Suggested reading related to the topic: Smart & Sexy by R. Kaynes (https://www.amazon.com/Smart-Sexy-Evolutionary-Underpinnings-Differences/dp/1910524743 https://www.amazon.com/Smart-Sexy-Evolutionary-Underpinnings...) I wonder how he would comment this study... - higher IQ men are more likely to get married (because a higher IQ gives them an advantage hence they are more desirable to women), and higher IQ men earn more - married men have more pressure to dedicate their time and effort to provide for their family, hence they end up earning more - married men have more pressure and make different career choices to better provide for their family - this is a small leftover from a past, more conservative, more family oriented society (before women entered the workforce) which valued married men more (because more useful to society)
