It's such a famous experiment that it even inspired a catchy song from the 90s: "Do you want to sleep with me?" From the British jazz-pop band touch and go.
It was the question that a group of students, men and women, asked strangers of the opposite sex, as part of a In the United States, 1978, the state-run experimental campus of Florida State University.
The results have caused astonishment: three out of four responded to the proposal. Instead, Not one woman accepted.
Interestingly, another of the questions that were part of the study – would you have an appointment with me? – Made very different results: about half of the consulted, both men and women, answered affirmatively.
The conclusions of the experts are overwhelming: the experiment clearly demonstrated the differences in male and female attitudes toward indifferent sex and Confirmed an ancient stereotype about the sexes.
For Canadian psychologists and writers Steven Puerer, this should not have surprised anyone.
"If you look at social phenomena, you see that people are more likely to be sexual harassers, to consume visual pornography, to hire prostitutes," he noted.
According to Pixer the experiment simply "Significantly confirmed a basic biological difference: … that a person can potentially be much more quickly than a woman. "
"When a woman becomes pregnant, she is nine to nine months pregnant, but a man can father as many children as there are couples ready to have sex with him."
"It is an asymmetry which is part of our anatomy"Picker talked." And it's not surprising that another part of our anatomy, our brain, reflects that difference ".
In summary, why Pinker and many other experts have said this is that when there is a risk of getting pregnant, the woman is much more careful when choosing a partner. He has no interest in indifferent sex.
Several subsequent studies suggest that reproducing the 1978 experiment achieved the same results, suggesting that there is no relationship with the time of the period.
One of the most recent experiments, conducted in Denmark in 2010, has shown that it has nothing to do with a possible US culture of purity.
That study shows the same results as always: Not a single woman agreed to have sex with a stranger, Against the majority of people.
It's even deepened by the fact that people are obsessed with sex: more people say yes to a sex crime with a stranger than those who agree to coffee coffee as a woman they don't know!
Another work carried out in Germany in 2015 changed the location of the experiment to a place counted more for an "ancestor" proposal: a disco.
But even there, the results of original experts from Hatfield and Clark remain intact.
Women and Sex
However, despite the fact that the exclusion of the experiment is indispensable – it is one of the few social studies that no one projects the results – some voices have emerged, especially female voices that they consider to be a misunderstanding.
These criticisms do not preclude the fact that the vast majority of women reject a stranger's sexual proposal. But they say that That doesn't mean they don't like casual sex.
They assure that the explanation of the results is not biological, however Culture.
In his book, "Bottom: How Science Got Women Wrong"Scientific journalist Angela Saini argues that they are the" Moral restrictions That dictate how a woman should behave the ones that explain female rejection to indifferent sex.
Seine objects to interpretations that remain only in these biological.
"(It's not right) to think that you can divide nature and nurture, its biological and cultural, and get to the root of what we really are," he told the BBC.
"What we really are social beings and you can't separate one thing from the other," he said.
Author, Author, "The woman who has never been Evolved"(" The woman who never evolved) agrees that it is the social that defines the attitudes of women to sex.
It emphasizes that, although in the last few centuries the wife was considering a much less sexual being than the person, this is not always the case.
"In some cultures women are afraid and have seen the devil and how ExcessiveiSexually The ancient Greeks compared women with bears and lions, suggesting that it was essential to keep them locked, "he says.
And although today the vision has changed a lot from the Victorian era, when psychologists believed that women do not have sexual desire, the fact that even in the 21st century and in the West, there are severe social restrictions when women try
This was confirmed by Terry Conley's psychologist, a subject on the subject in 2011. "Women are judged for sexual harassment Like people, and there is something that concerns them. "
Conley illustrates it with an example of modern life: the so-called "Pity"(Way of shame), as it is called when a woman comes to her house in the morning, dressed in her clothes from the previous night, after having had a casual meeting with someone.
"There are studies that show women Put your reputation at risk If you accept a proposal for sex, it can be considered a young or desperate sex. The person does not suffer from social damage, "says Cordelia Fine, author of" Testosterone Rex ".
Fine, a professor at the University of Melbourne, highlights another key element in understanding why all the women in the studios refused to have sex with a stranger: The fear of violence.
"What the experiments really showed is that women are not very interested in risking a situation where They can be killed quickly or can detect the potential of a potential harasser "He told the BBC.
Andreas Baranovsky and Heiko say, the German researchers who replicate the 1978 night-time experiment in 2015 – and found the same results wondering if women were offered a casual sex proposal in a way they did not have to fear, By its reputation or its physical integrity.
They developed a second experiment to reduce the fear factor: they asked a group of volunteers, men and women, to a laboratory on the pretext of helping a dating company evaluate its compatibility algorithm.
Ten images of the opposite sex are provided to them, and they are convinced that the ten have already agreed to meet them (either for an appointment or for sex).
The results are remarkable: There are almost no differences between the sexes.
The 100% of men and 97% of women They agreed to have an appointment with at least one of the candidates with the potential to have sex.
Another study conducted by Terry Conley reached similar conclusions.
Conley decided to use recognized figures – Hollywood stars – as potentially casual partners rather than strangers.
He asked a group of people if they would accept a sexual proposal from Angelina Jolie and a group of women if she would agree to have sex with Brad Pitt.
The majority of those consulted said yes.
The experiments asked the Catholic publications that the famous works of Hatfield and Clark had been celebrated for decades.
And they recommend that the image that many people have is conservative and do not like sex as much as men is wrong.
