Often we don’t realize that our attitude toward something has been influenced by the number of times we have been exposed to it in the past. - Robert B. Cialdini

The powerful influence of filmed examples in changing the behavior of children can be used as therapy for various problems. Some striking evidence is available in the research of psychologist Robert O’Connor on socially withdrawn preschool children. We have all seen children of this sort, terribly shy, standing alone at the fringes of the games and groupings of their peers. O’Connor worried that a long-term pattern of isolation was forming, even at an early age, that would create persistent difficulties in social comfort and adjustment through adulthood. In an attempt to reverse the pattern, O’Connor made a film containing eleven different scenes in a nursery-school setting. Each scene began by showing a different solitary child watching some ongoing social activity and then actively joining the activity, to everyone’s enjoyment. O’Connor selected a group of the most severely withdrawn children from four preschools and showed them his film. The impact was impressive. The isolates immediately began to interact with their peers at a level equal to that of the normal children in the schools. Even more astonishing was what O’Connor found when he returned to observe six weeks later. While the withdrawn children who had not seen O’Connor’s film remained as isolated as ever, those who had viewed it were now leading their schools in amount of social activity. It seems that this twenty-three-minute movie, viewed just once, was enough to reverse a potential pattern of lifelong maladaptive behavior. Such is the potency of the principle of social proof.50 When

Parte de su fenomenal éxito se debía a su infatigable capacidad de trabajo y compromiso, pero no todo. Según los cronistas de aquel triunfo, Feldman nunca presionaba para lograr una venta a los potenciales clientes que se mostraban reticentes. En lugar de ello, introducía un toque sutil (y astuto) en su discurso que los guiaba con suavidad hacia esa decisión.

There's a critical insight in all this for those of us who want to learn to be more influential. The best persuaders become the best through pre-suasion - the process of arranging for recipients to be receptive to a message before they encounter it. To persuade optimally, then, it's necessary to pre-suade optimally. But how?

In part, the answer involves an essential but poorly appreciated tenet of all communication: what we present first changes the way people experience what we present to them next.
