for causal inference across the social sciences. We study the efficacy of survey experiment

Needed - larger samples, more realism about (the lack of) heterogeneous treatment effects:
-"less than a third of proposed hypotheses were supported... the largest predictor of positive exp. results was sample size"
-"moderation hypotheses were rarely significant"

New chart from Mike Males using MTF and Pew Research data finds that trends in teen social media and smartphone use are unrelated to teen loneliness (which hasn't changed much over the years anyway aside from an unexplained dip in the 2000s).

new paper by Sean Westwood:

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

Advances in Statistical Model Evaluation Submission deadline: 31 December 2026 The Special Issue accepts theoretical, methodological, applied, and philosophically oriented research on frequentist, Bayesian, and information-theoretic advances in statistical model evaluation.

Topics of interest for this call for papers include but are not restricted to: • Methodological advances in fit assessment, parametric bootstrapping, cross-validation, and/or other frequentist model evaluation methods • Methodological advances in prior and/or posterior predictive model checking, specification and use of informed priors, Bayes factors, and/or other Bayesian model evaluation • Methodological advances in minimum description length, normalized maximum likelihood, and/or other information-theoretic model evaluation methods • Practical applications and tutorials of advanced model evaluation methods • Philosophy of science issues underlying statistical model evaluation • Critiques/perspectives/commentaries on statistical model evaluation

Announcement: I am excited to be co-editing (with Li Cai) an upcoming Special Issue of the Journal of Mathematical Psychology on "Advances in Statistical Model Evaluation." Proposals due Feb 1. Details: www.sciencedirect.com/special-issu...

Goodness gracious.

This study was made possible through a fruitful collaboration with 👉 @jpstein.de, Sabine Zinn, Florian Griese, and @markusappel.bsky.social.

- Direct experience with AI was still rather limited — especially in healthcare and education.

📊 In sum, while AI is broadly accepted across domains in Germany, first-hand experience remains relatively scarce.

Key findings:
- Overall, respondents expressed favorable attitudes toward AI.
- Healthcare applications of AI were viewed more positively than those in the work context.
- Cognitive evaluations were more positive than emotional or behavioral responses.

💡 How do people in Germany perceive Artificial Intelligence (AI)?

In our recent population survey in Germany, we examined attitudes, experiences, and usage intentions regarding AI in work, healthcare, and education.
