What are the stereotypes explored in "The Rosie Project'?

Throughout the novel, various characters have to confront the idea that their initial assumptions may not have been correct. At first, Don is quick to assume that Rosie is not intelligent because he knows that she works at a bar, and he fixates on this detail about her. However, Don subsequently learns that Rosie is highly intelligent and pursuing her Ph.D. Likewise, Rosie at first thinks Don is very strange and uptight, but she is gradually won over by his earnest desire to help her. The idea of two people forming mistaken impressions of one another and then gradually having those ideas corrected has long been a theme of romantic comedies; Austen's Pride and Prejudice is a significant example. In the end, Rosie and Don both grow and change because of their relationship with one another, but they also accept each other and alter their initial impressions to be more balanced and realistic.
