A double standard is the application of different sets of principles for similar situations. A double standard may take the form of an instance in which certain concepts (often, for example, a word, phrase, social norm, or rule) are perceived as acceptable to be applied by one group of people, but are considered unacceptable—taboo—when applied by another group.
The concept of a double standard has long been applied (as early as 1872) to the fact that different moral structures are often applied to men and women in society.
A double standard can therefore be described as a biased or morally unfair application of the principle that all are equal in their freedoms. Such double standards are seen as unjustified because they violate a basic maxim of modern legal jurisprudence: that all parties should stand equal before the law. Double standards also violate the principle of justice known as impartiality, which is based on the assumption that the same standards should be applied to all people, without regard to subjective bias or favoritism based on social class, rank, ethnicity, gender, religion, sexual orientation, age or other distinctions. A double standard violates this principle by holding different people accountable according to different standards.
Double standards refers to having different standards for two different people. For example If Joe believes that it's ok for guys to "sleep around" but he also believes that it's NOT ok for gals to "sleep around" ... THAT'S a double standard
A double standard is when someone feels it's okay for them to do something, but it's not okay for you to do it (say if this guy felt it was okay for him to flirt with others, but he didn't like it if you flirted with others).
