Message elements

How the first alert is built

To check this alert, Claude (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.

Police are investigating a report of a person who has been injured in the area of 5100 College Avenue. Police are on scene and this is an active investigation. This is not related to the earlier reports of a brush fire.

  • Sourcepresent25/25

    Final assessment

    All 25 reads agree the source is present; the message names Police as investigating and on scene, the responding 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.

  • Hazardpresent23/25

    Final assessment

    Strong consensus, 23 of 25, that the hazard is present; the message reports a person who has been injured, with two reads finding that too generic.

    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 reads agree a location is given; the alert cites the area of 5100 College Avenue.

    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.

  • Guidanceabsent0/25

    Final assessment

    All 25 reads agree no guidance is present; the message describes an active investigation but directs no protective action to recipients.

    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.

  • Timepresent22/25

    Final assessment

    Majority, 22 of 25, find timing present via recency cues active investigation and earlier reports; three reads found those too vague.

    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, unanimous. Reports a person who has been injured at a specific location, an explicitly stated harm to a person.

    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.

About this analysis
Context

Background

On Halloween evening, October 31, 2024, a shooting occurred at the SDSU Transit Center trolley stop near 5100 College Avenue on the edge of the San Diego State University campus. A call about a man being shot came in around 4:38 PM PDT, and officers found a gunshot victim at the underground trolley stop. The shooting stemmed from an altercation between individuals not affiliated with SDSU. Two suspects were quickly apprehended, with the alleged shooter arrested by 5:44 PM PDT and a weapon recovered. Police then searched for a possible third suspect, asking campus occupants to remain indoors until approximately 8:02 PM PDT when the all-clear was issued. No SDSU students, faculty, or staff were involved or injured. All evening classes and Aztec Nights events were canceled for the remainder of the night. Students later raised concerns about campus safety in the aftermath of the incident.
