Regression to the mean can distort outcomes from "summary" of Thinking, Fast and Slow... in 30 Minutes by 30 Minute Expert Summary Staff
Regression to the mean is a concept that describes a phenomenon where extreme outcomes tend to be followed by more moderate outcomes. This concept can have a significant impact on the interpretation of data and the understanding of cause and effect relationships. When we observe an extreme outcome, we often assume that it is the result of a specific cause or factor. However, regression to the mean suggests that extreme outcomes are often just a result of random variation. As a result, extreme outcomes are likely to be followed by more moderate outcomes simply due to the nature of random variation. This can lead to distorted outcomes because we may mistakenly attribute the more moderate outcome to a specific cause or factor when in reality it is just a natural fluctuation. This can have implications in various fields such as sports, education, and business where extreme pe...
