A fair distribution is one in which individuals who are similar in relevant respects receive similar benefits and costs (Pojman, 1989; Rachels, 1999; Velasquez, 1998).The challenge in applying this principle is in deciding on what base individuals are similar. That is, what characteristics are relevant in deciding whether people are similar and their for deserving of similar benefits and costs? There are at least five different perspectives people use in evaluating whether or not are distribution of good and harm is fair.
