Broken Windows Theory: The Evidence For and Against the Policing Strategy
James Q. Wilson and George Kelling's 1982 broken windows theory argued that visible disorder—broken windows, graffiti, public drinking—signals to criminals that an area is uncontrolled and invites serious crime. New York City's aggressive implementation in the 1990s coincided with a dramatic crime drop. Whether the theory actually caused the drop remains one of criminology's most contested questions.
Celebrity Worship Syndrome: The Psychology Behind Parasocial Relationships
Celebrity Worship Syndrome describes an obsessive preoccupation with a public figure that psychologists measure on a scale from casual interest to borderline-pathological fixation. Research links intense celebrity worship to poor mental health outcomes, identity diffusion, and vulnerability to financial exploitation—yet mild parasocial relationships appear to be psychologically universal and largely benign.
