How does jane's naïveté serve bronte in the novel?

In Jane Eyre, Charlotte Bronte makes use of Jane’s naïveté in order to have the opportunity to satirize some actions and attitudes of the aristocracy. Throughout the novel, Bronte offers Jane’s point of view towards the British upper class, mocking some characters’ attitudes such as Mrs Reed, Mr Rochester, Ms Ingram, and her mother. Bronte not only masters the use of irony as a way to depict 18th Century-British high society but also criticizes it.
