Stanford AIMS is testing whether we can predict hidden AI-evaluation outcomes from sparse observations. The useful shift: benchmark strategy becomes uncertainty allocation. Run expensive tests where predictions are uncertain or consequential; estimate the rest: but validate calibration across new models and harnesses.

From Fragmentation To Integration - A Review Of Data–Model Integration In Land Subsidence Research
--
https://doi.org/10.1016/j.ancene.2026.100567 <-- shared paper
--
H/T @manonzero current drought conditions, increasing pressure on ecosystems, and ongoing climate adaptation challenges, land subsidence is receiving growing attention worldwide.
For anyone wanting to learn more about land subsidence, or get a refresher, [the authors] provide an overview of the processes involved, the ways it can be measured or estimated, the models used to simulate it, and how observations and models can be combined, [their] new [#openaccess] review paper [link above] may be of interest!
A central message of the paper is that understanding and managing land subsidence requires bringing these different sources of information together…”
--
“HIGHLIGHTS:
• Presents a comprehensive synthesis that unifies all major elements of integral land-subsidence research.
• Defines the methodological steps needed for full integration and positions them within the broader challenges posed by subsidence.
• Brings together and distills the key components of data, modelling, and integration into a coherent framework.
ABSTRACT: Land subsidence, the sinking of the Earth’s surface, is a multi-faceted hazard driven by both natural and anthropogenic factors, and poses significant risk to environments, ecosystems, and society. Despite decades of growing research output, substantial gaps persist between investigations on the diversity of causes, reflected in data and model insufficiency. These gaps hinder the understanding of the issue and impede the effectiveness of mitigation measures. Many studies have urged to include all identified subsidence processes acting in a single area in an integral framework, for which a complex analysis has not systematically been outlined before. Therefore, [they] focus here on bridging the gaps between various technical research disciplines involved. [They] stress the urgency for an integral approach that combines observations with subsurface information of all known subsidence processes in an area, and [they] appeal for utilizing them in physics-guided data integrations. Only then can all subsidence drivers be understood, and effective mitigation measures designed. [They] outline the elements for an integral approach in categorical tables and schematized figures, and [they] discuss the main opportunities and challenges in a stepwise workflow. Leveraging these opportunities naturally leads to more robust, scalable, and policy-relevant solutions and fosters a more sustainable future…”

@maudenificent the article I was looking for: “London: Estimated toxic air-related deaths drop by 40%“

Change can be made; Powerful influencers make sure only negative stories about positive change. Hence it’s “too hard”.

The 2025 Trevor Levere Best Paper Prize goes to the team of the paper "The drop and the metric system: how an unruly unit survived revolutions"
https://www.tandfonline.com/doi/full/10.1080/00033790.2026.2636886

This is really great news and is for an excellent paper that I highly recommend reading!

Working myself in an area that has at best non-standard measurement units (at worst, some people would argue, is not measurement at all), I found this very interesting.

Just came across this blast from the past (2013):
https://rdcu.be/e7TDY
- daily assessments
- ordinal data multilevel #measurement
- DIF analysis

Couched as a preliminary investigation and pilot study, the analytic approach still sets a bar reached rarely by studies with such data.
