Abstract
Obstacles in crossed categorization effectiveness for the reduction of intergroup bias. Crossed categorization, in the way it has been carried out in most studies, has proved to have a clearer effect than the reduction of prejudice on crossed groups : the increase of prejudice against the double outgroup. In order to avoid this undesirable side effect, we have studied the effectiveness of another way crossed categorization can present itself, that is, the partial crossed categorization, which includes the double ingroup and a crossed group but not a double outgroup. This way of presentation has only been included in two studies, and no positive effects have been found. In this research, we propose the matching of shared features as a cognitive process which can make the intended effect of partial crossed categorization difficult. Results show that partial crossed categorization does not reduce prejudice against the crossed group.
