More fear mongering from the Roissy blog...
The level of hyper vigilance the author suggests is ridiculous. What high status male would take all the time to monitor their girlfriend's cycle, and administer affection or criticism accordingly, in an attempt to dissuade her from cheating? Why be in a relationship in the first place if it causes you that much stress?
Not to mention, the study cited in that video is more questionable social science. The conclusions were based on the fact that the ovulating women in LTRs showed more skin and danced more provocatively...in a LABORATORY setting. What's more, they didn't measure the same stats at different times of the same woman's cycle to get an individual "baseline." The women that showed the most skin and behaved most sexually were probably by and large the most attractive women, as women with average bodies tend to cover up more. I believe there is truth to the notion that women are more sexual when ovulating, but this study is a piece of crap. There are numerous interpretations for those "results."
I think Roissy has SOME good ideas, but he projects WAY too much his own paranoia on his dating advice. He's kind of like the Glen Beck of dating advice, actually--living in his head and out of touch with reality.
Here's another example from the same author- "Chateau"--:

"I estimate 1% of all men and 2% of all women meet their soulmates. The reason for the discrepancy is that male soulmates are in shorter supply than female soulmates."
^^^It's always a pleasure to hear someone quantify an imaginary concept using scientific terms. Here's some more "advice" for maintaining a relationship:
"Have a threesome. Spend an inordinate amount of time admiring the labia of the other woman. Be sure to moan louder with her. WARNING: If you *** on the other woman you will have to spend weeks consoling your girlfriend."
^^^More advice that comes not from actual flesh-and-blood interactions, but from an overactive imagination.
The problem with the internet is that ANYONE can claim to be an expert when giving advice, and it's easy to imagine circumstances in which such advice would be effective when heeded. Similarly, you can easily corroborate ANY statement with "scientific" evidence. We all have our biases- myself included- so everything you read should be taken with a grain of salt.
