The Science of Engineering Incidents and Identity: Why It's Rarely the Villain's Fault

"Who broke prod?" feels like the right question after an outage. Systems research gives a less satisfying but far more useful answer: complex systems fail through the alignment of many small conditions, not through one reckless actor (Reason 1990; Google SRE 2016). Meanwhile the people most responsible for keeping those systems alive — the ones doing infrastructure work, on-call rotations, and glue work — are systematically under-credited (Champion et al. 2024). And now a new identity threat layers on top: AI tools that promise to replace engineers are trusted by a shrinking minority of developers (Stack Overflow 2025). The old script — 'someone here is the villain' — is almost always the wrong read.
