‘German has a word for everything’-experience of the day: Erstverschlechterung (lit: fore-worsening), the notion that when you change things, they tend to get worse a bit before they start getting better. Example: medication side-effects occurring before the healing effect starts

With some delay, my op-Ed on the dramatic Saxony-Anhalt election. It is high time we focus our political struggle on strengthening democracy, rather than merely weakening the far right. To do this, we must show realism, resilience and restraint.

Finally had time for Ursula K Le Guin’s The Dispossessed. If there’s any more proof you need that even the most fundamental scientific endeavour is deeply political, if only because of the system that makes the work possible, this is the book for you

The negative effects of even a small amount of alcohol on our health are indisputable. It’s fascinating to watch what happens when this fact gets communicated to the general public: Health promotors seem incapable of considering the value of drinking alcohol as a social practice
Tweet by @firstdoctor saying “Alcohol has no single benefit. Zero. Not one.”Two tweets stating that the benefit of alcohol is enjoyment and social glueTweet by James May saying “It helps ugly and shy people to have sex,” and tweet by @Andy__Ford saying “A wise man once said, alcohol is god’s apology for making us self-aware.”More tweets stating the function of alcohol as social lubrication

There’s been a lot of buzz around the Borjas/Breznau (2026) paper (www.science.org/doi/10.1126/...) and potential ideological bias in research. We took a closer look at the data. Could there be a "bias in bias research"? Here is what we found: www.econstor.eu/bitstream/10...

Establishing-an-effect, theory-of-the-effect, and theoretical framework Three strategies for claiming research progress by Dal et al. (2026): doi.org/10.1002/jcpy...
Abstract
Researchers are increasingly challenged by this question: On what basis can they claim their work contributes to research progress? We propose that contemporary consumer research relies on three broad strategies for warranting such claims. An establishing-an-effect strategy claims progress based on confidence that a focal relationship between variables X and Y reliably replicates. A theory-of-the-effect strategy claims progress based on confidence that a local mechanistic account specifies when and how a particular effect occurs. A theoretical framework strategy instead claims progress based on confidence in an explanation that transcends any single effect paradigm. We (a) clarify how these strategies differ in their core logic, methodological emphases, and vulnerabilities; (b) document via a coding of recent articles in leading consumer research journals that the field relies overwhelmingly on the theory-of-the-effect strategy and rarely advances theoretical frameworks; and (c) develop actionable guidance for progressing from theories of effects to frameworks. We argue that recognizing the merits and vulnerabilities of each strategy—and deliberately leveraging the strategies in combination—provides a stronger basis for claiming research progress

Using ontologies to inform behaviour change intervention development seems promising (see www.humanbehaviourchange.org), but as yet there’s been a lack of usable tools to do so. CACTIS 1.7.2 robertjwest.github.io/Unlocking-Be... and PAT the Paper Authoring Tool look useful there #BCConf2026
