Sexual market value and sexual selection
If we want to understand human behavior, and human opinions on many different topics, it is important to look at how behaviors and opinions affect the sexual market value of a person. This explains a lot of apparently altruistic and irrational behavior, especially in younger people.
Male teenagers may engage in extremely dangerous motorcycle races, and pretend that speed thrills, but in reality it is about impressing girls.
In wars, young men may be willing to die as heroes, if only to posthumously have a high sexual market value.
For females, it is the same. Women may force themselves into model roles that are contrary to their biological needs if they think it enhances their sexual eligibility.
Some people want to reap benefit from a high sexual market value. They indeed want to engage in sex. But for others, sex can become a theoretical quantity. If they believe that remaining virgins all life gives them the highest sexual market value, then they may just opt for this.
Noting the above-cited anachronisms isn't entirely new. Even Darwin had a hard time with phenomena like the beauty of male peacocks.
He explained it as sexual selection as an adjunct to natural selection.
But evolution, including the evolution of human behavior, has never been as logical as natural selection. Oftentimes, it looks more like accidental selection. And the results of accidential selection, in conjunction with sexual selection, prevail for a certain period of time, until something kills them off.
From a distance, natural selection seems linear. But for organisms as complex as animals, the shorter the observed time span, the more one sees irrational sexual selection at work.
