The Psychology of We

powers of two

Two categories of people that can be hard to have a conversation with are good friends and people who have worked together for a long time. Sometimes it's like they are speaking their own language — and they are. But these connections can transcend conversation and touch on life.

In Powers of Two: Finding the Essence of Innovation in Creative Pairs, Joshua Shenk explores how the identity of pairs resemble that of a mosaic, “a series of pieces that connect to one another.”

A good place to begin is with ritual, since this is often the foundation of creative practice. Igor Stravinsky came into his studio and, first thing, sat down and played a Bach fugue. When he was writing The End of the Affair, Graham Greene produced five hundred words every day, and only five hundred, even if it meant stopping in the middle of a scene. The choreographer Twyla Tharp rises every morning at 5:30, puts on her workout clothes, and catches a taxi to the Pumping Iron gym at Ninety-First Street and First Avenue in Manhattan. “The ritual,” she writes in The Creative Habit, “is not the stretching and weight training I put my body through each morning at the gym; the ritual is the cab. The moment I tell the driver where to go I have completed the ritual.”

Tharp's point is that ritual emerges from the smallest, most concrete action. For pairs, the most basic thing is a regular meeting time. James Watson and Francis Crick had lunch most days at the Eagle pub in Cambridge. Facebook CEO Mark Zuckerberg and COO Sheryl Sandberg begin and end every week with hourlong private meetings. After they began to exchange their work, J.R.R. Tolkien and C. S. Lewis set aside Mondays to meet at a pub and later met with a group, the Inklings, every Thursday night at Lewis's apartment.

Meeting rituals may be tied to moments in time — as when partners like Buffett and Munger begin every day with a call—or to a physical space, as when Lennon and McCartney met at Paul's house to write. Watson and Crick ended up sharing an office at the Cavendish Laboratory in Cambridge because the other scientists in the lab couldn't stand their incessant chatter.

Moving towards each other as people often means leaving the rest of the world behind. “Every real friendship is a sort of secession, even a rebellion,” C. S. Lewis writes in The Four Loves.

In the midst of the feverish and entwined six-year collaboration between Braque and Picasso that led to cubism, both artists signed the back of each of their canvases; only they would know who did what. “People always ask Ulay and me the same questions,” Marina Abramovic told me. ‘”Whose idea was it?' or ‘How was this done?'… But we never specify. Everything was interrelated and interdependent.”

Partnerships often form impediments to others trying to look in. Outsiders are not part of the club, they are not doing the work, they don't have the shared understanding, the common goals, the …

This is one reason many epic partnerships end up as historical footnotes or become entirely effaced: “Things were said with Picasso during those years,” Braque said, “that no one will ever say again, things that no one could ever say any more, that no one could ever understand… things that would be incomprehensible and which gave us such joy.” This was one of the very few lines either man ever spoke about the relationship that helped give birth to modern art.

In addition to the physical gestures that a pair can share, there is also an unmistakable private language. This is the key to high-bandwidth communication.

Many pairs have what we could fairly call a private language. Tom Hanks described the communication between director Ron Howard and producer Brian Grazer as “some gestalt Vulcan.” Akio Morita and Ma- saru Ibuka, the cofounders of Sony, “would sit there talking to each other,” Morita's son Hideo said, “and we would listen but we had no idea what they were saying … It was gibberish to us, but they were understanding each other, and interrupting them for any reason was forbidden.”

Private language emerges organically from constant exchange. Intimate pairs talk fluidly and naturally, having let go of what psychologists call “self-monitoring”—the process of watching impulses and protean thoughts, censoring some, allowing others to pass one's lips. … The psychologist Daniel Kahneman makes the same point. “Like most people, I am somewhat cautious about exposing tentative thoughts to others,” he said. But after a while with Amos Tversky, “this caution was completely absent.”

You just get so high-bandwidth,” Bill Gates said about talking to Steve Ballmer, his longtime deputy at Microsoft (and eventual successor). “Steve and I would just be going from talking to meeting to talking to meeting, and then I'd stay up late at night, and write him five e-mails. He'd get up early in the morning and maybe not necessarily respond to them, but start thinking about them. And the minute I see him, he's [at the office whiteboard] saying we could move this guy over here and do this thing here.” Facebook's CEO Mark Zuckerberg used that same term, high- bandwidth, to describe his exchanges with his COO Sheryl Sandberg. “We can talk for 30 seconds and have more meaning be exchanged than in a lot of meetings that I have for an hour,” he said.

More than shared language, people develop into shared rhythms and syntactical structures of speech.

This is due in part to the astonishing power of mimicry, which psychologists call “social contagion.” Just by being near each other, the psychologist Elaine Hatfield has shown, people come to match accents, speech rates, vocal intensity, vocal frequency, pauses, and quickness to respond.

Psychologists used to think that people imitated each other in a deliberate attempt to be liked, but mimicry is far more pervasive than this — and largely nonconscious. Intimate partners share physical postures and breathing patterns too. They use the same muscles so often, the psychologist Robert Zajonc and colleagues found in a study of spouses, that they even come to look alike. Warren Buffett has said that he and Charlie Munger are “Siamese twins, practically.” In addition to wearing the same gray suits, the same Clark Kent glasses, and the same comb-overs, writes Buffett biographer Alice Schroeder, they also share a “lurching, awkward gait” and a flickering intensity in their eyes. Whether or not this is due to what Zajonc calls “repeated empathic mimicry,” we can't be sure, but one does wonder.

The larger point about any physical convergence is that it reflects what psychologists call a “shared coordinative structure.” Shared mannerisms, like similar walking gaits, often come along with shared emotions and ideas. Just as physical qualities are “highly communicable,” write psychologists Molly Ireland and James Pennebaker, so are behaviors, affective states, and beliefs.

Language is an unusually potent mechanism for psychic convergence, because it is so closely tied to thinking. “Linguistic coordination,” Ireland and Pennebaker explain, leads to “the cultivation of common ground (i.e., matching cognitive frameworks in which conversants adopt shared assumptions, linguistic referents, and knowledge).”

Of course eventually this goes telepathic.

Barry Sonnenfeld, who has directed photography on several films for the Coen brothers, remembers Ethan saying, after a take, “Hey, Joel, you know what?” And Joel replying: “Yeah, I know, I'm going to tell him.” When the writer David Zax visited The Daily Show to profile Steve Bodow, Jon Stewart's head writer at the time, Zax could understand only a small fraction of their exchanges, given the dominance of “workplace argot and quasi-telepathy.” “If you work with Jon for any length of time, you learn to interpret the short hand,” Bodow said. For example, Stewart might say: “Cut the thing and bring the thing around and do the thing.” ‘”Cut the thing': You know what thing needs to be cut,” Bodow explained. “‘Bring the thing around': There's a thing that works, but it needs to move up in order to set up the ‘do the thing' thing, which is probably the ‘blow,' the big joke at the end. It takes time and repetition and patience and frustration, and suddenly you know how to bring the thing around and do the thing.”
