集団のステレオタイプは,個人が逸脱すると変化します. ある研究によると 偏ったメンバーは別々に見られ メンバーに対する集団の認識や信念が変わります
科学分野:
- 社会心理学
- 認知科学
- コンピュータ社会科学
背景:
- 集団のステレオタイプは頑固で 差別を助長します
- 集団の表現がどのように信念を形成し 影響するかを理解することは極めて重要です
研究 の 目的:
- グループ認識とステレオタイプ形成に関する構造学習モデルの予測をテストする.
- 集団内の偏差が 集団の表現と関連した信念に どう影響するか調べる
主な方法:
- グループ偏差に対する人間の反応を調査するために 7つの実験が行われました
- グループ構造に対する参加者の認識と信念に対する信頼が測定された.
- エージェントの類似性に基づくステレオタイプ精度の新しい測定法が開発され,分析されました.
主要な成果:
- 偏差の増加は,偏差のエージェントの"サブグループ化"と最終的な"サブタイプ化"につながった.
- 集団の信念に対する自信は,まず偏差とともに減少したが,サブタイプ化後に増加した.
- 探査分析により,ステレオタイプの精度は,知覚されたエージェントの類似性と相関していることが明らかになった.
結論:
- グループ表現はダイナミックで,メンバーの偏差によって影響を受けます.
- 偏差は新しいサブグループの形成や個人の排除につながる可能性があります.
- ステレオタイプの精度は,グループメンバーの認識された同質性に関連しています.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974).

Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Deindividuation
27.2K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
