Which information does a geographer avoid using when defining regions

When defining regions, geographers avoid using subjective information.

Explanation:

When the information that is fed is based on personal points of view, personal opinions, irrelevant past experiences, unclear memories from the past, feelings, emotions, judgments, influenced thoughts, etc., it can be termed as subjective. This kind of information cannot be relied upon much because it is not based on solid facts and figures. If there are possibilities that the work being done would be looked at as a reference in the coming future, it is preferable to avoid relying on subjective information.
