What type of obstacles do historians have to overcome to give a straight forward account of past events

Historians have to be careful of letting personal experiences, cultural backgrounds, or their own biased viewpoints cloud their work.

Explanation:

Historians have a very difficult task when they need to tell and research historical facts. This is because historical sources may contain several false accounts and true accounts may not be in accordance with the historian's principles and what he believed for this event. For this reason, the historian must be very committed to the idea of disclosing true information, so historians need to be careful to let personal experiences, cultural experiences, or their own biased viewpoints obscure their work.
