We fall out of truth-default mode only when the case against our initial assumption becomes definitive. We do not behave, in other words, like sober-… - Malcolm Gladwell

We start by believing. And we stop believing only when our doubts and misgivings rise to the point where we can no longer explain them away.

The power of knowing, in that first two seconds, is not a gift given magically to a fortunate few. It is an ability that we can all cultivate for ourselves.

Somewhere in retirement, Haywood Hansell saw that announcement in the newspaper, and I’m sure he wondered why he didn’t get an award as well for the effort he put toward fighting a war with as few civilian casualties as possible. But we don’t give prizes to people who fail at their given tasks, no matter how noble their intentions, do we? To the victor go the spoils.

In Boston right around the same time, another criminologist did a similar study: Half the crime in the city came from 3.6 percent of the city’s blocks. That made two examples. Weisburd decided to look wherever he could: New York. Seattle. Cincinnati. Sherman looked in Kansas City, Dallas. Anytime someone asked, the two of them would run the numbers. And every place they looked, they saw the same thing: Crime in every city was concentrated in a tiny number of street segments. Weisburd decided to try a foreign city, somewhere entirely different — culturally, geographically, economically. His family was Israeli, so he thought Tel Aviv. Same thing. “I said, ‘Oh my God. Look at that! Why should it be that five percent of the streets in Tel Aviv produce fifty percent of the crime? There’s this thing going on, in places that are so different.’” Weisburd refers to this as the Law of Crime Concentration.6 Like suicide, crime is tied to very specific places and contexts. Weisburd’s experiences in the 72nd Precinct and in Minneapolis are not idiosyncratic. They capture something close to a fundamental truth about human behavior. And that means that when you confront the stranger, you have to ask yourself where and when you’re confronting the stranger — because those two things powerfully influence your interpretation of who the stranger is.
