Double Standards

A double standard is the application of different sets of principles for situations that are, in principle, the same. It is often used to describe treatment whereby one group is given more latitude than another. A double standard arises when two or more people, groups, organizations, circumstances, or events are treated differently even though they should be treated the same way. A double standard "implies that two things which are the same are measured by different standards".
