A double standard is the application of different sets of principles for situations that are, in principle, the same, and is often used to describe freedom that is given to one party over another. A double-standard arises when two or more people, circumstances, or events are treated differently even though they should be treated the same way. Margaret Eichler, author of The Double Standard: A Feminist Critique of Feminist Social Science, explains that a double standard “implies that two things which are the same are measured by different standards”.

Margaret Eichler, author of The Double Standard: A Feminist Critique of Feminist Social Science, explains that a double standard “implies that two things which are the same are measured by different standards”. Applying different principles to similar-looking situations may or may not indicate a double standard. In order to distinguish between the application of a double-standard and the valid application of different standards towards circumstances that only appear to be the same, several factors must be examined. One is the sameness of those circumstances - what are the parallels between those circumstances, and in what ways do they differ?. Another is the philosophy or belief system informing which principles should be applied to those circumstances. Different standards can be applied to situations that appear similar based on a qualifying truth or fact that, upon closer examination, renders those situations distinct (i.e. a physical reality, a moral obligation etc.). However, if similar-looking situations have been treated according to different principles and there is no truth, fact or principle that distinguishes those situations, then a double standard has been applied. If correctly identified, a double standard is viewed negatively as it usually indicates the presence of hypocritical, biased and/or unfair attitudes leading to unjust behaviors. The role that gender plays in determining people's moral, social, political, and legal contexts has been long-debated and often controversial. Some believe that differences in the way men and women are perceived and treated is a function of social and environmental norms, thus indicating a double standard. One frequently discussed issue concerns the claim that a double standard exists in society's judgment of women's and men's sexual conduct. Research has found that casual sexual activity is regarded as more acceptable for men than for women. Other research contends that women are held to stricter standards of competency than men, as shown in studies involving the completion of perceptual tasks. According to some, double standards between men and women can potentially exist with regards to dating, cohabitation, virginity, marriage/remarriage, sexual abuse/assault/harassment, domestic violence, and singleness. A double standard may arise if two or more groups who have equal rights under the law are given different degrees or legal protection or representation. Such double standards are seen as unjustified because they violate a basic maxim of modern legal jurisprudence to which many countries claim to adhere - that all parties should stand equal before the law. A double standard can therefore be described as a biased or morally unfair application of that maxim. Where judges and leaders are expected to be impartial (such as in a court of law), they are expected to apply the same standards to all people regardless of their own subjective biases or favoritism based on social class, rank, ethnicity, gender, religion, sexual orientation, age, or other distinctions. A double standard arises in politics when the treatment of the same political matters between two or more parties (such as the response to a public crisis or the allocation of funding) is handled differently. This could occur because of the nature of political relationships between those tasked with these matters, the degree of reward or power that stands to be gained/lost, or the personal biases/prejudices of politicians. Double standard policies can include situations when the assessment of the same phenomenon, process or event in the international relations depends on character of the relations of the estimating parties with assessment objects. At identical filling of action of one country get support and a justification, and other – is condemned and punished. The following phrase became an example of policy of double standards: 'One man's terrorist is another man's freedom fighter', entered into use by the British writer Gerald Seymour in his work Harry's Game in 1975.
