Two people may arrive at a conversation with very different conversational patterns. But almost instantly they reach a common ground. - Malcolm Gladwell

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.

Next time you meet a doctor, and you sit down in his office and he starts to talk, if you have the sense that he isn’t listening to you, that he’s talking down to you, and that he isn’t treating you with respect, listen to that feeling. You have thin-sliced him and found him wanting.

If you are going to do something truly innovative, you have to be someone who does not value social approval. You can’t need social approval to go forward.
