Nobel laureate and psychologist Daniel Kahneman shared insights from his current research about decision-making at this year’s Morningstar Investment Conference. He described noisy interferences in the decision-making process as being more important than systematic errors.
Noise is something that interferes with the decision-making process, particularly irrelevant factors influencing a person’s judgments. Irrelevant factors can include a person’s mood, how long it has been since their last meal and the weather. The order in which information is presented creates noise; if you receive the information in a different order, you will likely reach a different decision. Noise is caused by making up your mind too quickly.
How problematic is noise? Kahneman gave an example of insurance claim adjusters. A group of adjusters were given cases to analyze. The estimates from each individual adjuster were then paired to compare the differences in judgments made between them. The company’s executives expected the differences to be within an approximate 10% range. The actual difference was 50%. This was not an isolated case as a Harvard Business Review article, co-authored Kahneman, discusses.
