However, studies have found negative relationships between IQ and fertility in modern samples, though this negative relationship is generally more pronounced among women than men, which is broadly in line with evolutionary psychological predictions. This effect seems to be mainly driven by education rather than IQ per se, with more intelligent and thus generally more educated women delaying marriage & reproduction to focus on schooling, reducing highly educated women's lifetime [[reproductive success]] | However, studies have found negative relationships between IQ and fertility in modern samples, though this negative relationship is generally more pronounced among women than men, which is broadly in line with evolutionary psychological predictions. This effect seems to be mainly driven by education rather than IQ per se, with more intelligent and thus generally more educated women delaying marriage & reproduction to focus on schooling, reducing highly educated women's lifetime [[reproductive success]], which seems to be partly driven by women's shorter fertility windows and the greater tendency of highly educated women to be childless.<ref>https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/how-intelligence-affects-fertility-30-years-on-retherford-and-sewell-revisited-with-polygenic-scores-and-numbers-of-grandchildren/AB8EF68EE05C8DFD0A1C424B4FF7BC1F</ref><ref>https://www.pewresearch.org/social-trends/2010/06/25/childlessness-up-among-all-women-down-among-women-with-advanced-degrees/</ref> | ||
Another study found that among women, a one-standard-deviation increase in childhood general intelligence (15 IQ points) decreases their odds of parenthood by 21–25%.<ref>https://personal.lse.ac.uk/kanazawa/pdfs/SSR2014.pdf</ref> | Another study found that among women, a one-standard-deviation increase in childhood general intelligence (15 IQ points) decreases their odds of parenthood by 21–25%.<ref>https://personal.lse.ac.uk/kanazawa/pdfs/SSR2014.pdf</ref> | ||
