Popping balloons mistaken for gunfire triggered lockdowns across multiple campuses

To check this alert, Claude (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.

• Sourceabsent0/25

  Final assessment

  All 25 reads agree the source is absent; no sender tag or named authority appears.

  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

  All 25 reads agree the hazard is present; it names an active threat on campus.

  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.

  12. present: It names "Active threat on campus" with "barricade", but specifically "Active threat" signals a threat though generic; "threat" plus barricade guidance, however no concrete hazard like shooter is named.

  15. present: "Active threat on campus" plus "barricade door & hide" signals an armed/active threat, a specific hazard.

• Locationpresent25/25

  Final assessment

  All 25 reads agree the location is present; it says on campus.

  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

  All 25 reads agree guidance is present; it tells people to barricade and hide, avoid windows, and run if there is an option.

  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.

• Timeabsent0/25

  Final assessment

• Impactpresent25/25

  Final assessment

  Present by unanimous agreement; it declares an active threat and instructs barricade, hide, and run, conveying an explicit danger to people on campus.

  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.
