Blown Values is about a simple but uncomfortable idea:

Systems can produce results that look valid and convincing… while still being wrong in ways that aren’t obvious.

I came to this through pulmonary function testing, where small differences in technique, selection, and interpretation can shape results in consistent ways.

The challenge is that those results often look clean and clinically plausible, which makes distortion hard to recognize.

This publication explores how that happens—and how to see it more clearly.
