Social loafing


In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals. Research on social loafing began with rope pulling experiments by Ringelmann, who found that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members feeling their individual effort will not matter to the group.
Max Ringelman, a French professor of agricultural engineering, demonstrated in the 1890s the concept of social loafing. Ringelman, who was also considered one of the founders of social psychology, made people pull on ropes both separately and in groups and measured and compared how hard they pulled. After collecting the results he realized that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members feeling that his or her effort will not matter to the group. This is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals, but should be distinguished from the accidental coordination problems that groups sometimes experience.
Several studies found the most prevalent motivational origins of social loafing to be the lack of an understanding of individual contributions, unchallenging tasks given to the individual, low personal satisfaction from the task, and lack of a united group. Theories investigating why social loafing occurs range from group members feeling that their contributions will not be noticed to group members realizing their efforts are not necessary. In a work setting, most managers agree if a task is new or complex employees should work alone. While tasks that are well known and have room for individual effort are better when done in groups.
In order to diminish social loafing from a group, several strategies could be put forward. Social loafing primarily happens when an individual unconsciously or consciously exerts less effort due to a decrease in social awareness. In order to counteract the likelihood of this happening, Miguel Herraez conducted a study on students where he used accountability and cooperation when unequal participation is found. The students were encouraged to provide equal participation in the work and to point out sources of conflict that could arise. The conclusion of the study found that providing support to the group members lacking in commitment and creating options for independence among group members lowered social loafing. The support for the weaker students improves their standing while also benefiting the other students.
Social loafing should be distinguished from the accidental coordination problems that groups sometimes experience.

History

Rope-pulling experiments

The first known research on the social loafing effect began in 1913 with Max Ringelmann's study. He found that, when he asked a group of men to pull on a rope, they did not pull as hard collectively as they did when each was pulling alone. This research did not distinguish whether this was the result of the individuals in a group putting in less effort or of poor coordination within the group. In 1974, Alan Ingham, James Graves, and colleagues replicated Ringelmann's experiment using two types of group: 1) Groups with real participants in groups of various sizes Pseudo-groups with only one real participant. In the pseudo-groups, the researchers' assistants only pretended to pull on the rope. The results showed a decrease in the participants' performance. Groups of participants who all exerted effort exhibited the largest declines. Because the pseudo-groups were isolated from coordination effects, Ingham proved that communication alone did not account for the effort decrease, and that motivational losses were the more likely cause of the performance decline.

Clapping and shouting experiments

In contrast with Ringelmann's first findings, Bibb Latané, et al., replicated previous social loafing findings while demonstrating that the decreased performance of groups was attributable to reduced individual effort, as distinct from a deterioration due to coordination. They showed this by blindfolding male college students while making them wear headphones that masked all noise. They then asked them to shout both in actual groups and pseudogroups in which they shouted alone but believed they were shouting with others. When subjects believed one other person was shouting, they shouted 82 percent as intensely as they did alone, but with five others, their effort decreased to 74 percent.
Latané, et al., concluded that increasing the number of people in a group diminished the relative social pressure on each person: "If the individual inputs are not identifiable the person may work less hard. Thus if the person is dividing up the work to be performed or the amount of reward he expects to receive, he will work less hard in groups."

Meta-analysis study and the Collective Effort Model (CEM)

