I came across this info while reading thru Malcom Gladwells book titled "Blink - The Power
of Thinking Without Thinking". This particular passage was comparing the observation of
interactions between husbands and wives to, of all things, distinct fists of radio ops in WW2.
Interesting reading... I don't necessarily agree with the findings, but I was impressed with the
morse code op reference.

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 bugthey 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 interceptorsmostly 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, soat least in the early part of the warthe
British couldnt understand was being said. But that didnt 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 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? Hows the girlfriend? Whats 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 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 Europewherever
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 oclock. But now, after a big battle, hes coming up at twelve, four in the
afternoon, and seven in the evening, so you can assume that unit has a lot of work going on. And in a moment
of crisis, when someone very high up asks, Can you really be absolutely certain that this particular Luftwaffe
[German air force squadron] is outside of Tobruk and not in Italy? you can answer, Yes, that was
Oscar, we are absolutely sure.
The key thing about fists is that they emerge naturally. Radio operators dont deliberately try to sound
distinctive. They simply end up sounding distinctive, because some part of their personality appears to express
itself automatically and unconsciously in the way they work the Morse code keys. The other thing about a fist is
that it reveals itself in even the smallest sample of Morse code. We have to listen to only a few characters to
pick out an individuals pattern. It doesnt change or disappear for stretches or show up only in certain words or
phrases. Thats why the British interceptors could listen to just a few bursts and say, with absolute certainty,
Its Oscar, which means that yes, his unit is now definitely outside of Tobruk. An operators fist is stable.
What Gottman is saying is that a relationship between two people has a fist as well: a distinctive signature
that arises naturally and automatically. That is why a marriage can be read and decoded so easily, because some
key part of human activitywhether it is something as simple as pounding out a Morse code message or as
complex as being married to someonehas an identifiable and stable pattern. Predicting divorce, like tracking
Morse Code operators, is pattern recognition.
