The baseline for the populationâs percentage of left-handed people is around 10 percent, but in some societies that number is far greater. Among Venezuelaâs Yanomami tribe, about 5 in every 1,000 people are murdered yearlyâand about 23 percent of the population is left-handed. For the Eipo in Indonesia, the murder rate is 3 in 1,000, and theyâre about 27 percent left-handed. And then there are the people of Jimi Valley in Papua New Guinea, who have a murder rate of 5.4 in 1,000 and an above-average instance of left-handed people at 13 percent.
Aiming a pistol is easy even with a cross-dominant eye. Using the dominant eye with open sights. About 10% of all people are left-handed. About 30% of the population has a dominant left eye. In quite a few shooters, the left dominant hand is paired up with the right dominant eye, or the right hand and left eye. When shooting pistol, that mismatch is easily overcome by a slight shift of the head position. With rifles and shotguns, cross-eye dominance can be a problem.
