The Rainbow Fish

We compare the reviewers of this book against every other book those same people reviewed. Each rating is scored relative to the reviewer's own baseline, so a reader who gives everything five stars is measured against their own five-star habit rather than against a stranger's. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.

Global percentile

Where The Rainbow Fish lands against every book we rank.

In-cohort percentile

This title has no publication year on record, so it cannot be placed in a decade cohort. Undated books share one bucket, which makes the in-cohort figure the same comparison as the global one. Ranked against all ranked books (no publication year) (1,160 books).

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 book 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 6.
