There are three main approaches to this strategy. The first approach is decategorization and uses differentiation and categorization to abolish categorization. Biases are reduced by making the interaction more external to the group than internal. Although individual interaction produces much better results than task focus, it is not possible to directly generalize about individuals and the group as the strategies involved in individual approaches will disrupt group interaction. According to a survey, having out-group friends reduces prejudice and therefore this supports this strategy. Another approach is recategorization which involves altering existing categories (us and them) and replacing them with new superordinate categories (us). Maintaining the salience of category distinctions is another approach and is based on two main aspects which are: (a) maintaining the salience of group boundaries when in contact so as to encourage generalization among members of the target outgroup ; (b) mutual differentiation between groups which will be the result of the difference in skills and experience of the
