Summary
A non-conformist convict feigns insanity to avoid prison labor and is committed to a psychiatric hospital. He befriends fellow patients and clashes with the authoritarian head nurse Ratched, attempting to bring freedom and individual agency to the institutionalized community. His charisma and defiance gradually inspire the other patients to challenge the oppressive hospital system.

The calibrated figure is built from 859 reviewers whose rating history varies enough to place their own average. A broader pool of 908 reviewers with two or more reviews feeds the raw-average track instead. 2,405 other films from the 1970s form the cohort it is ranked inside.
How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where One Flew Over the Cuckoo's Nest lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against Films · 1970s (2,406 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 859.
