Lightning forces mid-game stadium evacuation; first weather-canceled game in 128 seasons

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.

  Final assessment

  Unanimous: no sender or authority is named, only the hashtag '#GBR' and an unattributed 'we.'

  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.

• Hazardpresent22/25

  Final assessment

  A clear majority read 'lightning' as the named hazard behind the weather delay, even though the word appears mainly via context and emoji rather than being spelled out plainly; a minority felt this fell short of an explicit textual naming.

  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

  Unanimous: no specific place is named.

  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.

• Guidanceabsent0/25

  Final assessment

  Unanimous: the message only reports delay/resume status with no protective action instructed.

  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.

• Timepresent22/25

  Final assessment

  A strong majority found '30 minutes from the last lightning strike' sufficient to convey timing, though a couple of reads noted no clock time or date accompanies it.

  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.

• Impactabsent0/25

  Final assessment

  Unanimous: no consequence or severity is stated.

  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.
