A narrator who is affected by their own personal bias is considered unreliable.

Here's why:

* Bias distorts perspective: Unreliable narrators often have a skewed view of events due to their own beliefs, prejudices, or personal experiences. This can lead to inaccurate or incomplete information being presented to the reader.

* The reader must be critical: The reader needs to be aware of the narrator's biases to understand the true nature of events and the characters involved.

* It can create dramatic tension: Unreliable narrators can be incredibly effective in building suspense and keeping the reader guessing. The reader is constantly questioning what is true and what is not.

Some examples of unreliable narrators include:

* A character who is mentally unstable: They may not be able to accurately perceive or report events.

* A character with a strong agenda: They may deliberately manipulate the information to suit their own goals.

* A character who is deeply in love or consumed by hatred: Their emotions can cloud their judgment and lead to biased reporting.

By understanding the concept of unreliable narrators, readers can analyze the information presented to them more critically and appreciate the artistic choices made by the author.
