Evolutionary psychologist David Buss speaks at The University of Southern Mississippi, on conflict between the sexes. The video of his talk is divided into 7 parts; all 7 parts of the video are below:
Research at the University of Abertay Dundee discovered that as women become more financially independent, they want an older, more attractive male partner.
Studies have previously found that women place greater emphasis on whether a man can provide for them, while men place more importance on good looks. The new study revealed that as women earn more and become more independent, their tastes actually change.
The finding suggests that greater financial independence gives women greater confidence in choosing their partner. Instinctive preferences for material stability and security become less important, physical attractiveness becomes more important, and the age of partner women pick also increases.
[M]ore financially independent women actually preferred even older men. We think this suggests greater financial independence gives women more confidence in partner choices, and attracts them to powerful, attractive older men.”
Oral sex is surprisingly rare in the animal kingdom. Humans do it, of course. As do bonobos, our close relatives. But now researchers have observed the practice for the first time in a non-primate. During intercourse, female short-nosed fruit bats lick the genitals of their partner, a possible ploy to increase copulation time. The discovery suggests there may be a biological advantage to fellatio.
The conclusion they are claiming…. Men usually like women that are “similar” to them, but when the men are stressed. they aren’t so picky in this respect.
Effects of stress on human mating preferences: stressed individuals prefer dissimilar mates

Although humans usually prefer mates that resemble themselves, mating preferences can vary with context. Stress has been shown to alter mating preferences in animals, but the effects of stress on human mating preferences are unknown. Here, we investigated whether stress alters men’s preference for self-resembling mates. Participants first underwent a cold-pressor test (stress induction) or a control procedure. Then, participants viewed either neutral pictures or pictures of erotic female nudes whose facial characteristics were computer-modified to resemble either the participant or another participant, or were not modified, while startle eyeblink responses were elicited by noise probes. Erotic pictures were rated as being pleasant, and reduced startle magnitude compared with neutral pictures. In the control group, startle magnitude was smaller during foreground presentation of photographs of self-resembling female nudes compared with other-resembling female nudes and non-manipulated female nudes, indicating a higher approach motivation to self-resembling mates. In the stress group, startle magnitude was larger during foreground presentation of self-resembling female nudes compared with other-resembling female nudes and non-manipulated female nudes, indicating a higher approach motivation to dissimilar mates. Our findings show that stress affects human mating preferences: unstressed individuals showed the expected preference for similar mates, but stressed individuals seem to prefer dissimilar mates.
Diane Witt, a researcher at Binghamton University, proposes that the release of oxytocin can be classically conditioned to the sight of certain people. Recall the Nobel Prize-winning Russian scientist Pavlov and his dogs. Dogs salivate when they are exposed to food–it plays an important role in the digestive process. Pavlov began ringing the bell every time he fed his dogs, and after a while the sound of the bell alone caused the dogs to salivate. The dogs had been classically conditioned to salivate at the sound of a bell. Witt believes that, in a similar way, oxytocin can be classically conditioned to be released by the brain with exposure to certain partners.
For example, a woman meets someone and on the first date she decides he doesn’t match up to her ideal–Clint Eastwood–but he’s still acceptable enough to date a few more times. Eventually she decides to have sex with him–and oxytocin is released, so she experiences that “oohhh so good” feeling. After having repeated sex, and oxytocin releases, with the same man, she forms a conditioned association. Pretty soon, just seeing the guy can cause her brain to release oxytocin–without even having sex. Suddenly “Mr. Acceptable Enough” becomes “Mr. Can’t Live Without.” Some researchers believe that prolonged attachment with a given person actually causes chronically high levels of oxytocin and its close hormonal relative vasopressin, which could feasibly help maintain long-term relationship bonds between women and men.
Of course, as Ron Guhname points out, she has to be “into you” in the first place.
People in most parts of the world do not think about their blood group much, unless they have an operation or an accident and need a transfusion.
But in Japan, whether someone is A, B, O or AB is a topic of everyday conversation.
There is a widespread belief that blood type determines personality, with implications for life, work and love.
Interest in blood type is widespread in Japan, particularly which combinations are best for romance.
Women’s magazines run scores of articles on the subject, which has also inspired best-selling self-help books.
The received wisdom is that As are dependable and self sacrificing, but reserved and prone to worry.
Decisive and confident – that is people with type O.
ABs are well balanced, clear-sighted and logical, but also high-maintenance and distant.
The black sheep though seem to be blood group B – flamboyant free-thinkers, but selfish.
The preoccupation with blood ultimately dates back to theories of eugenics during the inter-war years.
One study compared the blood of people in Taiwan, who had rebelled against Japanese colonial rule, with the Ainu from Japan’s northern island of Hokkaido, thought to be more peaceable.
Stripped of its racial overtones, the idea emerged again in the 1970s.
The article suggests that this blood type theory doesn’t have any evidence it support it.
Seems what different people consider “sex” seems to different.
When people say they “had sex,” what transpired is anyone’s guess. A new study from the Kinsey Institute at Indiana University found that no uniform consensus existed when a representative sample of 18- to 96-year-olds was asked what the term meant to them.
Is oral sex considered sex? It wasn’t to around 30 percent of the study participants. How about anal sex? For around 20 percent of the participants, no. A surprising number of older men did not consider penile-vaginal intercourse to be sex. More than idle gossip, the answers to questions about sex can inform — or misinform — research, medical advice and health education efforts.
Here are some of the results:
- Responses did not differ significantly overall for men and women. The study involved 204 men and 282 women.
- 95 percent of respondents would consider penile-vaginal intercourse (PVI) having had sex, but this rate drops to 89 percent if there is no ejaculation.
- 81 percent considered penile-anal intercourse having had sex, with the rate dropping to 77 percent for men in the youngest age group (18-29), 50 percent for men in the oldest age group (65 and up) and 67 percent for women in the oldest age group.
- 71 percent and 73 percent considered oral contact with a partner’s genitals (OG), either performing or receiving, as having had sex.
- Men in the youngest and oldest age groups were less likely to answer “yes” compared with the middle two age groups for when they performed OG.
- Significantly fewer men in the oldest age group answered “yes” for PVI (77 percent).
Frogs, salamanders, and other amphibians aren’t known as faithful lovers. They mate, then they scram. But researchers have now identified one species of poisonous Peruvian frog—Ranitomeya imitator—that has given monogamy a shot, the first amphibian known to do so.

