Black Belly of the Tarantula
Two parallel scores from 54 z-qualifying reviewers and 54 raw-average reviewers. Cohort: Films · 1970s (2,406 peers).
Z-normalized corrects for reviewer bias (every reviewer re-centered onto their personal scale). Raw average uses simple mean across the broader pool including stddev=0 reviewers. The 18-point gap is the rating-inflation signature for this title — discriminating reviewers liked it more than the casual crowd.
