Nowadays, the social construction of mental illness, a collective representation, is strongly influenced by the media. All representations of "dangerousness" experience a similar outcome going through different media canals: news services, documentary films, talk shows, dramas, films, and a few special programs produced to raise awareness. The closure of mental hospitals has made mentally ill people socially visible and present. However, this evolution has not reduced the fear of "occult involvement", a threat to common sense. Does a mad person share the ordinary representation of reality? In a perspective of social defence, the expert can be charged with the responsibility of the socially "occulted" behaviour. Such facts culturally reinforce the concept of dangerousness, enhance a selective reconstruction of facts using a simple cause-effect approach, and reinforce stigmatizing stereotypes.
