Residence or academic hall evacuated after rain-driven interior water leaks

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 by 19 of 25. The notice speaks institutionally and names "FM and SSC staff are on site" as the campus units handling it, though six reads objected that no alert brand or signature identifies a sender.

  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

  Present, unanimous at 25 of 25. The hazard is concrete: "water leaking inside" the building following "heavy rainfall earlier".

  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. "Wilson Hall has been temporarily evacuated" names the exact affected building, leaving no ambiguity about the place.

  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.

• Guidanceabsent0/25

  Final assessment

  Absent, 0 of 25. The message reports that the hall was evacuated and that staff are on site, but it never asks recipients themselves to do anything.

  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

  Present, 25 of 25. "heavy rainfall earlier", "currently closed" and reopening "tomorrow" fix the past, present and expected future of the event.

• Impactpresent15/25

  Final assessment

  Present by a narrow 15 of 25. The stated effect is that the hall is "temporarily evacuated and is currently closed" with "isolated areas that may be closed"; ten reads wanted injury or damage severity.

  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.
