Bravo to the young men who ran in and triggered this particular herd action. They simply step in and take action, others see what they are doing and are inspired with confidence to do the same. It's quite extraordinary how swiftly this unusual situation, which could have become a messy kind of tragedy, is turned around.
It's a reminder of how our choices and actions can influence those around us.
On March 5th 2012, in Arraial do Cabo, Brazil, about 30 dolphins washed up ashore stranded on a beach only to be saved by beach goers and tourists. From the clip you see one or two people start to drag the dolphins back into the water. It doesn’t take long before more people come along and each grab a dolphin.
All of the dolphins are saved in less than 4 minutes.
Herd mentality, or mob mentality, describes how people are influenced by their peers to adopt certain behaviors, follow trends, and or take action. This video is a prime example how the the initial actions of two people triggered a "herd" response from the bystanders. This in itself highlights how your own behavioral tendencies and the choices you make everyday are examples of how small change at one place in a deterministic nonlinear system can result in large differences in a later state.
It's more than the butterfly effect of chaos theory; its human nature.
