Chapter 2 examines criteria that people use when forming perceptions of how they and others have been treated is fair or unfair. One of the important criteria that people use is whether they were given sufficient opportunities to voice their opinions about important issues at stake. It is crucial that voiced opinions are given due consideration. Being treated in a polite and respectful manner by people, and especially people of power, is also among the core criteria for evaluating procedural fairness. Generally being treated in a fair and just manner by competent and professional authorities is also among the important criteria of perceived procedural fairness. Taken together, perceived procedural fairness boils down to feeling to be a full-fledged member of your community and society and, ideally, the entire world.
