This text argues the possibility of de-information in informative processes as an intrinsic component of the human communication. Partially it is a normal phenomenon due to double selectivity: our perceptive apparatus picks up what is viable to perceive, and each subject picks up according to his own interests. The problems lies mainly in the excessive manipulation of information, implying more or less ostensive "imbecilizing" effects. It is the case of advertising that pretends to produce a type of very effective non perceived influence, since it is based in refined strategies of expert knowledge. It is fundamental to preserve the critical and self-critical environment in order to be possible to reduce e control the manipulative information.
