Ultimately this guide is about social influence in groups. But first, let's look at the structure and roles in groups, because the degree of influence groups have very often depend on these dimensions.

TASKS
Group tasks can be unitary (i.e., co-active--the members simultaneously perform similar behaviors; although MD&M include this one, by now you can see that I would NOT generally consider this a group task or co-actors even much of a group).

Tasks can be conjunctive (the results or productivity are determined by the weakest member); disjunctive (the results or productivity are determined by the strongest member); or additive (the results are the sum of individual performances).

A key issue is whether group tasks are interdependent, i.e., there is some kind of division of labor whereby different members enact different, more specialized behaviors that are interlocking. Groups tend to have more influence over their members when tasks are interdependent because members must rely upon each other more to achieve group goals.

A classic example of interdependence has been Eliot Aronson's jigsaw puzzle classroom, which has become more commonly known with variations as "cooperative learning."  In a jigsaw puzzle, all the pieces must be present and in the right place to put the puzzle together. What happens if we form students into groups and see that each group member has a separate piece of information that is required if the group is to complete its project (and perhaps win a prize)? Students cooperate more with one another.

Aronson contrasts classrooms with groups that stress interdependence with those having a total reliance upon individual achievement. He asserts that jigsaw classrooms facilitate cooperation among students and lessen ethnic barriers. Largely positive evidence supports this assertion. Aronson's most recent application of the jigsaw classroom is to prevent bullying, which has been implicated in several instances of explosive school violence.
 

GROUP SIZE

Group size has mixed effects. Having a larger group can facilitate performance OR it can create a process loss  (members perform below their potential). Larger groups perform better with disjunctive tasks, relying on stronger members. Individual performance levels can decline with group size (the classic Ringelmann effect) perhaps due to social loafing.

Social loafing is a familiar phenomenon to most of us. Picture putting in a lot of work on a project that results in an excellent group grade, including a terrific grade for the member who never showed up for meetings and who did virtually no work at all. Social loafing makes people angry. It also results in disparing comments about committees and teams.

However, little advance planning and last minute work marathons are what make the social loafer possible. By the time you realize that this individual will not do his or her share of the work but plans to share in the rewards, the project due date is at hand. Too late to complain effectively to the teacher or the boss. Better coordination and individual feedback can minimize social loafing. Teamwork can produce such really great achievements, it's worth our while to outwit the social loafer.

Larger groups tend to have less informal interaction and are viewed as "less friendly" by their members. In order to produce more friendly relations--or even to get something done, large groups may need to create smaller subgroups for many tasks. I found that large religious congregations were more likely to create "support groups" whose ostensible reason was to meet socio-emotional needs among congregants. However, congregations who created support groups also were better able to politically mobilize around goals that were important to them, such as lobbying on abortion or providing volunteers for a homeless shelter. This was because many of the bureaucratic skills required to create and maintain support groups could also be used for political organizing.

We have known for several decades that large aggregates (rather than groups) tend to fuel what is called "diffusion of responsibility." In emergencies, people are more willing to help if a few or even a single person is around than when several people are present. Partly this occurs because large groups foster a sense of "deindividualization."
 

Interdependent tasks in groups have several consequences. Oneof the most prominent consequences is the emergence of social roles. Social roles emerge from groups, from the specialized divisions of labor and interlocking positions that even the most rudimentary groups tend to create. In formal organizations, social roles become positions and people are recruited to fill them. In informal groups, after a period of time, members may want to recruit for specialized role positions too.

In fact, in nearly all cases, if there were no groups, we would not have social roles. Because most of us belong to many different groups, we occupy many different roles. When roles are arranged in a hierarchy, we have what are called stratified social systems. When roles conflict in a variety of ways, we have role conflict.

Minimally, a role is a set of rights, duties, and scripts (prescriptives and prerogatives) attached to a specific social position. Roles transcend individuals: anyone who occupies a specific role is expected to display a minimal level of its scripts and duties. Some role requirements are codified and formal, others are informal. Although latitude often exists in how to play a role, there are also usually minimal defining criteria.

Because we occupy so many roles, and because different people have different expectations for the same role, roles can create stress for several reasons.

First, roles become an important part of our self-identify. Many of our social roles reflect family, occupational (including student), national, and friendship roles.

Each role takes time, often considerable amounts of time. Each takes effort and there is always the possibility that the time and effort involved with one role will conflict with those required for other roles. This is the "soccer mom" plight, dashing from meeting to meeting, or from one set of duties to another. Or, if you prefer, "multitasking."

Different roles also provide different expectations for behavior. When people interact with family or friends, they are expected to embrace the "whole person," to do special things for family or friends (lend money, assist when ill) that they don't do for just anyone (particularism) and to share their emotions (affective behavior). What happens when a good friend at work is promoted to be your boss? Work relationships, especially those between role superiors and role subordinates are supposed to be affectively neutral  and universalistic ("fair," that is, everyone receives the same kind of responsive treatment).

