the claim

Left-handed people have an advantage in interactive sports such as fencing and tennis.

the verdict
CONTESTED PARTIAL
Recorded sources
5 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that left-handed people have an advantage in interactive sports such as fencing and tennis?

Partly. Evidence partially supports a left-hander advantage in some interactive sports: a 2025 study finds overrepresentation of left-handers in fencing and table tennis, and other sources report more left-handers among tennis players and a general sports advantage. However, a longitudinal study of elite tennis finds the left-hander advantage moderate, declining over time, and almost absent in female professionals, so the claim is only partly supported and contested.
