Natural gas leak on 700 block of Atwater Ave

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, unanimous 25 of 25. The "IUB emergency" banner opens the text and identifies Indiana University Bloomington as the sender.

  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, 25 of 25. "Natural gas leak reported" names the specific hazard, a gas release, rather than a vague incident.

  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

  Present on all 25 of 25 reads. The leak is placed at "the 700 block of Atwater Ave", a specific block of a named street.

  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

  Present, 25 of 25 without dissent. Recipients are told to "Avoid the area" and to "Follow official instructions", both explicit protective directions.

  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.

• Timeabsent0/25

  Final assessment

  Absent, 0 of 25. The alert says the leak was "reported" but attaches no clock time, date or word signaling how recently that report came in.

  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

  Absent by unanimous 0 of 25. Explosion risk, fire and inhalation effects all go unmentioned; the message never says why escaping natural gas is dangerous.

  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.
