Prejudices are the biased feelings and attitudes people of one class have about members of other classes. This is an opinion formed about a familiar thing without taking into consideration any evidence against it. Some prejudices are developed on mere hearsay. A prejudiced person refuses to examine any evidence. Even if he gets evidences to the contrary, he refuses to give up his previous opinion.
Prejudice can be positive or negative. Usually, it is used in a negative sense. But sometimes it can be positive also. For example, one may feel that his Caste is better than other Castes. Very often such prejudices are found when it comes to women in one’s Caste.
