The use of specific historic evidence is what distinguishes sound generalizations from misleading oversimplifications in historians' work. Unlike generalizations, oversimplifications are always wrong. This means that historians need to base their generalizations on concrete, specific evidence from the past in order to ensure accuracy and avoid oversimplifying complex historical events. Additionally, historians should avoid making comparisons between too many historical events as this can also lead to misleading oversimplifications. Oversimplifications can often arise from asking the wrong questions or failing to consider the complexity and nuances of historical events.
