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.

  • Sourceabsent0/25

    Final assessment

    Unanimous: no sender, agency, or branded signature is identified; the message only points recipients to purdue.edu for updates.

    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: "Shooting reported on campus" names the hazard.

    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

    Unanimous: "Bldg Electrical Engineering" gives the location.

    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: "Avoid area; Shelter in place" is explicit guidance.

    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

    Unanimous: no clock time, date, or recency marker is given.

    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 stated harm or severity beyond naming the shooting.

    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

Purdue's January 21, 2014 alert is a landmark in SMS-optimized campus emergency communication. The semicolon-separated format -- packing five distinct information elements into 120 characters -- became a model studied by emergency management professionals nationwide. The shooting itself was a targeted killing: student Cody Cousins shot and killed fellow senior and teaching assistant Andrew Boldt in the Electrical Engineering Building before surrendering to police outside. The Rave Alert platform reached approximately 83,000 contacts. Purdue's approach influenced the industry-wide shift toward terse, information-dense SMS alerts that dominated campus communication from 2014 until the gradual transition to multi-channel delivery made character limits less constraining.
Analysis

Key Findings

Semicolon-separated clause format maximizes information density within SMS constraints
120-character length fits within a single 160-character SMS segment
Five information elements (event, location, avoidance, shelter, URL) in one message, a design benchmark
83,000-contact distribution via Rave Alert, institutional-scale mass notification
URL redirect ('Check [t.co link] for updates') offloads detailed information to web
Outcome
One student killed in a targeted attack. Shooter surrendered immediately to responding officers.
