Editorial direction

Not a Fact Anymore is an independent, non-commercial information project documenting scientific and historical claims that were once accepted, taught, or defensibly presented as fact and were later corrected, narrowed, reclassified, superseded, or overturned.

The project aims to provide a source-based, neutral account of how factual and scientific understanding changes over time.

The site contains no advertising, affiliate links, subscriptions, paid services, donations, sponsorships, or commercial partnerships.

Behind the project

Isaac Mattoo

Creator and editor

Isaac Mattoo

This is a personal project built around a simple idea: facts have histories, and the interesting part is often not merely that something changed, but how and why it changed.

The catalogue is curated, source-driven and open to correction. Its purpose is not to mock older ideas, but to document the process by which better evidence changes what can reasonably be treated as knowledge.

Not a Fact Anymore documents how defensible knowledge changes when stronger evidence arrives.

Every entry is dated, sourced, and open to correction.
