Generalizations are summary statements of relationships between concepts, summary statements of cause and effect, or summary statements of predictions of future relationships. Generalizations are powerful as they provide a way to consolidate information to make it more usable and easier to remember. Laws, principals, and theories are all kinds of generalizations. These generalizations require the connection of concepts by a relationship.
In contrast, generalizations are best to heighten the past. A historianâs goal is to explain what happened and why. If looking back a couple of centuries, there is less information to analyze. Therefore historian must make generalizations in order to analyze the event. Also, as the event took place decades ago the most prominent affects have already been showed. Therefore, I see it safer to generalize after a more time has passed. To make generalizations in the more recent history is unreliable. The affects of a event, such as prominent social trends are not yet shown. A shorter historical perspective of the event makes a generalization much harder. This is due to that there is more information available.
