How the first alert is built
To check this alert, Claude Opus 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.

Final assessment
Present, 25 of 25 unanimously. The message opens "IUB emergency", the Indiana University Bloomington branded alert prefix that identifies the sending system.
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
Present on a unanimous 25 of 25. "A person with a pistol reported" names a concrete armed threat rather than an unspecified emergency.
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
Present, 25 of 25. The report is pinned "near 1200 E 3rd St", a street address precise enough to orient recipients.
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
Present, 25 of 25 with no dissent. Two direct imperatives close the message: "Take safe shelter. Follow official instructions."
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.

Impactabsent5/25
Final assessment
Absent at 5 of 25. A minority read "No action has been taken with weapon" as calibrating danger, but the majority is right that it reports status and states no potential 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.
