Based on their responses to a spontaneous evocation survey, we describe the limits of the search for a central core of social representations in the case of a social acute object. The results do not confirm the hypothesis of the salience of a central core of social representation, we infer a didactic perspective of "educations to" based on the alternative approach of the matrix core. We argue in what way it is suitable to structure «patterns of reasoning» opening up a didactic perspective by allowing the passage from a common and little questioned social thought, to the confrontation of rationalities.
