In the study of human preferences, the effect of mere exposure has acquired more and more relevance.
Also known as the familiarity principle, this effect explains why, when we are exposed to a nervous stimulus several times, our response to it becomes more positive.

Robert Zajonc is one of the authors who have studied this particular psychological effect the most. Since the first research on the topic, in 1876, the presence of this preference was proven in the face of stimuli of different natures.
