Tornado warning seek-shelter then resume activities

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, unanimously at 25 of 25. The message opens with the branded tag "ECU ALERT:", which identifies East Carolina University's alert system as the sending 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.

• Hazardpresent25/25

  Final assessment

  Present, unanimously at 25 of 25. "Tornado Warning in effect" names a specific, recognized severe weather 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.

• Locationabsent0/25

  Final assessment

  Absent, unanimously at 0 of 25. The text never says where the tornado threat applies: no building, street, area or even the word campus appears between the warning and the link.

  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

  Present, unanimously at 25 of 25. Recipients are told to "Seek shelter indoors immediately" and to "Monitor weather conditions", both direct protective actions.

  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

  Absent, unanimously at 0 of 25. The alert names the tornado warning and the action, but never states what a tornado could do, such as injure people or destroy buildings.

  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.
