A book about institutions that avoid admitting error is a poor place to hide one. Any factual error inRegulated to Fail — a figure, a date, a source, a characterisation of what an organisation did — is recorded here, with the original wording alongside the correction, so that a reader holding a printed copy can see exactly what changed.

Corrections are listed separately from updates. An update is something that happened after the evidential cut-off of 14 August 2026. A correction is something this book got wrong.

Reporting an error

Please write to justin@obrien.vision. It helps to include the chapter and, where you have it, the source you believe is correct. Substantive corrections are made here first and folded into the next edition.

Recorded corrections

No corrections have been recorded for the first edition. This page will list them if and when they arise.

The policy simulator

The policy simulator is held to the same standard. Every number it uses is published with its source on the method page, and every change to the model is recorded there in the model changelog, with the version number it creates. Every result and every shared link records the model version it came from, so a link made before a correction says so when it is opened.

If you think the model is wrong — a figure, a source, an assumption outside what the evidence supports — please write to the same address, naming the assumption (each has an identifier on the method page). Errors are corrected in the next version of the model and listed below with what was wrong.

No corrections to the simulator have been recorded.
