The nature of the problem at hand determines how outliers should be treated, and there is no one-size-fits-all solution. In some cases, outliers may be genuine data points that are important to the analysis, while in other cases, they may be errors or anomalies that need to be removed. Therefore, it is crucial to understand the context of the problem and make an informed decision about how to handle outliers.
