How does the size of a team impact indi­vid­ual per­for­mance? The Ringel­mann effect sug­gests that indi­vid­ual pro­duc­tiv­i­ty decreas­es as the size of a group increas­es, lead­ing some to assume that larg­er teams result in lazier employ­ees. In sim­ple terms, peo­ple tend to put in less effort when they work togeth­er in a large group com­pared to when they work alone or in small­er groups. But what are the under­ly­ing caus­es, and how can orga­ni­za­tions address them?

The effect was first observed by a French agri­cul­tur­al engi­neer named Max Ringel­mann in the ear­ly 1900s dur­ing a series of exper­i­ments. He noticed that when peo­ple pulled on a rope as a team, the total force exert­ed by the group was less than the sum of the indi­vid­ual efforts.

While the Ringel­mann effect has been empir­i­cal­ly demon­strat­ed in mod­ern teams, there are still some mis­con­cep­tions about its caus­es. In man­age­ment cir­cles, it is wide­ly believed that the pri­ma­ry rea­son for this per­for­mance loss is social loaf­ing, where­in indi­vid­u­als hide in larg­er groups and become lazy. Although this phe­nom­e­non undoubt­ed­ly exists, the expla­na­tion is not that simple.

The main rea­sons for the Ringel­mann effect are believed to be a com­bi­na­tion of three factors:

1. Coor­di­na­tion issues: Larg­er teams often face chal­lenges in orga­niz­ing and coor­di­nat­ing their efforts, lead­ing to reduced indi­vid­ual productivity.
2. Social loaf­ing: In larg­er groups, indi­vid­u­als may feel that their con­tri­bu­tions are less vis­i­ble or sig­nif­i­cant, so they put in less effort, assum­ing oth­ers will com­pen­sate for their reduced input.
3. Moti­va­tion and account­abil­i­ty: In big teams, it can be hard­er to keep every­one moti­vat­ed and hold each mem­ber account­able for their tasks, result­ing in decreased effort.

A consequence of reduced self-efficacy?

Let’s take a look at some stud­ies that can pro­vide more insight into these caus­es and, more impor­tant­ly, poten­tial solu­tions for organizations:

Shaw (1960) sug­gest­ed that one’s moti­va­tion is direct­ly relat­ed to the pro­por­tion­al share of one’s con­tri­bu­tion to the group prod­uct, which implies a con­nec­tion between the Ringel­mann effect and self-effi­ca­cy. Self-effi­ca­cy refers to an indi­vid­u­al’s belief in their abil­i­ty to suc­cess­ful­ly per­form a task or achieve a goal.

In larg­er groups, indi­vid­u­als may per­ceive their con­tri­bu­tions as less sig­nif­i­cant or less like­ly to make a mean­ing­ful impact on the over­all group out­come. This per­cep­tion could lead to a decrease in self-effi­ca­cy, caus­ing indi­vid­u­als to feel less con­fi­dent in their abil­i­ties and less moti­vat­ed to put in their best effort.

«Indus­tri­al­iza­tion has made mod­ern man feel that he is a ‹small cog in a great machine› and has thus tend­ed to alien­ate mod­ern man from his work.»

In this con­text, the Ringel­mann effect can be seen as a con­se­quence of reduced self-effi­ca­cy in larg­er groups. To mit­i­gate this, it’s cru­cial to cre­ate an envi­ron­ment where team mem­bers feel val­ued and rec­og­nize the impor­tance of their con­tri­bu­tions, regard­less of the group size. Encour­ag­ing open com­mu­ni­ca­tion, set­ting clear goals, and fos­ter­ing a sense of indi­vid­ual respon­si­bil­i­ty can help improve self-effi­ca­cy and, in turn, coun­ter­act the Ringel­mann effect.

Fol­low­ing the Shaw study, anoth­er influ­en­tial research con­duct­ed by Latane, Williams, and Harkins (1979) fur­ther explored the con­cept of social loaf­ing. In their exper­i­ments, par­tic­i­pants were asked to per­form phys­i­cal­ly exert­ing tasks, such as clap­ping and shout­ing, either indi­vid­u­al­ly or in groups. The researchers found a sig­nif­i­cant decrease in indi­vid­ual effort when par­tic­i­pants per­formed in groups com­pared to when they per­formed alone. This decrease, referred to as social loaf­ing, occurred beyond the loss­es result­ing from faulty coor­di­na­tion of group efforts. The study high­lights the impor­tance of under­stand­ing and address­ing social loaf­ing in the con­text of the Ringel­mann effect. By iden­ti­fy­ing the con­di­tions that min­i­mize social loaf­ing, orga­ni­za­tions can take steps to ensure indi­vid­ual efforts are main­tained and group per­for­mance remains strong.

