Message elements

How the first alert is built

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

    All 25 reads agree the sender is absent: the text says "Follow official instructions" but names no sender or branded signature.

    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

    Unanimous that the hazard is named, "Shots fired".

    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 find a location, "the area of Dunn and 17th 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

    Unanimous that guidance is given: "Take safe shelter. Lock door. Follow official instructions. Call 911".

    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.

    Final assessment

    Unanimous that timing is absent: no clock time, date, or recency cue appears.

    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 absent. All 25 reads agree it reports shots fired and gives shelter instructions but states no specific harm or danger to people.

    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.

About this analysis
Context

Background

Little 500, Indiana University's signature annual bicycle race weekend, is one of the largest student events in the country and draws tens of thousands of visitors to Bloomington each April. During the 2024 edition, two separate shooting incidents disrupted the festivities. The first occurred around 10:55 PM EDT on April 19 at an apartment on South Curry Pike, where a 56-year-old Bloomington man was shot multiple times; two suspects were arrested. Hours later, IUPD officers heard gunshots at approximately 12:42 AM EDT on April 20 near Dunn and 17th Street, close to campus. The IU Notify alert was activated directing recipients to take safe shelter, lock doors, and follow police instructions. Witnesses reported a male in a blue jersey firing rounds into the air; officers located spent shell casings but no victims or damage from the shots. An all-clear was issued at 1:12 AM EDT.
