まとめ
複製研究によると 銀行家の不誠実さは 仕事を考慮すると 一貫して高くないことが分かりました これは以前の調査結果に 異議を唱えるものです 文化と選択のバイアスは,オリジナルの銀行家行動研究の一般化を制限する可能性があります.
科学分野:
- 社会科学
- 行動経済学
- 組織的行動
背景:
- 社会科学は再現性の危機に直面し 影響力のある発見はしばしば複製に失敗します
- 銀行家のようなアクセス不可能な集団を対象とした研究の複製は 十分に検討されていません
- 以前の研究によると 銀行員は 職に就く際の不正行為が 多いとされています
研究 の 目的:
- 銀行家の不正行為に関する調査結果の 汎用性を検証するためです
- 銀行員に自分の仕事について考えさせることで 不誠実な行動が増加するかどうかを調査する.
- 銀行文化に関する研究の再現性に影響を与える要因を探求する.
主な方法:
- 銀行家の不誠実さに関する以前の研究を再現した.
- 3つの大陸の5つの集団で 銀行家や非銀行家を含む1,282人の参加者を集めました
- 職について考える準備ができている銀行家と そうでない銀行家の 誠実さのレベルを比較しました
主要な成果:
- 中東とアジア太平洋の銀行家たちの間では 不誠実さが見られていましたが,仕事に関連したプライミングによって著しく増加することはありませんでした.
- 銀行以外の専門職に 仕事の内容を教えても 誠実さには大きな影響はありませんでした
- 各国の銀行業者の行動に対する公衆の期待の変動と,参加機関における潜在的な選択バイアスを特定した.
結論:
- 銀行家の不正行為の増加に関する 初期の調査結果は 世界的に一般化できないかもしれません
- 文化的差異と制度的な選択バイアスは 繊細なフィールドワークの再現性と有効性に影響を及ぼします
- 政策立案者は,銀行文化に関する研究の結果を一般化する際には注意を払うべきです.

15.3K
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...

02:13The Representativeness Heuristic
16.6K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

7.2K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

01:31Confirmation Biases
7.6K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
