Phoned-in bomb threat evacuates downtown campus for about an hour; not credible

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 element is absent: no sender, agency, or branded signature identifies who issued 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 element is absent: it cites a public safety threat but names no specific 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

  All 25 reads agree the element is present: it names the Liston 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.

• Guidanceabsent6/25

  Final assessment

  A clear majority (19 of 25) finds the element is absent: most reads find that announcing we are evacuating describes the institution acting and gives recipients no direct protective instruction; a minority read it as implying recipients evacuate.

  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.

  Final assessment

  Nearly all reads agree (24 of 25) the element is absent: no clock time, date, or recency cue appears.

  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.

• Impactabsent4/25

  Final assessment

  Absent by a 21 to 4 majority. States a campus is being evacuated due to a public safety threat but states no specific harm or what the threat could do; the minority read evacuation as conveying danger.

  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.
