SOCIAL LOAFTING

SOCIAL LOAFTING

 

WHY TEAMS ARE LAZY
In 1913 Maximilian Ringelmann, a French engineer, studied the performance of horses. He concluded that the power of two animals pulling a coach did not equal twice the power of a single horse. Surprised by this result, he extended his research to humans. He had several men pull a rope and measured the force applied by each individual. On average, if two people were pulling together, each invested just 93% of their individual strength, when three pulled together, it was 85%, and with eight people, just 49%.

 

 

Science calls this the social loafing effect. It occurs when individual performance is not directly visible; it blends in to the group effort. It occurs among rowers, but not in relay races, because here, individual contributions are evident. Social loafing is rational behaviour: why invest all of your energy when half will do – especially when this little shortcut goes unnoticed? Quite simply, social loafing is a form of cheating of which we are all guilty even if it takes place unconsciously, just as it did with Ringelmann’s horses.

 

 

When people work together, individual performances decrease. This isn’t surprising. What is noteworthy, however, is that our input doesn’t grind to a complete halt. So what stops us from putting our feet up completely and letting the others do all the hard work? The consequences. Zero-performance would be noticed, and it brings with it weighty punishments, such as exclusion from the group or vilification. Evolution has led us to develop many fine-tuned senses, including how much idleness we can get away with and how to recognise it in others. Social loafing does not occur solely in physical performance. We slack off mentally, too.

 

 

For example, in meetings, the larger the team the weaker our individual participation. However, once a certain number of participants is involved, our performance plateaus. Whether the group consists of 20 or 100 people is not important – maximum inertia has been achieved. One question remains: who came up with the much-vaunted idea that teams achieve more than individual workers? Maybe the Japanese. Thirty years ago, they flooded global markets with their products. Business economists looked more closely at the industrial miracle and saw that Japanese factories were organised into teams.

 

 

This model was copied – with mixed success. What worked very well in Japan could not be replicated with the Americans and Europeans – perhaps because social loafing rarely happens there. In the West, teams function better if and only if they are small and consist of diverse, specialised people. This makes sense, because within such groups, individual performances can be traced back to each specialist.

 

 

Social loafing has interesting implications. In groups, we tend to hold back not only in terms of participation, but also in terms of accountability. Nobody wants to take the rap for the misdeeds or poor decisions of the whole group. A glaring example is the prosecution of the Nazis at the Nuremberg trials, or less controversially, any board or management team. We hide behind team decisions.

 

 

The technical term for this is diffusion of responsibility. For the same reason, teams tend to take bigger risks than their members would take on their own. The individual group members reason that they are not the only ones who will be blamed if things go wrong. This effect is called risky shift, and is especially hazardous among company and pension-fund strategists, where billions are at stake, or in defence departments, where groups decide on the use of nuclear weapons.

 

 

In conclusion: people behave differently in groups than when alone (otherwise there would be no groups). The disadvantages of groups can be mitigated by making individual performances as visible as possible. Long live meritocracy! Long live the performance society!
