In this short clip, social psychologist Robert Cialdini describes a Belgian experiment that examined how visual cues of togetherness influence spontaneous helping behavior. Participants, including 18‑month‑old infants, were shown photographs of household objects with either a single figure or two figures standing shoulder‑to‑shoulder. After the researcher deliberately spilled items on the floor, the rate of unprompted assistance was measured. The study found that exposure to the “togetherness” cue (two figures) caused roughly three times more subjects—including babies—to help, indicating that the propensity to assist when primed with social unity is a deep‑seated, primitive human tendency. A second speaker remarks that this suggests we are hard‑wired for such behavior.

There was a study done in Belgium. Researchers brought subjects into an experiment and showed them a series of photographs of household objects— toasters, blenders— and in the background of the photograph, there was a figure standing either alone— that was for a third of the subjects saw that— a third of the subjects saw 2 figures standing shoulder to shoulder together. In all of the cases, the researcher got up from the table and accidentally spilled a number of items onto the floor. Oh, my God. And the question is, which of the subjects get down on their knees, help the researcher pick up these scattered items on the floor spontaneously without being asked? And there's no question. If people have been put in mind of the concept of togetherness, they become more helpful. The subjects were 18 months old. They were babies. And this process is so fundamental, so primitive in us, that it works on 18-month-olds. All children, and 3 times as many of them help after they've been exposed to the concept of togetherness.
You can't help but conclude that this is just the way we are built.
