The sexual revolution happened when the pill happened, that is, when Hormonal Birth Control happened.
In the comments Spandrell provides compelling evidence that the effect of hormonal birth control on the sexual revolution was not very large.Â
Yet we have long had methods of birth control and early stage abortificants.ï¿½ Condoms are so ancient that males have evolved to dislike them.ï¿½ The sponge has been around for several hundred years, the cap
has been around for a hundred and eighty years, the diaphragm for a hundred and thirty years.ï¿½ The IUD has been around for eighty years, but was not perfected until about 1950 or so..
The sponge, the diaphragm, and the cap have the inconvenience that they have to be inserted before sexual intercourse and removed after a day or so.ï¿½ The greater convenience of the pill and the modern IUD could well be the cause of the sexual revolution.ï¿½ But the IUD was safe and convenient ten years before the pill, and we only got the sexual revolution after the pill.
The sexual revolution happened when the pill happened, fifty years ago, consistent with the conjecture that the pill interferes with some critical component of bonding.
Among the atheist, materialist, and reactionary pick up artist movement, it is generally believed that the monthly ovulation hormone surge and the resulting behavior change that happens during ovulation is intended by natural selection to promote paternity fraud.ï¿½ Now while paternity fraud is a big problem, in that any paternity fraud is a really bad thing, and the threat of paternity fraud undermines fatherhood and the family, the actual amount of paternity fraud is pretty small, (not nearly small enough, but small) so I am inclined to agree with Sunshine Mary that paternity fraud is unlikely to be the primary purpose of the hormone surge.
(Digressing, one of the easiest things we could do to promote family formation is ensure serious legal and social consequences for paternity fraud, comparable with those of rape, thereby reducing a potent threat, and encouraging better female behavior by authoritatively stigmatizing the worst female misbehavior.)
The blogger Sunshine Mary, whose wonderful blog “The Woman and the Dragon” has now sadly disappeared, seems to have had an ovulation hormone surge that was quite noticeable to herself, so probably bigger than most, and she believed, on the basis of her subjective experience, that the primary purpose of the hormone surge was to promote sexual bonding, to bind women to stick around with the father of their children, to promote, rather than destroy, the family, though she recognized it could easily work both ways.
Perhaps women are programmed to bond when they orgasm with breast manipulation of those extra sensitive breasts that they have at ovulation time.
Hormone based contraception suppress the monthly ovulation based hormone surge, making women quite noticeably less irrational, emotional and illogical at least twice a month, and perhaps for the entire month.ï¿½ Perhaps irrational, emotional and illogical is what we need in order to reproduce successfully.
My own personal experience and observation is consistent with the theory that females who are not on hormone based contraception tend to form strong bonds, and stick around, and females on hormone based contraception tend to move along after three or four years, but I don’t have enough anecdotes for them to be data.ï¿½ (For housework, on the other hand, I have enough anecdotes to tell you confidently that it is apt to be disastrous for men to do women’s work.ï¿½ For housework, I have enough anecdotes to be data.)
No one has ever examined the effect of the pill on female bonding.ï¿½ It needs scientific examination.ï¿½ The pill obviously, on casual observation, has a significant effect on female behavior. It affects their minds quite noticeably, and many men view that as a major benefit. ï¿½ No one, however, has ever attempted to measure behavioral side effects. How does family formation and marital stability compare between women who use the pill, and women who use other methods?