What’s more, the frogs seem to be doing it for the kids: Limited resources keep them close to their offspring-and to each other-a condition that may have influenced the evolution of parenting strategies in other species as well.

On the surface, R. imitator and its relative R. variabilis, are quite similar. They look alike, sharing the same poisonous skin, ostentatious coloring, and compact, 20-millimeter-long body. They mate alike, with a loud and elaborate courtship. And, at least at first, they treat their young alike: After the female deposits her eggs on a leaf, the male fertilizes them, and, when the eggs hatch, he coaxes each tadpole onto his back and ferries it to a nearby pool.
But then the two species’ approaches to parenting diverge. R. variabilis moms hit the road immediately after mating, and while dads guard the territory around their young, they largely leave tadpoles to fend for themselves. In contrast, parent R. imitator frogs coddle their young. Once tadpoles are safe in individual leaf-pools, “the work has just started,” says Kyle Summers, an evolutionary ecologist at EastCarolinaUniversity in Greenville, North Carolina. About once a week for the next few months, the R. imitator dad calls the mother back to the pool so she can lay a nutritious egg for the tadpoles to eat.
Seems the trend is that, men benefit from being seen with an attractive woman and suffer from being seen with an unattractive one.
(One caveat I should add is that my impression is that what women tend to think makes an attractive/unattractive women is different than what men tend to think makes an attractive/unattractive women. Although, from reading this, it didn’t seem clear if this point was considered.)
Sigmund Freud famously confessed he had no idea what women want. Charles Darwin, however, had a hunch. He thought that women, like other creatures, want to propagate their genes. Where it gets interesting is how they figure out what kind of man to look for. Sure, most women like a man who is sincere and able to make them laugh, but the story gets more complicated. Women’s preferences vary over their menstrual cycle and whether they are looking for a short-term mate or a long-term partner, which, in turn, also depends on the time in the menstrual cycle. When looking for a short-term mate, women can use visual cues such as his shoulder-to-waist ratio, the angularity of his face, or the presence of facial hair. [...]
A woman looking for a good [long-term] man can use the old conformity heuristic. [...]
This is where choice copying in mate selection comes in. The basic idea is that females looking for a male partner are, in part, swayed by a male’s ability to attract other females. If this happens, if other women flock to some men just because other women do, two related phenomena familiar from folk psychology begin to make sense. First, as some men have noticed, their stock in the dating market paradoxically rises when they are committed; second, some women are concerned about losing their men to other, “raiding,” women.
[...] That’s the effect. A man who has been “validated” by another woman becomes more attractive. The effect is also specific. The desire to be friends with a man depends only slightly on an endorsement by another woman, and the expectation of being able to work with him as a colleague is not affected at all.
It would be interesting to see if there is any “structure” among women. Do some some exhibit this herding behavior more than others?
Also, on another note, I wonder if this has to do with why guys tend not to want others to know about less attractive girls they have had a “one night stand” with or “fool around” with.
An interesting paper from Eric D. Gould. Although not a surprising result. And shows there may be “some truth” to the claim that: men have built civilizations in order to impress women.
Marriage and Career: The Dynamic Decisions of Young Men
Eric D. Gould
Hebrew University, Shalem Center, Centre for Economic Policy Research, and Institute for the Study of Labor
This paper examines the extent to which human capital and career decisions are affected by their potential returns in the marriage market. Although schooling and career decisions often are made before getting married, these decisions are likely to affect the future chances of receiving a marriage offer, the type of offer, and the probability of getting divorced. Therefore, I estimate a forwardlooking model of the marriage and career decisions of young men between the ages of 16 and 39. The results show that if there were no returns to career choices in the marriage market, men would tend to work less, study less, and choose blue-collar jobs over white-collar jobs. These findings suggest that the existing literature underestimates the true returns to human capital investments by ignoring their returns in the marriage market.
