The present study aimed to examine the antecedent conditions of pluralistic ignorance and its consequences, especially on individuals’ micro processes. Japanese college students participated in a laboratory experiment and met their partners in another room, these actually being confederates. They were asked to do some choice tasks regarding their preferences of gummy candy flavors. Next, they were led to believe that their partners made choices identical to theirs, and estimated the partners’ preferences. They were then asked to choose one flavor as a reward for themselves and their partners, and to evaluate their preferences again. The result suggested a process of the occurrence and consequences of pluralistic ignorance as follows: (1) People tend to see the choices made by others as reflections of their preferences, even when their own identical choices are made to eliminate dislikable alternatives. (2) They tend to take action as group members to meet others’ preferences, even when those are different from their own preferences. (3) When confronted with the inconsistency between their actions and preferences, people are motivated to justify their actions by changing their preferences.

本研究の目的は,多元的無知の先行因を検討することである。具体的には,「集団メンバーの行動を観察したとき,その行動が彼ら自身の選好と反していると推測する者ほど,却って当該行動の『規範性』を認知し,それに沿って振る舞う」という仮説を検討した。研究1では大学生の時間厳守規範に焦点を当てて通時的調査を行い,仮説に合致する現象を確認した。研究2では,実験室実験によって当該現象の生起プロセスをより精緻に検証した。参加者は5人1組で実験室に入り,2種類の水を試飲して品質の評定を行うという課題をひとりずつ順番に行った。このとき,すべての参加者が,自分は4番目に配置されていると信じており,先行する3人が「不味い」水を「より高品質である」として選択する様子を観察した。結果,「先行の参加者は(前の人に合わせて)個人的選好と反する行動をしている」と推測する者ほど,当該の行動の規範性を知覚しており,それゆえに自らも規範に沿って振る舞う(「不味い」水を選択する)ことが示された。

This study investigated factors leading to normative behavior, focusing on residential mobility and reputation estimation. As people in societies with high levels of residential mobility have many chances to build new relationships, it is important for them to establish positive reputations and extend their human resources. However, the incentive to develop a positive reputation may vary depending on the needs and abilities of those engaged in relationship-building. We hypothesized that in societies with high levels of residential mobility, only those who need to build and are capable of building new relationships would follow social norms, when they think it will help to earn a positive reputation from others. On the other hand, people in societies with low levels of residential mobility have few opportunities to build new relationships and thus they may try to avoid negative reputations in order to maintain their current relationships. We hypothesized that in societies with low levels of residential mobility, people would overestimate the possibility of acquiring negative reputations when they deviate from social norms, and they would therefore follow the norms to avoid ending up with negative reputations. The hypotheses were supported by our online survey, in which we focused on normative aspects of participation in community activities.

In this article, we discuss two types of intervention for making judgments and decisions more rationally; nudge and boost. In particular, we discuss characteristics, theoretical background, and problems in the nudge and boost. We argue the importance of multiple perspectives, such as individual, group, and psychological conflict, for making judgments and decisions more rationally.

This study investigated how social norms are maintained in societies with different degrees of relational mobility. We hypothesized that (1) in high relational mobility societies, where they need to present their attractiveness to be chosen as a relational partner, people would follow social norms when they thought it would earn them a positive reputation from others; (2) in low relational mobility societies, where they need to avoid isolation in closed relationships, people would follow social norms when they thought they would be rejected by others if they did not. We also examined to what extent their reputation estimation was accurate. In particular, normative aspects of participation in community activities were investigated using a social survey. As we predicted, the more the respondents in low relational mobility societies feared rejection by others, the more they followed norms regarding participation in community activities. They tended to assume that others would give a lower evaluation to a nonparticipant than they do, which means that they may maintain the norms as a result of “pluralistic ignorance.” On the other hand, we did not find a significant interaction effect between perceived relational mobility and expectation of a positive reputation. This was explained by the respondents’ tendency to underestimate the possibility of earning a positive reputation by participating in community activities.
