No, ‘One Flew Over the Cuckoo’s Nest’ is not a true story. It is a work of fiction written by Ken Kesey. The novel, published in 1962, is set in a psychiatric hospital and explores themes of individuality and rebellion against oppressive systems. While the story is not based on real events, Kesey drew inspiration from his own experiences working as an orderly in a mental health facility. The characters and events are fictional, but they reflect broader societal issues and the treatment of mental health patients during that time.
