The existence of the false consensus is determined when the consensus estimates for an option provided by people who personally endorsed it surpass the same estimate provided by people who did not choose the option. Furthermore, the difference between these two estimates can be conceptualized as the magnitude of the FCE, and this was compared between the two cultures.
Unlike the original study, we also conducted an accuracy analysis by subtracting the actual consensus in the sample in order to see which process was responsible for the patterns of FCE.
A total of 57 American undergraduates identifying themselves as European Americans and 53 Korean undergraduates at a large university in the respective country participated in this study as a partial fulfillment of course requirements.
The data of the participants who did not complete the questionnaire were excluded from the following analyses. Responses from 52 European Americans and 49 Koreans were subject to final analyses. Materials and general procedures were adopted from Study 1 of Ross et al.
Participants were given brief descriptions of hypothetical conflict situations that eventually asked for a behavioral choice between two options. From the original set of situations, two stories were selected: The Term Paper story and the Supermarket story.
These stories were selected because they contained situations and decisions that ordinary college students may encounter in both the cultures.
In the Term Paper story, students faced a situation where they have to decide to write a final paper individually or as a team for a course. The whole story read as follows:.
You arrive for the first day of class in a course in your major area of study. The professor says that the grade in your course will depend on a paper due the final day of the course. He gives the class the option of two alternatives upon which they must vote.
They can either do papers individually in the normal way or they can work in teams of three persons who will submit a single paper between them. In the Supermarket story, students were given a situation where people from a supermarket chain unwittingly filmed their comments about the supermarket and were asking participants to sign a release to use the film for a TV commercial.
The story continued as follows:. As you are leaving your neighborhood supermarket, a man in a business suit asks you whether you like shopping in that store. You reply quite honestly that you do like shopping there and indicate that in addition to being close to your home, the supermarket seems to have very good meat and produce at reasonably low prices.
The man then reveals that a videotape crew has filmed your comments and asks you to sign a release allowing them to use the unedited film for a TV commercial that the supermarket chain is preparing. After reading each story, participants estimated the proportion of peers who would agree to choose each option Paper: group vs.
The materials were translated and back-translated into Korean for the Korean participants. On arrival at the laboratory, participants were presented with a packet containing the descriptions of two hypothetical situations. After reading each story, they were asked to estimate the percentages of their peers who would choose option 1 or 2.
Participants were also asked to indicate which behavioral alternative they would choose personally. After completing the questionnaire, participants were fully debriefed and dismissed. The data were analyzed in two ways. First, we adopted Ross et al. This allows us to confirm the existence of the FCE in Koreans and European Americans and to explore whether there is any cultural difference in the magnitude of the effect between the two cultures.
According to Ross et al. Thus, consensus estimates for option 1 voting for group paper; signing the release provided by people who personally chose options 1 and 2 were compared through independent sample t tests. The analysis of the perceived consensus in each culture shows that FCE is quite prevalent see Table 2.
Table 2. Perceived consensus within each culture: estimated percentage of people who would choose option 1 provided by the raters who chose either option 1 or option 2.
This suggests that Koreans made lower estimations for the percentage of people who would prefer option 1 than Americans. For example, in the Supermarket story, Koreans who personally preferred to sign the release option 1 estimated that The difference in the estimates of Koreans for option 1 was However, in the same story, European Americans who chose to sign the release option 1 estimated that the percentage of people who would choose the same to be Thus, the difference in the estimates of European Americans for option 1 was only 8.
The similar pattern applied to the Term Paper story as well. Because the difference in consensus estimates can serve as an indicator for the size of the FCE, this pattern suggests that Koreans show larger FCE than European Americans see Figure 1. Figure 1. In sum, the FCE was observed to be a robust phenomenon in this traditional paradigm using hypothetical situations. People from both cultures demonstrated the FCE. However, the comparison revealed some cultural variations as well: Koreans seemed to exhibit greater FCE than European Americans.
