" Whether it is the forming of a group of friends or a pod at work—or hiring for diversity of viewpoint and tolerance for dissent when you are able to guide an enterprise’s culture toward accuracy—we should guard against gravitating toward clones of ourselves. We should also recognize that it’s really hard: the norm is toward homogeneity; we’re all guilty of it; and we don’t even notice that we’re doing it. "