• 1. Interrole conflict occurs because expectations and behaviors from different roles held by a single individual clash. Your boss wants more hours just when you have finals. A critical meeting for my Sheltie Club occurs at the identical time I must move my mother down to Florida. You and your friends celebrating a work achievement emerge from a bar at a popular local restaurant slightly tipsy--only to encounter your pastor coming with his family to dinner. This may involve a coordination of time and effort problems, or incompatible behaviors associated with each role--or both.

We may segregate or compartmentalize roles (e.g., keep work away from your family; be an ogre at work, a loving parent at home--or vice-versa).

We may use role specialization (e.g., Daddy disciplines, Mommy hugs and kisses).

We may negotiate role performance (I'll work more now for time off then).

We prioritize roles (Mom is more important than Sheltie Club--sorry, Franki and Voncie).

• 2. Intrarole conflict describes conflicting expectations about the same role. This can occur in two main ways.

Second, the role itself may have conflicting expectations built-in to it.These conflicting expectations can even be held by the same person, including the role incumbant. Perfect dads are supportive and sensitive yet also must discipline their children. The good employee is loyal to boss and co-workers, yet is expected to become a "whistle blower" should illegal or unethical events occur.

Again, to cope with intrarole conflict, we may segregate or compartmentalize roles by breaking down a single role (e.g., professor) into subcomponents (teacher, researcher). We may avoid people whom we believe define a role in ways detrimental to us (avoid the "party animal" the semester we are studying for comps). Alternatively, we can keep people who hold incompatible expectations about the same role apart (don't invite your grandmother to the fraternity party).

Perhaps the most difficult task is to create role integration, by redefining or reconstructing the meaning and duties of a role so that it no longer seems internally contradictory. For example, I may decide that "being a good mother" means paying more individualized attention to my son and laughing at his jokes, rather than preparing gourmet meals or ironing his shirts (ironing? what's that?)

Roles are major contributions to our sense of self. Role stability promotes a stable sense of self. Discarding roles or role loss often can create a sense of personal upheaval. Within reason, a variety of roles and competent role performances make us happy. Roles--can often keep us sane!
 

One of the most important distinctions is social psychology is the difference between conformity and compliance.

• Group conformity is typically internally motivated, such as normative or informational influence.

• Compliance is externally driven.

It is very costly for a society to use compliance to achieve the desired behaviors from its members instead of conformity. Compliance often means a large, expensive, internal army or police force, and constant rewards or punishments must be dangled in front of members to make them behave. If a society can get its members to accept influence because they want to, then it will have resources to use for many other purposes, not just "enforcement." The difficulty, of course, is that many things that are required just aren't fun. One possibility is to hold out the promise of individual or collective reward (e.g., family honor). Another is to stress  legitimate authority, wherein individuals conform because they ought to(rather than "want to" or "must").

EVERYBODY conforms at times, no matter how "individualistic" we may think we are: try driving without it! Cultures and subcultures vary in terms of how much conformity they expect from their members and how much they expect members to lives in groups rather than apart. These expectations may be age- or gender-graded.

Group "deviants" often receive much initial pressure to conform. However, if individuals stay deviant after persuasion attempts, other members will isolate them. Deviants may also be expelled if group rules and norms allow this. Groups can create conformity norms (the autokinetic effect).

Informational influence occurs through comparative reference groups who provide social standards. Similarity among group members is important here and issues of self-identity with the group are also important.
 This relates to the social comparison processes I discussed in earlier class sessions.

Conformity effects increase with a large proportional majority, an unfamiliar task (the Asch experiment), spontaneous or confrontational situations, cross-pressures, high cohesiveness and a commitment to future interaction. However, remember: just one dissident is often all it takes to reduce conformity (remember the Obedience film or the Asch line experiment). And, a minority can influence the group and introduce innovation, especially if the minority has something special to offer or bargain with or minority members are able to create coalitions.
 

Group cohesion, or a sense or spirit of group unity collectively held by the membership, is one of the most important constructs in group dynamics. Although we know better, and we have known better for over 50 years, there is a tendency to see the effects of group cohesion as largely positive. It is not clear why such a positive bias occurs. Perhaps our personal experiences in cohesive groups blur our professional judgement. Perhaps when positive effects occur, they are so positive that we overlook the negative effects of cohesiveness.

There is no denying that experiencing group cohesion has many beneficial consquences for members and for the group as a whole.

On the average, members are more satisfied in cohesive groups.

Members remain in cohesive groups longer when a choice is available.

Cohesive groups appear to provide a buffer against stress and thus may positively contribute to individual mental and physical health.

Members of cohesive groups less often report feeling lonely or isolated.

Identity with the group is stronger in more cohesive groups.

Some cohesive groups are more productive.

With a lineup like this, what can there possibly be to criticize?
 