In a 1993 meta-analysis, Karau and Williams proposed the Collective Effort Model , which is used to generate predictions. The CEM integrates expectancy theories with theories of group-level social comparison and social identity to account for studies that examine individual effort in collective settings. From a psychological state, it proposes that Expectancy multiplied by Instrumentality multiplied by Valence of Outcome produces the resulting Motivational Force.
Karau, et al., concluded that social loafing occurred because there was usually a stronger perceived contingency between individual effort and valued outcomes when working individually. When working collectively, other factors frequently determine performance, and valued outcomes are also divided among all group members. All individuals are assumed to try to maximize the expected utility of their actions. The CEM also acknowledges that some valued outcomes do not depend on performance. For example, exerting strong effort when working on intrinsically meaningful tasks or with highly respected team members may result in self-satisfaction or approval from the group, even if the high effort had little to no impact on tangible performance outcomes.
Notable or novel findings by Karau and Williams following their implementation of the CEM include:
A 2005 study by Laku Chidambaram and Lai Lai Tung based their research model on Latané's social impact theory, and hypothesized that as group size and dispersion grew, the group's work would be affected in the following areas: Members would contribute less in both quantity and quality, final group output would be of lower quality, and a group's output would be affected both by individual factors and contextual factors.
A sample of 240 undergraduate business students was randomly split into forty teams which were randomly assigned to either a co-located or distributed setting. The participants were to complete a task that asked them to act as a board of directors of a winery with an image problem. They were to find and discuss alternatives, and at the end submit their alternative with rationale. Co-located groups worked at a table together, while distributed groups did the same task at separate computers that allowed for electronic, networked communication. The same technology was used by both co-located and distributed groups.
Chidambaram and Tung found that group size mattered immensely in a group's performance. The smaller the group, the more likely each member was to participate, regardless of range. The main difference stated between distributed and co-located groups was the social pressure at least to appear busy that is present in co-located groups. When others are present, people feel the need to look as if they are working hard, while those who are not in the presence of others do not.

Gender and social loafing

In 1985, Gabrenya, Wang, and Latane found that in both Chinese and American cultures, social loafing varies between men and women. Women expressed less social loafing than men across different cultures. The authors argued that regardless of the change in social roles, genetic and historical roles continue to make men more individualistic and women more relational.
In 1999, Naoki Kughiara conducted another study in Japan on social loafing tendencies using similar methods as Max Ringelmann's rope-pulling experiment. He discovered that, when in a group, 40 percent more men exhibited less effort when performing the task than women, and attributed the difference to the tendency to have an interdependent self-concept.

Effect of culture

In 1989, Christopher P. Earley hypothesized that social loafing would be mitigated in collectivist cultures that focused more on achievement of the group than the individual. He conducted a study in the United States and China, which are considered to be opposites in their cultural valuation of groups, in order to determine if a difference in social loafing was present between the two cultures. Earley formed groups from both countries similar in demographics and in time spent with each other. Each group was tasked with completing various forms of paperwork similar to work they would be required to do in their profession. The paperwork was designed to take two to five minutes for each item, and the items were turned in to an assistant when completed so that no one could judge their work compared to others. Each participant was given 60 minutes to complete as many items as possible and was separated into either the high-accountability group, where they were told they needed to achieve a group goal, or a low-accountability group, where they were told they were to achieve a goal alone. They were also separated into high and low shared responsibility groups.
It was found that, consistent with other studies, highly individualistic people performed more poorly on the task when there was high shared responsibility and low accountability than when there was high accountability. The collectivists, however, performed somewhat better on the task when high shared responsibility was present, regardless of how accountable they were supposed to be as compared to when they were working alone. This evidence suggests that collectivist thinking reduces the social loafing effect. Further evidence from a similar study showed the effect was related to the collectivist thinking rather than nationality, as individualistic Chinese workers did indeed show a social loafing effect.

