Social representations containing "mute areas" cannot be fully understood. The "mute zones" convey "subsystems of beliefs or cognitions which are not expressed spontaneously by subjects in usual circumstances, because of the normative pressures exerted on them". Impossible to be revealed by the classical methodology of data collection, the constituent elements of the zones mentioned above, illustrate by excellence the intimate conviction of the individual. Strongly rooted in the obscure sub-layers of the ontogenetic act, they are what "is forbidden" or, in other words, what embodies "a minor point of view opposed to the major attitudinal stream". As a result of their intercession, there is a "masking" of certain portions of the representational space (the masking effect), of certain portions that represent, and as a matter of fact, the real attitude of the subject towards the object of the representation. The attention, with which the "mute zones" of the social representation have been lately considered, is far by being accidental. On one hand, it indicates that we assist at a r revival evidence of researches that aim the problem of the "reading grids of the reality". On the other hand, the same attention proves that an investigational track has finally appeared, through which hidden elements of the mentioned grids can be outlined, elements which cannot constitute the object of the classical models of collecting experimental data. The importance of shaping all these elements is even greater as they, according to what specialist say, "are linked especially to certain 'sensible social objects', which could not be studied in depth in different circumstances and on different occasions".