Despite the positive blinkers, negative effects of cohesion are plentiful. Not only that, when the negative effects of group cohesiveness occur, they tend to be spectacularly bad. Almost certainly the identical dynamics that produce "good" outcomes in groups also produce the "bad" outcomes in groups. The major culprit is the desire among group members to remain in the group and to please other group members. This is what gives groups an enhanced ability to influence members. A secondary villain is a structure that discourages--or at least that fails to actively encourage--interaction between the group and its outside environment.

In terms of process, here's what's going on:

Highly cohesive groups can enforce group norms--whatever they are--much more effectively than less cohesive groups. Pressures to conform (internal pressures) are greater in cohesive groups, that's one reason why the difference between conformity and compliance can be so important. Because people value their membership in cohesive groups, they are willing to adjust their behavior to group standards. Even if there is initial "storming" and conflict, if the group "gels," a "norming" period follows and members conform.

However, compliance pressures are greater too. Cohesive groups put more pressure on deviants to accept group norms than less cohesive groups do. As a result, cohesive groups tend toward high surface--sometimes superficial--harmony. To avoid confrontation and other forms of ill-will members will publicly agree even when they privately disagree. Even if a brave member speaks up in opposition, cohesive groups can be very cruel toward "deviants." If they remain in the group, deviants tend to become isolates and possibly even scapegoats. When group members are aware of these sanctions, they engage in self-censorship either avoiding contentious topics or carefully monitoring their verbal responses.

Surface harmony combined with perceived group enemies can contribute to group insularity or insulation, the tendency of group members to interact primarily with each other and to avoid cross-group contacts. Once an imposed group homogeneity emerges, the group has closed itself off from cross-fertilization of ideas or from corrective input for its mistakes. Further, since members largely interact with one another, they may begin to feel invulnerable and superior to those who are not group members. There aren't any discrepant voices at that point to provide a different opinion.

Given such self-protective strategies, members can propose extreme ideas and face neither challenges nor corrections from other group members or from outsiders. Problems may be ignored or glossed over. The group is now on a one-way trip to bad decision-making. Group failures become interpreted as enmity from the outside environment and the cycle continues.

Sound familiar? How many current examples can you envision, from poor football plays to terrorist planning? Most of Jim Jones' commune in Guyana (although apparently not all) willingly drank poisoned fruit punch. The Webmasters at California's "Heaven's Gate" apparently believed that space ships would arrive for them after they, too, drank poison. Suicide bombers throughout the Middle East are told a spot in Paradise is reserved for them.

But we don't have to think of such dramatic instances. Teenagers often make poor decisions to be accepted by their peers and reject criticism of their actions. Spouses set aside their own notions of right and wrong to please someone they love, even if it sometimes means illegal actions.
 

Irving Janis coined the term "Groupthink" to decribe this process and cycle of "bad decision-making." Bad decisions occur because group members are only exposed to limited and asymmetric information, typically information that supports the group's decisions. Opposition from within is effectively stifled. Opposition from without is never even referenced. Disaster occurs, leaving group members to shake their heads, wondering what went wrong.

The first sign that something has gone wrong (aside from dramatic disasters such as the Challenger explosion or finding the suicidal bodies) may be that cohesion breaks down and members begin to leave the group without signifying their intentions or even giving an explanation. Members may leave because they privately disagree but believe that they cannot voice their dissent aloud. Or, members may agree with group goals overall, but disagree with the stifling of diverse opinions.

Group productivity may drop precipitously and outside authorities are called in (e.g., principals or higher level bosses), while the remaining members refuse to even acknowledge that there are any problems at all. One of the congregations I studied was affiliated with a major African-American, highly centralized denomination. By the time the observer was in the field, that church was down to 35 people, most of them relatives of the elderly pastor. The Sunday School was so small that all grades were held in one room. The pastor and members refused to acknowledge that any problems even existed and the pastor stubbornly rejected any invitations to participate in events with other churches. Ultimately, the pastor was retired by the denomination, which sent down a young, energetic pastor to revitalize the church.

Some other consequences of high cohesion that many would call negative include:

• Scapegoating, hostility and aggression are more common toward deviants in more cohesive groups.

• Individual identity may be more restricted in cohesive groups. Because members are typically closer to one another, they may feel "an investment" in how you look, dress, or talk. If you try to change aspects of your personal identity--even in a positive direction, such as becoming more physically fit--you may find to your surprise that other group members ignore, criticize or otherwise undermine your attempts at improvement. Sit on Landis Green some fine day and see how much diversity in student dress you do (or do not) observe.

• If group goals diverge from organizational goals, not only may the group as a whole become less productive (by organizational standards), it may also reject members who are productive by organizational standards (e.g., ostracizing the "class brain" or "binging" workers viewed as "overproductive.")

What was the conflict? Highly cohesive groups who valued social interaction spent their time on that, not on the group task imposed by the experimenter. Everyone got along great, everyone liked everyone else. Group task productivity was terrible.
