进化理论预测，雄性会为那些不太可能是它们实际后代的假定后代提供较少的父母投资。跨文化，亲子关系的信心（一个男人的可能性，他是一个假定的孩子的父亲的评估）是积极的男性参与与儿童和投资或继承父系亲属。一项对67项报告非亲子关系的研究的调查表明，对于具有高亲子关系的男性，非亲子关系的置信率通常为1.9%（不包括未知方法的研究），远低于许多研究人员引用的10%或更高的典型比率。亲子关系和亲子关系信心之间的关系的进一步跨文化调查是必要的。
Evolutionary theory predicts that males will provide less parental investment for putative offspring who are unlikely to be their actual offspring. Cross-culturally, paternity confidence ( a man's assessment of the likelihood that he is the father of a putative child) is positively associated with men's involvement with children and with investment or inheritance from paternal kin. A survey of 67 studies reporting nonpaternity suggests that for men with high paternity confidence rates of nonpaternity are( excluding studies of unknown methodology) typically 1.9%, substantially less than the typical rates of 10% or higher cited by many researchers. Further cross-cultural investigation of the relationship between paternity and paternity confidence is warranted.
