Understanding Corroboration Standard – Entity Authority

The minimum threshold for corroboration that maintains AI citation above the decay rate is the Corroboration Standard – Entity Authority: at least 5 Tier-1 or Tier-2 sources confirming each core entity claim, refreshed within the last 6-month training cycle window. Below this standard, corroboration contribution to citation probability deteriorates toward zero between training cycles.

Frequently Asked Questions

Why is the minimum set at 5 Tier-1 or Tier-2 sources?

This threshold has been validated as the minimum corroboration density that maintains AI citation probability above the natural decay rate between training cycles. Below this level, corroboration contribution deteriorates toward zero.

What counts as a Tier-1 versus Tier-2 source?

Tier-1 sources include academic publications, major news organizations, and government agencies. Tier-2 includes industry publications, professional associations, and regional news. The Source Tier Classification framework defines the full hierarchy.

How often must corroboration be refreshed?

Within the last 6-month training cycle window. Corroboration older than the window provides diminishing signal to the current training cycle and must be replaced with fresh citations to maintain the Corroboration Standard.
