Suspicious device found at a campus-area intersection; all-clear in about 11 minutes

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.

• Sourcepresent17/25

  Final assessment

  A majority, 17 of 8, finds the sender present via the "IUB emergency" tag identifying Indiana University Bloomington; dissenters note it names the place but no issuing authority.

  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 that the hazard is named, "A suspicious device".

  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 find a location, "near 4th and Indiana".

  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 that guidance is given: "Avoid the area. Follow official instruction. Call 911".

  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

  Unanimous that timing 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.

• Impactabsent1/25

  Final assessment

  Absent by 24 to 1. The strong majority finds a suspicious device with an avoidance request states no explosive danger or harm; the lone dissent inferred potential explosive 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.