Why group goals play an essential role

Two addi­tion­al exper­i­ments from 1989 offer inter­est­ing insights for orga­ni­za­tions: Harkins and Szy­man­s­ki found that when a stan­dard was pro­vid­ed for the group to eval­u­ate its per­for­mance, the social loaf­ing effect was elim­i­nat­ed. This sug­gests that being able to assess the group’s per­for­mance and com­pare it to a giv­en stan­dard can moti­vate indi­vid­u­als to put in more effort, thus coun­ter­act­ing the neg­a­tive effects of social loafing.

One more study worth exam­in­ing: Wel­don, Jehn, and Prad­han (1991) found that set­ting spe­cif­ic goal lev­els had a strong impact on group per­for­mance, which was medi­at­ed by fac­tors such as effort, indi­vid­ual strat­e­gy change, group plan­ning, group strat­e­gy change, and con­cern for qual­i­ty. The study also iden­ti­fied oth­er vari­ables that influ­enced group per­for­mance, includ­ing ini­tial per­for­mance on the task, unplanned devi­a­tions from estab­lished work roles, and per­for­mance monitoring.

«Groups make pos­si­ble the achieve­ment of many goals that indi­vid­u­als alone could not pos­si­bly accomplish»

These find­ings sug­gest that group goals play an essen­tial role in shap­ing group process­es and per­for­mance. Fur­ther­more, the study high­lights the impor­tance of indi­vid­ual plan­ning, strat­e­gy changes, spon­ta­neous behav­iors, and per­for­mance mon­i­tor­ing in group performance.

In the con­text of the Ringel­mann effect, this study’s find­ings imply that set­ting clear group goals and estab­lish­ing effec­tive group process­es could help coun­ter­act the neg­a­tive effects of social loaf­ing and improve over­all group performance.

What organizations can do

In sum­ma­ry, the Ringel­mann effect is a com­plex phe­nom­e­non that can be attrib­uted to a com­bi­na­tion of fac­tors such as coor­di­na­tion issues, social loaf­ing, moti­va­tion, and account­abil­i­ty. To coun­ter­act the Ringel­mann effect, orga­ni­za­tions can imple­ment the fol­low­ing strategies:

1. Cre­ate an envi­ron­ment where team mem­bers feel val­ued: Encour­age open com­mu­ni­ca­tion, rec­og­nize indi­vid­ual achieve­ments, and pro­vide reg­u­lar feed­back. This will help team mem­bers feel more engaged and com­mit­ted to the team’s success.
2. Set clear goals and per­for­mance bench­marks: Clear­ly define the objec­tives and expec­ta­tions for each team mem­ber and the group as a whole. This allows indi­vid­u­als to under­stand their roles and respon­si­bil­i­ties and helps them stay focused on their tasks.
3. Estab­lish effec­tive group process­es: Devel­op well-defined work­flows, assign respon­si­bil­i­ties, and ensure that every­one under­stands the steps involved in com­plet­ing a task. Effi­cient group process­es can reduce con­fu­sion and improve over­all productivity.
4. Pro­mote indi­vid­ual plan­ning and strat­e­gy changes: Encour­age team mem­bers to plan their work, set per­son­al goals, and adapt their strate­gies as need­ed. This fos­ters a sense of own­er­ship and respon­si­bil­i­ty, which can lead to high­er indi­vid­ual performance.
5. Encour­age spon­ta­neous behav­iors and per­for­mance mon­i­tor­ing: Allow for flex­i­bil­i­ty and adapt­abil­i­ty with­in the team. Encour­age team mem­bers to take ini­tia­tive, adapt to chang­ing cir­cum­stances, and mon­i­tor their own per­for­mance. This can lead to increased inno­va­tion and improved group performance.

By address­ing these fac­tors, orga­ni­za­tions can reduce the neg­a­tive impact of the Ringel­mann effect and enhance over­all group performance.

Most impor­tant­ly, it is essen­tial not to demo­nize groups but rather to rec­og­nize their val­ue, as Latane, Williams, and Harkins have point­ed out: «The ‹cure,› how­ev­er, is not to do away with groups, because despite their inef­fi­cien­cy, groups make pos­si­ble the achieve­ment of many goals that indi­vid­u­als alone could not pos­si­bly accom­plish. Col­lec­tive action is a vital aspect of our lives: From time immemo­r­i­al it has made pos­si­ble the con­struc­tion of mon­u­ments, but today it is nec­es­sary to the pro­vi­sion of even our food and shel­ter. We think the cure will come from find­ing ways of chan­nel­ing social forces so that the group can serve as a means of inten­si­fy­ing indi­vid­ual respon­si­bil­i­ty rather than dif­fus­ing it.»
