rule that applies to one group but not another
Double standard It is most commonly seen as a decisive psychological tool used to defend one’s ego or subconscious from the shortcomings of one’s own set of values or contrasting principles.[2] It is the employment of a hypocritical and biased standpoint, with which to separate the seemingly bad in others from the bad in oneself by having two sets of rules for the same concept. Margaret Eichler, author of The Double Standard, explains that a double standard “implies that two things which are the same are measured by different standards” (Eichler 1980:15).
