Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (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.

Due to a motor vehicle collision, the bridge on West Cherry Rd is currently one lane. Expect delays and seek alternative routes.

  • Sourceabsent0/25

    Final assessment

    All 25 passes found S absent (0 present / 25 absent). No university, agency, or branded signature identifies 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.

  • Hazardpresent25/25

    Final assessment

    All 25 passes found H present (25 present / 0 absent). A motor vehicle collision is the specific incident.

    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 passes found L present (25 present / 0 absent). The site is the bridge on West Cherry Rd.

    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

    All 25 passes found G present (25 present / 0 absent). Recipients are told to seek alternative routes.

    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.

  • Timepresent25/25

    Final assessment

    All 25 passes found T present (25 present / 0 absent). Currently marks the one-lane condition as present now.

    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.

  • Impactpresent20/25

    Final assessment

    20 of 25 passes found I present (20 present / 5 absent). Majority treated Expect delays as a stated consequence; five dissenters read delays as inconvenience rather than harm.

    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.
