Give an example of an author adding his or her own bias to a secondary source.

One example of an author adding their bias to a secondary source can be seen in the following scenario:

Let's say a historian is writing a book about the American Civil War and decides to include excerpts from soldiers' diaries as a secondary source. While reading through various accounts, the historian only selects and includes entries that depict the Confederate soldiers as honorable, patriotic, and fighting for a noble cause. The historian intentionally excludes any diaries that may portray Confederate soldiers in a negative light, such as instances of violence towards civilians or reports of looting.

In this example, the historian's bias is evident as they present a one-sided view of the Confederate soldiers. By selectively choosing and omitting certain entries, the historian is shaping the narrative to align with their own perspective or agenda. The inclusion of biased content can influence readers and contribute to a skewed interpretation of historical events.
