概括
人们往往忽略了减去元素来改善情况, 而是默认添加它们. 这种认知偏见阻碍了对过度劳动和环境破坏等复杂问题的最佳解决方案.
科学领域:
- 认知心理学
- 如何做出决定
- 解决问题
背景情况:
- 改善物体,想法或情况往往涉及到对可能发生的变化进行心理搜索.
- 人们通常限制他们的搜索管理认知负载, 潜在的缺失优越的替代品.
- 现有研究表明,人们倾向于增加组件,而不是减去组件.
研究的目的:
- 调查人们是否在寻求改进时同样考虑减法和增法转换.
- 确定个人是否会系统地忽视解决问题的场景中的减法变化.
- 确定影响添加与减去解决方案的默认搜索的因素.
主要方法:
- 进行了八项实验,考察参与者对增量和减量变化的考虑.
- 操纵任务线索来考虑减去, 识别增量搜索限制的机会, 和认知负载.
- 评估在不同的实验条件下识别有利的减法变换的可能性.
主要成果:
- 参与者系统地默认搜索增量转换,忽略减量转换.
- 当减法没有明确提示时,发现有益的减法变化的可能性会降低.
- 更高的认知负载和更少的机会来识别附加策略的缺陷进一步减少了对减法变化的考虑.
结论:
- 这种倾向是认知缺陷.
- 这种偏见可能导致各种现实世界挑战的不理想结果,包括个人,机构和环境问题.
- 了解这种偏见对于制定鼓励更平衡解决方案的策略至关重要.

Hindsight Biases
4.1K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

The Anchoring-and-Adjustment Heuristic
7.6K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Systematic Error: Methodological and Sampling Errors
6.1K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Fundamental Attribution Error
13.4K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Schemas
12.1K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Confirmation Biases
7.5K
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?
