There are a lot of ways to study a painting, and one of the best is to get to know the painter. The splash or splatter of color makes a lot more sense when you understand the rage or whimsy or heart behind it. The songwriter, similarly, can lay bare the song, the poet the poem, the builder the building.
So what explains the complex bit of artistry that is the human personality? We may not be born as tabulae rasae. Any parent can tell you that each child comes from the womb with an individual temperament that seems preloaded at the factory. But from the moment of birth, a lot of things set to work on that temperament--moderating it, challenging it, annealing it, wounding it. What we're left with after 10 or 20 or 50 years is quite different from what we started out with.
For a long time, researchers have tried to nail down just what shapes us--or what, at least, shapes us most. And over the years, they've had a lot of eureka moments. First it was our parents, particularly our mothers. Then it was our genes. Next it was our peers, who show up last but hold great sway. And all those ideas were good ones--but only as far as they went.
The fact is once investigators had strip-mined all the data from those theories, they still came away with as many questions as answers. Somewhere, there was a sort of temperamental dark matter exerting an invisible gravitational pull of its own. More and more, scientists are concluding that this unexplained force is our siblings.
From the time they are born, our brothers and sisters are our collaborators and co-conspirators, our role models and cautionary tales. They are our scolds, protectors, goads, tormentors, playmates, counselors, sources of envy, objects of pride. They teach us how to resolve conflicts and how not to; how to conduct friendships and when to walk away from them. Sisters teach brothers about the mysteries of girls; brothers teach sisters about the puzzle of boys. Our spouses arrive comparatively late in our lives; our parents eventually leave us. Our siblings may be the only people we'll ever know who truly qualify as partners for life. "Siblings," says family sociologist Katherine Conger of the University of California, Davis, "are with us for the whole journey."
Within the scientific community, siblings have not been wholly ignored, but research has been limited mostly to discussions of birth order. Older sibs were said to be strivers; younger ones rebels; middle kids the lost souls. The stereotypes were broad, if not entirely untrue, and there the discussion mostly ended.
But all that's changing. At research centers in the U.S., Canada, Europe and elsewhere, investigators are launching a wealth of new studies into the sibling dynamic, looking at ways brothers and sisters steer one another into--or away from--risky behavior; how they form a protective buffer against family upheaval; how they educate one another about the opposite sex; how all siblings compete for family recognition and come to terms--or blows--over such impossibly charged issues as parental favoritism.
From that research, scientists are gaining intriguing insights into the people we become as adults. Does the manager who runs a congenial office call on the peacemaking skills learned in the family playroom? Does the student struggling with a professor who plays favorites summon up the coping skills acquired from dealing with a sister who was Daddy's girl? Do husbands and wives benefit from the intergender negotiations they waged when their most important partners were their sisters and brothers? All that is under investigation. "Siblings have just been off the radar screen until now," says Conger. But today serious work is revealing exactly how our brothers and sisters influence us.
•Why childhood fights between siblings can be good
THE FIRST THING THAT STRIKES contemporary researchers when they study siblings is the sheer quantity of time the kids spend in one another's presence and the power this has to teach them social skills. By the time children are 11, they devote about 33% of their free time to their siblings--more time than they spend with friends, parents, teachers or even by themselves--according to a well-regarded Penn State University study published in 1996. Later research, published last year, found that even adolescents, who have usually begun going their own way, devote at least 10 hours a week to activities with their siblings--a lot when you consider that with school, sports, dates and sleep, there aren't a whole lot of free hours left. In Mexican-American homes, where broods are generally bigger, the figure tops 17 hours.
"In general," says psychologist Daniel Shaw of the University of Pittsburgh, "parents serve the same big-picture role as doctors on grand rounds. Siblings are like the nurses on the ward. They're there every day." All that proximity breeds an awful lot of intimacy--and an awful lot of friction.
Laurie Kramer, professor of applied family studies at the University of Illinois at Urbana-Champaign, has found that, on average, sibs between 3 and 7 years old engage in some kind of conflict 3.5 times an hour. Kids in the 2-to-4 age group top out at 6.3--or more than one clash every 10 minutes, according to a Canadian study. "Getting along with a sister or brother," Kramer says dryly, "can be a frustrating experience."
