"The most intriguing candidate for that "something else" is called the Broken Windows theory. Broken Windows was the brainchild of the criminologist … - Malcolm Gladwell

This is called the “principle of legitimacy,” and legitimacy is based on three things. First of all, the people who are asked to obey authority have to feel like they have a voice — that if they speak up, they will be heard. Second, the law has to be predictable. There has to be a reasonable expectation that the rules tomorrow are going to be roughly the same as the rules today. And third, the authority has to be fair. It can’t treat one group differently from another.

If we want to, say, develop schools in disadvantaged communities that can successfully counteract the poisonous atmosphere of their surrounding neighborhoods, this tells us that we’re probably better off building lots of little schools than one or two big ones.

Whatever it is we are trying to find out about the strangers in our midst is not robust. The “truth” about Amanda Knox or Jerry Sandusky or KSM is not some hard and shiny object that can be extracted if only we dig deep enough and look hard enough. The thing we want to learn about a stranger is fragile. If we tread carelessly, it will crumple under our feet. And from that follows a second cautionary note: we need to accept that the search to understand a stranger has real limits. We will never know the whole truth. We have to be satisfied with something short of that. The right way to talk to strangers is with caution and humility. How many of the crises and controversies I have described would have been prevented had we taken those lessons to heart?
