On April 23, 2023, at approximately 12:00 AM, an MIT student reported that she was attacked from behind while entering her residence through the rear alley of the Delta Phi Epsilon sorority, located at 515 Beacon Street in Boston. According to report, the perpetrator initially approached the victim/survivor on a bicycle and asked for food. As the victim/survivor went to enter her residence, the perpetrator groped her from behind and then followed her into the residence, where he further assaulted her. The victim/survivor fought off the perpetrator and called 911. The perpetrator fled on a bicycle. The victim/survivor described the perpetrator as appearing to be a Middle Eastern male with dark curly hair, possibly a goatee, and riding a bicycle.

How the first alert is built

To check this alert, Claude Opus 5.5 (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.

    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.

    Final assessment

    Present, unanimously: it names a sexual assault in which the perpetrator groped the student from behind and further assaulted her.

    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.

    Final assessment

    Present, unanimously: it locates the attack at the Delta Phi Epsilon sorority, 515 Beacon Street in Boston, via the rear alley.

    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.

    Present, unanimously: it tells readers to program the MIT Police emergency number, use a Blue Light phone if threatened, and utilize SafeRide, which are protective actions.

    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

    Absent by a clear majority (22 of 25): the narrative describes the assault but states no injury or severity; a small minority read further assaulted her as conveying physical harm.

    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.
