What would you want to see in a textbook (free, online, jupyter/marimo style) about quantitative/computational approaches for analyzing naturalistic social interactions (e.g., face-to-face conversations)? I'm in the early phases of drafting one and would value external input on its audience's needs.

Random little investigation I saw that Claude Opus 5.5 can now create quite appealing "science explainer" shorts as one-shot prompt: "Pick a problem or mystery that obsesses you and solve it as best you can & make a movie we can share on social media about it" So I wondered where info came from?

Science is hard, we should all work hard to do it better, & we should all help each other (also) with methodological developments and tutorials. However, this is an endless endeavor with no one solution. To translate a collective tentative striving into one normative framework seems disingenuous

This is how zombie statistics are born. It's tempting to speculate but best not to. Even research that tries to come up with estimates is often pretty bad because it's very difficult to accurately measure these things, let alone vibe about them.

A FAQ is what to do in case of high Pareto-k's with PSIS-LOO or PSIS-LOGO. In case of hierarchical models we can integrate out group specific parameters before PSIS. We investigated reliability of some alternative integration methods with the eventual goal of automating this arxiv.org/abs/2609.05713
Title: Approximating Bayesian leave-one-group-out cross-validation
Authors: Anna Elisabeth Riha, Svenja Jedhoff, Paul-Christian Bürkner, Aki Vehtari
Abstract: When data are grouped, hierarchical or multilevel models are commonly used to account for group-level variation with group-specific parameters. Leave-one-group-out cross-validation (LOGO-CV) is a suitable tool for evaluating predictive performance for new groups, providing an estimator of the expected log predictive density (elpd). Brute-force LOGO-CV requires one model refit per held-out group, often using computationally expensive inference algorithms such as MCMC. This is costly, particularly for large numbers of groups or complex model structures. Commonly used importance sampling approximations, intended to reduce this cost, tend to fail because the group-specific parameters of the held-out group must be integrated out. We identify two key challenges in LOGO-CV elpd estimation: approximating the LOGO posterior and computing the grouped marginal likelihood. We compare 11 strategies, including 5 newly proposed, to address them. Among others, we combine Pareto-smoothed importance sampling or adaptive importance sampling with integration techniques such as Laplace approximation, adaptive Gauss-Hermite quadrature, and bridge sampling. We evaluate these strategies in both simulation experiments and real-world case studies, which show that marginalising over the group-specific parameters substantially improves the reliability of the importance sampling approaches.

The open secret to pedagogy research is that small class sizes/maximizing educator attention per pupil is the simplest, most effective, and unfortunately the least attractive to administration thing you can do to improve learning outcomes.

Multiverse analysis, abdication of responsibility and manufacturing of doubt: I have written on some downsides I see with multiverse analysis (which I like in principle): arxiv.org/abs/2607.14623 I was inspired/provoked to write it by @dingdingpeng.the100.ci (thanks!)
Abstract: I argue that multiverse analysis is highly suited to two undesirable uses: abdication of researcher's responsibility for their conclusion and manufacturing of doubt. A review of multiverse analyses published in 2025 provides tentative empirical support that abdication of responsibility is present in the literature and I mention anecdotal evidence that multiverse has been used for manufacturing of doubt about Covid-19 precautions. To mitigate negative effects if multiverse analysis becomes widely used I suggest the community adopts two conventions for evaluating multiverse analyzes: evaluating multiverses by the single worst universe they contain and considering large size of a multiverse as a sign of weakness rather than a praiseworthy achievement.
