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.

Hazardpresent25/25
Final assessment
All 25 reads find Hazard present because the text specifies a social media post that referenced school violence, a named threat rather than a generic 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.

Locationabsent1/25
Final assessment
A 24 to 1 majority finds Location absent: the Princeton Fizz channel is an online forum, not a building, street, or other geographic place. One read treats that channel as a location.
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.

Guidanceabsent10/25
Final assessment
A 15 to 10 majority finds Guidance absent: asking anyone with information to contact DPS is a tip request, not a protective action. Dissenters treat that contact line as an instruction.
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: calling the post concerning and mentioning school violence names the topic without stating danger, injury, or other consequences.
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.
