The three law's of behavioural genetics: “First Law: All human behavioural traits are heritable. Second Law: The effect of being raised in the same family is smaller than the effect of the genes. Third Law: A substantial portion of the variation in complex human behavioural traits is not accounted for by the effects of genes or families.” Beyond that though, the genetics of human fertility is pretty well understood. Here's a (now fairly old: from 2016) GWAS study on human reproductive behaviour: https://www.ncbi.nlm.nih.gov/pubmed/27798627 They show genetic correlations between reproductive traits and other behavioural traits in Figure 3. You might find it helps you develop an intuitive understanding. Happy to answer questions if you have any. |

Isn't "intuition" basically the opposite of "science"? Shouldn't we try to answer questions about the latter, not the former?
