A conservative introduction is a type of introduction that is used to provide a gradual and subtle introduction to a topic. It is often used when introducing a controversial or sensitive topic, as it allows the audience to become familiar with the topic in a more gentle manner. The term 'neo' is an abbreviation for the word 'NEW', and is often used to describe something that is modern or up-to-date. Therefore, a conservative introduction can be seen as a modern approach to introducing a topic.
