Cook County tornado warning with take-shelter instruction

To check this alert, Claude Fable 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.

• Sourcepresent25/25

  Final assessment

  All 25 passes found the source present, the issuing authority named at the message's opening, "#NWS has issued a #Tornado Warning".

  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

  All 25 passes found the hazard present, the threat is explicit and specific, a "#Tornado Warning".

  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

  All 25 passes found the location present, the affected area stated as "the Chicago Metro Area".

  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

  All 25 passes found guidance present, citing multiple protective instructions, "Seek shelter immediately" and "Move indoors and to a basement or other interior room on the lowest level".

  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.

• Impactabsent1/25

  Final assessment

  24 of 25 found impact absent, since the message names the tornado and orders sheltering but never states what the storm could do; only 1 of 25 read "Do not remain in open spaces" as implying life-safety risk, and the consensus treats that as guidance, not a consequence statement.

  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.
