Emailed library bomb threat closes libraries and nearby buildings; hoax all-clear

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

  Present by majority, 14 of 25 read it as present. The reads turned on the closing 'murraystate.edu/raceralert' link, treated as a branded institutional sender tag; a substantial minority held that a bare URL is not a signature naming 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.

• Hazardpresent25/25

  Final assessment

  Present, 25 of 25. The opening words 'Due to a bomb threat' name the hazard outright, leaving nothing for reviewers to dispute.

  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

  Present, 25 of 25. Every read pointed to 'the areas of Pogue and Waterfield Libraries' as named, specific places 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

  Present, 25 of 25. The instruction 'please avoid the areas' is a direct protective action, reinforced by the direction to visit the alert page for more information.

  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.

• Impactabsent0/25

  Final assessment

  Absent, 0 of 25 read it as present. The bomb threat is named but nothing states what it could do or how severe the danger might be.

  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.
