Expectations Bias
Definition
Expectations bias refers to the phenomenon in which people distort objective judgments when making predictions or judgments about the future due to their own expectations, hopes, and preconceptions.
Explanation
For example, when a user has high expectations for a product, if the product does not meet these expectations, the user is likely to be disappointed. On the other hand, if the expectations are set low, the user is more likely to be satisfied with the same product or service. For this reason, when designing a product or service, it is possible to improve the user experience by understanding the user's expectations and using strategies to manage expectations accordingly.
Importance
Expectation bias plays a significant role in decision-making. It can affect personal choices, economic judgments, and even prognostic judgments in medical situations. In particular, excessively positive expectations can lead to discrepancies between actual outcomes and disappointment or stress.
