Being more [[life history|k-selected]], East Asians may be more sensitive to [[evolutionary mismatch]]es such as the absence of arranged marriage<ref>https://journals.sagepub.com/doi/full/10.1177/1474704919887706</ref> women's unusual high-status role,<ref>https://incels.wiki/w/Scientific_Blackpill_(Supplemental)#Women_were_historically_predominantly_involved_in_cooking_and_they_never_dominated_men</ref> overpopulation, or even the rise of mutations.

The graphs above for the overall U.S. population also point to a high rate of male Asian incels. Blacks having more sex, but fewer relationships compared to Whites may also be explained by racial differences in life history speed, so the graphs do not necessarily contradict each other. E.g. Blacks also have much higher rates of nonmarital births.<ref>https://commons.wikimedia.org/wiki/File:Nonmarital_Birth_Rates_in_the_United_States,_1940-2014.png</ref>
