Five percent QUOTES

1 " You don't want him," she said to the pink-haired girl. " He has syphilis." The girls stared. " Syphilis?" " Five percent of people in America have it," said Ty helpfully." I do not have syphilis," Mark said angrily. " There are no sexually transmitted diseases in Faerieland!" ”Sorry," Jules said. " You know how syphilis is. Attacks the brain. "

2 " In the statistical gargon used in psychology, p refers to the probability that the difference you see between two groups (of introverts and extroverts, say, or males and females) could have occurred by chance. As a general rule, psychologists report a difference between two groups as 'significant' if the probability that it could have occurred by chance is 1 in 20, or less. The possibility of getting significant results by chance is a problem in any area of research, but it's particularly acute for sex differences research. Supppose, for example, you're a neuroscientist interested in what parts of the brain are involved in mind reading. You get fifteen participants into a scanner and ask them to guess the emotion of people in photographs. Since you have both males and females in your group, you rin a quick check to ensure that the two groups' brains respond in the same way. They do. What do you do next? Most likely, you publish your results without mentioning gender at all in your report (except to note the number of male and female participants). What you don't do is publish your findings with the title " No Sex Differences in Neural Circuitry Involved in Understanding Others' Minds." This is perfectly reasonable. After all, you weren't looking for gender difference and there were only small numbers of each sex in your study. But remember that even if males and females, overall, respond the same way on a task, five percent of studies investigating this question will throw up a " significant" difference between the sexes by chance. As Hines has explained, sex is " easily assessed, routinely evaluated, and not always reported. Because it is more interesting to find a difference than to find no difference, the 19 failures to observe a difference between men and women go unreported, whereas the 1 in 20 finding of a difference is likely to be published." This contributes to the so-called file-drawer phenomenon, whereby studies that do find sex differences get published, but those that don't languish unpublished and unseen in a researcher's file drawer.

3 " Herbenick invited me to sit in on the Human Sexuality class she was about to teach, one of the most popular courses on Indiana’s campus. She was, on that day, delivering a lecture on gender disparities in sexual satisfaction. More than one hundred fifty students were already seated in the classroom when we arrived, nearly all of them female, most dressed in sweats, their hair pulled into haphazard ponytails. They listened raptly as Herbenick explained the vastly different language young men and young women use when describing “good sex.” “Men are more likely to talk about pleasure, about orgasm,” Herbenick said. “Women talk more about absence of pain. Thirty percent of female college students say they experience pain during their sexual encounters as opposed to five percent of men.”

The rates of pain among women, she added, shoot up to 70 percent when anal sex is included. Until recently, anal sex was a relatively rare practice among young adults. But as it’s become disproportionately common in porn—and the big payoff in R-rated fare such as Kingsman and The To Do List—it’s also on the rise in real life. In 1992 only 16 percent of women aged eighteen to twenty-four said they had tried anal sex. Today 20 percent of women eighteen to nineteen have, and by ages twenty to twenty-four it’s up to 40 percent. A 2014 study of heterosexuals sixteen to eighteen years old—and can we pause for a moment to consider just how young that is?—found that it was mainly boys who pushed for “fifth base,” approaching it less as a form of intimacy with a partner (who they assumed would both need to be and could be coerced into it) than a competition with other boys. Girls were expected to endure the act, which they consistently reported as painful. Both sexes blamed that discomfort on the girls themselves, for being “naïve or flawed,” unable to “relax.” Deborah Tolman has bluntly called anal “the new oral.” “Since all girls are now presumed to have oral sex in their repertoire,” she said, “anal sex is becoming the new ‘Will she do it or not?’ behavior, the new ‘Prove you love me.’” And still, she added, “girls’ sexual pleasure is not part of the equation.” According to Herbenick, the rise of anal sex places new pressures on young women to perform or else be labeled a prude. “It’s a metaphor, a symbol in one concrete behavior for the lack of education about sex, the normalization of female pain, and the way what had once been stigmatized has, over the course of a decade, become expected. If you don’t want to do it you’re suddenly not good enough, you’re frigid, you’re missing out, you’re not exploring your sexuality, you’re not adventurous. "
