Editorial standards
The principles governing evidence selection, verification, publication, correction, and institutional transparency.
We prioritize primary documents, regulatory filings, audited reports, and reputable independent research.
Material claims must be traceable to a named source with publisher, date, and access information.
Names, dates, quantitative claims, and source links receive a separate verification pass before publication.
Material changes trigger documented review. Review dates remain visible on company and publication records.
Scores follow published criteria. Commercial relationships do not determine coverage or conclusions.
Substantive corrections are made promptly and preserved in the relevant version record.
Claims should be specific, proportionate to the evidence, and clear about uncertainty or conflicting information.
Methodology and publication changes are associated with dated releases so readers can understand what changed.
Impact500 distinguishes documented fact, analytical judgment, illustrative metrics, and future plans.
Corrections and questions
Readers may submit source updates, correction requests, or methodological questions to dshetty2498@gmail.com. Requests should identify the publication, claim, and evidence.
