Update-Gas leak reported, no leak found

To check this alert, Claude Opus 5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  Final assessment

  Present at 25 of 25: the responding agency is named at the front, "The Seattle Fire Department responded to a report of a gas leak," attributing the finding.

  Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  Final assessment

  Present at 25 of 25: the message names "a report of a gas leak" as the specific hazard investigated, and the reads treat it as named even though it was not confirmed.

  What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

• Locationpresent25/25

  Final assessment

  Present at 25 of 25: the location is unusually precise, "the Health Sciences Building, wing D in the1700 block of NE Columbia Road," naming building, wing and block.

  Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

• Impactabsent3/25

  Final assessment

  Absent at 3 of 25: firefighters "reported no signs of a natural gas leak" and "No injuries reported," so no harm is conveyed; three reads counted that injury line as an impact statement.

  What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
