Overview
- Researchers at the University of Chieti–Pescara reported the findings in Scientific Reports after testing the handedness–competitiveness link.
- More than 1,100 adults completed questionnaires to calculate a laterality quotient, followed by a focused sample of 483 strongly right-handed and 50 strongly left-handed participants.
- Left-handers scored higher on hypercompetitive orientation and were less likely to avoid competition due to anxiety.
- A lab-based 9-Hole Peg Test showed no dexterity advantage tied to handedness, with 11 of 24 right-handers performing faster.
- The authors discuss the fighting hypothesis and a minority-status mechanism as possible explanations, while noting the correlational nature of the results and the need for replication.
