The National Weather Service in Columbia has issued a tornado warning for the Univers

To check this alert, Claude Opus 5.5 (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

  Unanimous present: it states a "tornado warning" has been issued, a specific weather hazard.

  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 present: the warning covers "the University of South Carolina's Columbia 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.

• Guidancepresent25/25

  Final assessment

  Unanimous present: it tells people to "seek safe shelter immediately", move to an interior hallway on a lower level, stay away from windows, and "DO NOT use elevators".

  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 agree Impact is absent: the alert gives detailed sheltering steps but never states what the tornado could do or how dangerous it is.

  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.
