Maybe one's own discipline and background matter for the subjective impression. A lot of money seems to come from areas other than the social sciences, so there are likely many more published papers in those areas.

I always had the vague feeling that Scientific Reports and Nature Communications are mainly APC business models. A paper estimated the total APC for gold/hybrid Open Access per journal 2015–2018: doi.org/10.1162/qss_... Surprise, surprise - there are 2 outliers at the top😐

New preprint by @semihaktepe.bsky.social 🎉 We compare ANOVA/SDT/GLMM for binary judgments in 20 datasets of the truth effect. #lme4 Main conclusion: "GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

The method worked better than simple aggregation for validation words such as "fifty-fifty chance", "never" or "always" (indicated in the plot by the black intervals compared to the gray interval areas).

Just submitted a minor bugfix of RRreg to CRAN: github.com/danheck/RRre... The R package focuses on analyzing univariate & multivariate data collected with the Randomized Response Technique (RRT), which protects anonymity in surveys by randomly scrambling responses. I also added a new logo 🚀

of course, we also need a new badge!

New preprint by my PhD student @semihaktepe.bsky.social: Revisiting the Effect of Discrepant Perceptual Fluency on Truth Judgments osf.io/preprints/ps... We could not replicate the effect that higher color contrast results in higher truth judgments in two online experiments (N=98 and N=294).

In my lecture on statistical modeling, I illustrated the different types of true/observed/fitted/hypothesized covariance matrices that occur in estimation & testing of SEM/CFA models via hexagons and pentagons. I like the analogy, but probabably it is not valid in all aspects.

This reminds me of a paper of mine about the most extreme correlation matrices of individual (per-person) effect sizes that are mathematically possible: psyarxiv.com/ca8z4/ a) All correlations are as large as possible (1-factor model) b) All correlations are as negative as possible (weird model)

Daniel Heck @danielheck.bsky.social · 24/11/2023

Great paper: "Impossible Hypotheses & Effect-Size Limits" journals.sagepub.com/doi/10.1177/... 1) The correlation matrix of all population effect sizes must be positive definite. 2) Hence, there is a lower/upper limit to each effect size that is possible (even if we study only a subset of effects)

The website has changed once again.... A version control system would render changes in arguments more transparent.
