With just one person staring up, 40 percent of passersby stopped to stare with them. With two people, the proportion rose to 60 percent, The Locusts and the Bees 33 and with five it was up to 90 percent. His results conform beautifully with later discoveries about invisible leaders. Maybe Connecticutians are unduly gullible, but when I repeated the experiment on a busy street in Sydney, I found that Australians are equally gullible, or at least biddable. I made my leaders even less visible, having them melt away when the crowd became large enough, leaving a crowd that stared by itself.
After the experiments had been completed and the fish released (or eaten—his paper does not say which), Partridge and his helpers sat down to painstakingly measure the relative fish positions in more than twelve thousand frames of film. At the end, they discovered the key rules that permitted the school to move as a unit. There were just two, which each fish obeyed: follow the fish in front (if there is one*) and keep pace with the fish beside you. These two simple rules, expressed in various forms, are now known to underlie all sorts of complex group movements, from the wonderfully unified flashes caused by changes of shape or direction in schools of fish to the movements of flocks of birds, swarms of insects, and crowds of humans.
The result is a complex dynamic pattern with its own inherent stability, but also with the potential for evolution and growth. * To avoid confusion, we should note that the physical scientist’s meaning for the terms positive and negative feedback are not the same as those of a psychologist. To a psychologist, negative feedback is destructive and destabilizing, while positive feedback is good and desirable. To a physical scientist, the implications are usually the reverse.
