THE Washington Redskins, Manchester United and the Welsh rugby team have all been playing with an unfair advantage. Just seeing their red kit is seemingly enough to cow their opponents into submission even before a ball is kicked.
Russell Hill and Robert Barton of Durham University in the UK tracked success in four Olympic sports: boxing, taekwondo, Greco-Roman wrestling and freestyle wrestling. In these sports athletes do not wear national colours, but are randomly assigned either red or blue. Of 441 bouts, reds won 242 and in all four sports reds triumphed in more contests. And the red advantage was higher in close encounters: 62 per cent of red-garbed competitors won these. But in pushover contests there were similar numbers of red and blue winners. "If you're rubbish, a red shirt won't stop you from losing," Barton says.
