Blink: The Power of Thinking Without Thinking

by Malcolm Gladwell

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.