Although the previous analysis revealed the existence of the cultural variation, it does not allow us to understand what had happened in the estimation. Especially, some researchers even have suggested that East Asians might be more keen to consensus information and might show less false consensus; thus, the additional accuracy analyses might shed some light on this perspective.
In order to analyze the accuracy of estimation, we first calculated the difference scores between the estimated consensus and actual consensus. We subtracted the actual percentage of peers who chose option 1 in each sample see Table 2 from the estimated consensus provided for option 1. The accuracy of estimation can be examined in two ways: First, analysis on the absolute value of the difference scores can determine whether the estimation was deviant from the actual consensus or not; second, analysis on the raw difference score can provide information regarding the direction of the deviation, i.
Results from these two analyses were presented in order. First, we used the absolute value of the difference in order to see whether accurate estimation of Koreans or Americans has contributed to the cultural pattern. Scores close to zero indicate accurate judgments, and any deviation from zero indicates an inaccurate estimation.
Option 2 ANOVA on the absolute score revealed slightly different results depending on the type of story. The results show that neither Koreans nor Americans were, in general, more accurate than the other, as some researchers have suggested. Rather, their accuracy depended on the type of story. Furthermore, even in the case where Koreans were found to be more accurate than Americans, their accuracy did not lead them to show less FCE.
Therefore, the hypothesis stating that Koreans should show less FCE than Americans because they have more accurate knowledge of others does not seem to hold in our study. The accuracy of estimation in an absolute sense does not provide a meaningful explanation for the cultural pattern we found. The next analysis involved the raw difference scores. Scores close to zero indicate accurate judgments, and any deviation from zero indicates an inaccurate estimation with directions: Positive scores indicate overestimation, whereas negative scores indicate underestimation.
The mean difference scores in each condition and the results of the significance tests comparing the difference scores against a value of zero are presented in Table 3. Table 3. Accuracy of estimation: Actual percentage of peers who chose option 1 subtracted from the estimated percentage of people who would choose option 1 with significance tests against zero. Figure 2. In sum, this study revealed the existence of a cultural difference in the FCE: Koreans were found to show a greater FCE than Americans in a task involving personal opinion in hypothetical situations.
It seems that overestimating the consensus for the choice they made was not enough for Koreans; they may have needed to go even further to underestimate the consensus for the other option in order to feel that they are safe in the ordinary.
Still, some might raise the possibility that the scenarios and behavioral choices we examined in this study were culture-bound. For example, in the Term Paper story, East Asians are likely to prefer group papers, whereas Westerners prefer individual papers; and this difference in the prevalence of choice for each story might complicate the cultural comparison, and even more, be the source of the cultural pattern of the FCE.
However, the response rate for the Supermarket story shows exactly the opposite cultural pattern: a majority Still, the cultural pattern of the FCE perceived consensus, Figure 1 was parallel across the two stories.
In addition, the additional accuracy analysis with difference scores, which adjusts the estimated consensus with the actual consensus from each culture, shows that the pattern of accuracy Figure 2 is also parallel across the two stories. This suggests that the cultural difference in the FCE goes beyond the specific cultural preferences e. One of the contributions of this study lies in that our analysis on the accuracy of the FCE provided a unique opportunity to examine two competing hypotheses regarding the direction of the potential cultural difference.
As reviewed earlier, a substantial body of cultural literature acknowledges the fact that people from East Asian culture, characterized by collectivism, an interdependent self and a social goal of harmony, are more sensitive to consensus information and norm and perceive themselves as similar to others than their Western counterpart.
Our results from the accuracy analysis indicated that there is no evidence that Koreans are more accurate than European Americans in estimating the consensus of opinions in general. Furthermore, their accuracy in an absolute sense did not seem to contribute to the cultural pattern we found for the FCE. Koreans did seem to have better knowledge of others and show some level of accuracy in certain contexts e.
This research examined the potential cultural variations of the FCE and attempted to fill the gap in the literature. By examining the cultural effects in the original settings that were used in the initial study on FCE by Ross et al.
