Like humans, language tends to carry biases, which can lead to discrimination. Academic writing needs to be objective and scientific: neither gender should be preferred. Historically, writing has reflected a bias towards males such as the words _________ and postman. Now, writers are more careful. Many words that included man have been replaced. For example, police officer is used instead of __________, ___________ instead of chairman, salesperson instead of _________, humankind instead of _________ and postal worker instead of __________. The title Ms is used for women instead of Miss or Mrs, since it does not show whether a woman is married or not.
chairman
policeman
chairperson
salesman
mankind
postman
