If we are honest with ourselves, we have long known that masculinity kills men, in ways both myriad and measurable. While social constructions of femininity demand that women be thin, beautiful, accommodating, and some unattainable balance of virginal and fuckable, social constructions of masculinity demand that men constantly prove and re-prove the very fact that they are, well, men.

Both ideas are poisonous and potentially destructive, but statistically speaking, the number of addicted and afflicted men and their comparatively shorter lifespans proves masculinity is actually the more effective killer, getting the job done faster and in greater numbers. Masculinity’s death tolls are attributed to its more specific manifestations: alcoholism, workaholism and violence. Even when it does not literally kill, it causes a sort of spiritual death, leaving many men traumatized, dissociated and often unknowingly depressed. (These issues are heightened by race, class, sexuality and other marginalizing factors, but here let’s focus on early childhood and adolescent socialization overall.) To quote poet Elizabeth Barrett Browning, “tis not in death that men die most.” And for many men, the process begins long before manhood.

The emotionally damaging “masculinization” of boys starts even before boyhood, in infancy. Psychologist Terry Real, in his 1998 book I Don’t Want to Talk About It: Overcoming the Secret Legacy of Male Depression, highlights numerous studies which find that parents often unconsciously begin projecting a kind of innate “manliness”—and thus, a diminished need for comfort, protection and affection—onto baby boys as young as newborns. This, despite the fact that gendered behaviors are absent in babies; male infants actually behave in ways our society defines as “feminine.” As Real explains, “[l]ittle boys and little girls start off… equally emotional, expressive, and dependent, equally desirous of physical affection. At the youngest ages, both boys and girls are more like a stereotypical girl. If any differences exist, little boys are, in fact, slightly more sensitive and expressive than little girls. They cry more easily, seem more easily frustrated, appear more upset when a caregiver leaves the room.”

Yet both mothers and fathers imagine inherent sex-related differences between baby girls and boys. Even when researchers controlled for babies’ “weight, length, alertness, and strength,” parents overwhelmingly reported that baby girls were more delicate and “softer” than baby boys; they imagined baby boys to be bigger and generally “stronger.” When a group of 204 adults was shown video of the same baby crying and given differing information about the baby’s sex, they judged the “female” baby to be scared, while the “male” baby was described as “angry.”

Intuitively, these differences in perception create correlating differences in the kind of parental caregiving newborn boys receive. In the words of the researchers themselves, “it would seem reasonable to assume that a child who is thought to be afraid is held and cuddled more than a child who is thought to be angry.” That theory is bolstered by other studies Real cites, which consistently find that “from the moment of birth, boys are spoken to less than girls, comforted less, nurtured less.” To put it bluntly, we begin emotionally shortchanging boys right out of the gate, at the most vulnerable point in their lives.
