Gas leak near the Life Sciences building prompts evacuation of three buildings

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.

• Sourceabsent0/25

  Final assessment

  All 25 reads agree the source is absent; no sender tag or named authority appears in this update message.

  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 reads agree the hazard is present; it names the gas leak that prompted the evacuations.

  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 reads agree the location is present, citing the Logan campus and the affected buildings.

  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.

• Guidanceabsent2/25

  Final assessment

  Strong majority finds guidance absent; this is an all clear that classes are resuming, with no protective action for recipients, though a couple read the resumption as an implicit instruction.

  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.

• Timepresent16/25

  Final assessment

  Majority finds time present; Update, all clear, and present tense resumption read as recency cues, though a sizable minority sees no clock time or date.

  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 read: an all-clear stating evacuated buildings are cleared and open after a gas leak conveys resolution, not any stated harm or danger.

  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.
