The Captain Class: A New Theory of Leadership

by Sam Walker

In 1913, Ringelmann conducted an experiment in which he asked his students to pull on a rope, both individually and in groups, while he measured the force they exerted. The conventional view was that people in a group would have more power collectively than they did alone—in other words, adding people to the pulling group would have a multiplying effect on the force. But the results showed something surprising. While the force applied did grow with every new person added, the average force applied by each person fell. Rather than amplifying the power of individuals, the act of pulling as a team caused each person to pull less hard than they had when pulling alone. Later researchers coined a name for this phenomenon. They called it social loafing.
