Corrections & revisions
A practice that publishes its methodology has to publish what happens when the methodology fails. This page is that commitment, written down before it is needed.

Two different events
When a number under a published conclusion changes, one of two things has happened, and they are not the same. Either Kakde Research changed its analysis — an error in reasoning, transcription or method, which is a correction — or the underlying source revised historical data, which is a source-data revision: the analysis was faithful to the vintage it used, and the world’s statistics moved underneath it. Both are recorded. Only the first is an apology.
How published work is versioned
As papers are published online, each carries a Published date and, where the work has materially changed, an Updated date with a version note. A correction is labelled Correction, with what changed and why. A source-data revision is labelled Source-data revision, naming the old and new vintages. Cosmetic edits — typography, layout, link maintenance — are not versioned events.
No corrections have been required to date; when one is, it will appear here and on the affected page.
What triggers a correction
A reader challenge that survives checking. An internal re-derivation that fails. A methodology error found after publication. Challenges are welcome and are treated as free peer review: the methodology is published precisely so that a reader who disagrees with a conclusion can see which number, or which assumption, to attack — and inquiries@kakderesearch.com is where to send the attack.
How the data itself is sourced, transformed and revised is covered by the sources & data policy.
