Blink_ The Power of Thinking Without Thinking - Malcolm Gladwell [10]
“It’s so easy to tell,” Gottman says. “I just looked at this tape yesterday. The woman says, ‘We met at a ski weekend, and he was there with a bunch of his friends, and I kind of liked him and we made a date to be together. But then he drank too much, and he went home and went to sleep, and I was waiting for him for three hours. I woke him up, and I said I don’t appreciate being treated this way. You’re really not a nice person. And he said, yeah, hey, I really had a lot to drink.’ ” There was a troubling pattern in their first interaction, and the sad truth was that that pattern persisted throughout their relationship. “It’s not that hard,” Gottman went on. “When I first started doing these interviews, I thought maybe we were getting these people on a crappy day. But the prediction levels are just so high, and if you do it again, you get the same pattern over and over again.”
One way to understand what Gottman is saying about marriages is to use the analogy of what people in the world of Morse code call a fist. Morse code is made up of dots and dashes, each of which has its own prescribed length. But no one ever replicates those prescribed lengths perfectly. When operators send a message — particularly using the old manual machines known as the straight key or the bug — they vary the spacing or stretch out the dots and dashes or combine dots and dashes and spaces in a particular rhythm. Morse code is like speech. Everyone has a different voice.
In the Second World War, the British assembled thousands of so-called interceptors — mostly women — whose job it was to tune in every day and night to the radio broadcasts of the various divisions of the German military. The Germans were, of course, broadcasting in code, so — at least in the early part of the war — the British couldn’t understand what was being said. But that didn’t necessarily matter, because before long, just by listening to the cadence of the transmission, the interceptors began to pick up on the individual fists of the German operators, and by doing so, they knew something nearly as important, which was who was doing the sending. “If you listened to the same call signs over a certain period, you would begin to recognize that there were, say, three or four different operators in that unit, working on a shift system, each with his own characteristics,” says Nigel West, a British military historian. “And invariably, quite apart from the text, there would be the preambles, and the illicit exchanges. How are you today? How’s the girlfriend? What’s the weather like in Munich? So you fill out a little card, on which you write down all that kind of information, and pretty soon you have a kind of relationship with that person.”
The interceptors came up with descriptions of the fists and styles of the operators they were following. They assigned them names and assembled elaborate profiles of their personalities. After they identified the person who was sending the message, the interceptors would then locate their signal. So now they knew something more. They knew who was where. West goes on: “The interceptors had such a good handle on the transmitting characteristics of the German radio operators that they could literally follow them around Europe — wherever they were. That was extraordinarily valuable in constructing an order of battle, which is a diagram of what the individual military units in the field are doing and what their location is. If a particular radio operator was with a particular unit and transmitting from Florence, and then three weeks later you recognized that same operator, only this time he was in Linz, then you could assume that that particular unit had moved from northern Italy to the eastern front. Or you would know that a particular operator was with a tank repair unit and he always came up on the air every day at twelve o’clock. But now, after a big battle, he’s coming up at twelve, four in the afternoon, and seven in the evening, so you can
