Professor Maximilien Ringelmann observed, in tug-of-war experiments, that two people performed at around 93% of their individual capacity, three people reached approximately 85%, but groups of eight people barely reached 49%. This paradox is significant, since a larger team brings together more potential talent, accomplishes less actual work, and requires greater coordination. In a decision of this kind, it is more important to understand how each person contributes than how many people are involved. The Ringelmann effect offers a valuable lesson for education, science, politics, and team management, because while adding people expands capabilities, it can also dilute individual effort when responsibility becomes diffuse.
Nearly a century later, another group of researchers, led by Alan Ingham, replicated the phenomenon with groups of up to six members and determined (similarly) that individual performance decreased when moving from individual to group work, and that losses occurred when each participant acted alone while believing they were collaborating with others. Part of the effect stems from coordination, and another part from motivation and perceived responsibility. This pattern has been confirmed in other studies, reinforcing the conclusion that "social loafing" appears in various tasks, modulated by the visibility of effort and the clearly defined objective of the task.
However, interpreting the Ringelmann effect as a condemnation of teamwork is an incomplete understanding. Just a few years ago, Weber and Hertel discovered that lower-performing members increased their motivation when their contribution was indispensable, and that performance improved when group goals were specific and demanding rather than vague. A team can reduce or multiply effort; the difference lies in its structure.
Let's consider six students tasked with reducing their university's electricity consumption. If each student takes on a verifiable responsibility (measurement, data collection, cost analysis, design, environmental impact assessment, and communication) and the group then compiles the evidence, the collaboration becomes structured. The same logic applies to a research setting, where each member must know what they are analyzing, what evidence they are contributing, and what decision they are helping to support.
The Ringelmann effect encourages the design of formal and informal organizations, large or small, where collaboration means contributing through specific roles, shared goals, contrasting perspectives, and subsequent review. Collective intelligence flourishes when the group makes its efforts visible and transforms each contribution into a necessary piece of the solution. This principle applies to science, politics, and the everyday pursuit of our social goals.

Excellent lines…applicable to work teams for their analysis, understanding and application.
