On March, 19, 2019 at 4:25 p.m., the MIT Police responded to the Beta Theta Pi fraternity house, located at 119 Bay State Road on a report of a suspicious person. The reporting party stated that he encountered an unknown individual in the basement of the fraternity house and that the individual did not belong in the building. When confronted, the suspect fled the area and the reporting party followed the suspect to the first floor where he fled the building through the front door. The reporting party described the suspect as: Male, Black, 5'10", medium build, 50 years of age, black hair with specks of gray, wearing black clothing and carrying a blue draw string bag. Suggestions While victims of crimes are never to blame for criminal activity, there are some precautions that can be taken. In order to protect yourself and your belongings from theft and/or facilitate the recovery of your stolen property, MIT Police encourage you to follow these tips: - See Something - Say Something: Immediately notify the MIT Police at 617-253-1212 or 100 from any campus phone if you believe a crime is occurring, has occurred, or is about to occur. - Always lock your office and residential doors and windows. Assure that the locks are in good working order. - Lock your office or residential door if you are leaving (even if only for a minute or two). - When entering or exiting an office, make sure the door closes tightly behind you. - Report suspicious people or activity. Report all tailgaters. The MIT Police want to remind the MIT community that we are located in an urban setting and share many of the crime and safety issues that exist in any city. The MIT Police are investigating this crime and request the assistance from the MIT community. If you wish to leave an anonymous tip please call 617-258-TIPS (8-8477). Issued by Sergeant David J. O'Connor Crime Prevention/Community Policing Unit MIT Police 301 Vassar Street Cambridge, Ma. 02139 617-253-1212

How the first alert is built

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, 25 of 25. The place is named twice over: "the Beta Theta Pi fraternity house, located at 119 Bay State Road", basement and first floor.

    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.

    Final assessment

    Present, 25 of 25. The tips instruct readers to lock office and residential doors even for "a minute or two", to make sure doors close tightly, and to report tailgaters.

    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, 0 of 25. All reads note that the suspect "fled the building through the front door" with nothing taken, damaged or threatened, so no consequence or severity is conveyed.

    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.