Causes

Diffusion of responsibility

As the number of people in the group or team increase, people tend to feel deindividuation. This term defines both the dissociation from individual achievement and the decrease of personal accountability, resulting in lower exerted effort for individuals in collaborative environments. This phenomenon can thus decrease overall group effectiveness because it is contagious and hard to correct. Once identified by the group or team leader, it is their responsibility to reassess and put into motion new rules and expectations for everyone.
People could simply feel "lost in the crowd", so they feel that their effort would not be rewarded even if they put it forth. This idea can also cause people to feel as though they can simply "hide in the crowd" and avoid the averse effects of not applying themselves.
When enthusiasm for the overall goal or task is diminished, overall contribution will drop. When one feels that their overall efforts are reduced or unimportant, they will likely become social loafers.
Motivation:
Social psychological literature has found that the level of motivation one has to engage in an activity influences one's behavior in a group setting. This finding, deemed the collective effort model by Karau and Williams details that individuals who are more motivated are more likely to engage in social facilitation whereas those who are less motivated are more likely to engage in social loafing. Researchers have determined that two factors which determine an individual's motivation, and subsequently whether or not the individual will resort to social loafing versus social facilitation, include the individual's expectations about attaining the goal and the perceived value of the goal.
Thus, a person's attitude toward these two factors will influence his or her motivation level and subsequent group behavior. Karau and Williams found that motivation was highest when the individual believed that the goal was easily attainable and very valuable. On the other hand, motivation was lowest when the goal seemed impossible and not at all valuable.
Unfortunately, the presence of a group can influence one's perception of these two factors in a number of ways. For instance, working in a group may reduce or increase one's expectancy of attaining a goal. That is, depending on the qualities of the group members, an individual may find herself in a group of high achievers who work hard and are guaranteed success, whereas another may equally find himself in a group of lazy or distracted people, making success seem unattainable. Therefore, the link between one's personal efforts and success is not direct, as our success is influenced by the work of others. Similarly, the value of the goal may be contingent on the group members. For instance, if we must share success with all other group members, then the value of the goal is reduced compared to the value of the goal from an individual perspective. Hence, the dynamic of the group is an important key in determining a person's motivation and the likelihood of social loafing. Additional factors which have been found to influence the likelihood of social loafing include one's gender, cultural background, and the complexity of the task.

Dispensability of effort

When a group member does not feel that his or her effort is justified in the context of the overall group, the individual will be less willing to expend the effort. If the group size is large, members can feel that their contribution will not be worth much to the overall cause because so many other contributions can or should occur. This leads people to not contribute as much or at all in large groups as they might have in smaller groups.
One example is voting in the United States. Even though most people say that voting is important, and a right that should be exercised, every election a sub-optimal percentage of Americans turn out to vote, especially in presidential elections. One vote may feel very small in a group of millions, so people may not think a vote is worth the time and effort. If too many people think this way, there is a small voter turnout. Some countries enforce compulsory voting to eliminate this effect.

"Sucker" effect/Aversion

Some people feel that others in the group will leave them to do all the work while they take the credit. Because people do not want to feel like the "sucker", they wait to see how much effort others will put into a group before they put any in. If all the members try to avoid being the sucker, then everyone's effort will be significantly less than it would be if all of them were working as hard as they could.
For example, in a workplace environment, the establishment of an absence culture creates an attitude that all employees deserve to have a certain number of days of absence, regardless of whether or not they are actually sick. Therefore, if an employee has not used the maximum number of absence days, "he may feel that he is carrying an unfair share of the workload".

Attribution and equity; matching of effort

Jackson and Williams proposed that if someone feels that others in the group are slacking off or that others will loaf, he will lower his effort to match that of the others. This can occur whether it is apparent that the others are slacking or if someone simply believes that the group is slacking. For example, in the Latane, et al., study above, if a participant heard the others making less noise than anticipated, he could have lowered his effort in an attempt to equal that of the others, rather than aiming for the optimum.

Submaximal goal setting

By setting a goal that is based on maximization, people may feel that there is a set level that the group needs to be achieved. Because of this, they feel that they can work less hard for the overall desired effect.
For example, in the Latane et al. clapping and shouting study, people who were alone but told that they were part of a group screaming or clapping could have thought that there was a set level of noise that experimenters were looking for, and so assumed they could work less hard to achieve this level depending on the size of the group.

