The peak-end rule

The peak-end rule is a psychological concept that suggests people evaluate experiences based on their most intense moments (the "peaks") and how they end, rather than the overall experience. For example, during a vacation, a spectacular sunset and a disappointing last day will shape your memories more than the average day spent there. This means that when recalling an experience, we tend to focus on those high points and how it concluded, which can significantly influence our feelings about the event as a whole.
