About the project
This project grew out of several lines of work that were each moving toward the same question. Here’s how they came together, and where we’re going next.
-
error-in-sciencePhilosophy and history of science on error, mostly in experiments -
opacityWhether complex models and AI can be understood, and explainable AI -
credibilityScience and technology studies of how modeling communities build trust -
ryanRyan O’Loughlin’s research and fieldwork -
mattMatthew Mayernik’s research on data, documentation and credibility -
ai-climateClimate science: model comparison, then AI weather and climate models
-
A philosopher sorts the errors that can creep into an experiment by the stage at which they arise. Hon 1989
-
Climate scientists start running their models through the same experiments so they can be compared: CMIP, the Coupled Model Intercomparison Project, still going three decades later. Meehl et al. 2000
-
A hypothesis is well supported only if it has passed tests likely to catch errors: the idea of severe testing. Mayo 1996
-
Computer simulations are called “epistemically opaque”: no person can trace every step from input to output. Humphreys 2004
-
Nineteenth-century microscopists turned a mistake, nerve fibers damaged by handling, into a test for identifying nerve tissue. An error became a tool. Schickore 2005
-
Parts of climate models become meeting points between field scientists and modelers, binding the two groups together. Sundberg 2007
-
Errors in computer models come from many sources: code bugs, approximations, data, and the choices built into the model itself. Parker 2008
-
Skeptics argue climate models are so tangled that no success or failure can be pinned on any one part. Lenhard and Winsberg 2010
-
Some systems don’t just survive shocks and mistakes; they gain from them. Taleb calls this antifragility. Taleb 2012
-
Failure is central to how science succeeds. Firestein 2015
-
Climate modeling is a social enterprise: its knowledge is built by teams and communities, not lone modelers. Winsberg 2018
-
Ryan begins interviews and site visits with climate scientists at NSF NCAR and NASA GISS.
-
Matt shows that metadata and documentation are how scientists record what they know about their data and models, including known limits and errors. Mayernik 2019
-
Explanations bolted onto AI models after training can mislead; build understandable models instead. Rudin 2019
-
CMIP shapes climate research, but what each team learns about its own model tends to stay with that team. Touzé-Peiffer et al. 2020
-
Model comparisons earn trust by coupling institutions (rules, governance) with data infrastructure. Credibility belongs to the community, not any single model. Mayernik 2021
-
Explainable AI arrives in climate science, but different explanation methods can disagree about the same model. Others ask what would make such explanations genuine. Mamalakis et al. 2022; Buijsman 2022
-
FourCastNet, an AI weather model, makes fast global forecasts. Pathak et al. 2022
-
Ryan shows that climate scientists can and do trace model errors to their sources, using physical reasoning, simplification and carefully varied reruns, answering the skeptics. O’Loughlin 2023
-
FourCastNet’s instability, which kept it to forecasts under ten days, is traced to math built for a flat map. Rebuilt for a sphere, it runs a year. Bonev et al. 2023
-
In applied data science work, errors become “a site of collaboration” that reveals and reshapes how people work together. Lin and Jackson 2023
-
Climate scientists publish guides for choosing among explainable-AI methods, a sign of how widely they’re now used. Bommer et al. 2024
-
Ryan and coauthors urge AI climate research to look beyond after-the-fact explanations, toward knowing which part of a model does what. O’Loughlin et al. 2025
-
An AI forecast model goes into operational use at ECMWF, Europe’s weather center, alongside its physics-based one. ECMWF 2025
-
Climate model developers describe debugging that resists standard procedures, aiming for models that are “good enough”. Proske and Melsen 2025
-
Pilot interviews at NSF NCAR. A first finding: scientists often avoid the word “error”, preferring “bias”, “limitation” or “statistical distinguishability”. Parker 2008 as the starting typology
-
Ryan identifies four kinds of antifragility in modeling: flexibility, new hypotheses, learning from error signals, and credibility won by overcoming failure. O’Loughlin, manuscript
-
Allchin argues for “negative knowledge”: knowing about errors, and how they were corrected, is knowledge too. Allchin 2026
-
These lines of work were all moving toward one question none had asked directly: how can errors, and the ways scientists handle them, make AI-driven science better?
-
The team forms: Ryan O’Loughlin (philosophy of climate modeling, Queens College, CUNY) and Matthew Mayernik (data and credibility, NSF NCAR), with an advisory board of philosophers, STS scholars and scientists.
-
The Alfred P. Sloan Foundation funds the project: two years, through 30 September 2028.
-
Interview plan finished and ethics approval (IRB) obtained.
-
The advisory board meets twice a year.
-
Interviews begin at NSF NCAR, the LEAP Center and NASA GISS, with document analysis alongside.

Using AI in another science? Collaborate with us
The questions
Understanding
When scientists diagnose why an AI model failed, what do they come to understand about the model, and what does that mean for explainable AI?
Antifragility
When do errors leave models and research communities stronger, not just repaired, and better off than immediate success would have?
Credibility
How do the ways teams diagnose, document and share errors build or erode trust in the science and data they produce?
- How do errors in AI-driven models contribute to or constrain scientific understanding, and what do practices of error diagnosis reveal about model explainability?
- In what ways do modeling communities develop antifragile responses to error, using failures to strengthen rather than merely repair their systems?
- How do errors and their management shape the credibility of AI-driven models and the social organization of modeling teams?
How we work
Interviews
20 or more people at each of NSF NCAR, the LEAP Center and NASA GISS: scientists, software engineers and data specialists.
Documents
Reports, papers, code repositories, issue trackers and dataset records, to see how errors get written down, or don’t.
Analysis
Bringing what we hear into conversation with philosophy of science and STS, to say when errors help science.
Workshop
Two days for philosophers, STS scholars and scientists to test the framework.
Take part
Come to the workshop
For philosophers, STS scholars and scientists, with funding for PhD students and early-career researchers. The call opens in February 2027.
Give feedback
Read our framework as it develops and tell us where it’s wrong.
Bring another science
Similar questions are arising in genomics, astronomy and beyond. If you work there, we’d like to compare notes.
Interviews are voluntary and confidential, and no one is named without their consent.
