Message elements

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. The alert names both "The Ann Arbor Police Department (AAPD)" and the "U-M Division of Public Safety and Security," so the issuing and investigating authorities are unmistakable.

    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 heading "Crime Alert 2021-2: Aggravated Assault" plus two narrated attacks, punching and a grabbed throat, name the threat precisely rather than in general terms.

    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. Two specific places are given: "Nickels Arcade, the covered shopping district between State St and Maynard" and "the area of Catherine near Division."

    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 "Remember" list gives direct protective instructions: "Walk with a friend or co-worker in well-lit areas," "Avoid isolated areas," and "call 911 from any phone."

    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

    Present, 25 of 25. Each incident carries a clock time, "At approximately 10:00 p.m." and "At approximately 4:00 a.m.," which reviewers read as explicit timing of the events.

    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.

  • Impactpresent25/25

    Final assessment

    Present, 25 of 25. The suspect "punched the victim in the face and grabbed her throat," which reviewers uniformly read as a plain statement of the bodily harm at stake.

    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.
