概括
当一个措施成为一个目标时,它就不再有效了. 这种"代理失败"发生在专注于代理指标降低了实际目标时,在经济学和生态学等领域看到.
科学领域:
- 跨学科的研究涵盖经济学,神经科学,生态学,机器学习和教育.
背景情况:
- 旨在追踪目标的措施可能会失败,当它们本身成为目标时,这种现象在不同领域观察到.
- 例如,教育中的"测试教学","蛇形效应"和"古德哈特定律".
研究的目的:
- 提出和定义一个统一的机制",代理失败",以解释这些不同的现象.
- 确定代理失败的核心条件和特征,包括其作为部分失败或分歧的性质.
主要方法:
- 审查与措施目标现象相关的现有例子和术语.
- 对代理失败的理论框架的开发,分析其先决条件和约束.
- 代理失败概念应用于神经科学,经济学和生态学,以说明其范围和细微差别.
主要成果:
- 当系统受到激励或根据潜在目标的不完美的代理措施进行选择时,就会出现代理失败.
- 这种激励创造了压力,降低了代理的准确性作为真正目标的表示.

Robbers Cave
14.3K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Turbulent Flow: Problem Solving
161
Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures...

Problem-Solving

Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:

Hypothesis: Accept or Fail to Reject?
28.1K
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

IP3/DAG Signaling Pathway
12.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Self-Presentation: Self-Monitoring and Self-Handicapping
39.1K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...
