Lawnmower strikes a gas line at an apartment building; about 58 students evacuated

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.

• Sourceabsent5/25

  Final assessment

  Absent by a strong majority: no institution, agency, or branded signature names the sender. A minority argued the rowan.edu link and the collective We imply the university, but that is inference rather than identification.

  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.

• Hazardpresent25/25

  Final assessment

  Unanimous: the message states plainly that there is a gas leak, a specific named hazard.

  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

  Unanimous: the location is pinned to the Edgewood Park Apartments, Building 500.

  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.

• Guidancepresent25/25

  Final assessment

  Unanimous: recipients still inside are told to evacuate immediately and are pointed to a page for updates, a clear protective instruction.

  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.

• Timepresent25/25

  Final assessment

  Unanimous: the word immediately, together with still inside, conveys that the situation is current and urgent.

  When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

• Impactabsent12/25

  Final assessment

  Absent on a narrow split. Most reads found no stated consequence such as explosion or health risk, while a large minority held that promising to say when it is safe to return implies the building is presently unsafe.

  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.