Non-Involvement

Non-Involvement Social loafing has been linked to people the non-involvement of the members within the group Studies have shown that groups where the members were not personally involved in the project had a higher chance to experience social loafing. When members of group can bring a contribution that is unique and that complements the project, loafing is highly unlikely to occur. That contribution could be considered unique, if each member had a specific task that only he or she could and would do that would contribute to the completion of the project. Authors from Texas Wesleyan University confirmed that : “ Individuals are less likely to loaf when they feel the contribution is unique, and no other group member can contribute the skills to the task that they can.” Furthermore, when the project has a personal meaning to them, they are more involved and do not practice social loafing

Real-life instances

1994 Black Hawk shootdown incident

On April 14, 1994, two U.S. Air Force F-15 fighters accidentally shot down two U.S. Army Black Hawk helicopters over northern Iraq, killing all 26 soldiers on board. The details of the incident were analyzed by West Point Professor Scott Snook in his book Friendly Fire.
In his summary of the fallacy of social redundancy, Snook points to social loafing as a contributor to the failure of the AWACS aircraft team to track the helicopters and prevent the shootdown. Snook asserts that responsibility was "spread so thin by the laws of social impact and confused authority relationships that no one felt compelled to act".

Social loafing and the workplace

According to Hwee Hoon Tan and Min-Li Tan, social loafing is an important area of interest in order to understand group work. While the opposite of social loafing, "organizational citizenship behavior", can create significant productivity increases, both of these behaviors can significantly impact the performance of organizations. Social loafing is a behavior that organizations want to eliminate. Understanding how and why people become social loafers is critical to the effective functioning, competitiveness and effectiveness of an organization.
There are certain examples of social loafing in the workplace that are discussed by James Larsen in his essay "Loafing on The Job". For example, builders working vigorously on a construction site while some of their colleagues are lounging on rock walls or leaning on their shovels doing nothing. Another example is a restaurant such as McDonald's where some employees lounge about while others are eager to take an order. These scenarios all express the problems that social loafing creates in a workplace, and businesses seek to find a way to counteract these trends.
Larsen mentions ways that a business could change its operations in order to fight the negative effects of social loafing. For one, research has shown that if each employee has his performance individually measured, he will put in more effort than if it were not measured. Another person interested in the idea of social loafing is Kenneth Price, from the University of Texas. Price conducted a social loafing experiment in order to examine whether two key factors that he suspected played a role in the way social loafing arose in work groups. These two factors were dispensability and fairness. The experiment that he conducted involved 514 people who were divided into 144 teams that were set to meet for fourteen weeks. The projects assigned to these people were complex and called for diverse skills from many different individuals in order to be fully completed. The experiments findings did in fact corroborate Price's suspicions in the two factors of dispensability and fairness.
Dispensability in a group is described by Price as employees who join a work group and quickly begin to gauge their skills vis à vis their co-workers. If they perceive that their skills are inferior to those around them, they tend to sit back and let the more skilled workers carry the workload. Fairness in a group is when some group members feel that their voice is not heard in decision-making because of their ethnicity, gender or other arbitrary factors. Instead of fighting for their voice to be heard many group members will decide to loaf in these circumstances.

Online communities and groups

Research regarding social loafing online is currently relatively sparse, but is growing.
A 2008 study of 227 undergraduate and graduate students enrolled in web-enabled courses at the Naval War College and a public university found that social loafing not only exists, but may also be prevalent in the online learning classroom. Although only 2 percent of NWC and 8 percent of public university students self-reported social loafing, 8 percent of NWC and 77 percent of public university students sensed that others engaged in social loafing. Additional findings generally verify face-to-face social loafing findings from previous studies. The researchers concluded that injustice in the distribution of rewards increases social loafing, and suggest that self-perceived dominance negatively affects individual participation in group activities.
Social loafing, also known as "lurking", greatly affects the development and growth of online communities. The term social loafing refers to the tendency for individuals to expend less effort when working collectively than when working individually. This phenomenon is much like people's tendency to be part of a group project, but rely heavily on just a few individuals to complete the work. Generally, social loafers regularly follow the discussions and content of online communities, but choose not to expand on posts or add to the knowledge of the community. Additionally, participation in online communities is usually voluntary; therefore there is no guarantee that community members will contribute to the knowledge of the website, discussion forum, bulletin board, or other form of online engagement. Lurkers are reported to constitute over 90 percent of several online groups.
The main reason people choose not to contribute to online communities surprisingly does not have to do with societal laziness, but in fact the potential contributors belief that their entries will not be taken seriously or given the credit that they deserve. When people assess the risks involved in contributing to online communities, they generally avoid participation because of the uncertainty of who the other contributors and readers are and the fear of their work being undervalued.

