Interpretation
Lifetime Sexual Partners Interpretation
This statistical patchwork quilt reveals a clear, if unsurprising, pattern: while the precise numbers differ wildly depending on who asks, how they ask, and who’s bragging, the consistent thread is that men reliably and often fantastically out-report women, creating a mathematical mystery of where all these extra partners are supposedly hiding.
