<P> Though gender discrimination and sexism refer to beliefs and attitudes in relation to the gender of a person, such beliefs and attitudes are of a social nature and do not, normally, carry any legal consequences . Sex discrimination, on the other hand, may have legal consequences . Though what constitutes sex discrimination varies between countries, the essence is that it is an adverse action taken by one person against another person that would not have occurred had the person been of another sex . Discrimination of that nature is considered a form of prejudice and in certain enumerated circumstances is illegal in many countries . </P> <P> Sexual discrimination can arise in different contexts . For instance, an employee may be discriminated against by being asked discriminatory questions during a job interview, or by an employer not hiring or promoting, unequally paying, or wrongfully terminating, an employee based on their gender . </P> <P> Sexual discrimination can also arise when the dominant group holds a bias against the minority group . One such example is Wikipedia . In the Wikipedian community, around 13 percent of registered users are women . This creates gender imbalances, and leaves room for systemic bias . Women are not only more harshly scrutinized, but the representation of women authors are also overlooked . Relative to men, across all source lists, women have a 2.6 greater odds of omission in Wikipedia . In an educational setting, there could be claims that a student was excluded from an educational institution, program, opportunity, loan, student group, or scholarship because of their gender . In the housing setting, there could be claims that a person was refused negotiations on seeking a house, contracting / leasing a house or getting a loan based on their gender . Another setting where there have been claims of gender discrimination is banking; for example if one is refused credit or is offered unequal loan terms based on one's gender . As with other forms of unlawful discrimination, there are two types of sex discrimination--direct discrimination and indirect discrimination . Direct sex discrimination is fairly easy to spot --' Barmaid wanted', but indirect sex discrimination, where an unnecessary requirement puts one sex at a disproportionate disadvantage compared to the opposite sex, is sometimes less easy to spot, although some are obvious --' Bar person wanted--must look good in a mini skirt' . Another setting where there is usually gender discrimination is when one is refused to extend their credit, refused approval of credit / loan process, and if there is a burden of unequal loan terms based on one's gender . Socially, sexual differences have been used to justify different roles for men and women, in some cases giving rise to claims of primary and secondary roles . While there are alleged non-physical differences between men and women, major reviews of the academic literature on gender difference find only a tiny minority of characteristics where there are consistent psychological differences between men and women, and these relate directly to experiences grounded in biological difference . However, there are also some psychological differences in regard to how problems are dealt with and emotional perceptions and reactions that may relate to hormones and the successful characteristics of each gender during longstanding roles in past primitive lifestyles . </P> <P> Unfair discrimination usually follows the gender stereotyping held by a society . </P>
