Friendship: The Laws of Attraction

My best friend, Olivia, and I met in a fiction-writing class many years ago. We bonded in an instant during the discussion of one poor soul's incomprehensible story involving a woman who'd undergone surgery and was described delicately as having lost "that which made her a woman." Suddenly, out of my mouth sprang my impersonation of Monty Python's Eric Idle, "Nudge, nudge, wink, wink, know what I mean?" Every other student in the room looked at me as if I'd lost my mind, but Olivia snorted with laughter. Thus, a friendship was born.

When people are asked, "What gives meaning to your life?" friendship figures at the top of the list. Yet the dynamics of friendship have remained mysterious and unquantifiable. Like romantic love, friendships were thought to "just happen." New research shows that the dance of friendship is nuanced—far more complex than commonly thought. With intriguing accuracy, sociologists and psychologists have delineated the forces that attract and bind friends to each other, beginning with the transition from acquaintanceship to friendship. They've traced the patterns of intimacy that emerge between friends and deduced the once ineffable "something" that elevates a friend to the vaunted status of "best." These interactions are minute but profound; they are the dark matter of friendship.

Entering The Friendship Zone

Years ago researchers conducted a study in which they followed the friendships in a single two-story apartment building. People tended to be friends with the neighbors on their respective floors, although those on the ground floor near the mailboxes and the stairway had friends on both floors. Friendship was least likely between someone on the first floor and someone on the second. As the study suggests, friends are often those who cross paths with regularity; our friends tend to be coworkers, classmates, and people we run into at the gym.

It's no surprise that bonds form between those who interact. Yet the process is more complex: Why do we wind up chatting with one person in our yoga class and not another? The answer might seem self-evident—our friend-in-the-making likes to garden, as do we, or shares our passion for NASCAR or Tex-Mex cooking. She laughs at our jokes, and we laugh at hers. In short, we have things in common.

But there's more: Self-disclosure characterizes the moment when a pair leaves the realm of buddyhood for the rarefied zone of true friendship. "Can I talk to you for a minute?" may well be the very words you say to someone who is about to become a friend.

"The transition from acquaintanceship to friendship is typically characterized by an increase in both the breadth and depth of self-disclosure," asserts University of Winnipeg sociologist Beverley Fehr, author of Friendship Processes. "In the early stages of friendship, this tends to be a gradual, reciprocal process. One person takes the risk of disclosing personal information and then 'tests' whether the other reciprocates."

Reciprocity is key. Years ago, fresh out of film school, I landed my first job, at a literary agency. I became what I thought was friends with another assistant, who worked, as I did, for an infamously bad-tempered agent. We ate lunch together almost every day. Our camaraderie was fierce, like that of soldiers during wartime. Then she found a new job working for a publicist down the street. We still met for lunch once a week. In lieu of complaining about our bosses, I told her about my concerns that I wasn't ready to move in with my boyfriend. She listened politely, but she never divulged anything personal about her own life. Eventually our lunches petered out to once a month, before she drifted out of my life for good. I was eager to tell her my problems, but she wasn't eager to tell me hers. The necessary reciprocity was missing, so our acquaintanceship never tipped over into friendship.

Why Some (And Only Some) Friends Stick

Once a friendship is established through self-disclosure and reciprocity, the glue that binds is intimacy. According to Fehr's research, people in successful same-sex friendships seem to possess a well-developed, intuitive understanding of the give and take of intimacy. "Those who know what to say in response to another person's self-disclosure are more likely to develop satisfying friendships," she says. Hefty helpings of emotional expressiveness and unconditional support are ingredients here, followed by acceptance, loyalty, and trust. Our friends are there for us through thick and thin, but rarely cross the line: A friend with too many opinions about our wardrobe, our partner, or our taste in movies and art may not be a friend for long.

When someone embodies the rules—instinctually—their friendships are abundant indeed. Kathy is one of my oldest friends; we were roommates in graduate school and have been through cross-country moves, divorces, deaths, and births together. Her ability to be a friend shines during a lousy breakup. She knows when to listen and make sympathetic sounds, when to act good and outraged at your ex's bad behavior, when to give you a hug, and when to tell you to stop obsessing and enjoy a glass of wine. She knows when to offer you her couch. It's this responsiveness that accounts for her having more friends than anyone I know—certainly more than the five our mothers told us we were lucky to be able to count on one hand over the course of a lifetime.
