Confirmation bias
During retrieval of episodic memories, people use their schematic knowledge to fill in information gaps, though they generally do so in a manner that implements aspects of their own beliefs, moral values, and personal perspective that leads the reproduced memory to be a biased interpretation of the original version. Confirmation bias results in overconfidence in personal perception and usually leads to a strengthening of beliefs, often in the face of contradictory dis-confirming evidence.
