From CMS 17, Section 5.254: Bias and the editor's responsibility.
"Chicago's editors do not maintain a list of words or usages considered unacceptable.... What you should strive for - if you want your readers to focus on your ideas and not on the political subtext - is a style that doesn't even hint at the issue." p. 359
Here are some techniques suggested by the Chicago editors:
- Where pronouns are concerned and the identity of the person is unknown, try to rewrite the sentence to avoid their use.
- When pronouns must be used, when possible use the pronoun preference of the person being referenced.
- Whenever possible, avoid irrelevant references to a person's sex, race, age, disability, religion, sexual orientation or social standing.
- When a characteristic is important to your writing, emphasize the person, not the characteristic.
- For words that are sex-specific (ie: "chairman", "mailman"), whenever possible, use a variant like "chair" or seek a different word like "mail carrier".