Age-related effects on participation

Although studies justify the notion that people often do not contribute to online communities, some research shows that older adults are more likely to participate in online communities than younger people because different generations tend to use the internet differently. For example, "older adults are more likely to seek health information, make purchases, and obtain religious information, but less likely to watch videos, download music, play games, and read blogs online". This is perhaps due in part to the fact that some online communities cater to older generations. The content of the website often determines what age group will use or visit the site, and because many forms of online communities appear on sites that focus their attention on older adults, participation is generally higher. Additionally, the ease and availability of operating the websites that host the online community may play a role in the age group that is most likely to participate. For example, some online communities geared toward older adults have simplified the design of their sites in order to enhance their look and usability for older adults.

Reduction

According to Dan J. Rothwell, it takes "the three Cs of motivation" to get a group moving: collaboration, content, and choice. Thus, the answer to social loafing may be motivation. A competitive environment may not necessarily motivate group members.
  1. Collaboration is a way to get everyone involved in the group by assigning each member special, meaningful tasks. It is a way for the group members to share the knowledge and the tasks to be fulfilled unfailingly. For example, if Sally and Paul were loafing because they were not given specific tasks, then giving Paul the note taker duty and Sally the brainstorming duty will make them feel essential to the group. Sally and Paul will be less likely to want to let the group down, because they have specific obligations to complete.
  2. Content identifies the importance of the individual's specific tasks within the group. If group members see their role as that involved in completing a worthy task, then they are more likely to fulfill it. For example, Sally may enjoy brainstorming, as she knows that she will bring a lot to the group if she fulfills this obligation. She feels that her obligation will be valued by the group.
  3. Choice gives the group members the opportunity to choose the task they want to fulfill. Assigning roles in a group causes complaints and frustration. Allowing group members the freedom to choose their role makes social loafing less significant, and encourages the members to work together as a team.
Thompson stresses that ability and motivation are essential, but insufficient for effective team functioning. A team must also coordinate the skills, efforts, and actions of its members in order to effectively achieve its goal. Thompson's recommendations can be separated into motivation strategies and coordination strategies:
Motivation strategiesCoordination strategies

  • Increase identifiability
  • Promote involvement
  • Reward team members for performance
  • Strengthen team cohesion
  • Increase personal responsibility
  • Use team contracts
  • Provide team performance reviews and feedback
  • Using single-digit teams
  • Having an agenda
  • Training team members together
  • Spending more time practicing
  • Minimizing links in communication
  • Setting clear performance standards

