A prejudice is an opinion, prejudgment or attitude about a group or its individual members. A prejudice can be positive, but in here it refers to a negative attitude.
Prejudices are often accompanied by ignorance, fear or hatred. Prejudices are formed by a complex psychological process that begins with attachment to a close circle of acquaintances or an "in-group" such as a family. Prejudice is often aimed at "out-groups."Discrimination is behavior that treats people unequally because of their group memberships. Discriminatory behavior, ranging from slights to hate crimes, often begins with negative stereotypes and prejudices.
