In this article, we reflect on "farmer surveys" in three European countries. Exciting to be part of this meta-science exercise. We learned a lot about our surveys. Hopefully, others find this useful. Would not have been possible without the excellent lead of Thomas Slijper.

Just finished Annika Norlin’s “Colony.” It’s a captivating story about a journalist with burn-out who goes into the woods and encounters a strange commune of outsiders. Very fun to learn about all of their backstories and figure out what happened 🧩

Juli Zeh über Nachbarn, die AfD wählen: „Ich bin nicht der Heldinnen-Typ“ Viel wird geredet über die, die für die AfD stimmen, Schriftstellerin Juli Zeh lebt mit ihnen im Dorf. Ein Gespräch über Rechtspopulisten, Talkshows und durchtanzte Nächte.

Juli Zeh erklärt wieder, dass ihre Nachbarn keine Rechtsextremen sind. Und dass ist halt mal wieder vollkommen vorbei am Thema. Es ist nämlich total egal, ob die rechtsextrem sind oder nicht oder ob sie eigentlich die Demokratie gut finden, wenn sie mehrheitlich (51,x%) eine Partei wählen, die 1/7

Advancing Agri-Environmental Policy with Behavioral and Experimental Economics: Insights, Innovations, and Future Directions 

In recent years, behavioral and experimental economics have increasingly shaped agrienvironmental research by revealing how farmers navigate complex decisions. This article reviews key developments in three areas: behavioral insights into farmers’ social, temporal, and risk preferences and identities, norms, and motivations; experimental methods for assessing behavior and policy impacts; and methodological advances enhancing scientific rigor. We highlight contributions to more behaviorally informed agri-environmental policies, including nudges, participatory approaches, and innovative schemes. Looking forward, priorities include large-scale collaborative studies, stronger stakeholder involvement, and integrating behavioral evidence into policymaking, addressing challenges such as farmer fatigue, to design adaptive, effective, and legitimate policies.

We wrote an article explaining why you shouldn't put several variables into a regression model and report which are statistically significant - even as exploratory research. bmjmedicine.bmj.com/content/4/1/.... How did we do?
