Research results that left-handed people are `` excellent in fighting ability ''
Of the left and right hands, the 'left-handed' who has the dexterity and athletic ability is the left-handed, which is about 10% of the total population, a minority compared to the right-handed. Meanwhile, as a 'merit of left-handed', research results were announced that ' left-handed people are excellent in combat ability '.

According to research on weapons and tools excavated from archeological sites, the ratio of human dominant hands has not changed significantly from the state of 'about 90% right-handed and about 10% left-handed' for about 5,000 years, It has been shown that left-handedness is a combination of environmental and genetic factors . But we don't know about the 'left-handed advantage' that explains 'why left-handedness exists'. Meanwhile, in 1996, a hypothesis was proposed that 'left-handed people may have superior fighting abilities.'
The basic logic of this hypothesis is that `` right-handed people have little experience with left-handed people, but left-handed people have a lot of experience with right-handed people, so left-handed people are good at fighting '' . If this logic is correct, left-handed people with good fighting abilities are more likely to survive, so the percentage of left-handed people may gradually increase. However, this hypothesis states that 'many weapons and tools are for right-handed people, and left-handed people use' right-handed weapons / tools ', which increases the injury rate. Therefore, the ratio of left-handed people stabilizes at 10%.' Is explained.
Thomas Richardson and Tucker Gilman of the University of Manchester's School of Global Environmental Science tested the hypothesis. They studied the 'left-handed rate' of more than 13,800 male professional boxers, 1314 female professional boxers, and 2,100 professional mixed martial artists. As a result, it turned out that about 17% of male professional boxers, about 12.5% of female professional boxers, and 18.7% of professional mixed martial artists were left-handed. They state that the proportion of left-handed professional martial artists is statistically significantly higher than the typical rate of 10%.
Also, by investigating the match results, they found that 'left-handed professional fighters have a high win rate.' Studies show that left-handed male professional boxers have a win rate of 52.4%, left-handed female professional boxers have a win rate of 54.5%, and left-handed professional mixed martial artists have a win rate of 53.5%. The two commented, 'The winning rate of left-handed professional fighters is statistically significantly higher.'
`` This study shows that left-handed people not only account for a larger percentage of professional fighters, but also have a higher win rate, '' said Psychology Today , a scientific media report on the study. This suggests that superiority in combat may be one of the 'reasons for left-handedness'. '
