See explanation for double standard in previous post. It has all to do with the problem of high levels of bastardy and resultant social pathologies.
Do you think our ancestors decided to control sexuality after they made formalized tallies and hit the books or because of their connection to real life and seeing female and male behavior up close and being aware of the effects of what some authors call “sexual anarchy”? And they didn’t have to turn to Yahweh, Odin, or Allah, to deal with reality right in front of their faces. (Hey Odin, it’s me. I noticed when we let all these alpha males hog all the women, we’re stuck with these bastards causing trouble all over the place! It causes social unrest, low trust, jealousy, and resentment, and we can’t take on large scale projects and get shit done! What should we do?!”)
I don’t know how anyone else here draws conclusions and makes life decisions, but I do not do so by utterly academic and cerebral means. The content Andrewgen and I provided here, flawed as it is, only confirms what saw in my life before I knew such content existed. And I still see it.
As far as what amounts to too many partners of a woman for considering marriage material, that’s up to individual men to figure out, if they care about this matter; some don’t at all, and have alluded or said that even a triple-digit count isn’t too high for such consideration.
If I were single, I’d use my instincts based on age, explanation, number of partners, behavior and life history in the same way people judge one another for any social dynamic. In the case of a nineteen-year old woman with three, even if these three were boyfriends, I’d skeptically think, because of observation of young women (as biased a crowd as it was) when I was a young man, “Oh, one of those,” simply because I was around young women who had boyfriend after boyfriend after boyfriend. But, as I said, if the woman seemed like a good woman and gave an explanation for this boyfriend dujour pattern I so frequently observed, I’d give her a chance.
I don’t need studies as a means superior to the alarm bells that go off in my head in dealing with men and women generally. They are useful to a degree but they’re not there for dealing with life. I have my sixth sense for that. For example, when starting a new job, simply by overhearing people and seeing how they behave, I can quickly tell, “this guy/gal is a shitbag; I’m likely going to have an issue with him/her and I’ll speak to him/her on a need-to-know basis, and that’s it!” The same instinct can be used in assessing who might be a suitable life partner.
Pardon me if this post was self-indulgent. I simply explained how I look at studies on social matters versus real life experience.
