What are the two examples of Sunk Costs Fallacy2. According to the speaker, what is Sunk Costs FallacyBackground InformationCognitive Bias- A cognitive bias is a pattern of deviation in judgment that occurs in particular situations, leading to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. Many cognitive biases (认知偏差) are often studied for how they affect business and economic decisions and how they affect scientific and experimental researches.Fundamental Attribution Error-A Fundamental Attribution Error (基本归因错误) is a cognitive bias in social psychology. It refers to the tendency to judge a person in an unpleasant situation in a bad light and attribute his behavior to internal causes and qualities rather than consider the situation or circumstances that may have caused the person to behave in that manner. But, if we ourselves made the same errors, we would easily attribute the causes to external factors.Confirmation Bias-A Confirmation Bias (确定性偏差) is a cognitive bias whereby one tends to notice and look for information that confirms one’s existing beliefs, whilst ignoring anything that contradicts those beliefs. It is a type of selective thinking. For example: After having bought a piece of clothing, you will look for the same clothing in a more expensive store to confirm that you have bought a bargain.Reading skillsSkimming is a method of rapidly moving the eyes over a text with the purpose of getting themain idea or a general overview of its content.
