Corrections policy

If you find an error, send the URL, the passage and evidence that can be checked. You do not need to share statements or personal financial information.

How corrections are handled

1. Identify the disputed statement, formula or link.
2. Compare it with the original source and example assumptions.
3. If a material error is confirmed, correct it and add an editorial note to the affected content.
4. The editorial date changes when content is reviewed, not because of an automated system update.

Spelling and formatting changes may be handled without a material correction note. No response time is guaranteed, and submissions containing personal data are not published.
