To Parents The urge to create is equally strong in all children. Boys and girls. It’s the imagination that counts. Not skill. You build whatever comes into your head, the way you want it. A bed or a truck. A dolls house or a spaceship. A lot of boys like dolls houses. They’re more human than spaceships. A lot of girls…
Margaret Troyer, a former Baltimore-area teacher, published the first paper showing that "yo" is being used to replace "he" and "she." Troyer first noticed it while she was teaching middle-school kids in the area. "Some examples would be 'yo wearing a jacket,' " Troyer says, referring to her research. "Another example…
he gender binary is the artificial division of the world into things that are "masculine" or "for men" and things that are "feminine" or "for women". One of the starkest ways to think of this is to consider the phrase "opposite sexes/genders" (as opposed to "different sexes/genders"), when both men and women are human…
A vivid demonstration of this difference can be seen by looking up the record number of children sired by a human female versus a male. If you were to guess the maximum number of children that a woman could produce in a lifetime, you’d probably say around fifteen. Guess again. The Guinness Book of World Records gives…
Different cultures today have evolved different sets of sexual mores, resulting in differences in male and female behavior. In Sweden, a social democracy where women have great economic independence, we see a high degree of sexual freedom among women. Without needing to depend on men for their security, Swedish women…
Why does the waist-to-hip ratio matter? Singh observes that a "gynoid" fat distribution—more fat on the hips, less on the torso—is necessary for the hormonal changes associated with female fertility. An "android" fat distribution-—fat on the belly, thin hips—is associated with the symptoms of male disabilities such as…
Hard porn, which depicts actual acts of sex, is almost invariably about the gratification of male lust by willing, easily aroused, varied, multiple, and physically attractive women (or men, in the case of gay porn). It is virtually devoid of context, plot, flirtation, courtship, and even much foreplay. There are no…
At school, boys are fidgety, difficult, inattentive, and slow to learn, compared to girls. Nineteen out of every twenty hyperactive children are boys. Four times as many boys as girls are dyslexic and learning disabled. "Education is almost a conspiracy against the aptitudes and inclinations of a schoolboy," wrote…
We last met the steroid hormone testosterone in fish and birds where it was rendering them more vulnerable to parasites by exaggerating their sexual ornaments. In recent years more and more evidence has been found that testosterone affects not just ornaments and bodies but also brains. Testosterone is an ancient…
There are three reasons to expect evolution to have produced different mentalities in men and women. The first is that men and women are mammals, and all mammals show sexual differences in behavior. As Charles Darwin put it, "No one disputes that the bull differs in disposition from the cow, the wild boar from the…
There are many well-established natural factors that bias the sex ratio of human offspring, proving that it is at least possible. The most famous is the returning-soldier effect. During and immediately after major wars, more sons are born than usual in the belligerent countries as if to replace the men that died…
Trivers and Willard realized that the same general principle of sex allocation, which determines the gender of nematodes and fish, applies even to those creatures that cannot change sex but that take care of their young. They predicted that animals would be found to have some systematic control over the sex ratio of…
