The Challenge

Every model is wrong — so why trust them?

Climate models are the backbone of our understanding of Earth’s future. They guide decisions about infrastructure, energy, and adaptation that involve billions of dollars and countless lives. Yet every model is imperfect. This isn’t a dig at climate science; it’s a fact about the very nature of scientific models. Each one simplifies reality, leaving scientists, policymakers, and the public unsure whether to act on their results. The stakes could not be higher: how do we plan responsibly when the very tools we rely on are flawed?

My Work

Turning error and disagreement into engines of trust.

I investigate how climate scientists learn from imperfect tools — and how philosophy can make those practices clearer and more credible. My approach is naturalistic: I study real scientific practice through case studies, interviews, and collaborations with modeling teams. I highlight not only how models succeed, but also how scientists diagnose mistakes, refine methods, and sometimes even learn more from failure than from success.

Philosophy, in this sense, is not abstract wordplay: it is a critical companion to science, clarifying what scientists already do and probing its limits. For a deeper dive, check out the game below.

The Insight

Agreement builds confidence. Disagreement sparks discovery. Error drives progress.

My work calls for a change in mindset: trustworthiness does not require truth. Since all models are false in some respects, credibility must come from elsewhere — from patterns of agreement, from productive disagreement, and from the ability to learn through error.

Quote

All models are wrong. Some are useful — Stastician George Box (1976)

This shifts us away from a binary view — “perfect or useless” — and toward a more practical stance: models can be wrong and yet useful, flawed but still trustworthy.