The two studies comparing the FCE between two cultures demonstrated both universal and cultural specificity: This research confirmed the general existence of the tendency that people overestimate the prevalence of their own choices across cultures; however, a more important contribution comes from the fact that this study revealed some noticeable cultural variations that had been anticipated. First, the examination of the choice domains revealed some cross-cultural pattern.
Findings from Study 1 demonstrated that cultural variation existed in the type of items that was more susceptible to the effect. This finding supports the notion on the difference of self-clarity i. Furthermore, the author also noted one of the reasons that might lead to the greater FCE in these items for Koreans lies in the fact that the attribute items used in the study pertain to social relationship maintenance features, indicative of concern for others, and group harmony, which does not apply to our study.
It might be possible that item categories demonstrating certain patterns of the FCE point to the location of motivational or cognitive importance of each culture. This possibility awaits further scrutiny. Furthermore, we were able to find cultural differences in the FCE in terms of the relative size of the effect. Overall, Koreans seem to show stronger FCE than European Americans, especially regarding personal choices involving political expectations and personal problems Study 1 and behavioral choices in hypothetical situations Study 2.
This result seems to be consistent with what previous literature on cultural studies has suggested in the light of the traditional accounts of the FCE. Two major accounts that provide explanations for the FCE are selective exposure and causal focus. Selective exposure or availability account of the FCE focuses on the fact that people tend to know and associate with others with whom they share their background, experiences, and interests; furthermore, it maintains that this selective exposure to this similar others and the availability of information about them breeds a false consensus Sherman et al.
In a collectivistic and interdependent culture, such as in East Asian culture that values group identities and the goal of social harmony e. These observations bolster the notion that East Asians are selectively exposed to similar others more than Westerners, which can explain the stronger FCE among Koreans than among European Americans, whose culture value is unique. Causal focus account of the FCE, suggested by Gilovich et al.
For example, if causal analysis focuses on situational aspects, individuals will infer that the powerful situational influence should govern the behavior of others as well as their own, and the false consensus should be strengthened.
Well-documented findings now confirm that people in Eastern cultures tend to accept the power of situational influence more than their Western counterpart and thus be less susceptible to the fundamental attribution error e. In this sense, it is not surprising to find that East Asians extend the commonness of their own choices to a greater degree than Westerners. In addition, our findings negated the alternative prediction that East Asians might succumb less to the FCE based on the fact that they tend to have better knowledge of others than European Americans.
However, it is possible that East Asians have relatively more accurate knowledge of others than their Western counterparts; however, results from our studies suggested that this particular cognitive advantage did not completely override other biases that might be responsible for the FCE in East Asians.
Our analysis on the accuracy of estimation in Study 2 seems to offer partial support for this point. Koreans who chose the group paper Option 1 in the Term Paper story seemed to estimate the consensus pretty accurately. However, Koreans who chose the individual paper Option 2 underestimated the percentage of people who endorsed the other option, which led to greater FCE than European Americans.
It strongly suggests that there is something more than better knowledge of others or need for accuracy that drives the specific pattern in Koreans. Our analysis on accuracy with difference scores between the estimated and actual consensus revealed that stronger FCE on the part of South Koreans is in part due to their tendency to overestimate the prevalence of people who chose the same option to their own and to underestimate the prevalence of people who chose an option other than their own.
Unlike independent North Americans who emphasize the value of uniqueness, interdependent East Asians are known to value modesty and harmony Markus and Kitayama, In addition, it is suggested that East Asians may have a strong motivation to see oneself as normal and ordinary and hold a belief that being ordinary is safe and also beneficial e. In sum, this research examined the potential cultural variations of the FCE and attempted to fill the gap in the literature.
It was found that generally, East Asians tended to overestimate the prevalence of their choices to a greater degree than Westerners, and this cultural pattern varied depending on the domains of choices.
Previous literature allowed us to speculate on the possible reasons for the observed cultural variations, and these accounts seem to provide plausible explanations for the cultural patterns.
