On the evening of 1 October 2026, a government maritime-security agency issued an advisory about the Strait of Hormuz. A tanker had been struck by an unknown projectile and was on fire.
A social media account relayed the advisory at 20:09 UTC, and that relay was the first report we collected. Over the next twelve hours, ten more reports from nine outlets carried the story in eight languages.
News agencies, regional media platforms and other accounts picked it up, some with background and some with only a headline. One added that the crew was safe, which was the advisory's own update. None had a second source.
How repeats become confidence
A system that counts outlets sees ten reports in eight languages and concludes the event is well confirmed. An analyst scanning a busy feed draws the same conclusion, and both are wrong for the same reason. Every report we collected traced to the one advisory.
Outlets repeat each other because repeating is faster than reporting, and at each step the attribution gets thinner. In the tanker case, six of the ten outlets named the agency behind the advisory, while the rest cited a report or nothing at all.
Counting outlets measures how far a statement has traveled, not whether it is true. The stories that spread fastest gain the most false confidence, and they are often the stories that matter most.
Count origins, not outlets.
What we published
We sent one warning from the first report. Its source note read: single-source at time of publication, based on one official advisory.
The ten later items were held back as repeats, so they did not reach the feed as ten more warnings or raise the warning's confidence. Confirmation comes from an independent source, not from another copy.
One story as it develops
The tanker fire was one chapter of a larger story. Our thread on it had opened two days earlier, on 29 September, with a commercial ship attacked in the Strait of Hormuz.
By 2 October the thread held 9 updates and 17 corroborations. The updates carried new facts, such as more vessels struck. The corroborations were later reports of what the thread already said.
Sent one by one, that is 27 warnings. Threaded, it is one story a reader can follow in order, with each new fact marked.
Count origins
Ask of each report where it came from, not how many places it appeared. Publish the first report and label it for what it is, then let the story grow when there is a new fact or an independent source.
Ten outlets carried one report. The honest number was one.
