Our mission

The narratives that move populations rarely arrive with their evidence attached. We exist to rebuild that chain — making it possible for researchers, journalists, educators, and the public to understand not just what is being said, but where it came from and why it matters.

What we are not

HSI is not a content-moderation tool, a surveillance system, or a political instrument. We study public rhetoric and influence at the level of narratives and patterns — with strict ethical guardrails against targeting private individuals.

Our principles

Evidence first

No conclusion is published without an intact, verifiable evidence chain.

Radical transparency

Our methods, taxonomy, and limitations are public and documented.

Public interest

We analyze public narratives — never harass individuals or amplify private harms.

Human in the loop

People review every published finding. Models assist; they do not decide.
