Male/Female Differences (updated)

These Physiological and Chemical Differences are Real!

(NYTs) In a female mouse’s brain, a left-to-right pattern in the silencing of the X chromosome. These patterns may influence how individual brains function…. In some brains, for example, a mother’s X chromosome was seen dominating the left side, while the father’s dominated the right. Entire organs can be skewed toward one parent. Dr. Nathans and his colleagues found that in some mice, one eye was dominated by the father and the other by the mother. The diversity even extended to the entire mouse. In some animals, almost all the X chromosomes from one parent were shut; in others, the opposite was true…. Dr. Nathans speculates that using chromosomes from both parents is especially useful in the nervous system. It could create more ways to process information. “Diversity in the brain is the name of the game,” he said. ~ h/t Uncommon Design

Are there physiological differences between the sexes that would naturally (or by design) cause one sex to excel in one aspect and not in another? In this short presentation, one lie of 12, you will see an exposing of how politically-correct feminists have undermined what otherwise is common sense.

Neural Wiring

The participants were split into three age groups, aged eight to 13, 13 and four months to 16, and 17 to 22. The youngest group’s brains showed far less difference than those of the older two.


In one of the largest studies looking at the “connectomes” of the sexes, Ragini Verma, PhD, an associate professor in the department of Radiology at the Perelman School of Medicine at the University of Pennsylvania, and colleagues found greater neural connectivity from front to back and within one hemisphere in males, suggesting their brains are structured to facilitate connectivity between perception and coordinated action. In contrast, in females, the wiring goes between the left and right hemispheres, suggesting that they facilitate communication between the analytical and intuition.

“These maps show us a stark difference–and complementarity–in the architecture of the human brain that helps provide a potential neural basis as to why men excel at certain tasks, and women at others,” said Verma.

For instance, on average, men are more likely better at learning and performing a single task at hand, like cycling or navigating directions, whereas women have superior memory and social cognition skills, making them more equipped for multitasking and creating solutions that work for a group. They have a mentalistic approach, so to speak.

Past studies have shown sex differences in the brain, but the neural wiring connecting regions across the whole brain that have been tied to such cognitive skills has never been fully shown in a large population.

Dennis Prager point out that “many in the university are not even intellectually open in the natural sciences if an idea may clash with Left-wing opinion.” He continues,

In a talk before fellow economists, the same Lawrence Summers, when he was president of Harvard University (he had been secretary of the Treasury under President Bill Clinton), addressed the issue of why there were so many fewer women than men in some areas of science, in math, and in engineering. He suggested that among other reasons, one might be that women’s brains are less suited to these subjects than men’s brains. More than one hundred Harvard professors signed a petition against President Summers, Left-wing alumni threatened not to give any more money to Harvard, and the vast majority of Harvard’s professors kept a cowardly silence while their colleagues sought to suppress completely respectable intellectual inquiry. Consequently, President Summers felt forced to apologize. In the year 2005, nearly four centuries after Galileo was forced by the then-dominant Catholic Church to recant observable scientific facts about our solar system, the president of Harvard University, an institution whose motto is Veritas (“Truth”), was forced by the now-dominant Left to recant observable facts about men and women.

The Atlantic Monthly adds their thoughts on the matter:

Like religious fundamentalists seeking to stamp out the teaching of evolution, feminists stomped Harvard University President Lawrence Summers for mentioning at a January 14 academic conference the entirely reasonable theory that innate male-female differences might possibly help explain why so many mathematics, engineering, and hard-science faculties remain so heavily male.

Unlike most religious fundamentalists, these feminists were pursuing a careerist, self-serving agenda. This cause can put money in their pockets.

Summers’s suggestion—now ignominiously retracted, with groveling, Soviet-show-trial-style apologies—was that sex discrimination and the reluctance of mothers to work 80 hours a week are not the only possible explanations for gender imbalances in the math-science area. He noted that high school boys have many more of the highest math scores than girls, and suggested that this might reflect genetic differences. He also stressed the need for further research into all three possible explanations.

The foul brute may as well have rapped that women are “hos,” or declared that they should be kept barefoot and pregnant. The most remarkable feminist exercise in self-parody was that of MIT biology professor Nancy Hopkins, who famously told reporters that she “felt I was going to be sick,” that “my heart was pounding and my breath was shallow,” that “I just couldn’t breathe, because this kind of bias makes me physically ill,” and that she had to flee the room because otherwise “I would’ve either blacked out or thrown up.”

Such fatuous feminist fulminations have been good fun, as have the eviscerations of Hopkins as a latter-day “Victorian maiden exposed to male coarseness, [who] suffers the vapors and collapses on the drawing room carpet in a heap of crinolines,” in the words of George Will. (More on Hopkins below.) But most of the commentary has glossed over one important point:

For all its foolishness and irrationality, the feminist hysteria about Summers furthers the career agendas of feminists who seek thinly veiled job preferences or quotas for themselves and their friends. Such preferences are most easily justified as a remedy for male bias. And bias can more easily be blamed for gender imbalances if the possibility that more men than women are gifted with math-science brilliance is banished from public discourse.

