Ice storm closes campus for two consecutive instructional days

To check this alert, Claude (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.

• Sourceabsent8/25

  Final assessment

  Absent by majority: most reads hold that "Urgent Weather Advisory" is a label, not a named sender, and no university or agency signs the message; a minority read "Blacksburg campus" as identifying the issuer.

  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

  Unanimous that a weather hazard is present: an "Urgent Weather Advisory" with classes and activities canceled names a specific weather threat.

  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

  Unanimous that a location is named: "All Blacksburg campus".

  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.

• Guidanceabsent1/25

  Final assessment

  Absent by strong majority: it announces cancellations but gives recipients no protective action to take.

  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.

• Timepresent25/25

  Final assessment

  Unanimous that timing is present: it states the date "Tuesday Feb. 11, 2025".

• Impactabsent2/25

  Final assessment

  No; strong majority finds the winter-storm message states no hazard severity or potential harm, very few dissenting.

  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.
