Library bomb threat canceled afternoon classes; student arrested days later

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

  Absent on all 25 reads, 0 of 25. The text begins mid message with "However", and no institution, office or alert brand names itself as the 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.

• Hazardabsent0/25

  Final assessment

  0 of 25. The excerpt speaks only of ensuring "continued safety and well-being" and never states what the threat itself is.

  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

  Unanimous 25 of 25: "on-campus activities" and "campus personnel" place the cancellations squarely on campus, even though no building is named.

  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.

• Guidanceabsent11/25

  Final assessment

  Absent on a close split, 11 of 25 present. Most reads treat "all classes and on-campus activities are canceled" as an announced decision, while dissenters counted the move to remote work as a directive.

  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

  All 25 of 25 cite the stated timing, with cancellations effective "as of 1 P.M., and for the remainder of the day".

  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.

• Impactabsent0/25

  Final assessment

  0 of 25. Safety is invoked in the abstract, but no potential harm, severity or consequence of the underlying threat is described.

  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.
