The document discusses whether factual writing should contain bias. It notes that bias means having a prejudice for or against a group, while factual writing aims to present what is actually the case without opinion. Using bias in factual writing could confuse readers by mixing facts and opinions without an alternative perspective. However, bias could make some topics easier to discuss and engage readers if opinions are supported by facts. Overall, the document argues that factual writing generally should not include bias because its purpose is to present facts rather than opinions, though bias may occasionally be acceptable if an issue clearly has only one justifiable side.