    • Motivational strategies

    Increase identifiability: Studies of social loafing suggest that people are less productive when they are working with others, but social facilitation studies have shown that people are more productive when others are present. If individuals in a group know one another, feel that their productivity or inputs are not identifiable, then social loafing is likely to occur. Alternatively, if individuals are anonymous and therefore unidentifiable, then social loafing may also be likely to occur.
    Minimize free riding: Free riding occurs when members do less work because some of the benefits accrue to others. As others contribute ideas, individuals may feel less motivated to work hard themselves. They see their own contributions as less necessary or less likely to have much impact. To eliminate these effects, it is important to make group members feel that their contributions are essential for the group's success. Additionally, it is less likely for someone to free-ride if they are in a small group.
    Promote involvement: Loafing is also less likely to occur when people are involved with their work, and when they enjoy working with others in groups. These are people who value both the experience of being part of a group, as well as achieving results. Also, challenging and difficult tasks reduce social loafing. Social loafing is also reduced when individuals are involved in group work and their rewards are received as a team, rather than individually.
    Strengthen team cohesion: The extent to which group members identify with their group also determines the amount of social loafing. This concept links with social identity theory in that that difference between a hard-working group and one that is loafing is the match between the group's tasks and its members’ self definitions. When individuals derive their sense of self and identity from their membership, social loafing is replaced by social laboring.
    Set goals: Groups that set clear, challenging goals outperform groups whose members have lost sight of their objectives. The group's goals should be relatively challenging, instead of being too easily accomplished. The advantages of working in a group are often lost when a task is so easy that it can be accomplished even when members of the group socially loaf. Thus, groups should set their standards high, but not so high that the goals are unattainable. Latham and Baldes assessed the practical significance of Locke's theory of goal setting by conducting an experiment with truck drivers who hauled logs from the forest to the mill. When the men were initially told to do their best when loading the logs, they carried only about 60 percent of the weight that they could legally haul. When the same drivers were later encouraged to reach a goal of hauling 94 percent of the legal limit, they increased their efficiency and met this specific goal. Thus, the results of this study show that performance improved immediately upon the assignment of a specific, challenging goal. Company cost accounting procedures indicated that this same increase in performance without goal setting would have required an expenditure of a quarter of a million dollars on the purchase of additional trucks alone. So this method of goal setting is extremely effective. Other research has found that clear goals can stimulate a number of other performance-enhancing processes, including increases in effort, better planning, more accurate monitoring of the quality of the groups work, and even an increased commitment to the group.
    Individual assessment In order to reduce social loafing, a company can always focus on assessing each members contribution rather than only examining the teams accomplishments as a whole. It is statistically proven that social loafers will tend to put in less effort because of the lack of external or internal assessment of their contributions. This leads to less self-awareness in the group because the team together is the only body evaluated.
    Peer Evaluation
    Peer Evaluation is considered a way of reducing social loafing because when group members are able to go over each other’s works and criticize or comment on them, it makes group members realize that they will be on the spot if they do not work on their project and that at the same time, there will be repercussions. That will encourage them to engage themselves more deeply into their work. Researchers like John Rich from Delaware State University said that “Peer evaluations can send a signal to group members that there will be consequences for non-participation.Members may be allowed to fire loafers, forcing them to have to work together in a new group”. To them, firing the loafers could be a consequence and this measure would decrease social loafing and make people take accountability.In this case, the author sees peer evaluation as a type of authority that will ensure that team members will not loaf. Peer Evaluation can also seen as a productive and an efficient way to give constructive feedback.There are several ways you can incorporate feedback, whether it is to have each member present the results of their work at intervals, conduct regular feedback sessions, or even having group members

    Encouraging contributions in online communities

    Piezon and Donaldson argue in a 2005 analysis that special attention should be paid to the physical separation, social isolation, and temporal distance associated with distance education courses, which may induce social loafing. In terms of group size, they assert that there is no significant gain in small groups larger than six unless the group is brainstorming, and that the optimal group size may be five members. Suggestions that they have for online groups include clarifying roles and responsibilities, providing performance data for comparison with other groups, and mandating high levels of participation consisting of attending group meetings, using the discussion board, and participating in chats.
    In a 2010 analysis of online communities, Kraut and Resnick suggest several ways to elicit contributions from users:
    In 2008, Praveen Aggarwal and Connie O'Brien studied several hundred college students assessing what factors can reduce social loafing during group projects. From the results, they concluded that there were three factors that reduce social loafing:
    Limiting the scope of the project: Instructors can reduce social loafing by either dividing a big project into two or more smaller components or replacing semester-long projects with a smaller project and some other graded work. Also, breaking up a big project into smaller components can be beneficial. For example, allocating responsibility so that each individual is spearheading certain aspects of a larger project ensures accountability and helps prevent social loafing.
    Smaller group size: Limiting the group size can make it harder for social loafers to hide behind the shield of anonymity provided by a large group. In smaller groups, each member will feel that their contribution will add greater value.
    Peer evaluations: Peer evaluations send a signal to group members that there will be consequences for non-participation. It has been found that as the number of peer evaluations during a project go up, the incidence of social loafing goes down.
