osteological paradox mistakes worst skeleton = best health
state” - J. wood
- mistake 1: unstable disease characteristics → we’ll never know how prevalent a disease is w/o stable demography which is impossible
- mistake 2: mortality selectivity → some diseases r age selective → more death in 1 age group, therefore overestimation of prevalence compared to acc society → sample bias
- mistake 3: variable sensitivity to disease → ppl respond diff to same disease → pops can be highly resistant, resistant, and weak → lesions only show up on resistant pop bc everyone else is dead (weak) or fully recovered (highly resistant)
