In the dialogue from "Witness in Death" by J.D. Robb, a character expresses skepticism about someone's innocence or naivety, suggesting that it is unlikely for someone to be truly guileless. The mention of Nebraska implies that people from there might be more genuine or unworldly due to their agricultural background, specifically referencing crops like soy and corn. This hints at a contrast between rural and urban life, emphasizing the perceived simplicity of those raised in rural areas.

The exchange reflects a common stereotype that individuals from less urbanized places are more innocent or less experienced in the complexities of the world. The character Peabody seems to use humor to highlight this notion, suggesting that perhaps the environment shapes people's viewpoints and behaviors. Overall, the quote conveys a deeper commentary on societal perceptions of innocence and wisdom based on geographic origins.
