Douglas Insights publishes quantitative research, and quantitative research sometimes contains errors. This policy explains what we treat as an error, how corrections are made and disclosed, and how to report a suspected problem in any Douglas Insights report, insight article or page.
What counts as a correction
A correction is a change made because something we published was wrong at the time of publication: a miscalculated figure, a mislabeled chart, an incorrectly attributed source, a factual error about a company or regulation, or a typo that changes meaning. Corrections are distinct from revisions. A revision updates a report because the market itself has moved since publication; revisions ship as new editions with a change log and are part of the normal publishing cycle, not this policy.
How corrections are handled
- Reported issues are reviewed by the Douglas Insights Research Team, normally within two business days.
- If the report was wrong, the figure or text is corrected in the published version and in the underlying model.
- The correction is recorded in the edition history shown on the affected report page, describing what changed and why.
- Buyers of an affected report receive the corrected files by email at no charge.
- Material corrections that could have influenced a purchase decision are additionally flagged to affected buyers directly.
What we do not do
We do not silently overwrite published figures, delete edition history, or remove pages to hide an error. If a report is withdrawn entirely, the page states that it was withdrawn and why.
How to report an error
Email [email protected] with the report name, the figure or passage in question and, if possible, the evidence that suggests it is wrong. Anyone can report an error; you do not need to be a customer. We credit reporters in the edition history if they wish.
