when to use which of those types for what research questions (selection seems convenience-based), which types of inferential slippage are most damaging, and how to reconcile individual vs. collective behaviors (which are still composed of individuals and can sometimes be studied as such).

Thanks for this work. I enjoyed reading it, and I find it useful to name all these types of heterogeneity, even if we still end up with an awkward combination of intent, consequence, domain, person property vs. event, etc. My main confusion is now ...

Pro-environmental behavior is often used as a broad ☂️ term under which different behaviors (e.g., mitigation, conservation, restoration), sustainability approaches (e.g., sufficiency, efficiency), types of behavior, domains (e.g., mobility, energy, food), and their antecedents are summarized.

This eerie mosaic depicts Winter holding a bare branch and wearing a birrus (a hooded cloak used extensively in ancient Britain). Its use of cool blue colours, the seeming melancholy in the face & the sparse pale background really conveys the cold barrenness of winter. 🏛️Bignor 📷 mine #MosaicMonday

Yes, great example, thank you. I teach this history of protest in Amsterdam. It is perhaps a better case than Paris to reveal the feedback loop between individual actions, policy and infrastructure change, and back to individual actions.

Paris invested heavily in bike infrastructure and saw a massive increase in ridership. Does anyone know about research on where the willingness and investment came from, e.g., attitudes, priorities, city-level meetings, national conversations? How do such changes in policy and infrastructure emerge?

Cameron Brick @cameronbrick.bsky.social · 06/02/2026
Yeah. It's not just bad coverage in education. The more fundamental problems I think are the lack of error correction either during peer review or after publication; there being no consequences for a paper getting it wrong.

theconversation.com/we-got-lazy-... Lots of debate in NL right now about our wealth tax and the changing rules. There's uncertainty and I think that also causes distaste. If it was just 'the way we do it' it would be easier to be proud of what values and benefits it supports, maybe?

Stimulating. I have adapted from Buddhism as well, more for academic psychology than for politics. Agreed that compassion is not conditional on the target in moral terms. Instrumentally, I don't see rapid societal change through without winners and losers, heroes and villains, as we wrote about.

Well, I like your writing and argument. I hear a lot on the left that we need as wide a tent as possible, but in practice championing seems to expose political vulnerability. Maybe part of this is short vs long term success. Certainly disenfranchisement is unstable and unjust.

Finally, @bjoernhommel.bsky.social's and my paper introducing the SurveyBot3000 is officially out in AMPPS. It's a fine-tuned language model that guesstimates correlations between survey items from text alone. Not perfectly, but useful for search, for example. journals.sagepub.com/doi/10.1177/...
Fig. 3. Scatter plots of the synthetic and empirical estimates, validation study (Stage 2). Showing N = 30,135 item-pair correlations, N = 257 scale reliabilities, and N = 1,568 scale-pair correlations for (top) the pretrained SBERT model and (bottom) the fine-tuned SurveyBot3000 model. SBERT = all-mpnet-base-v2 model.Fig. 4. Prediction error of the synthetic estimates, validation study (Stage 2). Our prediction model allowed the error term to vary freely according to the predictor, the synthetic estimate. The thin-plate splines show that some synthetic estimates were predictably more accurate.
Fig. 5. Accuracy by domain. Accuracy differed across domains. SurveyBot3000 accuracy (colored) was always higher than SBERT accuracy (gray). Results were largely consistent whether accuracy of items was tested (left, circle) within domains or (right, cross) across domains.Fig. 1. Multistep training procedure for the SurveyBot3000, which produces synthetic estimates of interitem correlations. (a) Pretraining base model (SBERT). (b) Fine-tuning SurveyBot3000. (c) Validation. SBERT = all-mpnet-base-v2 model.
