Subliminal messages are unidirectional communications invaluable to the receiver's consciousness that can influence their desire, behavior or conscious thought. Therefore, the mere existence of an effective subliminal message can be considered as manipulation: an illegal intervention in the action of others by hidden means.

In the field of human communication, subliminal messages have a certain relationship with non-verbal communication when we are before our interlocutor. Non-verbal communication includes facial gestures and body choreography, tone of voice, rhythm, speed or timbre; subtle gestures of the face or hands, weak changes of posture, a light or penetrating look that accompanies words. According to students, most of the information is transmitted through face-to-face contacts. Today, in written communication (especially in short chat messages) there has been an increase in pictograms that mimic facial expressions, through which we transmit moods; prestige emoticons.

Apparently, when they started researching nonverbal language, they did it thinking about commercials, executives and executives. We are gradually approaching the issue. This is clearly noted in the election campaigns, which are mainly public reports about candidates (propaganda images, looking at remoteness with metaphysical depth or smiling in camera with high self-esteem and safety).

Advertising uses all means at its disposal to sell products, any product. "Sell" here we can understand it verbally or deferred, as the objective is to generate a favorable opinion for a product that is sold literally in the medium or long term. Both covert and subliminal advertising are expressly prohibited. In the latter case, illegality affects its hard version, that is, the techniques that incorporate stimuli that we do not perceive. But apart from that, the soul of the most sophisticated advertising is precisely the issuing of non-explicit suggestions and indirect messages. Through colours, forms and words of double meaning, very chosen melodies, suggestive voices of great sex appeal, etc., he manages to create in the receiver positive associations and predispositions in favour of the product he wants to sell (this, I admit, does not serve as an explanation in the case of radio advertising ads and intruders, whose mechanisms of influence I cannot understand).

Some constants that constantly appear in the pedagogical discourse for innovation have made me think about all these issues. For example, when they say that theirs is “cooperative”, “active” or “inclusive” teaching, or “student-centered” teaching, “personalized” teaching… what messages are actually being transmitted below? Yes, I'm asking which subliminal messages are transmitting to our emotional side, maliciously, trying to circumvent the filters of critical rationality. Because I think when you present your proposals as "active learning," for example, you're suggesting that the rest is passive learning. But the truth is, there's no learning that can be passive. Well, with all this. What's called "new school," it's long been old. His arguments are against a school that did not exist decades ago. We need less disguised emotional advertising and more rational debates, a wolf.
