Confirmation Biases01:31

Confirmation Biases

7.2K
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?

Stereotype Threat and Self-fulfilling Prophecies

38.7K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. 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...

Natural Selection and Mating Preferences01:06

Natural Selection and Mating Preferences

173
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing,...

Sign Test for Nominal Data01:12

Sign Test for Nominal Data

152
The sign test is a nonparametric method used to evaluate hypotheses about the median of a single sample or to compare the medians of two related samples. The sign test is particularly useful when dealing with nominal data, which includes distinct categories without an inherent order, such as names, labels, and preferences. Nominal data restricts statistical analysis to evaluating population proportions rather than mean or median values that require continuous data.
For example, consider a...

Mate Choice01:20

Mate Choice

10.4K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Persuasion Strategies01:52

Persuasion Strategies

39.6K
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

科学分野:

  • 医学教育
  • 外科 研修 室 の 入学
  • 申請者の審査

背景:

  • 優先シグナリングは2022年に一般外科の入院申請に導入されました.
  • 当初,申請者は5つの信号を使用することができ,2025年のマッチサイクルでは15に増加しました.
  • 2024年には,より広範な選考基準を示し,応募者を超えてプログラムがインタビューしました.

研究 の 目的:

  • 面接の選択に偏見信号のみを使用すると,応募者の人口統計に与える影響を評価する.
  • 3つのマッチサイクル (2023-2025) で異なるスクリーニング方法によって選択された申請者の特徴を比較する.
  • シグナルのみのスクリーニングへの移行が,申請者の群の多様性と質に影響を与えるかどうかを判断する.

主な方法:

  • 一つの学術医療センターの 整体外科研修プログラムでは 申請書を総合的に検討しました
  • 応募者のデータ (性別,人種,医学部地域,審査員スコア,ステップ2スコア) を分析した.
  • カテゴリ別変数と連続変数に対してキ二乗とtテストを使用し,ANOVAで3つのグループを比較した.

主要な成果:

  • 2023,2024年と2025年の間,全体的に審査された申請者において,有意な人口的差異は認められなかった.
  • 2024年には,教員選択とシグナル選択の申請者間で人口格差はありませんでした.
  • 偏好信号のみを使用した2025年サイクルでは,前年と比較できる申請者プールが生まれました.

結論:

  • 一般外科の入院希望者の検診は 偏好信号のみを用いて 効率的な方法です
  • このアプローチは,初期スクリーニングの作業量を大幅に削減します.
  • 偏好シグナルの利用は,インタビューされた申請者の群の多様性や品質に悪影響を及ぼしません.
