Subpar Parks: America's Most Extraordinary National Parks and Their Least Impressed Visitors

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 Subpar Parks: America's Most Extraordinary National Parks and Their Least Impressed Visitors 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 4.
