Affiliation and Social Comparison
The extent to which individuals use social comparison to determine their evaluations of events was demonstrated in a set of classic research studies conducted by Stanley Schachter (1959). Schachter’s experiments tested the hypothesis that people who were feeling anxious would prefer to affiliate with others rather than be alone because having others around would reduce their anxiety. Female college students at the University of Minnesota volunteered to participate in one of his experiments for extra credit in their introductory psychology class. They arrived at the experimental room to find a scientist dressed in a white lab coat, standing in front of a large array of electrical machinery. The scientist introduced himself as Dr. Zilstein of the Department of Neurology and Psychiatry, and he told the women that they would be serving as participants in an experiment concerning the effects of electrical shock. Dr. Zilstein stressed how important it was to learn about the effects of shocks, since electroshock therapy was being used more and more commonly and because the number of accidents due to electricity was also increasing!
At this point, the experimental manipulation occurred. One half of the participants (those in the high-anxiety condition) were told that the shocks would be “painful” and “intense,” although they were assured that they could do no permanent damage. The other half of the participants (those in the low-anxiety condition) were also told that they would be receiving shocks but that they would in no way be painful—rather, the shocks were said to be mild and to resemble a “tickle” or a “tingle.” Of course, the respondents were randomly assigned to conditions to assure that the women in the two conditions were, on average, equivalent except for the experimental manipulation.
Each of the women was then told that before the experiment could continue, the experimenter would have to prepare the equipment and that they would have to wait for a while until he was finished. He asked them if they would prefer to wait alone or to wait with others. The outcome of Schachter’s research was clear—while only 33% of the women who were expecting mild shocks preferred to wait with others, 63% of the women expecting to get painful shocks wanted to wait with others. This was a statistically significant difference, and Schachter concluded that the women chose to affiliate with each other in order to reduce their anxiety about the upcoming shocks.

In further studies, Schachter found that the research participants who were under stress did not want to wait with just any other people. They preferred to wait with other people who were expecting to undergo the same severe shocks that they were rather than with people who were supposedly just waiting to see their professor. Schachter concluded that this was not just because being around other people might reduce our anxiety but because we also use others who are in the same situation as we are to help us determine how to feel about things. As Schachter (1959) put it, “Misery doesn’t just love any kind of company, it loves only miserable company” (p. 24). In this case, the participants were expecting to determine from the other participants how afraid they should be of the upcoming shocks.
In short, and as predicted by the idea of social comparison, the women in Schachter’s studies relied on each other to help them understand what was happening to them and to find out how they should feel and respond to their social situations. Again, the power of the social situation—in this case, in determining our beliefs and attitudes—is apparent.
Although Schachter’s studies were conducted in relatively artificial lab settings, similar effects have been found in field studies in more naturally occurring settings. For instance, Kulik, Mahler, and Moore (1996) found that hospital patients who were awaiting surgery preferred to talk to other individuals who were expecting to have similar procedures rather than to patients who were having different procedures, so that they could share information about what they might expect to experience. Furthermore, Kulik and his colleagues found that sharing information was helpful—people who were able to share more information had shorter hospital stays.
Upward and Downward Comparisons Influence Our Self-Esteem
Although we use social comparison in part to develop our self-concept—that is, to form accurate conclusions about our attitudes, abilities, and opinions—social comparison has perhaps an even bigger impact on our self-esteem. When we are able to compare ourselves favorably with others, we feel good about ourselves, but when the outcome of comparison suggests that others are better or better off than we are, then our self-esteem is likely to suffer. This is why good students who attend high schools in which the other students are only average may suddenly find their self-esteem threatened when they move on to more selective colleges in which they are no longer better than the other students (Marsh, Kong, & Hau, 2000). I’m sure you’ve had the experience yourself of the changes in self-esteem that occur when you have moved into a new grade in school, got a new job, or changed your circle of friends. In these cases, you may have felt much better about yourself or much worse, depending on the nature of the change. You can see that in these cases the actual characteristics of the individual person has not changed at all; only the social situation and the comparison others have changed. And yet the social situation can make a big difference in one’s self-esteem.
Because we naturally want to have positive self-esteem, we frequently attempt to compare ourselves positively with others. Downward social comparison occurs when we attempt to create a positive image of ourselves through favorable comparisons with others who are worse off than we are. Morse and Gergen (1970) had students apply for a job, and they also presented the students with another individual who was supposedly applying for the same job. When the other candidate was made to appear to be less qualified for the job than they were, the downward comparison with the less qualified applicant made the students feel better about their own qualifications. As a result, the students reported higher self-esteem than they did when the other applicant was seen as a highly competent job candidate. Research has also found that people who are suffering from serious diseases prefer to compare their condition with other individuals whose current condition and likely prognosis is worse than their own (Buunk, Gibbons, & Visser, 2002). These comparisons make them feel better about their own possible outcomes.
Although downward comparison provides us with positive feelings, upward social comparison, which occurs when we compare ourselves with others who are better off than we are, is also possible (Blanton, Buunk, Gibbons, & Kuyper, 1999; Vrugt & Koenis, 2002). Although upward comparison may lower our self-esteem by reminding us that we are not as well off as others, it is useful because it can provide information that can help us do better, help us imagine ourselves as part of the group of successful people that we want to be like (Collins, 2000), and give us hope (Snyder, Cheavens, & Sympson, 1997).
The outcomes of upward and downward social comparisons can have a substantial impact on our feelings, on our attempts to do better, and even on whether or not we want to continue performing an activity. When we compare positively with others and we feel that we are meeting our goals and living up to the expectations set by ourselves and others, we feel good about ourselves, enjoy the activity, and work harder at it. When we compare negatively with others, however, we are more likely to feel poorly about ourselves and enjoy the activity less, and we may even stop performing it entirely. When social comparisons come up poorly for us, we experience depression or anxiety, and these discrepancies are important determinants of our self-esteem (Higgins, Loeb, & Moretti, 1995; Strauman & Higgins, 1988).
Social Groups Provide Social Identity
Still another way that we use other people to create positive self-esteem is through our group memberships. We use the social situation to gain self-esteem by perceiving ourselves as members of important and valued groups that make us feel good about ourselves. Social identity refers to the positive emotions that we experience as a member of an important social group (Hogg, 2003; Oakes, Haslam, & Turner, 1994; Tajfel, 1981).
Normally, our group memberships result in positive feelings, which occur because we perceive our own groups and thus ourselves in a positive light. If you are a “Midwesterner at heart,” or if you live in the “best fraternity house on campus,” your membership in the group becomes part of what you are, and the membership makes you feel good about yourself. The list that follows presents a measure of the strength of social identity with a group of university students, which might give you a good idea of the variable. If you complete the measure for your own university or college, I would imagine that you would agree mostly with the statements that indicate that you do identify with the group.
