In "House Rules," Jodi Picoult explores the complexities of a family dealing with autism, focusing particularly on the character of Mark. The story presents a poignant moment where a character expresses concern that Mark's lack of knowledge about a specific diagnosis indicates a significant cognitive impairment. This perspective highlights the challenges faced by those with autism and how societal perceptions can influence the understanding of their abilities and behaviors.

The narrative invites readers to reflect on the implications of such judgments and the importance of awareness regarding psychological and developmental conditions. Through this lens, Picoult emphasizes the need for empathy and understanding, illustrating that the understanding of diagnosis is not solely indicative of one's intelligence but rather of society's preconceived notions about mental health and disability.
