Corrections
Help keep the record accurate.
Use the report link on a forecast’s version page, or identify an event below. A report records the issue for the operator; sending it does not change the published record.
How corrections work
Material forecast or source corrections are linked revisions. An official classification correction creates a new evaluation and updates dependent challenge scores. The original forecast, entrant universe, publication time and earlier evaluation remain available.
Reports use a daily rotating, hashed network identifier to limit abuse, without storing raw IP addresses in report records. Report text is retained as part of the private correction audit. It is never shown as public HTML.
