This study integrates, refines, and updates previous findings pertaining to positive ecologic (population-level) associations between intelligence and suicide prevalence across nations by using corrected and revised national IQ estimates and, further, a quality-of-human-conditions index, both recently published by Lynn and Vanhanen. Across a global 85-nation sample of sex-specific total suicide rates and a Eurasian 48-nation sample of sex-specific elderly suicide rates, these were positively associated with updated national IQ estimates. The associations were stronger for the general population than for elderly persons, independent of the quality of human conditions, and notedly stronger in exponential fitting of suicide rates with national IQ than in linear fitting, thereby indicating that shifts or differences in national IQ correspond to proportional, not absolute, changes in suicide rates. Implications of these findings and the question of generalizability of such associations to the individual level are discussed.
本研究通过使用林恩（Lynn）和范汉宁（Vanhanen）最近发表的经过修正和修订的国家智商估计值，以及进一步使用人类状况质量指数，整合、完善并更新了先前有关各国智商与自杀率之间积极生态（人口层面）关联的研究结果。在一个涵盖全球85个国家的按性别划分的总自杀率样本以及一个涵盖欧亚48个国家的按性别划分的老年自杀率样本中，这些自杀率与更新后的国家智商估计值呈正相关。这种关联在普通人群中比在老年人中更强，与人类状况质量无关，并且在自杀率与国家智商的指数拟合中比在线性拟合中明显更强，从而表明国家智商的变化或差异对应于自杀率的比例变化，而非绝对变化。本文讨论了这些研究结果的意义以及此类关联在个体层面的可推广性问题。
