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.

Harvard Alert Cambridge Police are reporting that an unidentified male on a bicycle just shot at another person on Sherman Street. The suspect is on a bicycle heading toward Garden Street. Please avoid the area and shelter in place.

    Final assessment

    All 25 reads find Hazard present because the text names that an unidentified male on a bicycle just shot at another person.

    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.

    Final assessment

    All 25 reads find Location present: Sherman Street, with the suspect heading toward Garden Street, plus avoid the area.

    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.

    All 25 reads find Guidance present: recipients are told to avoid the area and shelter in place.

    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

    All 25 reads find Impact absent: shot at another person names the hazard without deadly, dangerous, or other severity wording.

    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.
