Methodology

The Southpaw Index is based on published IsLeftHanded profile records. Handedness is classified as Yes, No, or Unknown using available public evidence and editorial review. High-confidence records rely on reliable public sources such as official bios, interviews, reputable reporting, or clear video/photo evidence. Unknown records are excluded from rate calculations unless explicitly noted. This report should be read as a public-figure dataset, not a population study.