The way we perceive others and how we attribute their actions hinges on a variety of variables, but it can be heavily influenced by whether we are the actor or the observer in a situation. When it comes to our own actions, we are often far too likely to attribute things to external influences.
For example:. While there are many factors that may play a role, perspective plays a key role. When we are the actors in a situation, we are able to observe our own thoughts and behaviors. When it comes to other people, however, we cannot see what they are thinking. This means we focus on situational forces for ourselves, but guess at the internal characteristics that cause other people's actions.
The problem with this is that it often leads to misunderstandings. Each side of a situation is essentially blaming the other side rather than thinking about all of the variables that might be playing a role.
The false consensus effect is the tendency people have to overestimate how much other people agree with their own beliefs, behaviors, attitudes, and values.
Researchers believe that the false consensus effect happens for a variety of reasons. First, the people we spend the most time with, our family and friends, do often tend to share very similar opinions and beliefs. Because of this, we start to think that this way of thinking is the majority opinion even when we are with people who are not among our group of family and friends. Another key reason this cognitive bias trips us up so easily is that believing that other people are just like us is good for our self-esteem.
It allows us to feel "normal" and maintain a positive view of ourselves in relation to other people. This can lead people not only to incorrectly think that everyone else agrees with them—it can sometimes lead them to overvalue their own opinions. It also means that we sometimes don't consider how other people might feel when making choices. The halo effect is the tendency for an initial impression of a person to influence what we think of them overall.
Also known as the " physical attractiveness stereotype " or the "what is beautiful is 'good' principle" we are either influenced by or use the halo to influence others almost every day. One factor that may influence the halo effect is our tendency to want to be correct.
If our initial impression of someone was positive, we want to look for proof that our assessment was accurate. It also helps people avoid experiencing cognitive dissonance , which involves holding contradictory beliefs.
This cognitive bias can have a powerful impact in the real world. For example, job applicants perceived as attractive and likable are also more likely to be viewed as competent, smart, and qualified for the job. The self-serving bias is a tendency for people tend to give themselves credit for successes but lay the blame for failures on outside causes.
But when things turn out badly, you are more likely to blame it on circumstances or bad luck. The self-serving bias can be influenced by a variety of factors. Age and sex have been shown to play a part. Older people are more likely to take credit for their successes, while men are more likely to pin their failures on outside forces. This bias does serve an important role in protecting self-esteem. However, it can often also lead to faulty attributions such as blaming others for our own shortcomings.
The availability heuristic is the tendency to estimate the probability of something happening based on how many examples readily come to mind. Some examples of this:. It is essentially a mental shortcut designed to save us time when we are trying to determine risk. The problem with relying on this way of thinking is that it often leads to poor estimates and bad decisions. Smokers who have never known someone to die of a smoking-related illness, for example, might underestimate the health risks of smoking.
In contrast, if you have two sisters and five neighbors who have had breast cancer, you might believe it is even more common than statistics suggest. The optimism bias is a tendency to overestimate the likelihood that good things will happen to us while underestimating the probability that negative events will impact our lives.
Essentially, we tend to be too optimistic for our own good. For example, we may assume that negative events won't affect us such as:. The optimism bias has roots in the availability heuristic. Because you can probably think of examples of bad things happening to other people it seems more likely that others will be affected by negative events. This bias can lead people to take health risks like smoking, eating poorly, or not wearing a seat belt.
The bad news is that research has found that this optimism bias is incredibly difficult to reduce. There is good news, however. This tendency toward optimism helps create a sense of anticipation for the future, giving people the hope and motivation they need to pursue their goals.
The cognitive biases above are common, but this is only a sampling of the many biases that can affect your thinking. These biases collectively influence much of our thoughts and ultimately, decision making.
Many of these biases are inevitable. We simply don't have the time to evaluate every thought in every decision for the presence of any bias. Understanding these biases is very helpful in learning how they can lead us to poor decisions in life.
