Lesson · Algorithmic & Information Resilience
How Feeds Distort Hazard Signal
Why engagement ranking systematically favours dramatic and early claims over corrected ones, what that does to a community during an unfolding event, and how to build an information path that does not depend on a feed.

Learning objectives
- Explain how engagement-based ranking selects for emotional intensity over accuracy.
- Describe why corrections propagate more slowly than the claims they correct.
- Identify the conditions under which a feed is actively harmful during an event.
- Construct an information path that does not depend on algorithmic ranking.
In the field
Ordered, and meant to be workable under pressure. Numbered because the sequence matters.
- Subscribe directly to the issuing agency’s own channel before an event, not during one.
- Set up one non-algorithmic alert path such as SMS, radio, or email from the authority.
- Agree with your household which single source settles a disagreement.
- When you find a correction, send it directly to whoever you shared the original with.
- Keep a battery radio and know the frequency, for when the network itself is down.

The tag under each source states what was actually checked. “Authority named · URL not re-resolved” means the issuing body and document are named, but the link was not re-resolved for this lesson. It is not a claim of verification, and the authority’s own current bulletin always supersedes anything here.
