How the first alert is built

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, 25 of 25. "Police are responding" and "Police continue to investigate" recur in every entry, attributing the messages and the response to the police 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

    Present, 25 of 25. The hazard starts as a "Robbery at Hitt Street Parking Garage" and is specified at 12:53 as "a reported carjacking at gunpoint" of a silver Nissan Sentra.

    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. The scene is given as "Hitt Street Parking Garage, 309 Hitt Street", a named garage with a street number, repeated across the updates.

    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 first message instructs "Stay away, or leave the area", and the following updates repeat "Stay away from area" while police investigate.

    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.

  • Impactabsent8/25

    Final assessment

    Absent, 8 of 25. The "at gunpoint" detail describes the offense but no consequence or severity for recipients is stated, and the close reports "no further ongoing threat". Eight reads read gunpoint as stated lethal risk.

    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.
