" The transparency problem ends up in the same place as the default-to-truth problem. Our strategies for dealing with strangers are deeply flawed, but they are also socially necessary. We need the criminal-justice system and the hiring process and the selection of babysitters to be human. But the requirement of humanity means that we have to tolerate an enormous amount of error. That is the paradox of talking to strangers. We need to talk to them. But we’re terrible at it—and, as we’ll see in the next two chapters, we’re not always honest with one another about just how terrible at it we are. "
