    Hell yeah! Hell no!

    blue gi FTW

    It turns out that blue gis are more likely to win...assuming the distribution of gi colors among competitors is random, which there are some doubts about due to how competitors are seeded into the blue and white slots, but all and all they have an interesting point.

    I remmber reading similar statistics in other sports, where red clad competitors were more likely to win...I'll try to dig out the article...

    So it's actually RED gi FTW!!!

    ========
    Psychology: Red enhances human performance in contests
    Russell A. Hill and Robert A. Barton

    Red coloration is a sexually selected, testosterone-dependent signal of male quality in a variety of animals and in some non-human species a male's dominance can be experimentally increased by attaching artificial red stimuli6. Here we show that a similar effect can influence the outcome of physical contests in humans across a range of sports, we find that wearing red is consistently associated with a higher probability of winning. These results indicate not only that sexual selection may have influenced the evolution of human response to colours, but also that the colour of sportswear needs to be taken into account to ensure a level playing field in sport.

    Helps to actually read the articles you copy from other forums:

    Corrigendum: Sporting contests: Seeing red? Putting sportswear into context

    C. Rowe, J. M. Harris, S. C. Roberts

    Nature 437, doi: 10.1038/nature04306 (2005)

    It has been drawn to our attention by David Matsumoto and Stephanie Hata that our first-round analysis of the Athens 2004 judo competition was biased by non-random allocation of blue judogis to a small number of seeded competitors. Although only 25 of 301 contests analysed are affected, the assumptions upon which those analyses were based were therefore incorrect. However, their reanalysis (D. M. and S. H., unpublished results), which excludes first-round matches, supports our conclusion that winning biases exist for male judo competitors wearing blue. Our interpretation of visibility-influenced winning biases therefore remains a valid and plausible alternative to that of Hill and Barton (R. A. Hill and R. A. Barton Nature 435, 293; 2005).

    Some of it could be scoring bias...

    Too bad there's so few blue gis at local tournaments, I'd do my own study...

    The red trunks sure didnt help Couture in his bout with Lidell.

    I think color means **** all and perhaps could only have a tiny impact if the fighters were dead even skill wise.

    I don't think there's a good statistics done on MMA yet.

    Actually, that's what the judo paper says (I think). The bigger the difference in scores (implied skill), the smaller the advantage for blue.
