Test case - north chapel hill sirens 2

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, unanimous at 25 of 25: "The University will TEST the Alert Carolina Emergency Notification System" plus the alertcarolina.unc.edu reference identify the sender beyond doubt.

  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.

• Hazardabsent2/25

  Final assessment

  Absent by 2 of 25: no hazard exists on Sept. 10, 2025; the bullets set out when sirens would be used. Two reads counted the listed armed person, hazmat and NWS tornado categories as hazards.

  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, 25 of 25: the audience is those "outside on or near campus", and "the Chapel Hill-Carrboro area" is named in the tornado bullet.

  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.

• Guidancepresent21/25

  Final assessment

  Present by 21 of 25: the notice tells readers to "review the Carolina Ready website and the Emergency Management and Planning website for information on what to do during an emergency", a real directive alongside the no-action line.

  The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

• Impactabsent3/25

  Final assessment

  Absent by 3 of 25: the text is procedural, listing notification types, and never says what harm could follow. A minority read severity into the "immediate safety or health threat" phrase.

  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.
