— The Professor
The Professor's Experiment is an elaborate multi-phase experiment that involves surveilling unwilling subjects and pushing them to their limits. The experiment began shortly after the murder of Beacon Heights University student, Nolan Hotchkiss. If the subjects refuse to comply they will be incarcerated for conspiracy to cover up a crime.
The experiment is currently navigated by The Professor.
Phase One appears to have been mostly surveillance on The Perfectionists, Alison DiLaurentis, and eventually Taylor Hotchkiss with the assistance of Jeremy Beckett. Beckett surveilled the group in order to protect Caitlin.
The professor would hack into Beacon Guard and other systems to spy on and threaten the group while seeing what they would do. They also made an encrypted list so that the system could pinpoint specific people which included Taylor Hotchkiss and Ray Hogadorn.
Jeremy tried to cover up his tracks and make a run for it but, everyone believing he killed Nolan, was shot by Taylor and The Professor caught it all in camera. With incriminating evidence against them, they decided it was time for phase two.
In a room with seven chairs, The Professor introduced the subjects to the experiment and ensured their compliancy by destroying Taylor's RV and personal Beacon Guard computer.
He also asked them to tell him their greatest fear for yet undisclosed purposes.
