The Copycat Effect: How the Media and Popular Culture Trigger the Mayhem in Tomorrow's Headlines is a 2004 book by suicide researcher Loren Coleman.

Coleman criticizes mass media's coverage and representation of tragedies and violence, arguing it leads to more imitation cases.

The response to the book was mixed, with commentators praising its delivery and evidence, though others criticized its tone and title as misleading.

Coleman has a master's degree in psychiatric social work and was a consultant for the Maine Youth Suicide Program for nearly a decade.

[6] Publishers Weekly said the book presented Coleman's advice "with enough punch to intrigue the public and possibly exert a minor influence on the press", though noted "readers may feel there's little they can do to muzzle media destructiveness".
