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.

  • Sourceabsent0/25

    Final assessment

    S 0/25. The two sentences name no police unit, alert brand, or campus office as 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.

    See all 25 individual reads
    1. absent: No police department, alert brand, or named campus office appears in the two sentences.

    17. absent: Source fails because the notice never names an issuer.
    18. absent: Please find an alternate route is guidance, not a sender name.
    19. absent: The text hides origin: there is no branded signature or unit.
    20. absent: Without a named alerting office, Source cannot be coded present.
    21. absent: Due to a traffic accident still does not name who is speaking.
    22. absent: No public-safety agency is printed as the investigating or issuing unit.
    23. absent: A street name is not a source cue.

  • Hazardpresent25/25

    Final assessment

    H 25/25 majority present. Traffic accident is a specific named threat, not a generic incident or situation.

    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

    L 25/25 majority present. Fifth Avenue at Lytton Avenue names two streets as the place.

    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

    G 25/25 majority present. Please find an alternate route or allow extra time for travel is a protective instruction 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.

    See all 25 individual reads
    1. present: Please find an alternate route is a protective instruction to recipients.

  • Timeabsent0/25

    Final assessment

    T 0/25. The notice contains no date, clock, until, or 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.

    See all 25 individual reads
    1. absent: No date, clock, until, or now appears in the notice.
    2. absent: The two sentences never name a day, month, or year.
    3. absent: Traffic accident is the hazard, not a time cue.
    4. absent: Backed up is status, not a when word.
    5. absent: Alternate route carries no clock or date.
    6. absent: Immediately is also absent from the notice.
    7. absent: Time fails because the sentences contain no when cue from the rubric list.
    8. absent: There is no timestamp such as September 11 or 3:00 PM in the body.
    9. absent: Now is not written, nor is immediately.
    10. absent: Fifth Avenue and Lytton Avenue are places, not times.

    12. absent: Time is 0 because nothing in the wording answers when.
    13. absent: Without a date or clock, Time is absent even though traffic is described as backed up.
    14. absent: The text does not say now, so recency is not stated.
    15. absent: Clock time is missing, and no until bound is given either.
    16. absent: This product has no as of line and no today marker.
    17. absent: The body is undated; Time requires date, clock, now, or immediately.
    18. absent: Due to a traffic accident has no calendar stamp.
    19. absent: No weekday or clock time is given.
    20. absent: Time is absent because the message has no date, clock, now, or immediately.
    21. absent: The notice contains no date, clock, until, or now.
    22. absent: Nothing like Friday or a PM clock appears.
    23. absent: Extra time for travel is a duration of delay for the driver, not an incident clock.
    24. absent: Recency words such as now and recently are not used.
    25. absent: Without a calendar stamp or immediately, Time cannot be coded present.
  • Impactabsent0/25

    Final assessment

    I 0/25. Traffic accident is the hazard name, and no injury, dangerous, or serious-threat clause is added.

    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.

    See all 25 individual reads
    1. absent: Traffic accident is the hazard name, and no extra harm or injury wording appears.
    2. absent: Traffic is backed up restates congestion, not injury or dangerous language.
    3. absent: Alternate route is guidance, not a stated-harm clause.
    4. absent: Nobody is said to be wounded, killed, or in danger beyond the accident label.
    5. absent: There is no serious threat, injury, or dangerous clause separate from traffic accident.
    6. absent: Impact needs harm or severity beyond the hazard name, and this text does not supply it.
    7. absent: Backed up names traffic delay and does not add a consequence such as someone hit.
    8. absent: The sentences never say life-threatening, injured, or serious.
    9. absent: Hazard name alone is traffic accident; Impact requires more.
    10. absent: Extra time for travel is guidance, not extra impact.
    11. absent: No victim, injury, or continuing-threat sentence is attached.
    12. absent: Impact is absent because only the accident label is given.
    13. absent: Calling it backed up restates the accident effect and adds no injury clause.
    14. absent: There is no stated severity such as dangerous or serious threat.
    15. absent: I is 0 because the hazard name stands alone with no extra harm language.
    16. absent: Traffic accident without an injury or severity phrase is Hazard, not Impact.
    17. absent: Allow extra time is not injury language.
    18. absent: The notice does not say anyone was hurt or that the community is at risk.
    19. absent: Stated harm is required beyond the hazard name, and only the hazard name is here.
    20. absent: Impact is the stated harm, and this short form states none.
    21. absent: I stays absent: no consequence beyond the accident name is conveyed.
    22. absent: The product reports a traffic accident without adding dangerous or injury language.
    23. absent: No evacuate for your safety or similar severity cue is present.
    24. absent: Fifth Avenue and Lytton Avenue are location, not impact.
    25. absent: Without injury, deadly, or serious-threat wording, Impact does not ride along with the accident.
