Phoned threat to 'shoot up' campus prompts a six-hour lockdown; caller surrendered

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 in the message.

  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.

• Hazardabsent0/25

  Final assessment

  All 25 reads agree the hazard is absent; it gives lockdown actions without stating the threat.

  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

  All 25 reads agree the location is present, referencing the campus and the nearest room.

  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 go to the nearest room, turn off lights, lock the door, and remain quiet.

  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.

• Timeabsent3/25

  Final assessment

  Strong majority finds time absent; a few read until an All Clear is issued as a duration cue, but most see no clock time or date.

  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.

• Impactabsent2/25

  Final assessment

  Absent by a strong 23 to 2 majority. The alert gives lockdown guidance to stay away until an all-clear but states no specific harm or consequence the threat could cause.

  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.
