In a nation sample of 75 countries around the world, higher suicide rates of the total male, and female population corresponded to higher levels on the superordinate K factor from differential K theory, thought to reflect a set of mutually interrelated life history and reproductive strategy traits. Countries ranking high on suicide rates concurrently ranked high on national intelligence estimates, longevity, and affluence, whilst low on rates of births, infant mortality, HIV/AIDS, and crimes (rape, serious assault, and homicide). These findings integrate previously reported positive population-level associations between suicide rates and cognitive ability variables into the conceptual space of differential K theory. The propensity toward suicidal behavior is a positive correlate of the K superfactor.
在一项对全球 75 个国家的全国性样本研究中，较高的男性和女性总人口自杀率与来自差异 K 理论的上级 K 因素的较高水平相对应，这被认为反映了一组相互关联的生活史和生殖策略特征。自杀率排名较高的国家在国家智力估计、长寿和富裕方面排名较高，而在出生率、婴儿死亡率、艾滋病毒/艾滋病和犯罪（强奸、严重攻击和杀人）方面排名较低。这些发现将之前报道的自杀率与认知能力变量之间的积极人口水平关联整合到差异 K 理论的概念空间中。自杀行为的倾向与 K 超因素呈正相关。
