Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.3K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Principle of Equivalence

2.2K
According to Albert Einstein (1897-1955), free-falling and feeling weightless are intrinsically linked. If a person were in free-fall under gravity, for example, diving towards the Earth from an airplane, they would feel completely weightless. Similarly, a person descending in a lift may feel partially weightless. Broadly speaking, it is assumed that an object in a uniform gravitational field and an object undergoing constant acceleration in the absence of gravity are under the same...

Continuity Equation01:20

Continuity Equation

The total amount of current flowing per unit cross-sectional area is called the current density. Hence, the current passing through a cross-sectional area can be written as the surface integral of the current density.

Equivalent Capacitance01:19

Equivalent Capacitance

326
From the study of resistive circuits, it is understood that employing a series-parallel combination serves as an effective strategy for simplifying circuits. Capacitors can be arranged within a circuit in one of two ways: a series configuration or a parallel configuration. The way these capacitors are connected to a battery will influence both the potential drop across each individual capacitor and the size of the charge that each capacitor can store. This is determined by the specific type of...

Reaction Quotient02:35

Reaction Quotient

48.2K
The status of a reversible reaction is conveniently assessed by evaluating its reaction quotient (Q). For a reversible reaction described by m A + n B ⇌ x C + y D, the reaction quotient is derived directly from the stoichiometry of the balanced equation as

随机对照试验 (RCT) 对于因果推断本身并不"足够". 统计方法需要理解社会背景和经验数据,而不仅仅是直觉,特别是观测研究.

科学领域:

  • 统计 统计 统计 统计
  • 社会学 社会学 社会学
  • 因果推理因果推理

背景情况:

  • 阿罗诺夫和其他人. (2021) 认为随机对照试验 (RCT) 足以推断因果关系,而观察性研究的非参数方法则不足.
  • 在统计充分性中",足够"的概念被认为是与同行评审等制度过程相关的社会学主张,而不是纯粹的统计.
  • 现有的统计实践往往依赖于关于现实数据复杂性的直觉,特别是关于倾向得分函数.

研究的目的:

  • 批判性地评估随机对照试验 (RCT) 对于因果推断来说"足够"的说法.
  • 为更广泛的统计充分性概念辩论,包括对社会背景的经验知识.
  • 倡导在观测研究中对因果推理的复杂性进行超科学研究.

主要方法:

  • 在统计充分性中对"足够"的定义和含义进行批判性分析.
  • 检查影响统计实践的社会学和制度因素.
  • 应用批评推系统作为一个案例研究,突出基于直觉的方法的局限性.

主要成果:

  • 统计方法的充分性不仅取决于统计逻辑,还取决于它们与上下文知识的整合.
  • 完全理解"足够"需要知识超越倾向分数,包括各种空间和时间的社会特征.
  • 统计学批评的实际实用性在很大程度上取决于具体的应用上下文,例如推系统.

结论:

  • 统计学家应该超越直觉,进行实证的超科学,以了解观察数据中因果推理的复杂性.
  • 在统计学中依赖"免费午餐",通常仅限于科技公司的利应用,应该受到质疑.
  • 实践统计学家必须明确考虑"为什么?" 和"为了谁?" 问题,以适当地解决他们的方法的充分性.
