Summary
Genghis Khan and the Making of the Modern World, by Jack Weatherford, is a 2004 nonfiction biography and memoir title. The catalogue files it under adult readers.
4 reviewers here rate with enough spread for a personal baseline to be measured, against 5 in the broader raw-average pool. The sample-size-adjusted percentile discounts a sample that size. Its in-cohort standing is measured against the other 386 books published in the 2000s.
How the score was built
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 Genghis Khan and the Making of the Modern World lands against every book we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — books published in the same decade, so a Victorian novel is judged against Victorian novels rather than against this year's releases. Ranked against 2000s books (387 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.