This feminist-careerist agenda is conveniently ignored by the less hysterical critics of Summers, who make no claim that he said anything inaccurate but nonetheless reproach him for what a Los Angeles Times editorial portrayed as a gratuitous and insensitive ego trip. To the contrary, until his disgraceful capitulation to the power of political correctness, Summers was making a much-needed effort to break the self-serving feminist-careerist stranglehold on honest discussion of gender imbalances….

WebMD comments on the science involved:

Recent studies highlight a long-held suspicion about the brains of males and females. They’re not the same. So how does the brain of a female look and function differently from a male’s brain, and what accounts for these differences?

Disparities Start Early in Life

Scientists now know that sex hormones begin to exert their influence during development of the fetus. A recent study by Israeli researchers that examined male and female brains found distinct differences in the developing fetus at just 26 weeks of pregnancy. The disparities could be seen when using an ultrasound scanner. The corpus callosum — the bridge of nerve tissue that connects the right and left sides of the brain — had a thicker measurement in female fetuses than in male fetuses.

Observations of adult brains show that this area may remain stronger in females. “Females seem to have language functioning in both sides of the brain,” says Martha Bridge Denckla, PhD, a research scientist at Kennedy Krieger Institute.

Consider these recent findings. Researchers, using brain imaging technology that captures blood flow to “working” parts of the brain, analyzed how men and women process language. All subjects listened to a novel. When males listened, only the left hemisphere of their brains was activated. The brains of female subjects, however, showed activity on both the left and right hemispheres.

This activity across both hemispheres of the brain may result in the strong language skills typically displayed by females. “If there’s more area dedicated to a set of skills, it follows that the skills will be more refined,” says David Geary, PhD, professor of psychological sciences at the University of Missouri.

As a whole, girls outperform boys in the use of language and fine motor skills until puberty, notes Denckla. Boys also fall prey to learning disabilities more frequently than girls. “Clinics see a preponderance of boys with dyslexia,” Denckla tells WebMD. ADHD also strikes more boys than girls. The symptoms displayed by girls and boys with ADHD differ, too. Girls with ADHD usually exhibit inattention, while affected boys are prone to lack of impulse control. But not all differences favor girls.

Boys generally demonstrate superiority over female peers in areas of the brain involved in math and geometry. These areas of the brain mature about four years earlier in boys than in girls, according to a recent study that measured brain development in more than 500 children. Researchers concluded that when it comes to math, the brain of a 12-year-old girl resembles that of an 8-year-old boy. Conversely, the same researchers found that areas of the brain involved in language and fine motor skills (such as handwriting) mature about six years earlier in girls than in boys…

Geary suggests that women use language skills to their advantage. “Females use language more when they compete. They gossip, manipulate information,” he says. Geary suggests that this behavior, referred to as relational aggression, may have given females a survival advantage long ago. “If the ability to use language to organize relationships was of benefit during evolutionary history, and used more frequently by women, we would expect language differences to become exaggerated,” he tells WebMD. Women also use language to build relationships, theorizes Geary. “Women pause more, allow the other friend to speak more, offer facilitative gestures,” he says.

When it comes to performing activities that require spatial skills, like navigating directions, men generally do better. “Women use the cerebral cortex for solving problems that require navigational skills. Men use an entirely different area, mainly the left hippocampus — a nucleus deep inside the brain that’s not activated in the women’s brains during navigational tasks,” Geary tells WebMD. The hippocampus, he explains, automatically codes where you are in space. As a result, Geary says: “Women are more likely to rely on landmark cues: they might suggest you turn at the 7-11 and make a right at the church, whereas men are more likely to navigate via depth reckoning — go east, then west, etc.”….

Another brain website comments:

…The female and male brain is different and the two brains process information differently. The good news is that with some conscious effort communication can be enhanced between the brains and frustrations lowered.

In general, female brains tend to employ both sides of their brain to process information while male brains tend to rely primarily on their dominant or language side to process. As the dominant hemisphere tends to be analytic, problem solving, task oriented, detailed, and verbal this helps to explain male behavior. A female brain can also process in this manner, but the non-dominant hemisphere that can process emotion, meaning without words, empathy, tone, and disposition is also engaged by the female.

Perhaps this helps to explain why females enjoy shopping while most men view it as a chore, women vote differently than males, men and women struggle communicating with each other, and men do not understand psychotherapy. Men tend to be more isolative, less talkative, and focused on solution. Women tend to be more group oriented, more talkative, and focused on the means and not necessarily the ends. This gets played out in the U.S. at this time as women and men tend to view the same debate between candidates differently (men tend to focus on content and women both content and style)…
