Some previous primate studies have found a positive correlation between male dominance and mating success when data from subadult males were included in the analyses. The information in this paper suggests that an unconscious bias may have been introduced when data on subadult males were included because of the lower dominance rank of these animals. Data from a study of rhesus monkeys on Cayo Santiago showed that subadult males mated significantly less than adults. Because these monkeys are not fully mature, data on them should not be used in any test for correlation between adult male dominance and mating success. The only significant correlation found for adult male mating success was an inverse one with relation to age. Based on behavioral data young, fully adult males have the best chance of fathering offspring regardless of their dominance rank.
一些先前的灵长类动物研究发现，当分析中纳入亚成年雄性的数据时，雄性的优势地位与交配成功率之间存在正相关。本文中的信息表明，纳入亚成年雄性的数据时可能引入了无意识偏差，因为这些动物的优势等级较低。对圣地亚哥岛恒河猴的一项研究数据表明，亚成年雄性的交配次数明显少于成年雄性。由于这些猴子尚未完全成熟，它们的数据不应被用于任何关于成年雄性优势地位与交配成功率之间相关性的测试。成年雄性交配成功率唯一显著的相关性是与年龄呈负相关。根据行为数据，无论优势等级如何，年轻的成年雄性生育后代的机会最大。
