The Color of Victory? Rethinking the Power of a Blue Judo Uniform
Another study disputes the finding.Can an athletes uniform affect success?
A study of the mens judo competition at the 2004 Olympics in Athens suggested yes. In high-level judo matches, to differentiate between the contestants, one competitor is chosen to wear a white uniform, called a judogi, while the other wears blue. The study found that those in blue won more matches than those in white, and suggested, among other reasons, that the brighter blue had an intimidating effect, much as with some animals, red coloration is thought to be intimidating.
