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.
Weather alert: Our Corvallis campus will have a delayed opening until noon on Thursday, Feb. 13, due to expected inclement weather conditions. Classrooms and buildings will be closed and any events prior to noon on Feb. 13 are canceled, including Corvallis based classes. 🧵
Final assessment
Present, unanimous at 25 of 25. The "Weather alert" header plus "Our Corvallis campus" show the university speaking in its own institutional voice.
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.
Final assessment
Present, unanimous at 25 of 25. The closure is attributed to "expected inclement weather conditions", naming weather as the hazard behind the decision.
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
Present, unanimous at 25 of 25. The notice is scoped to "Our Corvallis campus", its "Classrooms and buildings" and "Corvallis based classes".
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.
Final assessment
Absent, with 0 of 25 finding guidance. The message announces a delayed opening and cancellations but never asks recipients to do anything protective.
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.
Final assessment
Present, unanimous at 25 of 25. A precise threshold is set twice: "delayed opening until noon on Thursday, Feb. 13".
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.
Final assessment
Absent, at 1 of 25. Nothing describes what the weather could do to people or property; the lone dissenter counted the closures and cancellations, which are schedule effects, not hazard 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.
