Genetic dead end
A genetic dead end is someone who will never pass on their genes; applies to various nonsexual people. GDE is an abbreviation of "genetic dead end". It basically refers to someone who will never breed and pass on their genes; hence a dead end (stoppage) of one's genes. The GDE usually comes to their position after interacting with an alpha male. This alpha male kicks him out of the herd or flock, and he's too meek to reenter another one. The GDE's circumstance is sometimes reached because the females of his species are able to detect that he has low quality genes. In ethology-related forums, GDE's are described usually as male animals, since hypergamy is rife in the animal kingdom too.
Among humans, males are twice as likely to becomes GDE's than females. The leading (and seemingly only) cause for becoming a GDE among females is high IQ. Analyses of the National Child Development Study show that more intelligent men and women express preference to remain childless early in their reproductive careers, but only more intelligent women (not more intelligent men) are more likely to remain childless by the end of their reproductive careers. Controlling for education and earnings does not at all attenuate the association between childhood general intelligence and lifetime childlessness among women. One-standard-deviation increase in childhood general intelligence (15 IQ points) decreases women’s odds of parenthood by 21–25%. Because women have a greater impact on the average intelligence of future generations, the dysgenic fertility among women is predicted to lead to a decline in the average intelligence of the population in advanced industrial nations.
