The Ringelman effect is a reduction in personal effort when working in a group. When a person acts alone, he gives his best, but if he performs a task together with others, he tries a little less. And the larger the group, the smaller the contribution of each of its members.
For the first time this effect was discovered by D. Kravitz, B. Martin. Ringelmann Rediscovered: The Original Article / Journal of Personality and Social Psychology French professor, agricultural engineer Max Ringelman. At the end of the 19th century, he conducted a series of experiments on labor productivity. During them, young students from the agricultural school were asked to pull a rope — first alone, and then in a group of 7 and 14 people.
Working alone, the men pulled the rope with an average force of 85.3 kg. When 7 and 14 people worked on the task, everyone's efforts decreased to 65 and 61.4 kg, respectively.
Ringelman considered the main reason for this effect to be a lack of coordination of actions. Several people cannot move synchronously: maximum tension and relaxation occur at different times, which ultimately reduces everyone's productivity.
However, a number of works devoted to the Ringelman effect or, in another way, social laziness refute this assumption.
The Ringelman effect also manifests itself when consistency of actions is not required to perform the work. Moreover, it arises even if there is no group at all, but the person believes that there is one.
In one experiment B. Latané, K. Williams, S. Harkins. Many Hands Make Light the Work: The Causes and Consequences of Social Loafing / Journal of Personality and Social Psychology recruited students and asked them to clap and shout with all their might. At first, the participants completed the task individually, then in groups of two and six people.
As scientists expected, as the number of people grew, everyone's personal productivity decreased. The two students shouted and clapped 66% of their capacity, and the six of them — only 36%.
It can be assumed that the participants tried less because the group was already making a lot of noise, and people thought that this was enough and they could not waste their energy in vain.
To rule this out, the scientists put soundproof headphones on the students and said that they would work in a group, but they would not hear their partners. In fact, there was no group, but people believed that they were acting as a team, and their productivity was declining. If the students thought they were shouting together, they completed the task at 82% of the possible intensity, and if they thought they were working with six, at 74%.
Thus, the Ringelman effect cannot be explained only by the lack of coordination. It is more likely that people in the group relax for other reasons. There are several theories as to why this is happening S. Karau, K. D. Williams. Social Loafing: A Meta‑Analytic Review and Theoretical Integration / Journal of Personality and Social Psychology .
Despite the fact that the Ringelman effect is characteristic of group work, it is quite possible to deal with it if we take into account the causes of social laziness and make efforts to correct the situation.
One meta-analysis suggested S. Karau, K. D. Williams. Social Loafing: A Meta‑Analytic Review and Theoretical Integration / Journal of Personality and Social Psychology a model of personal efforts in a team, which lists all the necessary conditions for the absence of social laziness. According to her, each team member needs to see the results of their work and understand what contribution they make to the productivity of the group. In addition, joint efforts should benefit the team and, last but not least, the individual personally.
Violation of one or more conditions will result in the Ringelman effect. For example, social laziness is often found in large companies, where each employee participates only in a small part of the production process. Since people do not understand how their work helps to produce a product and earn money, they have no motivation to try harder.
Considering these factors, we can identify several rules that will help reduce the Ringelman effect in the group:
The meta-analysis also noted that the effect of social laziness disappears when a person works on interesting and important things for himself. If people are genuinely passionate about their work and are confident in the value of results, working in a group will not make them try less.
