There are many forms of discrimination, besides the more familiar forms like race and gender, based on ethnicity, religion, sexual orientation, age , disability or handicap, and sexual harassment. The mentioned characterization refers to a situation of the direct discrimination, in which a person is treated adversely directly on the basis of a prohibited ground. Indirect discrimination, refers to a situation in which an apparently neutral provision or practice is discriminatory in its effects. Besides direct and indirect discrimination, we may use the term institutional discrimination. Institutional discrimination refers to the practices or procedures in a company or an institution, or even the society as a whole, which are structured in a way that tends to produce discriminatory effects, for example in the Apartheid regime in South Africa.As to the root cause, discrimination appears to be no clear acceptance of any theory of causation but that discrimination often causes a chain reaction of disadvantages. For instance, it should be noted that there is a connection also between discrimination and social distance, given that it is usually psychologically easier to discriminate against people that one is not familiar with.
