But the three components are distinguishable and can exist independently, as follows. Race prejudice is the usual term for the affective component of racism. A person may have a mild or strong aversion to people of another race for no very obvious good reason. For example, Japanese people do not like the way Caucasians smell. But it will tend to lead to selective exposure to people of other races and even to pre-judging information about them.
Race realism is the most obvious term for the cognitive component of racism.
Here the person entertains sincere beliefs about race differences which are taken to be reasonably important and quite deep-seated. Scientists who are race realists believe that good evidence and cogent arguments can be found to support race realism. Since the Jensen heresy of 1969, it has been standard practice of anti-racists to try to pretend that all such scientific thinking is essentially Nazi in tendency or inspiration despite the fact that Hitler banned IQ testing and brought about the greatest destruction of intellectual talent in his country since the French had driven their Protestand middle class to Berlin by the Massacre of St Bartholomew s Day. Racial discrimination is the conative component of racism. The proponent seeks to discriminate according to race as a matter of public policy.
