One example of the influence of postmodernism on people's thought would be the rise of cultural relativism. Postmodernists tend to question whether there is a single set of assumptions or norms that all people should live by. So a person who views different cultural systems or beliefs as being more or less equal is embracing a view associated with postmodernism. Another postmodern perspective might be someone who questions what we are capable of knowing, even through such accepted disciplines as science or history. One example of this might be a historian who questions how we can construct narratives to explain events in the past.
