Why are subjective accounts is often biased?

Subjective accounts are often biased because they are influenced by personal emotions, experiences, and perspectives, which can distort the interpretation of events. Additionally, cognitive biases, such as confirmation bias or hindsight bias, can lead individuals to selectively remember or emphasize information that supports their views while ignoring contradictory evidence. This inherent subjectivity can result in a skewed representation of reality, making it difficult to draw objective conclusions from such accounts.
