The Ringelmann Effect: Why Teams Get Lazier the Bigger They Get

Why does a five-person group project always feel like only two people are actually pulling the weight? The answer was discovered over a century ago, using nothing more than a rope. In this video, you'll learn how French engineer Max Ringelmann accidentally uncovered one of psychology's most replicated findings while testing farm equipment efficiency in 1913, why psychologists Bibb Latané, Kipling Williams, and Stephen Harkins proved the effect wasn't just about physical coordination, and why the one variable that reliably fixes it isn't motivation, it's identifiability. You'll see why rowing teams stay sharp while tug-of-war teams quietly coast, and why your office's group chats and committees are just Ringelmann's rope wearing different clothes.
